It is triangular in shape and as wide as long (Fig. 2A). The entire preserved dorsal surface of the bone is covered by moderately deep polygonal pits limited from each other by rather low ridges. The anterolateral processes are missing. The anteriorly-projecting internasal is rather narrow and elongated. In ventral view, its spike-like outline is more evident (Fig. 2B). Only the anteromedial slot is preserved. It is long, low and not deep. In ventral view, the ventrolateral crest is broad, concave and in transverse view, triangular in outline. It starts at the base of the preserved portion of the anterolateral process and projects posterolaterally, reaching the posterior lateral tips of the frontal. The crest becomes thinner laterally. The ventral surface of the frontal, between the posterolateral crests, is flat.</p><p>Praemaxilla: Available four praemaxillae show different preservation and are not fused. The medial surface of the bone, where two praemaxillae connect with each other, possesses grooves and flanges (Fig. 2G). The width of the bone, measured along the tooth row, ranges from 1-1.5 mm. The pars dorsalis is elongated and long. In lateral view, it is curved. The laterodorsal notch is weakly developed. The pars dorsalis at its middle part extends slightly laterally, which in large-sized bones is stronger developed than in the small-sized ones. The labial surface of the bone is covered by different structures (Fig. 2C, F). The ventral portion, corresponding to the pars dentalis, is nearly smooth. The middle part of the surface, making the most of the pars dorsalis, is pierced by nutrition foramina. The tip of the pars dorsalis possesses the boss. Pustular structures and polygonal-shaped pits cover it. In labial view, the maxillary process of praemaxilla projects laterally behind the pars dorsalis. In lingual view, the well-developed suprapalatal pit at the medial base of the pars dorsalis is present (Fig. 2D, H). It has an elongate outline and reopens ventrally as a palatal foramen in the ventral surface of the pars palatinum. In medial view, the pars palatinum is curved. Distinct vomerine and maxillary processes are visible on the pars palatinum. The maxillary process is stronger developed than the vomerine one. Six to seven pleurodont teeth are attached to the pars dentalis.</p><p>Maxilla: In total, eight maxillae with different preservation are available. The pars dentalis in most well-preserved specimens possesses 13-14 teeth or tooth bases. In lingual view, the pars dentalis is high anteriorly and reduces in height posteriorly (Fig. 2J, M, P). The pars palatinum is well-developed and curved. In the middle part of the bone, it reaches its most width. The anterior tip of the pars palatinum extends anteromedially and forms a distinct process (Fig. 2J, P). The premaxillary process is well developed (Fig. 2M, P). The distinct nasal process projects anterodorsally (Fig. 2J, M). Both the dorsal and labial surfaces of the maxillae are pierced by short rows of up to three nutrition foramina, which are limited to the area around the nasal process (Fig. 2N, L, Q).</p><p>Dentary: All eleven dentaries are only partially preserved. No dentary with a fully preserved tooth row (pars dentalis) is available in the material to count the tooth number. The teeth reduce in height posteriorly. The Meckelian groove is closed and form a canal. The dental shelf is moderately broad, and its lingual margin is angular (Fig. 2R, V). The symphyseal articulation surfaces are flat and vertical. Lingually, it possesses two distinct prongs (Fig. 2R, S). The dorsal prong is long and oriented anterodorsally. The ventral one is smaller and anteroventrally oriented. The ventral prong and the main symphyseal surface are separated with a moderately deep depression, which is pierced by the anterior opening of the Meckelian groove. The latter opens posteriorly with two large ventral and small dorsal ("opening for an unnamed canal" sensu Szentesi et al. (2015); fig. 8) openings. Taking into account the “natural” cross-sections of the bones (Fig. 2U, X, Z), the split of the Meckelian canal into two branches already at the sixth tooth position can be stated. The small dorsal branch runs below the tooth row, whereas the large ventral one is enclosed in the ventral portion of the bone. The labial surface of the dentary is smooth. A row of labial foramina of different sizes is arranged along the midline of the dentary (Fig. 2T, W, Y).</p><p>Dentition: The teeth on premaxillae, maxillae. and dentary have similar morphology. All teeth are pleurodont and closely located. The tip of teeth is tricuspid with a main central large cuspid and two lateral small cuspids, which are sometimes nearly absent. The tooth pedicles are compressed anterodorsally. The tooth tip is round in cross-section. They reduce in size posteriorly.</p><p>Remarks.</p><p>The fossil remains can be assigned to the genus Albanerpeton considering the presence of the following autapomorphies (Venczel and Gardner 2005): 1) dorsal/ventral outlines of fused frontals are triangular (Character state 21(1) in Venczel and Gardner (2005)); 2) ratio of midline length of fused frontals to the width across posterior edge of bone, between lateral edge of the ventrolateral crest, is as wide as long (1:1) (Character state 22(1) in Venczel and Gardner (2005)); 3) path followed by canal through pars palatinum in praemaxillae, between dorsal and ventral openings of palatal foramen, is vertical (Character 27(1) in Venczel and Gardner (2005)). Among the species of the genus, two apomorphies of A. inexpectatum are such as; 1) the pustular ornament pattern of labial surface of premaxillary (Character 8(1) in Venczel and Gardner (2005)) and 2) form of ventrolateral crest on large, fused frontals wide and triangular in transverse view, with strongly concave ventral surface (Character 24(2) in Venczel and Gardner (2005)). Further, two character states [16(1), 17(1)] of Venczel and Gardner (2005) cannot be observed due to poor preservation of the material. The Echzell remains can be clearly distinguished from the second available European Tertiary albanerpetontid species Albanerpeton pannonicum by: 1) lack of the ventromedial keel on frontals (vs. present in A. pannonicum); 2) labial pustulate ornament on premaxilla is not restricted to the boss but also cover the surface of the bone ventrally from the boss. The presence of boss on praemaxilla has been suggested as a characteristic for A. pannonicum and should be absent in A. inexpectatum (e.g., Venczel and Gardner 2005; Szentesi et al. 2015). The structures on the dorsolabial surface of the pars dorsalis on the studied material is interpreted as boss and most probably, suggesting the character to be shared between two species.</p></div>	https://treatment.plazi.org/id/D95E7373F59A5235B1A8229D1A68E4A5	Public Domain	No known copyright restrictions apply.

Some of them are preserved in relatively good condition, perhaps due to their robust morphology as characteristic of constrictors. In lateral view, these vertebrae are as high as long. In dorsal and ventral views, they are distinctly wider than long. In the largest and best-preserved vertebra HLMD-Ez 2148, the centrum length measures 5.7 mm, centrum width - 7.2 mm, centrum length/centrum width equals 0.8. The interzygapophyseal constriction, especially in larger vertebrae, is weakly expressed. The centrum is subtriangular in shape. The haemal keel is prominent, broad and slightly broadening posteriorly. In a few vertebrae, however, the keel looks like a biconcave lens owing to the presence of a distinct constriction, located at the level of the subcentral foramina, and prominent broadenings at the anterior and posterior ends. The subcentral grooves and subcentral ridges are prominent. The neural arch is moderately depressed. The neural spine is very low (approximately three times longer than high), thick, and widening posteriorly (Fig. 18A). It occupies more than one half the length of the neural arch and begins immediately behind the zygosphenal articular facets. The zygosphenal roof is slightly convex or roughly straight in dorsal view. The prezygapophyseal and postzygapophyseal articular facets are usually subsquare in shape. The prezygapophyseal processes (if preserved) are very short and hardly visible dorsally. The paradiapophyses are subsquare in outline, higher than long, with indistinct subdivision into para- and diapophyseal portions. The cotyle and condyle are slightly flattened. The subcentral and lateral foramina are large. The paracotylar foramina are absent (Fig. 18D).</p><p>In the sole anterior trunk vertebra HLMD-Ez 2146, the haemal keel is replaced by a ventrally directed hypapophysis (its distal portion is broken). The neural spine of this vertebra is very short and relatively high in lateral view. Apart from these characteristics, the anterior trunk vertebra does not differ significantly from the middle trunk vertebrae.</p><p>Cloacal vertebra: One cloacal vertebra HLMD-Ez 2149, as characteristic for the sacral portion of the column, is provided with paired lymphapophyses (their distal ends are broken). The centrum length measures 3.4 mm, centrum width - 4.1 mm, centrum length / centrum width equals 0.8. Surprisingly, located on the ventral side of the centrum, minute but distinct paired haemapophyses are present, thus far the trait unknown in the genus Bavarioboa (see below).</p><p>Caudal vertebrae: Four caudal vertebrae are provided with paired pleurapophyses (missing or partly missing in some vertebrae). In the largest caudal vertebra HLMD-Ez 2150, the centrum length is 4.0 mm, centrum width 4.5 mm, centrum length / centrum width 0.9. Situated on the ventral side of the centrum, are short but distinct paired haemapophyses (partly broken).</p><p>Remarks.</p><p>The constrictor from Echzell displays clearly diagnostic features of the genus Bavarioboa, so among others: mid-trunk vertebrae distinctly wider than long; the interzygapophyseal constriction well expressed; the neural arch moderately depressed; the neural spine approximately as high as long, occupying one half the length of the neural arch; the haemal keel prominent; the zygosphene usually roughly straight; the prezygapophyses located clearly above the floor of the neural canal; the long axis of prezygapophyseal facets oblique in dorsal view; the prezygapophyseal processes weakly developed; the paradiapophyses subsquare in shape, with indistinct subdivision into para- and diapophyseal portions (Szyndlar and Rage 2003). By their morphological characteristics and also relatively large size, the vertebrae are similar to those of the type species, Bavarioboa hermi, occurring in the German and Czech late early Miocene (Szyndlar and Schleich 1993; Szyndlar and Rage 2003; Ivanov et al. 2020). However, the peculiar hourglass-shaped haemal keels observed in a few trunk vertebrae suggest affinities with Bavarioboa crocheti from the French late Oligocene. Interestingly, the sole mid-trunk vertebra of Bavarioboa reported from Turkey by Szyndlar and Hoşgör (2012) was provided with a similar (i.e., Bavarioboa crocheti -like) keel. Nonetheless, other morphological traits of the vertebrae from Echzell suggest that the snake represented Bavarioboa hermi or a closely related form.</p><p>There is yet another strange anatomical peculiarity observed in the sole cloacal vertebra of Bavarioboa from Echzell, namely the presence of the paired haemapophyses. This is surprising, because, in virtually all recent genera of the Boinae, haemapophyses are absent in the sacral region of the column as well as they are absent in the anterior caudals. Exactly the same morphological pattern was observed in some species of Bavarioboa, whose vertebrae coming from the sacral / anterior caudal portion of the column of which were available (Szyndlar and Rage 2003). However, there is at last one exception from this tendency in the Boinae, namely, the presence of haemapophyses was confirmed in the posterior cloacal vertebrae (as well in the anterior caudals) in the living boine Epicrates cenchria (Szyndlar, unpublished observation).</p></div>	https://treatment.plazi.org/id/35CF224F3C225FABA52DB2508CEF366B	Public Domain	No known copyright restrictions apply.

