Re: Even more on dino metabolics



Your comment is irrelevant. Please address the specific assertions I make,
not vaque side issues. I did 
not argue that all animals with gastralia used them to ventilate air-sacs.
Hengst & Rigby 1994 denied that sauropods had air-sacs in part because they
lacked gastralia to help ventilate them with. We now know sauropods did have
same.
