Diagnosis
ReferenceDiagnosis
J. Fröbisch and R. R. Reisz 2011Small venyukovioid characterized by the following autapomorphies: large orbit, nearly one-third of skull length; frontal–parietal suture occurring at rim of pineal foramen; postorbital–squamosal contact present ventrally (convergent with Chainosauria); teeth large relative to skull; wear facets nearly parasagittal; tooth wear striations indicate propalinal motion of mandible that extends each dentary toothacross at least two maxillary teeth; reduced number of 23 presacral and therein 17 dorsal vertebrae; centra of cervical vertebrae longer than wide, indicating an elongate neck; transverse processes of caudal vertebrae fuse to long caudal ribs; procoracoid with indentation at ventromedial margin rather than foramen; iliac blade with robust ridge on anterior edge of medial surface; pubis with puboischiadic fenestra and separate pubic foramen; limbs elongated; manus equals 40% of forelimb length; distal carpal 1 and tarsal 1 enlarged, phalangiform, and diverge laterally; metacarpal I short and robust; crescent-shaped distal tarsal 4; penultimate phalan- ges elongated; manual phalangeal formula 2-3-4-5-3 and pedal phalangeal formula 2-3-4-5-4, with disc- shaped phalangeal elements in digits III and IV (manus and pes) and digit V (pes only).
