Re: Dakota the Dinosaur Mummy

I'll join the other skeptics here and suggest that many factors other than simply the mass of the hip muscles would factor into an analysis of running ability; muscle shape, for one thing, and the moment arms of the muscles about the hip for another. I don't know if these can be determined from this fossil or not, but they are important. Also, as Michael states, this says nothing about T. rex.

Wouldn't we need a mummified _Tyrannosaurus_ to be sure of that?