Chalcides Chalcides sp.</p><p>Fig. 12C-H</p><p>Material.</p><p>Right maxilla HLMD-Ez 1990, six right dentaries HLMD-Ez 1993-1998, one left dentary HLMD-Ez 1999.</p><p>Description.</p><p>Maxilla: One fragment of a right maxilla is preserved. The specimen HLMD-Ez 1990 (Fig. 12C, D) represents the posterior region of the maxilla. The lateral surface of this specimen is completely smooth. This maxillary fragment bears eight tooth positions with five teeth still attached). The nasal process is partly preserved. Note, however, that the dorsoventral height of the posteriorly located posteroventral process of the maxilla is still significant. Thus, it forms the wall along the entire length of the process here rather than narrowing posteriorly into a tip. Moreover, the shallow notch is developed posteriorly between the dental crest supporting teeth and the dorsally located wall. Although the posterior portion of this dorsal wall is broken off, it can be estimated that, when completely preserved, it exceeds the dental part posteriorly. The dorsal margin of the posteroventral process is slightly damaged, but this portion has a thicker appearance than the ventrally located region possessing a longitudinal depression. This depression partly forms a jugal facet. The ventrally located supradental shelf is thin and expands laterally. It is dorsally convex, but only a small portion is completely preserved. No alveolar superior foramen is preserved here. This highlights a possible anterior position of this foramen.</p><p>Dentary: The description is based on several fragments (Fig. 12E-H), most of which represent more-or-less anterior sections. The most complete specimen bears 20 tooth positions; however, its posterior region is broken off. The real tooth number is undoubtedly slightly higher. The dentary is slender, anteroposteriorly elongated. The bone gradually narrows anteriorly. In dorsal view, its anterior portion has a small medial curvature. The otherwise smooth lateral surface is pierced by several labial foramina located in the mid-portion of the bone. In medial view, the Meckel`s groove is narrow, but entirely open. The subdental shelf is medially protruded and robust, especially in the anterior region. It narrows posteriorly because of the presence of the splenial articulation facet. The symphysis is small, rectangular and somewhat narrow.</p><p>Dentition: The tooth implantation is pleurodont. The teeth are conical and high. They are closely spaced with small interdental gaps. The tooth crowns are mediolaterally compressed. Thus, the necks have a slightly lingually enlarged appearance. The tooth crowns have blunt apices. In medial view, they have a labial and lingual cusp. The lingual side, bordered by the culmen lateralis posterior and anterior, has striation formed by apicobasal ridges. They are more-or-less parallel to each other and their number usually varies from around five to eight. The labial aspect of the teeth appears smooth. Resorption pits pierce the tooth bases of some teeth.</p><p>Remarks.</p><p>All scincid elements here are assigned to one species based on the significant similarity in the dentition. Moreover, all elements are from the same locality and comparable in size. Besides tooth morphology (see Kosma 2004), the Echzell skink material can be allocated to the clade Scincidae (sensu Hedges 2014; Scincinae sensu Estes et al. 1988) based on the narrow but fully open Meckelian groove in the dentary. This is present in members of the Scincidae clade and in, e.g., Ateuchosaurus, whereas it is closed in members of Acontiidae, Sphenomorphidae, Eugongylidae, Lygosomidae, Egerniidae and Mabuyidae (see, e.g., Greer 1970, 1974; Evans 2008; Hutchinson and Scanlon 2009; Čerňanský et al. 2020b; Čerňanský and Syromyatnikova 2021).</p><p>The specimens resemble members of the genus Chalcides . The Miocene species of this taxon is represented by Chalcides augei (see Čerňanský et al. 2020b) and the Echzell material shows similarities to this taxon. Note that usually five striations are reported in Ch. augei, it can range from five to seven, and the small variation in the number of striae (from five to seven ot eight) can be seen in specimens from Austria as well ( Čerňanský 2016). However, the limitation of the Echzell material does not allow alpha taxonomy and caution is needed here.</p></div>	https://treatment.plazi.org/id/355978966049518B8F26EF3AEE1387DA	Public Domain	No known copyright restrictions apply.

Only its posterior region around the parietal foramen (sensu Gauthier et al. 2012: character 105) is available. The dorsal surface possesses well-developed ornamentation formed by large, robustly developed, and distinctly pustular protuberances (Fig. 11A). Only four are preserved (note, however, most of the dorsal surface of two of them is damaged). In the posterior region, the protuberances are large and somewhat anteroposteriorly elongated. They appear to be moderately spaced with a more-or-less complex structure (somehow resembling gomphothere molars). The internal surface of the frontal (Fig. 11B) is pierced by a small, elliptical foramen. It opens a canal that continues anterodorsally (note that the preserved dorsal surface is not pierced by it). Lateral to it, rounded, dorsally sloped ridges are well-developed. They form the border between the central, bulged region with its central shallow longitudinal depression and two additional distinct depressions located lateral to the central region. These lateral depressions become more distinct anteriorly, being gradually more recessed (in other words, the central region is deeper relative to the lateral areas). In the central region, another hole is preserved, which was most probably caused by damage.</p><p>Remarks.</p><p>Similar depressions located laterally from the central area with a foramen and being more anteriorly recessed, whereas the foramen opens a canal which continues anterodorsally, can be observed in extant Chamaeleo chamaeleon as well. The typical ornamentation formed by distinctly developed and complicated pustular protuberances, which are moderately spaced and not arranged in a ridge here, allows allocation of this cranial bone to the European Miocene chameleon Chamaeleo andrusovi Čerňanský 2010b. This species was initially described from the early Miocene of the Czech Republic ( Čerňanský 2010b) and later recognized from other areas of Europe (e.g., Georgalis et al. 2016; Čerňanský et al. 2017).</p></div>	https://treatment.plazi.org/id/DDEF56F32388509D976C3F81193F708E	Public Domain	No known copyright restrictions apply.

It bears five small teeth. The fragment is relatively massively built with a slight medial curvature at its anterior end. The bone rises dorsally, but only the base of the facial process is preserved. In medial view, the anterior internal dorsal margin has a rough surface. It can be most likely interpreted as a facet for the premaxilla. The supradental shelf is thin in medial view. However, this structure is well-expanded medially, being broad in ventral view. The external surface of the preserved section of the bone is smooth. The specimen HLMD-Ez 1962 (Fig. 11F, G) represents a posterior maxillary section - a part of the posteroventral process. It bears four teeth. In medial view, the supradental shelf is well-developed. Dorsally from this structure, the maxilla forms a longitudinal depression; a facet for the jugal is present here. The lateral surface of this fragment is smooth.</p><p>Dentary: Both dentaries are fragmentarily preserved. The specimen HLMD-Ez 1963 (Fig. 11H-J) represents the anterior portion of the left dentary. The anterior end of the dentary is curved medially, and a large elliptical symphysis is located here. This dentary fragment bears six teeth, although it should be noted that the anterior tooth is broken off. Ventrally to it, the dental groove is present, being shallow rather than deep. The well-developed and straight supra-alveolar ridge floors it. Most of the ventral portion of the Meckel`s groove is damaged. The external surface is pierced by a labial foramen located closed to the ventral margin. The specimen HLMD-Ez 1964 (Fig. 11K-M) bears only two teeth. Its lateral surface shows well-developed triangular interdental grooves (two are preserved), which incline anteroventrally.</p><p>Dentition: The tooth implantation is acrodont. Tooth size increases more-or-less posteriorly, but the dentary specimen HLMD-Ez 1964 and maxillary specimen HLMD-Ez 1962 show that at least the last posterior tooth is smaller than the adjacent anterior (probably penultimate) one. The teeth are triangular, with a low degree of tricuspidity - the central cusp is distinctly dominant. The teeth are compressed mediolaterally. The sizes of the inter-dental gaps are small in the anterior region and distinctly widen posteriorly. The large posterior teeth have wide interdental gaps. Thus, their bases are not in contact. On the posterior region of the maxilla, however, the size of the inter-dental gap between the last and the penultimate tooth is small.</p><p>Remarks.</p><p>The absence of pleurodont dentition in the anterior section of the tooth row allows the allocation to Chamaeleonidae without doubts ( Čerňanský 2010b; Čerňanský et al. 2020a). In contrast to chamaeleonids, agamids retain a trace of the primitive pleurodont condition in the anterior region (often in caniniform anterior teeth; Moody 1978).</p></div>	https://treatment.plazi.org/id/E2E43B1519BD58FF8F35CB6C017B9BF1	Public Domain	No known copyright restrictions apply.

