773587F6FFEC4910FF1E0695D5E5AD1C.taxon	etymology	Etymology. The generic name (long-legged aetosaur form) is derived from the Greek word aetobarbakina (longlegged buzzard, vulgar name of the falconiform Buteo rufinus) and the Latin word oides (form); in allusion to the elongated humerus and tibia in relation to the axial skeleton and the Greek word aetos (eagle), which refers to the name Aetosaurus (eagle reptile). The specific name is derived from the country Brazil from which the holotype specimen was discovered.	en	Desojo, Julia B., Ezcurra, Martín D., Kischlat, Edio E.

773587F6FFEC4910FF1E0695D5E5AD1C.taxon	diagnosis	Diagnosis. Medium-sized aetosaur (around 2 meters in total length) distinct from other archosaurs by the following combination of characters (autapomorphies indicated by an asterisk): cervical vertebrae with prezygapophyses widely laterally extended through most of the anterior edge of the diapophysis * and with hyposphene; midcervical vertebrae with anterior articular facet width more than 1.2 times wider than the posterior one * and without ventral keel; anterior and mid-dorsal vertebrae without lateral fossa in the centrum, and postzygapophyses mainly posteriorly projected; anterior caudal vertebrae with extremely anteroposteriorly short prezygapophyses *; elongated humerus and tibia in relation to axial skeleton (including humerus with a length / transverse width at midlength ratio greater than 12) *. The paramedian osteoderms of Aetobarbakinoides present a radial ornamentation composed of grooves and pits and with a weakly raised anterior bar. This osteoderm morphology is also exhibited by Paratypothorax and Rioarribasuchus, but Aetobarbakinoides differs from these taxa in the presence of proportionally transversely narrower and strongly ventrally flexed paramedian osteoderms. Locality and horizon. Inhamandá, close to the city of Sao Pedro do Sul, center of the Rio Grande do Sul State, southern Brazil (Fig. 1). Sequence 2 of the Santa Maria Supersequence (Hyperodapedon Assemblage Zone) (late Carnian-earliest Norian, 231.4 - 225.9 Mya, Late Triassic; Langer et al. 2007; Martinez et al. 2011) (Fig. 2). Biostratigraphical setting. The predominant lithofacies at the Inhamandá 1 locality is non-laminated to finely laminated reddish mudstones, with some sandy inclusions (Zerfass et al. 2003). From this locality were also collected the rhynchosaurs Hyperodapedon huenei and Hyperodapedon mariensis and the holotype of “ Aetosauroides subsulcatus ” (MCP 13 a-b-PV: currently considered a junior synonym of Aetosauroides scagliai; Desojo and Ezcurra 2011) (Langer et al. 2007). The Inhamandá 1 locality is situated in the Acme Zone of the Hyperodapedon Assemblage Zone, which was correlated with the lower levels of the Argentinean Ischigualasto Formation of late Carnian-early Norian age (Langer et al. 2007). The Santa Maria Hyperodapedon Acme Zone also contains the following known species: the rhynchosaurs Hyperodapedon sanjuanensis and Hyperodapedon sp., the proterochampsid Rhadinosuchus gracilis, the pseudosuchians Aetosauroides scagliai and Rauisuchus tiradentes, the cynodonts Therioherpeton cargnini, Prozostrodon brasiliensis, and Gomphodontosuchus brasiliensis, the parareptile Candelaria barbouri, the dinosaurs Staurikosaurus pricei, “ Teyuwasu barberenai ”, and Saturnalia tupiniquim (Langer 2005; Langer et al., 2007; Desojo and Ezcurra, 2011). A recent study on the chronostratigraphy of the Ischigualasto Formation indicates that the rhynchosaur biozone (Scaphonyx - Exaeretodon - Herrerasaurus biozone) and the younger Exaeretodon biozone (in which Hyperodapedon and Herrerasaurus are not recorded) can be constrained between 231.4 and 225.9 Ma (Martinez et al. 2011). The age of the boundary between both biozones of the Ischigualasto Formation cannot be confidently assessed. In the Santa Maria 2 Sequence most localities have Hyperodapedon - Exaeretodon associations and in the cases in which a locality only possesses Exaeretodon (e. g. the Sacisaurus site; Langer et al. 2007) we cannot assign it unambiguously to the Exaeretodon biozone because the assessment will be based on negative evidence. Accordingly, we have decided to consider here that the entire Hyperodapedon Assemblage Zone is constrained between the 231.4 and 225.9 Ma (Fig. 2).	en	Desojo, Julia B., Ezcurra, Martín D., Kischlat, Edio E.

