Stuff on the agility of T. rex

["Henri Rönkkö" <overmind@iobox.fi>]

 Dear all,

I am in a need for stuff on the agility, and speed, of T. rex. I have already 
found Neil McAlexander's article appeared in Scientific American. If you have 
any references, I'd be pleased to hear about them.

Things in which I'm particularly interested are mass estimates and leverages 
for muscles deducted from the locations of muscle scars.

Yours truly,
Henri Rönkkö