The specimen bears 13 tooth positions with nine teeth still attached. However, its posterior region is broken off and the real tooth number is undoubtedly higher. The preserved portion of the dentary is more-or-less robust, anteroposteriorly elongated. The bone gradually narrows anteriorly. In dorsal view, its anterior portion has a small medial curvature. The otherwise smooth lateral surface is pierced by several labial foramina located in the mid-portion of the bone (five are preserved). In medial view, the Meckel`s groove is narrow, entirely open and gradually widens posteriorly. The subdental shelf is medially protruded and robust, especially in the anterior region. It narrows posteriorly because of the presence of the splenial articulation facet. The symphysis is rectangular.</p><p>Dentition.</p><p>The tooth implantation is pleurodont. The teeth are conical and high. They are bicuspid with a dominant distal cusp and smaller accessory mesial cusp. However, the anteriormost dentary teeth are monocuspid, becoming bicuspid starting from the sixth to seventh tooth position. The lingual aspect of the tooth crowns has very fine vertical striations, and the tooth necks bulge slightly medially, with small interdental gaps.</p></div>	https://treatment.plazi.org/id/CD15718FFDD557F3B94B24C8A583175D	Public Domain	No known copyright restrictions apply.

In dorsal view, the most anterior portion of the bone possesses an articulation facet with the parietal that is covered by parallel to each other ridges. Comparison with recent similar-sized species shows most similarities with Salamandra salamandra (MJSN-OS 806). However, due to the lack of comprehensive studies of the skull bones among salamandrids, an allocation of the bone to the family Salamandridae is more appropriate.</p><p>The vertebrae are poorly preserved. They show ophistocoelous morphology partially with complex structures of haemal and neural processes, characteristic of the caudal region of the vertebral column (Duellman and Trueb 1994). On the one hand, the poor preservation and, on the other hand, the poor knowledge on osteological differences of the caudal region in Chelotriton and Salamandra genera (both present in the fossil locality) make it at the moment impossible to identify the vertebrae correctly.</p><p>Nine small-sized opistocoelous vertebrae are available in the material. They have variable preservation; however, a large number of structures/characters are missing for further identification. Considering the vertebra sizes as well as available similar-sized salamander taxa present in the material, most probably, they represent remains of Lissotriton, Mertensiella or Chioglossa . The juvenile and most distal caudal vertebra of Salamandra and Chelotriton can be excluded because in the former form the juvenile vertebrae are not fully ossified, whereas in the latter the dorsal tip of the neural crest possesses a ornamented surface, which is missing here.</p><p>Two bicapitate rips are present (Fig. 6P-S). Their lateral portion does not possess any process, which allows to exclude them from Chelotriton . Most probable, they should belong to the genus Salamandra, which has a similar rib morphology and is represented in the material by large-sized individuals as well.</p></div>	https://treatment.plazi.org/id/FC89A98367C45B4798C21B729E4C7F14	Public Domain	No known copyright restrictions apply.

They represent individuals of different sizes. The frontal is widest at its most complete posterior portion. Its dorsal surface is covered by dermal ornamentation (Fig. 5G, I, K). The bone is slightly bent along its midline between the fronto-squamosal arch (sensu Ivanov 2008) and the rest of the bone. The fronto-squamosal arch projects posteriorly behind the main part of the bone. In ventral view, the partes contactae are reduced and run parallel along the anteroposterior axis of the bone. The braincase roof, located medially from the pars contacta, is delimited by a low crest of a semilunar outline (Fig. 5H, J, L).</p><p>Prefrontal: The prefrontals are wing-shaped bones, anteriorly broad and posteriorly narrowing to a sharp tip (Fig. 5M-N). The lateral margin (margo orbitalis) of the bone forms the anterodorsal wall of the orbit. The anterior corner of the margo orbitalis is pierced by the foramina of the V nerve. In ventral view, the ventral vertical wall separates the margo orbitalis from the rest of the bone. The articulation surface with the frontal bone, located at the posterolateral margin of the bone, is massive and more strongly developed than any other margin of the bone.</p><p>Nasal: The nasal bone has a nearly rectangular outline (Fig. 5O-P). All its margins are flat, without any concave outlines. Its dorsal surface is slightly rounded and possesses dermal ornamentation. In ventral view, parallel to the medial margin of the bone a ridge for articulation with the premaxillae is present.</p><p>Maxilla: only the posterior portions of the bone without dentition are present in the material. In dorsal view, the bone is narrow and a thin-walled horizontal pterygoid process projects lingually (Fig. 5S, U). In lateral view, the bone surface is covered by dermal ornamentation made of a dense network of small pits and pustules. Posteriorly the bone increase in height. In lingual view, the bone surface is smooth (Fig. 5R, T). The articulation surface with the quadratojugal bone is located on the posterodorsal surface of the bone. The size and dimensions of the articulation surface vary among available maxillae.</p><p>Squamosal: Two squamosals are partially preserved. In dorsal view, the HLMD-Ez 2066 is nearly semilunar in outline (Fig. 5V). The frontal process is curved slightly medially and possesses a vertical and almost flat articulation surface with the frontal. The lateral margin of the bone is rounded. The dorsal surface of the bone is somewhat horizontal and is covered by dermal ornamentation similar to other skull bones. The parietal process (in HLMD-Ez 2067, Fig. 5X) has a horizontal surface. It is slightly shorter but broader than the frontal process. In ventral view, a medioposteriorly oriented ridge, corresponding to the base of the ventral process of the bone, is visible. Posteriorly from the ridge, the bone surface is moderately concave.</p><p>Dentary: The fragmentary-preserved dentary is 1.7 mm in height. In lingual view, it shows a very low dental shelf with traces of the tooth pedicles. The preserved portion of the Meckelian groove is narrow and rather shallow (Fig. 5Z). Another but smaller groove is observable below the posterior half of the Meckelian groove, resembling most probably the articulation surface with the coronoid. In lateral view, the dentary is heavily ornamented by pits and pustules (Fig. 5Y). A remarkable concave surface separates the portion of the dental shelf from the rest of the bone.</p><p>Trunk vertebrae: the vertebrae are robust. The opistocoelous vertebra centrum is massive and slightly dorsoventrally flattened. The neural crest is nearly as high as the vertebra centrum (Fig. 6B, I). In dorsal view, its dorsal surface possesses a flat and (elongate) triangular in outline plate, which is covered by a dermal ornamentation made of deep pits and low pustules (Fig. 5A, H). This place can be well developed and projects over the neural arch. Anteriorly, the neural crest does not reach the anterior tip of the neural arch (Fig. 6D, F). The pre- and postzygapophyses are round or elongated and project (latero-)anteriorly. The neural arch between the anterior half of the prezygapophyses has a smooth and convex surface. In anterior view, the neural canal is rounded or nearly triangular in outline (Fig. 6F). The condyle has a dorsoventrally flattened oval shape.</p><p>Small subprezygapophyseal foramina (sensu Vasilyan et al. 2017) can be present at the basis of the prezygapophyses. In lateral view, the transverse process is connected with the postzygapophysis by a clearly visible dorsal lamina (Fig. 6B, I). The posterior alar process connecting the parapophysis with the cotyle is smaller than the dorsal lamina. The prezygapophysis is connected with the parapophysis by a well-developed accessory alar process. A very thin anterior alar process connects the base of the prezygapophysis with the parapophysis of the transverse process. In ventral view, rather large-sized subcentral foramina and rather smaller foramina are visible on the ventral surface of vertebrae. The transverse process consists of para- and diapophysis, which, though located close to each other, are separated by a thin lamina (Fig. 6B). In posterior view, the pterygapophysis possesses two distinct notches.</p><p>Ribs: All ribs are fragmentarily preserved. The articulation joints with the transverse process of the vertebrae are bicapitate. Both articulation heads are rounded and connected with a thin bone lamina (HLMD-Ez 2053, Fig. 6L). The dorsal surface of all ribs possesses two (HLMD-Ez 2054, Fig. 6K) to five (HLMD-Ez 2055, Fig. 6M) spines of different sizes and orientations.</p><p>Remarks.</p><p>Based on the combination of the following characters, the described fossil remains can be attributed to the genus Chelotriton, broadly known from the Cenozoic deposits of Europe: 1) the presence of the characteristic dorsal ornamentation on skull bones and the horizontal plate of the neural spine of vertebrae; 2) the pterygoid process of the maxillae connected with the pterygoid; 3) the presence of spines on the ribs and 4) general morphology and dimensions of the bones (Ivanov 2008; Schoch et al. 2015; Vasilyan 2020). The remains cannot be clearly assigned to any known species of the genus due to the lack of a comprehensive understanding of the taxonomic diversity within the Chelotriton genus. However, some comparative remarks can be given below. The described skull bones differ significantly from all so far known Chelotriton records. For example, the frontal shows an intermediate morphology observable in Chelotriton sp 1. and sp. 2 from Mokrá-Western Quarry, Czech Republic, early Miocene (Ivanov 2008) and Chelotriton paradoxus from the Enspel Maar, Germany, late Oligocene, and Randecker Maar, Germany, early Miocene (Schoch et al. 2015). The shape of the squamosal in the Echzell material can be found only in Chelotriton sp. from Orsberg, Germany, late Oligocene ( Marjanović and Witzmann 2015), where a bone of a similar shape is named as a quadratojugal-quadrate bone. The nasal from Echzell (nearly rectangular in outline) can be clearly distinguished from that of all known forms in which the form varies from irregular-shaped one (e.g. in Chelotriton paradoxus from Enspel, Roček and Wuttke 2010) to trapezoid-shaped in Chelotriton sp. form Orsberg ( Marjanović and Witzmann 2015). Most probable, the suggested high variability of the skull bone (Schoch et al. 2015) can be explained by uncovered high specific diversity of Chelotriton . Thus, at this stage of knowledge, we describe the fossil remains of Chelotriton with an open nomenclature.</p></div>	https://treatment.plazi.org/id/14130CC99D4F5FC38573A8624152D9BF	Public Domain	No known copyright restrictions apply.

