RE: sauropod lung collapse



But these animals don't have a long neck (snorkel), but rather their
bodies are at the surface when they breathe.

This doesn't clinch the case, does it?   Plenty of large animals like
hippopotamuses and, yes, whales manage to spend quite a bit of time deep
under water without having collapsed lungs and do their breathing when
they're safely above water.

testing is easy: stand vertically submerged in the deep end of a
swimming pool and use a snorkel with only 3 " above the water - you can
hardly breathe. Yet, your chest is only about 18" (or less) below the
surface.

I've heard it said time and again that large sauropods could not have
lived underwater because the pressure of the overlaying water column
would have crushed the lungs or at least prevented the animal from
inflating them.  Has this been tested and published anywhere?
Thanks,