773587F6FFEC4910FF1E0695D5E5AD1C.taxon	description	Description. The length of the preserved dorsal centra of Aetobarbakinoides is very similar to those of the holotype of Aetosauroides (PVL 2073) and a statistical analysis does not recover a significant difference between the size of both specimens (p <0.05) (see below). Accordingly, we estimate that Aetobarbakinoides had a similar body size to that of PVL 2073, with a total length of 2 meters (Desojo & Ezcurra 2011). The absence of open neurocentral sutures in the available vertebrae suggests that CPE 2 168 was not a juvenile individual at the time of death of the animal (Irmis 2007).

Cervical vertebrae. Two cervical vertebrae are preserved in the holotype of Aetobarbakinoides (Figs. 3, 4). A mid-cervical probably corresponds to the fifth or sixth vertebra of the series based on the position of the parapophyses, which are positioned slightly below the mid-height of the vertebral centrum. This vertebra is amphicoelous and the length of the centrum is slightly lower than the height of the anterior articular facet, with a ratio of 0.97 between them. This ratio resembles those of the mid-cervical vertebrae of most aetosaurs, including Typothorax (C 6: 0.74: Long & Murry 1995: fig. 102 a), Stagonolepis robertsoni (C 6?: 0.84, Walker 1961: fig. 7 g), Sierritasuchus (anterior or mid-cervical: 0.93, Parker et al. 2008: fig. 2 f), and Desmatosuchus spurensis (C 5: 0.93; Parker 2003; 2008). In Neoaetosauroides this ratio (C 5: 0.45, PVL 5698) is even lower than in other aetosaurs and in Aetosauroides the centrum length is longer than the height of the anterior articular facet (C 5: 1.16, PVL 2059). The lateral surface of the centrum of Aetobarbakinoides is concave and lacks a well-rimmed fossa (Fig. 3 C – D), as occurs in Neoaetosauroides (PVL 5698), Stagonolepis robertsoni (NHMUK R 4784), Desmatosuchus spurensis (Parker 2008), and Sierritasuchus (Parker et al. 2008). By contrast, well-rimmed lateral fossae are present in the centra of the entire presacral region of Aetosauroides (PVL 2059, 2073; MCP 13 - a-b-PV; Desojo & Ezcurra 2011). The cervical centrum of Aetobarbakinoides is constricted at mid-length in ventral view (Fig. 3 F). The ventral surface of the centrum completely lacks a median keel, resembling the condition observed in Desmatosuchus spurensis (Parker 2008), but contrasting with the sharp keels present in the cervical vertebrae of Aetosauroides (PVL 2059), Neoaetosauroides (PVL 5698), Stagonolepis robertsoni (Walker 1961: fig. 7 f), and Typothorax (Long & Murry 1995: fig. 102 c). The anterior articular facet of Aetobarbakinoides is 1.35 times transversely wider than the posterior one and also more ventrally extended (Fig. 3 A). The presence of an anterior articular facet wider than the posterior one is a condition also observed, but in a lesser degree, in Desmatosuchus spurensis (Parker 2008). In some specimens of Typothorax (e. g. TTU P- 9214; Martz 2002) the latter condition is also present but lesser developed than in Aetobarbakinoides, whereas in others the articular facets are sub-equal in width (e. g. AMNH 7634; Long & Murry 1995: fig. 102). In specimens of Aetosauroides (PVL 2059), Neoaetosauroides (PVL 5698), Stagonolepis (S. robertsoni: Walker 1961), and Sierritasuchus (Parker 2008: fig. 2) the anterior and posterior articular facets are always sub-equal in width. The outline of the anterior and posterior articular facets is circular in Aetobarbakinoides, resembling the condition of Stagonolepis (S. robertsoni: Walker 1961) and Sierritasuchus (Parker et al. 2008). By contrast, in Neoaetosauroides (Desojo & Baez 2005) and Typothorax (Martz 2002) these facets are oval, with a transverse main axis, and in Desmatosuchus spurensis are sub-rectangular (Parker 2008). The parapophyses are situated at the anterior margin of the centrum and are placed on a very low peduncle. The articular facet of the parapophysis is oval, being dorsoventrally taller than anteroposteriorly long (Fig. 3 E). Most of the neural arch is preserved, but only the base of the neural spine is available (Fig. 3 D). The preserved portion of the neural arch is higher than the centrum. The pedicles of the neural arch are parallel to each other and directly ventrally projected. Their lateral borders are slightly concave in anterior or posterior view. The neural canal is sub-quadrangular and its height is around two times lower than the height of the anterior articular surface of the centrum. A complete right diapophysis and the base of the left diapophysis