RE: Coelophysid Distribution & Evolution

[Ivan Kwan <dino_rampage@hotmail.com>]

Coelophysoids certainly were the first bunch of theropods to have really 
made it big and spread throughout the world; even the herrerasaurs seem a 
lot less common and more rare.

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 
run.
