Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. P. Hunt et al. 1998 | Theropod that differs from all ceratosaurs except Rioarribasaurus and Syntarsus in possessing tarsals fused to the tibia and fibula and differs from Rioarribasaurus and Syntarsus in that the ventral margin of the astragalus in anterior/posterior view is horizontal rather than deeply concave (Long & Murry 1995) and further differs from Coelophysis in that the fibula was in contact with the tibia in anterior view for a distance equal to at least one and a half times the width of the astragalus plus calcaneum (compare Colbert 1989, fig. 87A)/ | |
| M. D. Ezcurra and S. L. Brusatte 2011 | Same as for the only known species. |
