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

Surely if you're going to out-walk your prey to death you need to make
sure it's not galloping out of sight - any objections to ambush + bite
to the hips to severely cripple it, then walk it to death?

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!
