Re: Unidirectional gator breathing in Science

Jeez, an irrelevant to the idea paper in Science and deep snorkeling 
sauropod drivel. 

Because sauropods were so pneumatic they would have chronically floated, 
not sunk to the bottom like nonpneumatic, heavy boned aquatic animals.

None of the examples cited breaths with the body under high water pressure 
(humans can breath through a tube a couple of feet under, surface swimming 
snorkeling elephants breath with the lungs a few feet below the surface). 
Water pressure more a couple of meters would have prevented inhalation 
regardless of respiratory design.
