M a t e r i a l: 40 planispiral specimens, 8 specimens forming glomerulate knots, 74 tube fragments. S u b s t r a t e: One small tube is attached to a valve of the oyster Amphidonte (Amphidonte) reticulatum (REUSS, 1846), another specimen to an Ostrea sp., and a third one to a pectinid valve. D e s c r i p t i o n. The tube is coiled to form either glomerulate knots or planispirals. The surface of the tube is smooth without any ornamentation. The tube diameter ranges from 1 to 2.7 mm, usually from 1.3 to 2.2 mm, and in most specimens it measures circa 2 mm. The cross-section of the tube as well as the cross-section of the lumen is circular. R e m a r k s a n d r e l a t i o n s h i p s. The genus Glomerula ranges from at least the Hettangian to the Recent, and it is common and geographically widespread from the Late Toarcian until the Eocene. Possible Triassic or even Late Palaeozoic representatives of Glomerula are mentioned by Ippolitov et al. (2014). Glomerula serpentina is often a common species in rocky coast facies of the Cretaceous period. As discussed by Jäger (2005) and Sklenář et al. (2013), distinguishing species of Glomerula is problematic, due to the simple morphology of the tubes which display only a limited number of morphological features and the large variability even within one sample, therefore the schemes presented in previous papers are certainly in part artificial. The occassional presence of trilobate lumina can be used as a feature for taxonomic discrimination between a set of Cretaceous Glomerula species from a more ancient set of Jurassic Glomerula species (Jäger 2005) which totally lack trilobate lumina. However, a trilobate lumen was not observed by us in thespecimens from Předboj. Within the set of Cretaceous Glomerula species, the usually relative large and usually solitary G. serpentina is the most common. Clusters composed of dozens or even more than a hundred Glomerula tubes occurring mainly in the Santonian and Campanian of South Sweden, North Germany, and England (type area) may be separated taxonomically and determined as G. plexus (J. DE C. SOWERBY, 1829). Only in fine-grained offshore facies it has proven useful to separate specimens with a small tube diameter as Glomerula lombricus (DEFRANCE, 1827).	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

M a t e r i a l: One specimen. S u b s t r a t e: No substrate is preserved. D e s c r i p t i o n. The tube is 7 mm long. The tube diameter is 1.8 mm at the posterior trapezoidal cross-section and 1.2 mm at the aperture. The upper side of the tube bears three cocks‘ comb-like longitudinal ridges. The lumen is circular. R e m a r k s a n d r e l a t i o n s h i p s. Filogranula cincta resembles three Late Cretaceous species: Vermiliopsis fluctuata (J. DE C. SOWERBY, 1829), Metavermilia (Vepreculina) fimbriata REGENHARDT, 1961 and Serpula? trilineata ROEMER, 1841. Vermiliopsis fluctuata has an extra two longitudinal ridges and is heptangular in cross-section, its aperture does not show any strong tendency to grow upwards. The latter is also true for Serpula? trilineata which erroneously was affiliated to the genus Janita SAINT-JOSEPH, 1894 by Jäger (1983). Moreover, Serpula? trilineata has weaker longitudinal ridges and delicate transverse ornamentation. Metavermilia (Vepreculina) fimbriata, of which only the free tube portion is known, has a smaller tube diameter of only 0.7 – 1.0 mm, and a variable number of often granulose longitudinal ridges which occur all around the tube.	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

