Diagnosis
ReferenceDiagnosis
G. S. Paul 1993Gracile skull and skeleton. Post temporal fenestra absent, teeth small, row of 19-20 maxillary teeth ends beneath antorbital fenestra, 25 dentary teeth. Neck relatively short. Pubis shorter than femur, no distal pubic expansions, distal ischial expansion relatively small, hindlimbs relatively long.
M. T. Carrano et al. 2012Coelophysoid theropod with: (1) blunt, squared anterior margin of antorbital fossa; (2) base of lacrimal vertical ramus width < 30% its height; and (3) maxillary and dentary tooth rows end posteriorly at anterior rim of lacrimal (all from Bristowe & Raath 2004).
