I find it interesting in comparison to look at Megalancosaurus (check out
Dave Peter`s website at:
http://home.stlnet.com/~azero/Megalancosaurid.html ). It has tall neural
spines, and it`s feet seem well adapted for grasping narrow branches. I
can`t shake the thought that perhaps Ornithishians had evolved from this
type of Prolacertiform. Of course perhaps this just follows suit from my
(somewhat extreme) view that the path to theropods took the form
prolacertiform (cosesaurus-like)>pterosaur>bird>theropod (secondarally
flightless). After all,....The ornithishian-saurishian split did occur early
on, and the prolacertiforms were around at just about the right time, and
were fairly well diversified.