131A878FFFC8037095D0EB969AF6212F.taxon	description	S u b s t r a t e: No substrate is preserved, but vice versa one of the tubes (Pl. 3, Fig. 3) is encrusted by membranipore bryozoa. D e s c r i p t i o n. The tube is circular in cross-section and measures 3 – 9 mm in diameter. An annular peristome, characteristic of Neovermilia ampullacea, is present. R e m a r k s a n d r e l a t i o n s h i p s. The genus Neovermilia first occurred in the Late Oxfordian (Radwańska, 1996). Neovermilia is common in the coarse-grained rocky coast facies sites in the BCB, e. g. Velim, Kamajka near Chotusice, Kaňk – Na Vrších, etc. Tube morphology is quite variable, making a useful discrimination between species nearly impossible. Some specimens bear a sharp longitudinal keel, whereas other specimens have no keel but a tube with a circular cross-section. Many specimens of the genus Neovermilia possess hollow “ tubulae ” (two small longitudinal canals near the borders of the tube’s base; compare e. g. Thomas 1940, Hedley 1958, fig. 9, Jäger 1983, fig. 2, Vinn and Wilson 2010, fig. 4, Sklenář et al. 2013, Ippolitov et al. 2014). In the genus Neovermilia, the tubulae are cellular and composed of shorter cells than in the genera Spirobranchus BLAINVILLE, 1818 and Pyrgopolon DE MONTFORT, 1808. Formerly, Neovermilia ampullacea had been attributed to the genus Proliserpula REGENHARDT, 1961, but according to Jäger (2005) Proliserpula is a subjective synonym for Neovermilia. The shape and structure of the tube in the Plio-Pleistocene to Recent species Neovermilia falcigera (ROULE, 1898) (see Zibrowius and ten Hove 1987, fig. 2) is very similar to that of the Cretaceous specimens except that N. falcigera has no keel, weaker transverse ornamentation and a thick tube wall. However, a strong keel and delicate transverse ornamentation are present in another Recent Neovermilia species, N. globula (DEW, 1959). The fossil genus Propomatoceros WARE, 1975 is usually triangular or rounded triangular in cross-section. Although some specimens of Neovermilia are also triangular in cross-section, this genus is usually more rounded with tunnel-shaped or circular cross-sections. Ziegler (1974, 1984) described the present species from many nearshore localities of the Late Cenomanian to the Middle Turonian of the BCB, whereas specimens of N. ampullacea sensu stricto from the offshore locality Úpohlavy were described and discussed by Sklenář et al. (2013).	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

131A878FFFCF037696F4EB28989C24C2.taxon	description	M a t e r i a l: Three complete specimens, one damaged coil and four fragments. S u b s t r a t e: In the figured specimen, a small tube is attached to a larger tube of the same species. D e s c r i p t i o n. The attached posterior tube portion forms a coil, whereas the free anterior tube portion is elevated and slightly spindle-shaped. In a well preserved specimen which has a spine over the aperture, the attached coil measures 6.4 mm in diameter, and the free anterior portion reaches a tube diameter of 3.9 mm. Longitudinal ornamentation consists of distinct lines on the upper side resembling tiny grooves. Transverse ornamentation consists of strong annular peristomes and distinct V-shaped wrinkles forming a spine over the aperture in one specimen, whereas in two other specimens such a spine is not present. Quadrangular cross-section. R e m a r k s a n d r e l a t i o n s h i p s. It may be speculated if the one specimen with a spine over the aperture and the two specimens lacking such a spine may belong to two different species, L. reussi and L. plana LOMMERZHEIM, 1979, respectively. However, the more likely explanation is that the spines may have simply broken off. This alternative explanation is supported by the fact that in a detailed revision and description of this species from other rocky coast facies localities of the BCB which will be published by Jäger et al. (in prep.), all well preserved apertures usually bear spines. The angular tube morphology bearing spines at the aperture somewhat resembles that of the genus Placostegus PHILIPPI, 1844, however, typical representatives of Placostegus are smaller and have a translucent tube.	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

131A878FFFCE0375958FEC359B4027EC.taxon	description	M a t e r i a l: Six complete or nearly complete tubes, one damaged coil, two juvenile tubes and two fragments. S u b s t r a t e: Two tubes are attached to oyster valves. Two other tubes are attached to dorsal valves of the brachiopod Phaseolina phaseolina (VALENCIENNES in LAMARCK, 1819). Three tubes are attached to, and one of these is coiled around, separate tubes of Placostegus rigidus. Another specimen had originally been attached to an unknown substrate which is no longer present, maybe a crinoid stem or a stem of an alga. A small circular tube, maybe the additional tube characteristic for the genus Dorsoserpula (“ Nebenröhre ”; see Jäger 1983, p. 39), a juvenile serpulid tube or an overgrown stem of an alga, is laterally attached to the anterior portion of this specimen. D e s c r i p t i o n. Usually the tube is almost planispirally coiled and consists of two to three whorls. However, a few tubes, especially in the posterior tube portion, are nearly straight or curved or low trochospiral. Tube diameter ranges from 0.9 to 2.5 mm, and coil diameter ranges from 2.7 to 5.5 mm. There is a delicate but sharp and distinct keel which may be slightly undulating on top of the tube, respectively at the periphery of the coil, and some of the larger tubes possess two additional but less distinct lateral keels which start only in the posterior part of the coil, but don’t extend to the aperture of the tube. A smaller specimen has only one lateral keel. Apart from the keels, the surfaces of most tubes appear to be relatively smooth, but under the microscope very delicate, almost indistinct transverse wrinkles are visible. In one specimen, transverse ornamentation is curved forward, similar to the letter “ V ” turned upside down. The cross-section of the tube and the lumen are circular. R e m a r k s a n d r e l a t i o n s h i p s. Jäger (2005) previously considered D. gamigensis (GEINITZ, 1875) a junior subjective synonym of D. bipartita, but, however, did not decide if these Late Cenomanian to Early Turonian forms should be synonymized or not with D. wegneri (JÄGER, 1983) which is wide-spread mainly in the younger portion of the Late Cretaceous. After studying specimens from the BCB, Jäger (2014) concluded that D. bipartita and D. wegneri were two closely related but separate species, differing by size (D. bipartita remains smaller), by the rarity (but not total absence!) of a keel in subspecies D. wegneri wegneri, whereas D. bipartita usually (but not in every specimen!) has a keel, and by geological age (D. wegneri wegneri is now considered to exist only from the Middle Turonian onwards). Some specimens from Předboj earlier (Kočí 2012 b) determined as Dorsoserpula wegneri are affiliated to D. bipartita here due to their small size, presence of a keel and relatively old geological age. After a long gap in geological time, keeled forms became common again in the Maastrichtian and were considered by Jäger (2005) to be a separate subspecies, D. wegneri maastrichtensis JÄGER, 2005, differing from D. bipartita mainly by possession of cellular tubulae.	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

