After watching a fascinating documentary on the Tyrannosaurus and the possibility that it was a scavenger, I got to thinking–what was with those arms?
If Tyrannosaurus ran at a full sprint, assuming it could run at all, and tripped, it would die. A similarly-sized dinosaur with better arms would possibly be able to break its fall–any word on that dinosaur discovered in Africa that was bigger than old Rexy?
But even if Tyrannosaurus were a scavenger, what purpose could possibly have been served by pitifully small arms like that? I understand that it wouldn’t have to run very fast if it just ate things already dead, thereby eliminating that nasty fall-down-go-boom problem, but surely the arms could still be useful. How’d this beastie get up in the morning, assuming it slept on its belly?
