Re: [Re: Sauroponderings]
I missed part of this thread due to mail problems, so I hope this
hasn't already been visited...
Elephants don't drink directly. They pick up water with their trunks
and spray it into their mouths. This made me wonder if sauropods may
have a more complex mechanism themselves. The only thing that came
to mind was, if they got a gulp of water, then raised their heads and
let gravity assist the swallowing. Could their heads even lower enough
to get to water? The lapping/sucking idea would seem to require a very
good vacuum to get water up through the neck. Heck, could you even
do it beyond the 32 foot limit by air pressure (that is, 32 feet is
the amount water will raise in a vacuum when subjected to 1 atmosphere
of pressure outside the vacuum).
