Re: Deinonychus - one or two species?
<<Anyways, on to the title scoop. It seems that the new Deinonychus
skull material has pretty much put to rest the idea of
Velociraptor-snouted dienicks. Rather, Deinonychus had a vaulted,
robust skull all along. I went along with this development for a while.
Then, when I was talking to Greg Paul at this year's DinoFest, I asked
him if he was going to update his Deinonychus skeletal restoration. He
told me that the skull with the Velociraptor-type snout was probably
real and that he was going to the Peabody Museum to prove or disprove
Witmer illustrated the Deinonychus skull with a Velociraptor-like snout
in his antorbital cavity monograph. Plus, I thought that it was said
that the new skull is really similiar to both Ostrom's original
reconstruction and Paul's revised reconstruction (still has the
Velociraptor snout but has a large sagittal crest).