S u b s t r a t e: One specimen is attached to an oyster valve Ostrea sp., another specimen is attached to a bryozoan stem. Vice versa, three Placostegus tubes are used as substrates, each of them by a Dorsoserpula bipartita tube. D e s c r i p t i o n. The posterior tube portion attached to the substrate is straight or coiled to form a loop, the anterior free tube portion is long and rises steeply. One sharp, sometimes undulating keel is present in the posterior tube portion, three sharp keels in the free tube portion, forming three spines surrounding the aperture of the free tube portion. Between the keels a narrow longitudinal furrow may be present. Apart from the keels and furrows, the surface of the tube appears to be smooth at first sight, but under the microscope very fine distinct transverse corrugations are visible. Cross-section of the tube triangular, subtriangular or, less typical, square. R e m a r k s a n d r e l a t i o n s h i p s. The tube of Placostegus velimensis JÄGER et KOČÍ, 2007 is similar in shape, but the present species has a narrower tube diameter, less developed transverse ornamentation, and most tubes are triangular to subtriangular instead of square in cross-section.

Specimen number NM-O 5388 has many borings produced by unknown marine organisms. Its attached portion is triangular in cross-section, and the free portion is circular. The specimen of P. zbyslavus NM-O 5390 from Zbyslav no. 51 bears transverse ornamentation and has a triangular cross-section. In addition to these specimens figured by Ziegler (1984), there are some other specimens belonging to P. zbyslavus which were not figured in Ziegler (1984) but, nevertheless, are kept in the collection of his original specimens in the NM Prague. A tube of the present species from Velim-Skalka bears inventory number NM-O 5172, the same number had erroneously been mentioned by Ziegler (1984, p. 236) as the number of the holotype of this species, although the figure number 1 is correct (in spite of the wrong plate number, 5 instead of 6) and the correct type locality Zbyslav no. 51 indicate specimen no. NM-O 5390 figured on pl. 6, fig. 1 to be the correct holotype. Another unfigured specimen of the present species from Velim has inventory number NM-O 5389 which is presumably the correct number, even though Ziegler (1984, p. 253) had erroneously mentioned this number in the figure caption of his so-called “ Eoplacostegus sulcatus (SOWERBY, 1829) ” from Velim which represents, however, a fine specimen of Laqueoserpula reussi with a rounded quadrangular cross-section and whose correct number, according to the label, is NM-O 5167.	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