are preserved. The diapophyses are dorsolaterally projected and short (Fig. 3 C). The distal articular surface is rounded and with an oval outline, and an oblique main axis, in which the upper portion is the anterodorsal. An anterior and a posterior infradiapophyseal lamina (sensu Salgado et al. 1997) are present below each diapophysis, as also occurs in Aetosauroides (PVL 2059) and, at least, in the posterior cervical vertebrae of Stagonolepis robertsoni (NHMUK 4784) and Desmatosuchus spurensis (Parker 2008). By contrast, the available cervical vertebrae of Neoaetosauroides do not present infradiapophyseal laminae (Desojo & Báez 2005). These laminae are well-preserved in the right side of the mid-cervical of Aetobarbakinoides and bound a central infradiapophyseal fossa. The diapophysis of Aetobarbakinoides is connected with the postzygapophysis through a sharp and well-developed postzygodiapophyseal lamina, only preserved in the right side of the element (Fig. 3 C). The latter lamina and the posterior infradiapophyseal lamina bound a shallow and wide posterior infradiapophyseal fossa, resembling the condition of Aetosauroides (PVL 2059), Stagonolepis robertsoni (NHMUK 4784), and Desmatosuchus spurensis (Parker 2008). The anterior infradiapophyseal fossa is absent. Only the base of the right prezygapophysis of the mid-cervical of Aetobarbakinoides is preserved. It has an oblique main axis with a dorsolateral upper end. The prezygapophysis is transversely wide at its base, being extended through most of the anterior edge of the diapophysis (Fig. 3: leprz). In contrast, in other known aetosaurs the prezygapophyses are more medially restricted than in Aetobarbakinoides, as occurs in Aetosauroides (PVL 2059), Neoaetosauroides (PVL 5698), Typothorax (TTU P- 9214), Desmatosuchus spurensis (Parker 2008), and Stagonolepis robertsoni (NHMUK 4784). Between the prezygapophyses exists a moderately deep and circular pre-spinal fossa, which is not dorsally extended along the neural spine. The postzygapophyses are anteroposteriorly short and slightly upturned. The articular facets are ventrolaterally oriented and with an oval outline, being transversely wider than anteroposteriorly long. Both postzygapophyses are connected at their mediodistal corner by a horizontal lamina which forms the dorsal border of the neural canal and defines a U-shaped hyposphene (Fig. 3 B). Directly above and between both postzygapophyses exists a deep post-spinal fossa. This fossa is dorsally extended on the posterior surface of the base of the neural spine as far as is preserved and at this region the fossa is laterally bounded by sharp spinopostzygapophyseal laminae, as also occurs in Desmatosuchus spurensis (Parker 2008). The base of the neural spine is only preserved and the available portion indicates that it was anteroposteriorly short. A shallow depression is present laterally to the base of the neural spine, but the deep circular pit found within it in some pseudosuchians is absent. The neural arch of the last cervical vertebra is preserved, lacking the left pedicle, prezygapophyses, left diapophysis, and the distal end of the neural spine (Fig. 4, 5 A, C). The right diapophysis is almost completely obscured by matrix and a cervical rib. The base of the right pedicle is available, but with a broken distal end. Only the base of the postzygadiapophyseal lamina is preserved. The postzygapophyses are anteroposteriorly short and the right one is mostly obscured by matrix and dorsal paramedian osteoderms. The left postzygapophysis lacks its distal end, but its preserved overall morphology resembles that of the above described cervical. A deep post-spinal fossa is present between both postzygapophyses and is extended dorsally on the neural spine. This fossa is co-laterally delimited by a pair of spinopostzygapophyseal laminae, resembling the condition exhibited by the cervicals of Desmatosuchus spurensis (Parker 2008). The presence of a hyposphene cannot be determined. The preserved portion of the neural spine is taller than anteroposteriorly long. An incipient depression is present lateral to the base of the neural spine and posteriorly displaced from the mid-length of the neural arch. Dorsal Vertebrae. An articulated series of nine complete anterior and middle dorsal vertebrae are preserved in the holotype of Aetobarbakinoides (Figs. 4 – 8). The dorsal vertebrae are moderately tall, with the neural arch ranging between 1.65 to 2.05 times higher than the centrum height along the preserved series, resembling the