RE: tyrannosaurid feeding ecology
From: Tim Donovan <email@example.com>
The 1988 tail bite paper mentioned a pit in one of the mangled caudals,
interpreted by the author as a toothmark.
Did you mean to say the 1998 Gaia paper? If not, which 1988 paper are you
The thing about the traumatized edmontosaur 15th caudal vertebra is that it
isn't pitted, as you mentioned, so much as the entire upper third is
entirely missing! What sort of bone disease could do that? (I'm completely
ignorant of the subject.) Combine that with the fact that the surrounding
vertebrae show trauma in sections where one would expect the circumference
of a tyrannosaur bite to follow, and I think Dr. Carpenter makes a pretty
strong case for tyrannosaurid predation.
Hasta la vista.
