Re: Sauropod browsing energetics
Given that elephants are known to need to forage as much as 22 hours
a day to find enough food, and sauropods were much bigger than
elephants (apparently because they *had* to be) -- it seems doubtful
that *anything* outweighed an increase in absolute browsing capacity,
in terms of evolutionary advantage accruing to certain morphological
Elephants chew. Sauropods couldn't.
If you know a way to test whether food intake rate was a limiting factor
for sauropods, please tell.
