Re: late night thoughts: not all T. rexes were adults

This idea was presented in one of the CG dinosaur shows on the
Discovery Channel, I'm totally blanking on which one though.  The
basic idea was the juveniles chase the prey and corral it and then the
bigger ones jump out of the brush and take it down.

I've always been bothered by the idea that fully-grown /T. rex/ were ambush predators. Their long slender limbs and high CG seem utterly unsuited to "jumping out from behind a bush" to me.

My armwaving guess is that they walked down sick/old/injured prey, relying on those long legs to give a more efficient gait. When the prey were sick of walking and exhausted: CHOMP!
