Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. P. Hunt et al. 1998 | Herrerasaur whose ilium differs from Staurikosaurus and Herrerasaurus in possessing: (1) an elongate and dorsoventrally narrow posterior blade; (2) a narrow ridge on the lateral margin that extends from the anterodorsal margin of the acetabulum to the anterodorsal anterior spine (senu Novas, 1993); (3) a highly reduced brevis fossa; and (4) a semicircular margin dorsal to the acetabulum; differs from Chindesaurus bryansmalli in possessing a less deep brevis shelf which does not extend to the posterior margin, a lateral longitudinal ridge (for sacral rib articulation) which is placed more ventrally and a much thinner (less than half) posterior blade in dorsal view. |