In ventral view, a number of ridges and structures are visible (Fig. 8B, D, F); however, due to their preservation, any further description/anatomical identification is impossible.</p><p>Maxillae: All bones are fragmentarily preserved. Their labial surface is smooth and does not possess any ornamentation (Fig. 8G). Only in (HLMD-Ez 2132), the labial surface is covered by some irregularities. In lingual view, the horizontal lamina has a rounded surface and reduces height anteriorly (Fig. 8H). Posteriorly, it terminates with a medioposteriorly projecting pterygoid process. The posterior depression is moderately developed. The margo orbitalis is slightly concave.</p><p>Prooticoccipital: One preserved prooticoccipital (HLMD-Ez 2127) consists of both fused prootic and lateral occipital processes (Fig. 8I-L). It displays a distinct supracondylar depression. The prominentia ductus semicircularis posterioris is present as a distinct crest. It starts at the base of the lateral prootic process and projects medioanteriorly until the articulation surface with the frontoparietal. A foramen is present at the ventral base of the lateral prootic process. The sulcus venae jugularis is present as a horizontal groove. The fenestra ovalis is massive (Fig. 8K).</p><p>The atlas has a dorsoventrally flattened centrum (HLMD-Ez 2116, Fig. 8N). The neural arch is not preserved. The crista ventralis is well developed. The condyloid fossae are separated from each other by a notch. The opisthocoelous presacral vertebrae have massive, slightly dorsally compressed centrum. The transverse processes project laterally. The neural arch in a small-sized vertebra projects posterodorsally (HLMD-Ez 2118), and the neural spine is clearly visible (Fig. 8O, P). The sacral vertebrae have one anterior and two posterior condyles with very rounded external surfaces (Fig. 8X, Y). The neural arch is short. It measures as long as the bases of the transverse processes. The latter widens laterally and project lateroposteriorly. The prezygapophyses in both presacral and sacral vertebrae project laterodorsally (Fig. 8S, W).</p><p>The urostyle possesses two condyloid fossae and two lateroposteriorly bending transverse processes (Fig. 8Z, AA). The opening of the neural canal is rounded. The neural canal opens dorsally behind the transverse processes in the form of a narrow and long strip.</p><p>The preserved ilia have low or moderately developed dorsal prominence. The dorsal protuberance has a flat surface and shows high variation in shape and size. It can be very reduced in the form of a small protuberance (HLMD-Ez 2137, Fig. 8AB) or rather well-developed elongate (HLMD-Ez 2140, Fig. 8AF) or short drop-shaped (HLMD-Ez 2140-2141, Fig. 8AF) structure. It is connected with the lateromedially compressed iliac shaft by a thin lamina which reduces in height anteriorly behind the dorsal protuberance. The acetabular region is well developed. The dorsal acetabular expansion is well-developed and has a triangular outline. The ventral acetabular expansion is rather reduced and widens ventrally, expanding below the ventral margin of the acetabular crest. The ventral portion of the acetabular crest is well developed and projects ventrolaterally. The supraacetabular fossa is absent or, if present, weakly developed. A distinct tubercular fossa is visible in the corner between dorsal prominence and iliac shaft. In both medial (Fig. 8AE, AI) and posterior views (Fig. 8AH), a well-developed interiliac tubercle is visible. In posterior view, the ilioischiatic juncture can be clearly divided into a massive ventral and a slender dorsal portions, which are delimited in the medial surface by a deep groove.</p><p>Remarks.</p><p>The herein described remains can be assigned to the genus Latonia based on the presence of the following features: 1) frontoparietal with the characteristic tubercular sculpture; 2) prooticooccipital bone with a distinct supracondylar depression; 3) atlas possessing ventral crest; 4) urostyle with lateroposteriorly projecting transverse processes; 5) the general morphology of ilium and presence of the interiliac tubercle etc. ( Roček 1994).

The condyle is shorter and slightly smaller than the cotyle. The pericondylar constriction is well pronounced. The anteriorly oriented prezygapophyses have an oval outline. In dorsal view, the neural arch has a weakly-pronounced sandglass shape, where the narrowest part is located behind the prezygapophyses. The posterior margin of the neural arch is either flat or slightly bifurcated. The posterior notch is well preserved and visible on HLMD-Ez 2047 (Fig. 4E). The neural spine starts behind the anterior margin of the neural arch and reaches the posterior tip of the latter (Fig. 4B, G). The neural spine is always missing; however, where it is preserved, no ornamentation can be observed on it, and its rather large height can be suggested. The pre- and postzygapophyses are connected by a well-pronounced (nearly) horizontal interzygapophyseal crest, which covers slightly the proximal part of the transverse process (Fig. 4B). The transverse process is composed of the dia- and parapophysis, which in turn are connected by an osseous lamina along their length. In ventral view, the anterior and poster processes form a distinct ventral lamina of triangular to irregular rhomboidal shape (Fig. 4C, H). It is pierced by two smaller subcentral foramina near the center of the vertebra centrum. The anterior alar process is larger than the posterior one. The opening of the spinal nerve is visible behind the transverse process at the base of the neural arch. In anterior view, the neural canal is large (larger than the diameter of the condyle) and has a round or slightly expressed pentagonal outline (Fig. 4D, I). In posterior view, the neural canal is also large and has a round or slightly elliptical outline (Fig. 4E, J).</p><p>Remarks.</p><p>The remains can be clearly assigned to the genus Lissotriton considering their small sizes; the lack of the dorsal widening or any structures on the neural spine; the presence of a well-pronounced rhomboid/triangular ventral lamina on the vertebral centrum (Ivanov 2008; Georgalis et al. 2019). On the one hand, poor and partial preservation of vertebrae and, on the other hand, not adequate knowledge of the osteology of the Lissotriton genus does not allow any further allocation at species or species group levels.</p><p>Salamandra Garsault et al., 1764</p></div>	https://treatment.plazi.org/id/CE41F089CBC550E5BEFF8DE94D0DA388	Public Domain	No known copyright restrictions apply.

The largest vertebra, coming from the middle trunk portion of the column HLMD-Ez 2159 (Fig. 18F-J), belonged to a relatively small-sized snake (centrum length measures 4.5 mm, centrum width - 3.6, centrum length / centrum width ratio equals 1.25). It lacks both prezygapophyseal processes and right postzygapophysis. The centrum of most vertebrae is subtriangular in ventral view and slightly longer than wide in the largest vertebrae. In a number of smaller vertebrae, interpreted as posterior trunk vertebrae, the centrum is more elongated. The subcentral ridges are well developed. The haemal keel is distinct and slightly widening before reaching the condyle base. The neural arch is moderately vaulted, not accompanied by any epizygapophyseal spine. The neural spine (partly preserved in few vertebrae only) is twice longer than high approximately. The zygosphenal roof (preserved in few vertebrae) is roughly straight or consisting of three indistinct lobes. The prezygapophyseal articular facets are oval (Fig. 18G), the postzygapophyseal facets are usually subsquare in shape (Fig. 18H). The prezygapophyseal processes are damaged in all vertebrae. Remnants of the processes preserved in one (?posterior) vertebra indicate that the apophyses may have been slender and relatively long (as long or almost as long as the prezygophyseal articular facets). The paradiapophyses (usually eroded) are moderately developed, with the dia- and parapophyseal portions of roughly equal length (Fig. 18I). The cotyle and condyle are slightly depressed dorso-ventrally. The lateral, subcentral and paracotylar foramina are small but distinct.</p><p>Remarks.</p><p>Owing to the bad preservation state of the aforementioned remains, we refrain from identifying the fossil snake to the genus level. The remains resemble roughly those of a number of small “colubrines” (i.e., " Colubridae " devoid of hypapophyses throughout the column) reported from several early Miocene sites (Szyndlar 2012). We cannot exclude the possibility that the fossils belonged to more than one taxon, but it cannot be proved.</p></div>	https://treatment.plazi.org/id/582E10CB531754898341C6ED8194E1C4	Public Domain	No known copyright restrictions apply.

They are tubular, with acute distal tips. The discharge orifice, located on the anterior surface of each fang, is elongate and gladiate-shaped. The discharge orifice extends, towards the proximal end, in the form of a visible suture. The latter condition is characteristic of elapid snakes, whereas in viperids the anterior surface of the fang is generally smooth. Relatively small dimensions of the fangs suggest that they either belonged to juvenile / subadult individuals or were replacement (non-functional) fangs.</p><p>Vertebrae: Most vertebrae come from the middle trunk portion of the column. In the largest (but partly damaged) vertebra (HLMD-Ez 2151, Fig. 18K-O), centrum length measures 7.1 mm, centrum width - 5.7 mm, and centrum length / centrum width ratio equals 1.25. At least in large vertebrae, the centrum is triangular in ventral view, with a flat or slightly concave ventral surface. The subcentral ridges are well developed, especially behind the paradiapophyses. The hypapophysis, preserved partly in few vertebrae, is thick, strongly inclined posteriorly and shows a straight anteroventral margin. The neural arch is rather depressed. The neural spine, preserved partly in few vertebrae, is approximately twice longer than high. Its anterior margin is straight. The shape of the posterior margin is unknown. The paradiapophyses are well developed with short but distinct parapophyseal processes (the latter is preserved only in two vertebrae). The zygosphenal roof is almost straight or slightly convex in dorsal view. The prezygapophyseal and postzygapophyseal articular facets are relatively small and oval-shaped. The prezygapophyseal process (preserved only on the left side of one vertebra) is well developed, somewhat shorter than the articular facet and possesses also a moderately obtuse tip. The cotyle and condyle are suborbicular or slightly depressed. The subcentral, lateral, and paracotylar foramina are distinct (Fig. 18K-M).</p><p>A few trunk vertebrae coming from the posterior trunk portion of the vertebral column are more elongated than those from the middle portion. One vertebra (HLMD-Ez 2154; centrum length 4.1 mm, centrum width is 3.0 mm, centrum length / centrum width ratio 1.4) is provided with a completely preserved hypapophysis. The hypapophysis is dagger-shaped and directed posteriorly.</p><p>Remarks.</p><p>Based on the overall vertebral morphology, cobras can be rather easily differentiated from other European fossil snakes. The vertebrae of cobras “mimic” the morphological pattern characteristic of large-sized “colubrines” but, unlike the latter, they are provided with hypapophyses throughout the trunk portion of the column. The vertebrae described above generally display the anatomical features characteristic (e.g., dagger-shaped and posteriorly directed hypapophysis) of the extinct species Naja romani (Szyndlar 2005). Considering the fragmentary state of preservation of the fossils, we prefer to use the species name with the qualifier “cf.” .</p></div>	https://treatment.plazi.org/id/F2F61C839C4857E6BD63B16A4E759B22	Public Domain	No known copyright restrictions apply.

