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.

T. rex (popular press--link below). Perhaps there's some-

and I applaud that.

But of course a full grown T. rex didn't run down its prey.

Apparently it could not, but in any case it didn't have to.

Much easier to take over a kill from a lessor carnivore.
Hasn't Horner been saying this for years?  What no one
ever seems to mention (correct me if i'm wrong) is that
*juvenile* T. rexes must have been fearsome predators.
One weighing in at about a ton, perhaps. Does anyone
know what's been published on this (non-hypothetical)?
What's the allometry of the hindlimbs? Has anyone estim-
ated the speed/agility of a juvenile or subadult T. rex?
