Re: Removing segnosaurs from ...

Right on the money here. Look in "The Dinosauria" at figures 18-1 E,
18-2 B, and 15-2 E; which depict the inner jaws of _Erlikosaurus_,
_Segnosaurus_, and _Plateosaurus_ respectively. The prearticular is
very similar in _E._ and _P._, as is the general structure of the inner
jaw bones in all three forms.
I did goof when I listed trait number 19 as interdental plates; it should
be interdental plates that are small compaired to the tooth size.
About the foot. Segnosaur feet are just about identicle to
prosauropod feet. Thom Holtz claims this is a reversion. This cannot
be a reversion because to revert to a former condition, you MUST
have that condition in your ancestory; and unless Thom Holtz is
claiming that Prosauropods are ancestors of Theropods, theropods
never had a prosauropod foot in their ancestory, so the segnosaurs'
foot is not a reversion.