Its anterior portion, at the level of the anterior orifices of the Vidian canals approximately, is missing. The maximum width of the bone, measured between distal tips of the basipterygoid processes, is 3.7 mm. In ventral view, the basisphenoid crest is absent (Fig. 18A, B). The basipterygoid processes are distinct. Their posterior margins are strongly extended posteriorly covering the recess housing the posterior foramina of the Vidian canals. However, a tiny proximal fragment of the left basipterygoid process is broken off, owing to which the posterior orifice of the Vidian canal as well as the cerebral foramen (for palatine branch of facial nerve, VII) are clearly visible in ventral view.</p><p>In dorsal view, several foramina are visible, distributed typically of higher snakes (Fig. 18C, D). The paired largest foramina, located at the midway between the posterior border of the bone itself and the posterior border of the pituitary fossa (sella turcica), are posterior openings for the abducens nerves (VI). The anterior openings for these nerves are situated near the postero-lateral corners of the pituitary fossa. The sympathetic nerve foramina (not visible on the right side) are located directly anterior to the pituitary fossa. The paired openings piercing the basipterygoid processes, laterally to the abducens nerve foramina, are tentatively interpreted as the deep petrosal nerve foramina (both visible on the left side only).</p><p>Seen in left lateral view, an opening located directly above the posterior orifice of the Vidian canal and partly hidden beneath the basipterygoid process, is interpreted as a foramen for re-entry of the constrictor internus dorsalis branch (cid) of the trigeminal nerve (V4) on its way from the prootic (Fig. 19E, F). The location of the exit of the latter nerve (either within the basisphenoid or in a suture between the basisphenoid and parietal) remains unknown owing to the damage of the bone anterior to the basipterygoid processes.</p><p>Remarks.</p><p>Apart from the basisphenoid, the available snake material from Echzell does not contain any other elements, in particular vertebrae, identifiable as belonging to natricine snakes. This absence of any vertebrae is astonishing, considering that in virtually all fossil sites, if they yield snake cranial remains, the latter are typically accompanied by vertebrae. Unfortunately, this is not the case of the material from Echzell. Theoretically, some vertebral fragments classified here as " Colubroides indet." could belong to natricines, but it cannot be proved on the studied material.</p><p>The basisphenoid from Echzell is clearly referable to the extinct snake Natrix longivertebrata . By its peculiar morphology, it significantly differentiates not only from basisphenoids of other natricines (except for N. astreptophora, see below) but also from those belonging to members of other ophidian families (Szyndlar, unpublished observations).</p></div>	https://treatment.plazi.org/id/29F53A2B83E55FD181D9339FFB7F7C4B	Public Domain	No known copyright restrictions apply.

It represents the area around the superior alveolar foramen plus the section of the posteroventral process. This maxillary fragment bears eight tooth positions (one tooth is still attached). The otherwise smooth lateral surface is pierced by the labial foramina - three and a half are preserved. The medial side bears the well-developed supradental shelf. At the level of the fifth tooth position (counted from posterior), the shelf expands medially to form the palatine articulation. At this level, the superior alveolar foramen is located on the dorsal side of the shelf. Only the base of the nasal process is preserved; the rest of the bone is broken off. The posterior portion gradually narrows into the posteroventral process. Its dorsal margin smoothly decreases ventrally without being stepped.</p><p>Dentary: Two dentary fragments are preserved, both representing only the posterior portions (Fig. 15C-F). The right one (HLMD-Ez 1967) possesses five tooth positions, where the penultimate and fourth (counted from posterior) are still partly preserved. Except for two labial foramina, the lateral surface is smooth (only one foramen is preserved in HLMD-Ez 1968). The medial surface exhibits open Meckel`s groove, which narrows anteriorly. It is roofed by the concave, shallow subdental shelf. The position of the anterior inferior alveolar foramen between the dentary and a splenial can be recognized at the level of the fifth tooth position, but this area appears to be eroded. The alveolar foramen is located at the level of the third tooth position. The intramandibular septum, which separates the alveolar canal from Meckel`s groove, is completely fused with the body of the dentary (the free ventral portion is absent). The surangular spine is damaged, so only its root portion can be recognized. The angular process is broken off. The other posterior processes are damaged. The left dentary HLMD-Ez 1968 represents a specimen with four tooth positions - only one complete tooth and the base of another one are still preserved. The position of the anterior inferior alveolar foramen can be still recognized on the subdental shelf. The splenial spine is absent in both specimens. Due to poor preservation of this area, however, this appears to represent a postmortal damage only.</p><p>Dentition: The tooth implantation is shallowly pleurodont. The teeth are large, well exposed over the dorsal crest, which supports them laterally. They are conical and distinctly recurved. Their tips are pointed. The mesial and distal cutting edges are well developed. The tooth bases are broad, being pierced by resorption pits. In most cases, the pits are located slightly posterior to the tooth axis. The dentary teeth are smooth by weathering (or affected by digestive process of carnivores), the maxillary tooth crown possesses fine but dense striations on both labial and lingual sides.</p><p>Dorsal vertebra: The description is based on the well-preserved specimen HLMD-Ez 1969 (Fig. 15G-J). The vertebral centrum is anteroposteriorly elongated. The height of the vertebra gradually increases posteriorly. The neural spine is low, however, its dorsal portion is broken off. It forms a ridge running along almost the entire length of the dorsal section of the neural arch. In dorsal view, the ridge is thin, becoming less distinct in the anterior section. In the posterior third of its length, it is well defined and widens at its posterior end. The neural canal is high and well arched dorsally. The cotyle is depressed, being mediolaterally expanded and broader than the neural canal. However, the maximum height of the cotyle is lower than the maximum dorsoventral height of the neural canal. The pre- and postzygapophyses are well expanded laterally; a well-developed interzygapophyseal constriction is located between them. The pre- and postzygapophyses have elliptical articulation surfaces, oriented more or less anteroposteriorly. The prezygapophyses are inclined from the horizontal plane at an angle of approximately 30°. The synapophyses are protruding laterally, being square in shape. The condyle, which is well-protruded posteriorly, is markedly depressed as well as the above-mentioned cotyle. The ventral surface of the centrum is flat. It is pierced by two subcentral foramina in the anterior one-third of the centrum. The lateral margins of the centrum have a concave course, running more anterolaterally from the level of the subcentral foramina.</p><p>Remarks.</p><p>Among extant anguine genera, the morphology of herein described vertebrae resembles that of Ophisaurus ( Čerňanský et al. 2019). The maxilla with markedly recurved teeth and vertebrae similar to those from Echzell have been described also from Gratkorn (see Böhme and Vasilyan 2014). Such a distinct tooth curvature is not very typical among members of extant Ophisaurus (see Klembara et al. 2014), but can be found in fossil species, e.g. in O. acuminatus (see Klembara and Čerňanský 2020). However, it should be noted that some features in the dentary, such as the presence of a splenial spine, cannot be supported with confidence due to poor preservation. Moreover, another crucial reason exists why the allocation of this material to Ophisaurus might be problematic - the occurrence of a new taxon Smithosaurus echzellensis in both Echzell and Gratkorn localities. We cannot entirely exclude the very plausible option that some of those specimens (if not all) belong to this newly described taxon. For this reason, we allocated this material only as Anguinae indet. Caution is also needed in regards to interpretations of isolated jaw fragments and isolated vertebrae from other European Miocene localities, where such incomplete and fragmentary materials are often described as Ophisaurus . More complete and articulated material of Smithosaurus echzellensis, in which bones can be associated together to observe the anatomy of this taxon, is crucial to resolve this problem.</p></div>	https://treatment.plazi.org/id/DC75F998A42E5025BDD32FDB952ABD09	Public Domain	No known copyright restrictions apply.

