While I've seen some people supporting this position of Avimimus onlist, exactly what are your reasons?
Oho! Someone's putting old Archie closer to Dromaeosauridae than to birds, and nobody protests? :-) Are people now generally accepting Paul 1988 and :-> :-> Marjanovic 2000 who said that Archie doesn't share more with Pygostylia than with dromaeosaurids?
Can I begin waiting for a paper? :-)
Regarding the next post in this thread:
What is Neocoelurosauria?
Why do you put Timimus into Avimimidae? (Not that I knew of a reason, other than general ignorance, of not doing so...)
What are proto-tyrannosaurs?
What unites your Iliosuchidae?
Aublysodon, Shanshanosaurus, Dinotyrannus and Nanotyrannus have recently turned out to be juveniles of Tyrannosaurus, Tarbosaurus, Tyrannosaurus and Tyrannosaurus, respectively, IIRC.
Deinodon is just a couple of undiagnostic tyrannosaurid teeth AFAIK, and a nomen dubium (the reason why nobody uses it).
Regarding the sculpture by HP Allan Smith:
So far, as far as I can tell, perfect. :-) The sickle claw looks very small to me, but I don't know how it really is in the fossil.