ratios observed in Desmatosuchus spurensis (Parker 2008) and Typothorax (TTU P- 9214). By contrast, in the neural arches of the posterior dorsal vertebrae of Stagonolepis (S. robertsoni: Walker 1961) this ratio is slightly lower than three times and in Aetosauroides (PVL 2073; MCP 13 a-b-PV; Desojo & Ezcurra 2011), the holotype of Calyptosuchus wellesi (Long & Murry 1995: fig. 75), and a putative Polish specimen of Stagonolepis robertsoni (sensu Lucas et al. 2007; ZPAL AbIII 502 / 67) the neural arch is three times higher than the centrum height. The centra of the dorsal vertebrae of Aetobarbakinoides are amphicoelous and subequal or slightly longer than their anterior articular facet height, with a ratio ranging from 1.04 - 1.1 in the first through third dorsals and 1.22 - 1.39 in the fourth through ninth dorsals. A similar condition is observed in the anterior dorsals of Typothorax (1.15: Martz 2002) and Desmatosuchus spurensis (0.95 - 1.42: Parker 2003, 2008) and the middle dorsals of Stagonolepis robertsoni (0.97: Walker 1961: fig. 7 k). In contrast, in the anterior and middle dorsals of Aetosauroides (1.5: PVL 2073) and anterior dorsals of Stagonolepis robertsoni (1.45: NHMUK R 4784; Walker 1961: fig. 7 i) and Sierritasuchus (1.46: Parker et al. 2008: fig. 2 g) the centrum is proportionally longer, being 1.45 - 1.5 longer than high. In ventral view, the centra are moderately transversely compressed at mid-length, acquiring an overall spool-shape. The ventral surface is convex and smooth, without a longitudinal keel or groove. The anterior and posterior articular facets are usually taller than wide, contrasting with the middle dorsals of Aetosauroides in which they are as tall as wide (Desojo & Ezcurra 2011). However, in the ninth dorsal of Aetobarbakinoides the articular facets are wider than tall, as occurs in the posterior dorsals of Aetosauroides (Desojo & Ezcurra 2011). None of the available dorsal centra do exhibit lateral fossae. These fossae are also absent in Stagonolepis robertsoni (Walker 1961; ZPAL AbIII 502 / 67), Calyptosuchus wellesi (Long & Murry 1995), Typothorax coccinarum (Martz, 2002), Tecovasuchus chatterjeei (Martz & Small 2006), and Neoaetosauroides (PVL 3525). In contrast, Aetosauroides exhibits an oval shallow lateral fossa in the presacral vertebral centra (Desojo & Ezcurra 2011). In the available dorsal series of Aetobarbakinoides the infradiapophyseal laminae are incipient or completely absent. A very faint posterior infradiapophyseal lamina is present in the middle dorsals (e. g. D 9) (Fig. 8). Conversely, better developed infradiapophyseal laminae are present in the dorsal vertebrae of Aetosauroides (Desojo & Ezcurra 2011), Stagonolepis robertsoni (NHMUK R 4784), Desmatosuchus spurensis (Parker 2008), and Typothorax coccinarum (Martz 2002). The infradiapophyseal laminae are absent in Neoaetosauroides (PVL 3525) and the Polish Stagonolepis (ZPAL AbIII 502 / 67). No traces of anterior infradiapophyseal fossae are observed, resembling the condition of Aetosauroides (Desojo & Ezcurra 2011). In the first through eighth dorsals the central and posterior infradiapophyseal fossae are absent in Aetobarbakinoides (Figs. 5 – 7), but incipient central and posterior infradiapophyseal fossae are present in the ninth dorsal. The latter contrasts with the well-defined central and posterior infradiapophyseal fossae observed in Aetosauroides (Desojo & Ezcurra 2011). As occurs in Aetosauroides, in Aetobarbakinoides the transverse processes are anteriorly displaced from the mid-length point of the neural arch. In the first through eighth dorsals, the transverse processes are dorsolaterally projected, but they are directly laterally oriented in the ninth dorsal. The transverse processes are sub-rectangular in dorsal view, which is the same condition observed in Stagonolepis robertsoni (NHMUK R 4784), Neoaetosauroides (PVL 3525), and Desmatosuchus spurensis (Parker, 2008). In contrast, in Aetosauroides the transverse processes are trapezoideal in dorsal view (PVL 2073, MCP 13 - a-b-PV; Desojo & Ezcurra 2011). The prezygapophyses are very anteroposteriorly short, without a well-developed pedicle, and with dorsomedially oriented articular facets, resembling the condition of Aetosauroides (PVL 2073; MCP 13 - a-b-PV), Stagonolepis (S. robertsoni: Walker 1961), and Typothorax (Martz 2002). In dorsal 9 of Aetobarbakinoides the right prezygapophysis is complete and well exposed, exhibiting a sub-rectangular articular facet with a transverse main axis (Fig. 9). The postzygapophyses