To be fair (coming from someone obsessed with tyrannosaurid food), I have
run across at least one juvenile Triceratops horncore in about every major
museum collection I've looked at. London has one or two (picked up by the
Sternbergs), Hatcher picked up a few (now at the Smithsonian), etc. They
were just never published. On the other hand, I never have seen any tiny
femora, etc. . .maybe the horns were just the least appetizing bit of the
Then again, maybe this juvenile material comes in fits and spurts. There has
been no problem finding juvenile Triceratops skulls in recent years (or
finding T. rex skeletons, for that matter!).