M a t e r i a l: At least four specimens. Two incomplete specimens representing the anterior tube portion with the aperture preserved, one of them with remains of the transitional area between the attached and the free portion. S u b s t r a t e: Not preserved. One of the tubes is infested by the symbiont Protulophila gestroi ROVERETO, 1901. D e s c r i p t i o n. A medium-sized Pyrgopolon. The free tube portion is straight and measures 2.9 mm, respectively 3.4 mm in diameter which stays nearly constant throughout the whole free tube portion. The upper side of the tube bears three strong straight keels of which the median keel is the strongest and highest. In the lower left and right there are two more keels but these are wide and very rounded, in cross-section appearing like lobes. Faint incremental lines protrude slightly on the median keel and cause this keel to protrude a little over the aperture. Apart from the keels and the faint incremental lines, the tube’s surface appears to be relatively smooth. The lumen is circular. The colour is usually brownish. R e m a r k s a n d r e l a t i o n s h i p s. The tubes from Předboj differ considerably from Pyrgopolon (P. or Triditrupa) tricostata sensu stricto from the Middle Cenomanian of Essen in which the tube diameter increases rapidly in size, it has three wide rounded keels situated at almost equal distances from each other all around the tube, and its circular inner tube wall is visible from the posterior tube fracture. This latter factor is typical for nearly all subgenera of the genus Pyrgopolon except for the subgenus Pyrgopolon (Septenaria) REGENHARDT, 1961, see Jäger (2005). Thus, the tubes from Předboj may even belong to a different subgenus than tricostata sensu stricto. Moreover, the tubes from Předboj also differ from tubes from Saxony described by Jäger (2014) as “ Pyrgopolon (Septenaria) sp. aff. tricostata ” in which the keels, in spite of considerable variation, are more similar to those of tricostata sensu stricto. Within the BCB, except for its Saxon portion, the tubes from Předboj represent a similar fauna as the tubes described by Kočí (2009 a, b, 2010, 2012 a) from other rocky coast facies localities (Kaňk, Velim, Nová Ves near Kolín, Chrtníky, Kamajka) which display a wider range of tube diameters. For a more detailed discussion see Kočí (2012 a). The two specimens described and figured by Ziegler (1984) as “ Ditrupa tricostata (GOLDFUSS), 1841 ” may, in spite of some morphological differences, represent the same species as the Předboj tubes. One of these specimens (NM-O 5394) possesses a “ Favosites structure ” at the transition from the attached to the free tube portion; as a consequence at least this specimen belongs to the subgenus Pyrgopolon (Septenaria). Moreover, in the collection of Ziegler’s original specimens kept in the National Museum in Prague, there is another but unfigured specimen of P. cf. tricostata labelled with inventory number NM-O 5363 instead of the missing “ Ditrupa subtorquata ” specimen with the same registration number figured by Ziegler (1984, pl. 6, fig. 7).	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

D i a g n o s i s: A medium-sized species of the subgenus Pyrgopolon (Septenaria). Attached tube portion bears five distinct keels of which the median keel is very strong and undulating, whereas the other four keels are weaker and straight. Free tube portion bears seven moderately to weakly developed keels giving the tube a near-circular subheptagonal cross-section. E t y m o l o g y: In honour of Dr. Olga Nekvasilová, CSc.

T y p e h o r i z o n: Upper Cenomanian. M a t e r i a l: Three well preserved tubes. S u b s t r a t e: One of the tubes is attached to an oyster valve. D e s c r i p t i o n. The attached tube portion is slightly to strongly curved posteriorly and straight anteriorly, the short straight free anterior tube portion rises moderately above the substrate. For keels and cross-section see diagnosis. Anterior tube portion bears transverse ornamentation consisting of indistinct weak corrugations. R e m a r k s a n d r e l a t i o n s h i p s. Pyrgopolon (Septenaria) zitti (see below) is similar, but differs by possessing only three keels situated closer together in the attached tube portion.	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

