A poor excuse. If one pachycephalosaur with a well developed dome lacks
these specializations, why should another have them, even hypothetically? I
may not be able to prove Prenocephale had such cervical specialiations, but
it's most parsimonious to conclude it lacked them.

There are no described manual remains of Rajasaurus, but if you have
unpublished data, perhaps you'd like to share it.
I was actually basing my assertion on Aucasaurus, which has four fingers
that each seem long and divergent enough to be visible in life.

And my calculations suggests described Carcharodontosaurus individuals were
shorter than described Tyrannosaurus individuals too.
