Re: PLEUROCOELOUS VERTEBRAE IN SAUROPODS



How little most people understand about heat problems in land giants. 

1 - Giant animals are not in particular danger of overheating, they store it
in the daytime and dump it at night. 

2 - Large animals cannot use their deep respiratory tract to shed heat. Doing
so requires breathing both rapidly and energy efficiently. Doing that
requires breathing at the resonant frequency of the ribcage, and frequency
drops off with size. Even ostrich ribcages are too big for them to use their
air-sacs for air cooling. Sauropods could not use their air-sacs for cooling.

This overheating nightmare will never end.
