Re: MARGINOCEPHALIANS and Triassic times

Both domes look exactly like pachycephalosaur
domes and unlike anything else ever found, so
it is reasonable to conclude that that is what they are.
By the same reasoning, Protoavis has features that
are present only in birds (and there is a fair amount of it)
and Shuvosaurus' skull looks exactly like an ornithomimid
and not a Poposaurid. Chatterjee is actually pretty bright
and not someone who is simply looking for fame and fortune.
Not being an expert but having a good deal of knowledge and
experience in paleo, I was skeptical about all of the above but
can find no reason to discount any of it, with the exception of the old
reasoning, "it's too late (or early in these cases)," or political reasons.
The stuff is real.
