Diagnosis
ReferenceDiagnosis
A. Bristowe and M. A. Raath 2004The diagnosis of the genus Coelophysis is founded on a hypodigm consisting of the specimens discovered by Cope and attributed to C. bauri and the species regarded as synonyms, C. longicollis and C. willistoni, as well as complete skeletons of C. bauri excavated at Ghost Ranch, New Mexico, by Colbert. Coelophysis differs from Eoraptor, Herrerasaurus and Staurikosaurus by the presence of pleurocoels in the dorsal vertebrae, the more elongated dorsal vertebrae, five fused sacral vertebrae, dolichoiliac ilium, presence of a small lateral projection on the distal end of the tibia and the functionally tridactyl foot with metatarsal I that is attached to metatarsal II and does not reach the ankle joint (Rauhut 2003). It differs from Gojirasaurus in the relatively lower dorsal neural spines and the significantly smaller size, from Liliensternus in the absence of the broad ridge that extends from the posterior end of the diapophysis to the posterior end of the vertebral centrum in cervical vertebrae and the smaller size, from Procompsognathus in the considerably larger overall size, and from Shuvosaurus in the lack of any derived cranial features of the latter taxon (Rauhut 2003). The posterolateral nasal process is the same in C. bauri as in C. rhodesiensis and C. kayentakatae.
