I'm not criticising here Nick, but there is some published
palaeoneurological work showing that tyrannosaurs and carnotaurs had
degenerate forelimbs not suited for much use (kind of see things as a
bit more complex myself though).  Journal of Zoology late last year.

Yeah, it's an old debate. Me: I think _T. rex_ used those arms to push
itself up after lying on its belly. Yeah, and humans *are* the spawn
of the aquatic Nommos from Sirius B....
