Re: Blood flow in Sauropods
Actually, the spred legging of drinking giraffes may not have to do with
blood pressure problems. I have seen film of Okapi with short necks drinking
the same way!
Most sauropods probably had a giraffe-like neck set up, in which the neck was
strongly flexed up at the base, and bringing the head down to drink was
difficult (perhaps some sauropods spread of flexed their forelegs). If so
then some means of keeping BP in the brain from soaring to extreme levels was
necessary, but its nature will probably never be known.
