Re: T. rex was a 'slow-turning plodder'...

The theropod-style skeletal elements, with their thinner walls and larger medullary cavities (compared to mammals) probably doesn't do much to reduce overall mass (the reason being that the overall volume of bones tends to be greater).

Are adjustments for size taken in account here (i.e. we're not comparing the bones of a T. rex with those of a bipedal savanna ape)?
