Re: T rex brooding
The _T. rex_ arm strength estimate was done at the Museum of the Rockies
in Bozeman, MT. Jack Horner runs the Vert. Paleo. there, but I recall that
the work was done by Ken Carpenter, who was there at the time.
The original estimates were based on the _T. rex_ that Horner dug up
that had the first complete set of arms. I believe the lifting power was
320 lbs. in a single arm curl (I seem to remember that there was an estimate
if the arms were scaled up to a more robust form [ presumed female by most],
then it could curl 450 lbs).