are longer than the prezygapophyses, but they do not reach the mid-length of the subsequent vertebra, resembling the condition of Typothorax (Martz 2002). The postzygapophyses of the dorsal vertebrae of Aetosauroides (Desojo & Ezcurra 2011) and Stagonolepis (S. robertsoni: Walker 1961) extend posteriorly up to the mid-length of the subsequent neural arch. Conversely, in Desmatosuchus spurensis (Parker 2008) and the Polish Stagonolepis robertsoni (ZPAL AbIII 502 / 67) the postzygapophyses are extremely posteriorly short. An anteriorly shallow median notch separates the postzygapophyses of the dorsal vertebrae of Aetobarbakinoides. This median notch is deeper in Stagonolepis (S. robertsoni: Walker 1961) than in Aetobarbakinoides. In Aetosauroides the postzygapophyses are posterolaterally projected, resulting in strongly divergent apophyses with an even transversely wider median notch than in Stagonolepis robertsoni in dorsal view (Desojo & Ezcurra 2011). In the first through eighth dorsals of Aetobarbakinoides the postzygapophyses exhibit a lateral triangular projection, resulting in an oval articular facet with a transverse main axis in ventral view (Figs. 5 – 7). In contrast, in the ninth dorsal this lateral projection is lacking and the lateral margin of the postzygapophyses is slightly convex and consequently the articular facets are circular (Fig. 8). A well-developed Y-shaped hyposphene is present in all the available dorsal vertebrae of Aetobarbakinoides in which this region is exposed, as also occurs in Desmatosuchus spurensis (Parker 2008). In contrast, in Aetosauroides these structures are completely absent (PVL 2073; MCP 13 - a-b-PV). The postzygadiapophyseal lamina is well-developed in all the preserved dorsal vertebrae, resembling the condition present in Aetosauroides (Desojo & Ezcurra 2011). At both sides of the neural spine of all preserved dorsals, a deep and circular pit is present at the posterior level of the transverse process (Fig. 8: dlp). This condition is widely observed among pseudosuchians (e. g. Batrachotomus: Gower & Schoch 2009), but absent in Aetosauroides (PVL 2073; MCP 13 - a-b-PV) and still unreported in other aetosaurs. The neural spines of the first through eighth dorsals of Aetobarbakinoides are dorsally directed (Figs. 4 – 7), as also occurs in Desmatosuchus spurensis (Parker 2008), the Polish Stagonolepis robertsoni (ZPAL AbIII 502 / 67), and Calyptosuchus wellesi (Long & Murry 1995). However, in the ninth dorsal the neural spine is anterodorsally projected, resembling the anterior and middle dorsals of Aetosauroides (PVL 2073; MCP 13 - a-b-PV), and posterior dorsals of Stagonolepis (S. robertsoni: Walker 1961) and Typothorax (Martz 2002). In the first through eighth dorsals of Aetobarbakinoides the neural spine is taller than anteroposteriorly long, but in the ninth dorsal the neural spine is as tall as long (Fig. 8), resembling the morphological change observed along the dorsal series of Aetosauroides (PVL 2073). The distal end of the neural spine of the fifth, sixth, and ninth dorsals are moderately expanded transversely into spine-tables, resembling the condition of the Aetosauroides specimens PVL 2073 and PVL 2052, Stagonolepis robertsoni (NHMUK R 4784), and Calyptosuchus wellesi (Long & Murry 1995). In contrast, better transversely developed spine tables are present in Desmatosuchus spurensis (Parker 2008), Longosuchus (Sawin 1947), and Typothorax (Martz 2002). The spine tables of Aetobarbakinoides are drop-shaped in dorsal view, with the widest end anteriorly positioned. This condition resembles that of the drop-shaped spine tables of Sierritasuchus (Parker et al. 2008) and Stagonolepis (S. robertsoni: Walker 1961), but contrasts with the oval spine tables of the entire dorsal series of Aetosauroides (PVL 2073) and the sub-rectangular ones of Typothorax (Martz 2002). In Desmatosuchus spurensis a strong variation in shape of the spine table is observed through the dorsal and caudal series, ranging from sub-rectangular in anteriormost dorsals, oval in more posterior anterior dorsals, drop-shaped with a posteriorly positioned main transverse axis in middle dorsals, drop-shaped with an anteriorly positioned main transverse axis in posterior dorsals, and oval to circular in anterior caudals (Parker 2008). The post-spinal fossae are moderately deep, sub-triangular, and do not extend dorsally into the neural spine. Unfortunately, the presence of pre-spinal fossae cannot be confirmed.	en	Desojo, Julia B., Ezcurra, Martín D., Kischlat, Edio E.
