Re: T. rex vs Edmontosaurus speed
It's not quite that simple - first of all, it is not absolute muscle
mass, but muscle mass relative to body weight that is important, i.e.,
how large is the percentage of the body mass that is concentrated in
the muscles. Furthermore, there is the question of how the muscles act
- moment arms of the muscles and length of the limb segments.
If you want to see how to calculate with this kind of things, look at
the papers by John Hutchinson.
