RE: Coelophysid Distribution & Evolution
Coelophysoids certainly were the first bunch of theropods to have really
made it big and spread throughout the world; even the herrerasaurs seem a

There was that theory put forward by GSP that _Elaphrosaurus_ was a relict
coelophysoid, though I think the current stand now is that it seems more
likely to have affinities with the noasaurids.
And as for the North American coelophysoids, there's also _Camposaurus
arizonensis_, _Eucoelophysis baldwini_, and _Podokesaurus holyokensis_,
though, given how scrappy all of these are, maybe they all belong under
Coelophysis as well.

No, _Liliensternus_ and _Dilophosaurus_ are Early Jurassic. If there were
any coelophysoids known from after the Early Jurassic, I'd like to hear
about them. Looks like they may have gone extinct then. They had a good
