Re: Is Jack Horner right about T-rex?



MegaRaptor (Mike), Dwight, Larry, et al:

    As Dwight said, there has been quite a bit of discussion on this list
about the scavenger vs predator issue for _T. rex_.  I won't reiterate it
here, except to say that I heard Tom Holtz's talk about the subject and I
agree with him that _T. rex_ was most likely an active predator, and an
occasional scavenger.

    Mike - If you want, I can send you several of the posts on the subject
(I keep a private archive of the list - about 18 months worth).  By my most
recent count, that's approvimately 85+ postings since last February (1998).
Let me know.
