Re: Size limits

AFAIK someone calculated a theoretical limit for quadrupedal land
animals at 140 t because then the legs have to be so thick that they
touch. BTW, I don't believe the 100-t-estimate for Argentinosaurus --
Brachiosaurus has been credited with serious estimates between 15 and
75 t, for example; I prefer the former estimate, because most
titanosauriforms had more air than bone in their vertebrae and must have
had large air sacs.
Moreover, these large herbivores certainly fermented their food. That
means large amount of gas in the stomach/intestine. Thus, major part of
their volume would have been gas.
Did all those methane keep the Mesozoic so warm :)
