   THANK YOU.  Finally, someone says (at least that I've noticed) what I've
been thinking for years.  Every time I see a Horner interview where he talks
about _T. rex_ not being a hunter because it couldn't attack a _Triceratops_
I end up screaming at the TV *why*?  *Why* would a _T. rex_ attack a big,
heavily armored trike when hundreds of thousands of hadrosaurs (as I call
them here "tyrannosaur snacks," and the giant herds of which Horner was
among those that discovered them for bleeps sake) were milling around just
waiting to be digested.

   I do recall, however, a trike fossil with a _T. rex_ bite in it.  If the
wound was inflicted during life, it's interesting to note the _T. rex_ was
biting it in the butt, far from those big horns.....