It is almost fully preserved. It is a single, unpaired T-shaped element (note, a groove or break is running through the midline, see remarks). The premaxilla bears seven-tooth positions with three teeth still attached to the dental parapet. The laterally extended maxillary processes are well developed. They are rather short than long. They possess an articulation facet for the maxilla on their dorsolateral surfaces. The fragmentarily preserved nasal process is wide, its external surface is flat. Here, a few small vestiges of osteoderms attached to the bone are present. In anterior and posterior views, the base of the nasal process is laterally constricted. Thus, the lateral margins in the lowest region of the process are rounded, having a cut-out like appearance. Dorsally, this region is wide, having more-or-less parallel lateral margins. The most dorsal preserved portion of the process narrows abruptly again, but the rest of the process - the posterodorsal portion with a termination - is broken off. On the internal side, there is a sagittal ridge running along the entire length of the preserved nasal process. It separates the facet for the nasals on both sides. On the lateral side, the ethmoidal foramen is located close to the base of the nasal process. The supradental shelf is formed by two segments, which are well expanded posteriorly. The dorsal side bears the vomerine process, which forms a small bulge. The short, weakly bilobed median incisive process is located ventral to the supradental shelf.</p><p>Remarks.</p><p>Although the right and left premaxillae are fused, note that there is a fracture-like structure (or a tiny groove) running through the central portion of the element. However, it is unclear whether this is postmortal damage only or reflects the fusion of the right and left premaxillae during ontogeny. Even if it is only a fracture caused by damage, the central region might be weaker due to the late fusion and, thus, prone to breakage when pressure is applied. Among Chalcides species, a groove indicating a fusion is often present in various degrees (for Ch. ocellatus, see Digimorph.org 2002-2012; in some, e.g., Ch. polylepis, the right and left premaxillae are separated; see, e.g., Caputo (2004); pers. obs. of A. Č .). However, its lacertid affinity can not be excluded. The premaxilla of lacertids is formed by a single element (see, e.g., Čerňanský and Syromyatnikova 2019). If the specimen HLMD-Ez 1989 represents a lacertid, the present groove is caused by postmortal damage only. In any case, we decided to allocate this specimen to Squamata indet.</p><p>Quadrate: A right quadrate is available in the material (Fig. 17D, E). It is a slender, dorsoventrally elongated element. In lateral view, the quadrate is anteroposteriorly narrow, with an anteriorly expanded, rounded anterior margin. Here, the sharp and laterally expanded tympanic crest is present. This crest is continuous from the cephalic to the mandibular condyle. The crest is slightly angled approximately in the mid-region. Further dorsally, it fluently and gradually continues without being distinctly separated by a sharp angle from the portion formed by the cephalic condyle. The dorsal portion of the cephalic condyle protrudes slightly posteriorly. The ventral half of the quadrate narrows gradually ventrally. The ventral region ends with the saddle-shaped mandibular condyle. It is slightly smaller than the cephalic condyle. The medial surface possesses a distinct medial crest. Posterior to this crest, the bone is pierced by a quadrate foramen located in the ventral one-third of the dorsoventral height of the element.</p><p>Remarks.</p><p>The morphology of the quadrate HLMD-Ez 2002 is similar to that of lacertids (see e.g., Čerňanský and Syromyatnikova 2019) rather than anguids. Note, however, that the general shape of the lacertid quadrate resembles that of scincids (see Villa and Delfino 2019b),</p><p>Pterygoid: The left pterygoid is incompletely preserved (Fig. 17F, G). It is a tri-radiate, Y-shaped element. Its ventral portion bears a distinct dentition located in the central region. Only the base of the ectopterygoid process is preserved, being broad. From its posterior region, a sharp crest runs to the quadrate process. Here, the crests border a fossa located laterally on the process. The quadrate process is long but note that its end is broken off. The fossa columellae (= epipterygoid fossa), which is present on the dorsal side, is large and elliptical.</p><p>Identification of isolated elements as pterygoids is problematic and caution is needed. However, the morphology of HLMD-Ez 2003, e.g., the absence of the obtuse process (ventromedial process sensu Conrad 2008), indicates that we can exclude Anguidae here. Its morphology, including the crests bordering a fossa located laterally on the quadrate process, resembles skinks. Although note that dentition is absent in e.g., Chalcides occelatus, but present in, e.g., Plestiodon fasciatus (see Caputo 2004; Digimorph.org 2002-2012).</p><p>Osteoderm: Two osteoderms are available in the material. The larger osteoderm HLMD-Ez 2000 (Fig. 17H-J) is roughly trapezoidal in shape. It is thick, with distinct external bulging. Its external surface expands in the anterior direction, being gradually more pronounced. This gives a convex appearance in cross-section. The whole osteoderm gradually narrows anteriorly. Here, the well-developed anterior overlap surface is located, forming one-third of the entire anteroposterior length of the osteoderm. Its anterior mid-region bears a short groove, which is present on the internal side as well. The region posterior to the overlap surface bears ornamentation. The ornamentation appears to be rather weak and not dense, being formed mostly by ridges and pits, connected by short grooves in some cases. The medial ridge is absent. The internal aspect of the osteoderm is not flat, but is rough. It has several irregularly distributed pits, foramina, and a few grooves near the posterior end.</p><p>The smaller specimen HLMD-Ez 2001 (Fig. 17K-M) is wide. Its width is slightly greater than its anteroposterior length. The anterior portion, which bears a narrow overlap surface, is triangular, whereas the posterior portion has a round margin. The osteoderm is thick, although note that it is narrower relative to its size if compared to the larger one. Here, the internal surface of the smaller osteoderms is slightly concave. The ornamentation of the external surface is formed by densely spaced ridges and grooves running from the ossification centre; those ones located on the periphery are prolonged.</p><p>The differences in these two osteoderms can be caused by ontogeny and different origins regarding the body topology. Overall, this type of osteoderms resembles the osteoderms described by Čerňanský (2016; fig. 11) as Squamata indet. 2 from the lower Miocene of the Austrian locality Oberdorf. They might very likely belong to skink.</p></div>	https://treatment.plazi.org/id/242FB745A2AA54059E5476329C709970	Public Domain	No known copyright restrictions apply.

It bears 16 tooth positions that are densely spaced. Unfortunately, all teeth are broken off and missing, except for two preserved tooth bases. The dentary is slender (note, however, that the alveolar crest is high). In medial view, it gradually widens posteriorly and Meckel`s groove is fully closed. The ventral margin of the dentary is slightly concave. Besides three labial foramina, the external surface of the bone is smooth.</p><p>Vertebra: Only one isolated dorsal vertebra is preserved (Fig. 10C-G). The vertebra is small, lightly built and anteroposteriorly elongated. It is amphicoelous with the centrum pierced by a notochordal canal. On the dorsal surface of the low neural arch, a straight dorsal and longitudinal, almost indistinct crest is present along the surface of the neural spine. The neural spine is weak, and it does not rise dorsally. However, the posterior region of this area is damaged, and the right postzygapophysis is broken off. On the anterior side, a deep and wedge-shaped notch is present (note, that it is unclear how much its contour is a result of potential breakage and/or normal state). Both pre- and postzygapohyses are almost anteriorly and posteriorly directed. The neural canal is large and heart-shaped because of the rounded centrum that is located ventrally. In lateral view, there is an elliptical synapophysis. In this view, the centrum has a concave ventral margin. In ventral view, the lateral margins of the centrum are concave as well. In the central region, a short ridge is developed between the anterior and posterior portions of the centrum. Laterally from the ridge, the surface is pierced by a pair of subcentral foramina.</p><p>Remarks.</p><p>In the European Miocene, the sphaerodactylid genus Euleptes is often present (see e.g., Daza et al. 2014; Čerňanský et al. 2018). Extinct genera of Gekkota are represented by Gerandogekko, which has been identified as closely related to Euleptes (Daza et al. 2014) and Palaeogekko (Schleich 1987). The material from Echzell is, however, too fragmentary for a generic assignment.</p></div>	https://treatment.plazi.org/id/D2D1A7637C6653C7A1ADE882A530B128	Public Domain	No known copyright restrictions apply.

They represent small-sized individuals. The parasagittal ridges are well-developed and build the limit between the flat dorsal surface of the bones and somewhat concave orbital margins. The parasagittal ridges are very closely located near the midpoint of the bone and form a sandglass shape at the dorsal surface of the bone. The dorsal surface of the bone between the parasagittal ridges is irregular and pierced by small foramina (pineal foramen sensu Villa et al. 2016) and pits (Fig. 9L). Posteriorly, the surface of the frontoparietal table is flat and rather smooth. The irregularities, if present, are weakly pronounced. The parasagittal ridges reach the paroccipital processes posteriorly (Fig. 9I, K). The latter are not fully preserved. Only their bases are observable, which in turn, possess a crest. A smaller posterior median crest is present along the anteroposterior axis of the bone which starts from the posterior margin of the frontoparietal table. The posterior margin of the bone between the median margin and paroccipital process is arched and forms a “bilobed” outline (Fig. 9K). The median crest is lower than the paroccipital processes. Judging from the preserved portions of the paroccipital process and posterior median process, a shorter length of the former in comparison to the latter can be assumed. In ventral view, the frontoparietal incrassation, visible only in HLMD-Ez 2077 (Fig. 9J), representing the posterior portion of the bone, has a round outline with slightly prominent margins. No structure similar to the lanceolate area (sensu Roček et al. 2015) is observable on the available frontoparietals.</p><p>Premaxillae, maxillae, vomer: all three bones are fragmentarily preserved and do not allow any detailed description. The preserved teeth and tooth pedicles display diagnostic characters, such as the conical and slightly lingually bent ankylosed teeth. At the tooth basis, large and deep pits are preserved. The bicuspid tooth has a small labial and large apical cusps (Fig. 9N, O, HLMD-Ez 2084).</p><p>Angulars: in total, two angulars can be clearly assigned to this taxon. They are elongated and curved bones. The coronoid process is compact and can be oval to drop-shape (Fig. 9P, Q). Its surface is concave, rather smooth and can possess tubercles (muscle scars). The Meckelian groove behind the coronoid process is broad and opens dorsally, whereas anteriorly, it is open laterally or slightly dorsolaterally.</p><p>Ilium: The acetabular region of the ilium is robust. The dorsal prominence (sensu Gómez and Turazzini 2015) is not well-developed. The drop-shape dorsal protuberance (sensu Gómez and Turazzinin 2015) is large (Fig. 9R) and can be weakly to moderately developed (Fig. 9V). Its surface is rather smooth, and its small posterior portion is located above the anterior margin of the acetabular crest. The ventral acetabular expansion (also known as pars descendens) does not project ventrally, but it is massive in ventral/dorsal views (Fig. 9R). The dorsal acetabular expansion (also known as pars ascendens), even if only fragmentarily preserved, is moderately developed. The ventral half of the acetabular fossa is massive. The well-developed ventral portion of the acetabular crest projects laterally and contributes to the ventroanterior surface of the acetabular region of the ilia. In larger individuals (e.g. HLMD-Ez 2080), an oval knob-like flat surface is present in the lateroventral cornet between the iliac shaft and acetabulum (Fig. 9V). It represents most probably the attachment surface for the muscle iliacus internus (sensu Gómez and Turazzini 2015). In posterior view, the well-pronounced interiliac groove and laterally projecting acetabular crest are observable. The iliac shaft is moderately developed, lateromedially flattened and has a rather smooth surface.</p><p>Remarks.</p><p>The fossil remains display characteristic features of the genus Palaeobatrachus as well as the family Palaeobatrachidae such as: 1) azygous frontoparietal with a flat dorsal surface; 2) angular coronoid process smooth and/or covered by muscle scars; 3) anteroventrally extending large acetabulum; 4) acetabular area strongly protruding; 5) well-pronounced interiliac groove (Wuttke et al. 2012) and 6) paroccipital processes do not extend probably beyond the level of posterior median process ( Roček et al. 2015; see characters 12, table 2). Among the material available bones, only the frontoparietal can be used for the species-level identification since other elements such as ilium, angular do not contain sufficient diagnostic characters. The Palaeobatrachus frontoparietal from Echzell can be distinguished from other Miocene forms, e.g. P. hiri (locs. Bátraszölos and Sámsonhaza, Venczel 2004), and P. sp. A (loc. Rudabanya, Roček 2005) by the sculptured frontoparietal (vs. unsculptured in P. hiri and P. sp. A) and weakly developed frontoparietal incrassation (vs. strongly developed, in form of crests in P. hiri and P. sp. A). The Echzell frontoparietals strongly resemble the morphology of the P. robustus from the early Miocene (MN2) of France (loc. Laugnac, Hossini and Rage 2000), in having 1) a comparable sculpture on dorsal surface of the bone; 2) the skull table narrows in the midpoint of the bone, giving a sandglass shape; 3) weakly developed, rounded frontoparietal incrassation. We did not compare with P. hauffianus from Randecker Maar, Germany (middle Miocene) ( Roček et al. 2006) which taxonomic status still needs revision.</p></div>	https://treatment.plazi.org/id/46723D41ED3552F993EF2C528E0E5C40	Public Domain	No known copyright restrictions apply.

