Re: Segnosaurs Analyzed as Prosauropods
I was wondering if the swollen parbasisphenoid was a potential synapomorphy
of the Ornithomimosaur-therizinosaur clade? Is a similar swollen pbs seen in
other theropods lineages ?. What is the biological function of the swollen
Also has Mr. Mortimer examined the state of the coronoid in the
Ornithomimosaurs: Is it not reported to be missing in Orinithoms and
Therizis but present though in a peculiar form in the oviraptorosaurs.
It would be nice to hear from you experts on the possible evolutionary
significance of the variations in the coronoid in the theropods.
