Re: B. walkeri neural spines

[Christopher Collinson <Chris_Collinson@monarch.net>]

Why do people immediately look to a mammalian analogue when there are better
reptilian examples? For one thing I'd like to know how Spinosaurus could
have walked with so much weight so far forward of its hips. Someone on the
list previously brought up the possibility of a Chameleons analogue, where
many species have high spined vertebra, some more so than others, but do not
store fat on them. Like all other reptile, not including birds of course,
Chameleons store fat in their tails its probable to assume most dinosaurs
did the same.

Cheers,
Christopher Collinson
