> And then, I would like to know if these "clavicles"
from Oviraptor and the theropod Camp found (it would also be nice to know
what theropod this was) were real furculas or just usual clavicles. I believe
clavicles are primitive character of Tetanurans.
Actually, Tykowski's disseration on Syntarsus describes the
presence of a furcula in that form, and probable Coelophysis furculae
have been identified by Downs. This, combined with the fact that the
Carnotaurus clavicle element is damaged and the symphsis is not
accessible strongly supports the idea that furculae, rather than unpaired
clavicles, are the basal condition for Neotheropoda (ceratosaurs plus
tetanurines).
