The basic conclusion: big _T. rex_ specimens did not have sufficient muscle
mass to be able to produce a fast run.
Currie seemed very interested at the Burpee Museum this weekend in
the possibility that young members of a _Tyrannosaurus_ "herd" may
have done the majority of the hunting. Speculation, of course, but
he points to the _Albertosaurus_ bone beds in Alberta as evidence
that tyrannosaurids may have been gregarious. He extrapolated these
data to speculate that perhaps the more agile youngsters may have
done the hunting for the older, slower adults.
