Subject: R: Sexual Dimorphism (was T.rex Q & A)




<I don't known if there are some sexual dimorphism in Psittacosaurus, but if
I remember correctly the sexual dimorphism proposed for Heterodontosaurus is
based on the presence in some skulls of caniniform teeth, that actually not
represent true sexual dimorphism but two distinct genera Heterodontosaurus
(presence of caniniform teeth) and Abrictosaurus (absence of caniniform
teeth).>

I was aware of the fact Heterodontosaurus  and Abrictosaurus have been
considered as being distinct genera. However, the case might not be
dismissed, yet.
