Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| O. A. Alcober and R. N. Martínez 2010 | Diagnosed by the following autapomorphies: shelf-like, posterolaterally directed transverse processes on the posterior cervical vertebrae; neural spines of the sixth to eighth dorsal vertebrae, at least, bearing acute anterior and posterior processes; everted lateral margins of the glenoid; short pubis (63% of the femoral length); and pronounced, rugose scar on the medial surface of the femur at the level of the fourth trochanter.
These features distinguish Sanjuansaurus gordilloi from the previously described herrerasaurids, such as Herrerasaurus ischigualastensis and Staurikosaurus pricei, as well as other basal saurischians from Ischigualasto Formation, such as Eoraptor lunensis (Sereno et al. 1993), Panphagia protos (Martinez and Alcober 2009), and Chromogisaurus novasi (Ezcurra 2008, 2010). |