The tectum supraorbitale is moderately broad. In dorsal view, the lateral superior process is longer than broad. The articulation surface with the squamosal is well-developed, concave and oriented fully laterally (Fig. 7A). Neither incrassation frontoparietalis nor the margins are preserved/observable in the remains. The paroccipital process is reduced, but its dorsal surface possesses a distinct crest. The medial base of the paroccipital process is pierced by the occipital arterial foramen, which is covered dorsally by the posterior margin of the frontoparietal and, thus, not visible in dorsal view (Fig. 7E). The fragmentarily preserved parts of the inferior superior process suggest that it was not longer than the lateral superior process. However, its lateral and slightly ventrally bending can be assumed. The arteria orbitonasalis opens ventrally on the supraorbital tectum (Fig. 7F).</p><p>Squamosals: The dorsal surface is covered by a similar to frontoparietal pit-and-ridge sculpture. The bone remains are fragmentarily preserved. Only in HLMD-Ez 2105 (Fig. 7H, I), an intact posterodorsal process lamina is present, and shows rounded posterior margin. The dorsal and zygomatic processes are broken. However, considering the presence of intact and concave bone margins between the preserved bases of these processes, we can suggest that they were delimited from each other. In ventral view, lamellar structures at the base of the posterolateral processes are observable (Fig. 7I, K). However, they are incomplete for any further description.</p><p>Maxillae: The labial surface of the bone is covered by a dense network of moderately deep to deep pits-and-ridge sculpture. The distinct zygomatic process extends posterodorsally and has a rounded posterior tip (Fig. 5L). The posterior process projects backwards. It is separated clearly from the zygomatic process by a deep concavity and projects much posteriorly. The orbital margin is concave. In lingual view, the pterygoid process projects posteromedially (Fig. 7M, O). Anteriorly, it is connected with the dorsally oriented lamella above the horizontal lamina.</p><p>Premaxilla: In anterior view, the pars dentalis is low but broad. Its surface is covered by rugose structures (Fig. 7P), which recalls the pit-and-ridge sculpture of, e.g., frontoparietal and maxilla. The pars facialis is broken, but its preserved base suggests a L-shaped form. Medially from this process, another shorter and posteromedially oriented process is present. The lateral crest (sensu Venczel 2004) is moderately developed. The dental crest possesses 15 tooth pedicles (Fig. 7Q).</p><p>Vertebrae: three presacral and two sacral vertebrae are present. The vertebra centrum is procoelous (four vertebrae, HLMD-Ez 2098, 2100-2102) or amphicoelous (one vertebra, HLMD-Ez 2099, Fig. 7R). The HLMD-Ez 2099 represents a small-sized individual that, most probably, does not have fully ossified joints. In presacral vertebrae, the neural arch is high; and the neural canal is large. The foramina for the spinal nerve are present slightly above the posterior bases of the neural arch. In presacral vertebrae, they are visible in lateral view, whereas in sacral ones - in posterior views (Fig. 7T). The sacral vertebrae have a broad and flattened transverse process.</p><p>Ilium: Though all ilia are very fragmentarily preserved, the following characters can be observed on the material: the acetabular region triangular; the acetabulum itself has round outline; the dorsal prominence low and covered by rare irregular structures; the dorsal protuberance absent; the moderately deep spiral groove extends from ventrolateral to dorsomedial direction in the region of the fusion of iliac shaft and acetabulum (Fig. 7W -AA); in medial view, the ilioischiatic juncture is covered by elongated striae (Fig. 7Z); the dorsal acetabular expansion larger than the ventral one.</p><p>Remarks.</p><p>The described remains can be assigned to the genus Pelobates based on the following combination of characters: 1) azygous frontoparietals articulating with the squamosals; 2) well-pronounced pit-and-ridge style sculpture with pustular structures on frontoparietal, squamosal and maxillae; 3) the presence of the spinal nerve foramina in vertebrae; 4) the presence of the moderately deep spiral groove on ilium, etc. (e.g., Venczel 2004; Roček et al. 2014). The fossil material of Pelobates can be allocated to the species P. sanchizi considering: 1) the presence of moderately broad tectum supraorbitale; 2) the occipital arterial foramen not visible in dorsal view; 3) the arteria orbitonasalis opening ventrally on the supraorbital tectum; 4) delimited posterior and posterodorsal processes of squamosal (Venczel 2004)</p><p>Comparison of our material with other fossil species of Pelobates ( Böhme et al. 1982; Khozatskiy 1985; Böhme 2010; Roček et al. 2014) allowed to suggest further diagnostic features for P. sanchizi such as: 1) the lateral superior process of the frontoparietal is longer than broad; 2) articulation surface on frontoparieals with squamosal well-developed, concave and oriented fully laterally.</p><p>The single premaxilla from Echzell shows a remarkable feature: ornamented on the anterior surface of the bone, recalling the pit-and-ridge sculpture of, e.g., frontoparietal and squamosal. Comparable ornamentation has not been ever described for the genus Pelobates and in P. sanchizi from other Miocene localities. Only for Eopelobates deani ( Roček et al. 2014), a moderated rugose outer surface has been mentioned.</p></div>	https://treatment.plazi.org/id/38E0BE8B7F1D57B28D83CAC184CF274C	Public Domain	No known copyright restrictions apply.

They are large in size (5-7 mm). In dorsal view, the neural arch is broad and has an outline of a rectangle (HLMD-Ez 2029, Fig. 5A) or square (HLMD-Ez 2031, Fig. 5F). The prezygapophyses have round outlines and project anterolaterally. The neural arch between the prezygapophysese is flat. The neural spine starts behind this short flat surface and posteriorly does not reach the posterior tip of the pterygapophysis. In lateral view, the neural spine is low. It is highest at its middle point. The posterior margin of the pterygapophysis can be bifurcated. Its posterior surface possesses two distinct notches of variable sizes and dimensions. In anterior view, the neural canal is dorsoventrally flattened. In HLMD-Ez 2029, the bases of the prezygapophyses are pierced by the subzygapophyseal (sensu Vasilyan et al. 2017) or anterior (sensu Tissier et al. 2015) foramen. Other vertebrae do not have this character. The arterial canal with large and/or smaller openings runs across the base of the transverse process. The latter is fully preserved only in HLMD-Ez 2029. It projects posterolaterally and is composed of dia- and parapophysis, which are connected with a thin lamina at their medial half (Fig. 5B); otherwise, they are free laterally. Additionally, the parapophysis is connected with the centrum anteriorly and posteriorly by anterior and posterior alar processes, respectively. They build a triangular-shaped lamina (Fig. 5C). In lateral view, a well-pronounced horizontal interzygapophyseal ridge connects the prezygapophysis with diapophysis, whereas the horizontal dorsal lamina connects the diapophysis with postzygapophysis. The centrum is flattened dorsoventrally and arched.</p><p>Remark.</p><p>The general morphology and large size of remains, including the dorsoventrally compressed ophistocoelous vertebrae, broad and low neural arch as well as arched vertebra centrum allow assigning the remains to the genus Salamandra (Estes and Hoffstetter 1976). HLMD-Ez 2029 shows a slightly different morphology (presence of subprezygaphyseal foramen vs. its lack; square outline of the vertebra in dorsal view vs. rectangular outline) than the other available vertebrate. Comparable morphology is observable in the second vertebrae of Salamandra salamandra (see the morphosource link https://www.morphosource.org/concern/parent/000S44906/media/000165871). Thus, the HLMD-Ez 2029 can interpreted as an anterior vertebra.</p><p>Chelotriton Pomel, 1853</p></div>	https://treatment.plazi.org/id/E98A52C3962F59E4A46D5DFC409A03D6	Public Domain	No known copyright restrictions apply.

