The _T. rex_ arm strength estimate was done at the Museum of the
in Bozeman, MT. Jack Horner runs the Vert. Paleo. there, but I
the work was done by Ken Carpenter, who was there at the time.
The original estimates were based on the _T. rex_ that Horner
that had the first complete set of arms. I believe the lifting
320 lbs. in a single arm curl (I seem to remember that there was an
if the arms were scaled up to a more robust form [ presumed female
then it could curl 450 lbs).
Yes, that sounds right. I believe I heard this estimate in a
Discovery Channel interview with James Horner a year or 2 ago. The grist of
the interview was
The predator/scavenger "debate" that was new at that time. IS
dimorphism an accepted fact in tyrannosaurs? I'm NOT disputing it, I was
just wondering how much scientific evidence there is for it?
