Temporal range: Late Triassic-Early Jurassic, 220–183Ma
|Artist's restoration of Coelophysis bauri|
Under cladistic analysis, Coelophysidae was first defined by Paul Sereno in 1998 as the most recent common ancestor of Coelophysis bauri and Procompsognathus triassicus, and all of that common ancestor's descendants.
Coelophysidae is part of the clade Coelophysoidea. The older term "Podokesauridae", named 14 years prior to Coelophysidae (which would normally grant it priority), is now usually ignored, since its type specimen was destroyed in a fire and can no longer be compared to new finds.
