Re: T. rex



The theme "T.rex the scavenger vs. T.rex the active predator" seems to keep
getting back in traffic (Dino list) in a cyclical mode.
The questions are: Were there ever enough big carcasses around to support a
viable T.rex community? (there were dozens of other opportunistic feeders
around who would get to the carcass and finish it up before the rare T.rex
might have detected it). Why did the evolution keep supplying the big
predatory dinosaurs with ever longer legs, bigger teeth and shorter arms,
during the millions of years?(to be faster than competition in getting to
the carcass?) Is there any extant big predator which is exclusively a
scavenger?