D i a g n o s i s: A moderately large-sized species of the subgenus Pyrgopolon (Septenaria). Attached tube portion has three keels close to each other; the median keel appears as a high and sometimes undulating comb, the other two keels are straight and much smaller. One or two additional rounded longitudinal edges may or may not be present on the latera. No transverse ornamentation. Cross-section triangular. E t y m o l o g y: In honour of Dr. Jiří Žítt, CSc. (the famous Czech specialist in Mesozoic echinoids, asteroids and crinoids) who studied the geology and paleontology of the Předboj site and other rocky coast localities in the BCB. H o l o t y p e: The specimen is deposited in the collections of the National Museum in Prague, inventory number NM-O 7555, and figured on Pl. 2, Fig. 1, as the holotype. The specimens with inventory numbers NM-O 7556, O 7557, O 7558 and O 7571 and figured on Pl. 2, Fig. 2, 3, 4 and Pl. 3, Fig. 5 are paratypes. T y p e l o c a l i t y: Předboj near Prague. T y p e h o r i z o n: Upper Cenomanian. M a t e r i a l: At least four specimens representing at least 16 tubes, maybe more. S u b s t r a t e: Four tubes are attached to an oyster valve, eight tubes are attached to a Spondylus valve and in part to each other (Pl. 3, Fig. 5), two specimens (Pl. 2, Fig. 3 – 4) each consist of two tubes of which the upper one is attached to the lower one. D e s c r i p t i o n. Tube moderately large in size. The attached tube portion has three keels situated close to each other; the median keel is developed as a high and, in some tubes, undulating comb, whereas the other two keels are straight and much smaller, but nevertheless distinct. In a few tubes, one or two additional rounded longitudinal ridges may be present on the latera. Otherwise the surface is rather smooth; no transverse ornamentation. Tube triangular in cross-section; lumen circular. One or two specimens, including one of the two tubes shown in Pl. 2, Fig. 4, possess a distinct “ Favosites structure ”. However, the other tube shown in Pl. 2, Fig. 4 shows in cross-section depressions at the lateral areas of the base which may be interpreted as tubulae. Tube colour is bright yellow, slightly brighter than in Pyrgopolon gen. et sp. indet. R e m a r k s a n d r e l a t i o n s h i p s. The welldeveloped keels and the lack of peristomes point to the genus Pyrgopolon, and the presence of a distinct “ Favosites structure ” (Jäger 1983, Jäger and Breton 2002) characteristic for Pyrgopolon (Septenaria) clearly proves affiliation to this subgenus. However the triangular cross-section resembles that of the genera Propomatoceros, Spirobranchus and some fossil specimens of Neovermilia, all of these lacking a “ Favosites structure ”. One of the two tubes in Pl. 2, Fig. 4 shows structures which may be tubulae which are known in the above mentioned genera Propomatoceros, Spirobranchus, Neovermilia and others and in the subgenus Pyrgopolon (Pyrgopolon), but not in the subgenus Pyrgopolon (Septenaria), making determination of this specimen doubtful, even though its well-developed keels clearly match those of Pyrgopolon (Septenaria) zitti.	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.

S u b s t r a t e: The tubes had previously been attached to an unknown substrate. D e s c r i p t i o n. Tube large, 5.5 – 7.4 mm wide (measured at the base) and 5.8 – 6.0 mm high at the aperture respectively at the anterior cross-section; length reaching more than 25 mm in the longest preserved fragment. Attached posterior portion slightly twisted to strongly curved, free anterior portion unknown if at all existing. The attached portion in some specimens bears three keels or rounded edges, in other specimens five, most of them are inconspicuous except for the very broad flat median keel which shows a distinct chevron-like or V-like pattern of strongly protruding incremental lines. Cross-section rounded triangular posteriorly but tunnel-shaped or rounded trapezoid anteriorly. Lumen circular. Tube wall thick, with a thin innermost tube layer which is slightly separated from the main tube layer. R e m a r k s a n d r e l a t i o n s h i p s. In the Late Cretaceous of Europe the vast majority of Pyrgopolon specimens belong to one of two subgenera, P. (Pyrgopolon) and P. (Septenaria), which may look more or less similar in outer aspect but are usually well distinguishable by several features of the tube structure: usually P. (Pyrgopolon) has a moderate to thin tube wall and well-developed chambered tubulae in the lateral areas of the attached tube base, and often its inner tube layer is more or less separated from the outer tube layer during diagenesis. In contrast, P. (Septenaria) has a moderate to thick tube wall, which in the lower half of the attached portion may show “ Favosites structure ” which is a cellular structure resembling that of the Paleozoic coral genus, and some specimens may show a honeycomb-like ornamentation on the surface of the tube. The problem with the present species is that it combines features of both previously mentioned subgenera, and plus the low number of available specimens mean it is therefore impossible to affiliate it to any subgenus at the present state of knowledge. Features pointing to P. (Pyrgopolon) are a thin innermost tube layer which is slightly separated from the main tube layer and the nondevelopment of a “ Favosites structure ” (Jäger 1983, Jäger and Breton 2002) and honeycomb-like ornamentation. Features pointing to P. (Septenaria) are the thick tube wall and the absence of tubulae. In its relatively large size and thick tube wall, the present species resembles Pyrgopolon (Septenaria) sp. B (Kočí 2010) which, however, has a thicker external tube layer and developed cellular layers.	en	Kočí, Tomáš, Jäger, Manfred (2015): Sabellid And Serpulid Worms (Polychaeta, Canalipalpata, Sabellida, Sabellidae, Serpulidae) From The Rocky Coast Facies (Late Cenomanian) At Předboj Near Prague.