Because the parietal UMJGP 204.749 (Fig. 13A, B) is better preserved than HLMD-Ez 1965 (Fig. 13C, F), it has been designated as the holotype for the new taxon.</p><p>Diagnosis.</p><p>Anguine lizard distinguishable from Anguis, Pseudopus and Ophisaurus by two autapomorphic features:</p><p>the parietal table gradually expands laterally in the anterior direction in an extreme way; thus, it appears to be distinctly constricted at the level of the parietal foramen or slightly posterior to it. The lateral margins of the table markedly diverge anterolaterally from this point, inclining at an angle of about 30° from the median plane. Posteriorly located lateral margins diverge gradually posterolaterally and continue to more-or-less straight supratemporal processes. Due to the lateral expansion of the parietal table, the anterolateral corner of the parietal table reaches further laterally than the supratemporal process. The ornamented surface on the dorsal side of the bone gradually widens anteriorly as well (in contrast to being rectangular);</p><p>the parietal cranial crests diverge in the anterior direction to form a V that separates the cranial vault from the muscular surface laterally (the anteriormost section of the crests bents laterally rather than medially).</p><p>Besides these two autapomorphic features, this taxon is characterized by the unique combination of the following characters: (1) the occipital shield is large, its anteroposterior length is longer than the length of the posteriorly located smooth area; (2) a narrow muscular surface is present; (3) a short postfoveal crest is present; (4) anterior end of the ventrolateral ridge of the supratemporal process joins the parietal cranial crest at the level anterior to the posteromedial margin of the floor of the parietal fossa. The parietal crest is sharp in the area of the junction; (5) the virtual line, continuing from the ventrolateral ridge of the supratemporal process to the anterior margin of the parietal table, reaches the level as the lateral margin of the parietal foramen here; (6) the supratemporal process has a smooth ventrolateral surface, which fluently continues anteriorly to the muscular surface of the parietal table; and (7) the supratemporal process is straight.</p><p>Description.</p><p>Parietal: The parietal UMJGP 204.749 (Fig. 13A, B) from Gratkorn is fairly preserved, whereas HLMD-Ez 1965 (Fig. 13C, D) from Echzell represents the posterior half of the parietal table, with the left supratemporal process being, however, only partly preserved. The description is therefore based mostly on the holotype UMJGP 204.749. The ornamented surface of several fused headshield osteoderms covers most of the parietal table. The ornamentation consists of well-developed foramina and pits of various sizes, being densely distributed. At the periphery of the ornamented surface, radiated grooves and ridges are developed. The interparietal shield is well recognized in both specimens. This region is pierced by the large anteroposteriorly elongated parietal foramen. Unfortunately, its anterior margin is not preserved. The occipital shield is very large. Its anteroposterior length is twice as long as the length of the posteriorly located smooth area. The parietal notch is well developed. The lateral (=parietal) shields are preserved (but note that the almost entire lateral margins of the parietal table in HLMD-Ez 1965 are damaged). The arcuate edge runs on the dorsal surface of the bases of the supratemporal processes and diminishes laterally. The right supratemporal process is almost completely preserved, being straight. The parietal table extremely widens anteriorly - so it appears to be distinctly constricted at the level of the parietal foramen or slightly posterior to it. Thus, the lateral margins of the table markedly diverge anterolaterally from this point, inclining at an angle of about 30° from the median plane. Due to the lateral expansion of the parietal table, the anterolateral corner of the parietal table reaches further laterally than the supratemporal process. The anterolateral corners protrude into anterolateral processes. The ornamented surface is not rectangular but gradually widens anteriorly as well. The anterior end of the interparietal sulcus lies medial to the anterolateral corner of the ornamented surface.</p><p>On the ventral surface, many diagnostic features can be recognized. The oval parietal fossa is small, located in the central posteriormost region of the parietal table. The short postfoveal crests are well developed. In ventral view, both cranial crests are preserved, especially the complete right one, including the anterior portions missing in the Echzell specimen. The cranial crests are sharp. They diverge anteriorly, forming a V-shaped outline that separates the cranial vault from the muscular surface laterally. The muscular surface is narrow, but present. The virtual line, continuing from the ventrolateral ridge of the supratemporal process to the anterior margin of the parietal table, reaches the level as the lateral margin of the parietal foramen here. The ventrolateral ridge of the supratemporal process is well developed and preserved on the right side in UMJGP 204.749 and left side in HLMD-Ez 1965. Its anterior end joins the parietal cranial crest at the level anterior to the posteromedial margin of the parietal fossa. The cranial crest is sharp in this region. The root portion of the supratemporal process is broad. The other distal portion distinctly narrows posteriorly. The ventrolateral ridge is well developed. The supratemporal articulation extends anteriorly, being well visible on the lateral surface of the supratemporal process. Anteriorly to it, between the most anterior portion of the ventrolateral ridge and the anterolateral margin of the supratemporal process, a short ventrolateral surface can be recognized. This surface lies posterior to the parietal cranial crest-supratemporal process junction (note that it is broadly damaged in the Echzell specimen).</p><p>Remarks.</p><p>See the discussion part.</p><p>Phylogenetic analysis of Smithosaurus echzellensis .</p><p>The phylogenetic trees presented here are based on limited fossil material - the parietal, and thus more complete fossil specimens of this taxon are needed to draw more robust conclusions. However, in both two analyses, Smithosaurus echzellensis is consistently recovered as the sister taxon to either [ Ophisauriscus quadrupes + Ophisaurus holeci] + [ Anguis + Ophisaurus] (in the first analysis) or [ Anguis + Ophisaurus] (in the second analysis). In overall, the support for the clade is very low (no strict synapomorphy; the calculating Bremer supports collapsed the node into polytomy, see below) and thus, the interpretation of the Smithosaurus relationship among anguines needs to be met with caution.</p><p>A New Technology (NT) search in TNT produced a single tree (Fig. 14A). The position of Smithosaurus echzellensis is recovered as being sister to the clade [[ Ophisauriscus quadrupes + Ophisaurus holeci] + [ Anguis + Ophisaurus (all others except of O. holeci)]]. The calculating Bremer supports collapsed the node (Bremer value 1, relative Bremer 25; Fig. 14B), with the relationship among Smithosaurus echzellensis and the clades [ Ophisauriscus quadrupes + Ophisaurus holeci] (Bremer value 3, relative Bremer 50) and [ Anguis + Ophisaurus] (Bremer 2, relative Bremer 50) being unresolved.</p><p>The heuristic search in TNT produced two equally parsimonious trees. In both, Smithosaurus echzellensis is recovered as sister to [ Anguis + Ophisaurus (all others except of O. holeci)], whereas Ophisauriscus quadrupes and Ophisaurus holeci are sister to the clade formed by Smithosaurus, Anguis and Ophisaurus (all others except of O. holeci). This is contrary to the results from the NT analysis (see above). In the strict consensus tree, however, the position of Smithosaurus is unresolved among [ Ophisauriscus quadrupes + Ophisaurus holeci] and [ Anguis + Ophisaurus (all others except of O. holeci)], although all these taxa together form a clade. Thus, the topology of examined taxa in this strict consensus tree is identical to that figured in Fig. 14B.</p></div>	https://treatment.plazi.org/id/18CE628A273956928FE5881DC6263025	Public Domain	No known copyright restrictions apply.

Both pre- and postzygapophyses are small; thus, there is a typical tendency toward the elongation of the centra in caudal vertebrae and a relative reduction of all processes. The cotyle and condyle are dorsoventrally depressed. The neural canal is a tunnel-like structure here. The haemapophyses are fused to the posterior portion of the centrum, but, unfortunately, their ends are broken off. Only the bases of the anteroventrally oriented transverse processes (pleurapophyses) are preserved, being dorsoventrally slightly flattened. They are pierced by a foramen. The distal portions are, however, broken off. The neural spine is posterodorsally oriented, rather slim and pointed. The transverse autotomic split is present.</p><p>Remarks.</p><p>The presence of an autotomic split indicates that we can exclude Pseudopus, in which only autotomic foramina are developed (see Čerňanský et al. 2019). In contrast, the autotomic split is present in both Anguis and Ophisaurus (see Hoffstetter and Gasc 1969).</p><p>Osteoderm: A large number of osteoderms of several types are preserved in the material. The first type represents wide, rectangular osteoderms (e.g., HLMD-Ez 1985, Fig. 16G-F). There is a low medial ridge running along their central regions. However, the ridge is almost indistinctive and restricted only to the sculptured region. The anterior overlap surface is large and occupies about one-third of the external surface. The lateral bevel is the highest close to the overlap surface. The posterior portion of the external surface is ornamented. The ornamentation is formed by several tubercles, pits, long grooves, and ridges diverging from the central region. Three foramina pierce the central part of the internal surface. The second type (and the most common, as represented by HLMD-Ez 1986, Fig. 16H) includes slender osteoderms. In those, the medial ridge runs along the entire external surface, including both ornamented and anterior overlap surface. The third type (rare, HLMD-Ez 1987, Fig. 16I) is represented by a flat and wide osteoderm without a medial ridge.</p><p>The differences might very likely represent individual variability and a different body topology from where osteoderms originated (e.g., ventral vs. dorsal armour; see, e.g., Čerňanský and Klembara 2017). Their determination to the alpha taxonomy level is currently impossible. Nevertheless, they resemble osteoderms of Ophisaurus, but other taxa cannot be excluded.</p></div>	https://treatment.plazi.org/id/FF69E9F7FD8C51E4A2EEB13293164477	Public Domain	No known copyright restrictions apply.
