Ah, but _Coelophysidae_ was *defined* first. (Podokesauridae has never
been explicityly defined, TMK.)

We're back to the _Mononykinae_ vs. Parvicursorinae issue, and this isn't
far removed from the Segnosauria/_Therizinosauria_ issue, either.

Following traditional taxonomy and the ICZN, Familia Podokesauridae is
correct, but following cladistic taxonomy and precedence of definition,
_Coelophysidae_ is correct.

(There's also the issue, as DinoGeorge notes, of whether _Podokesaurus_
and _Coelophysis_ really are synonyms.)
