Re: Blood flow in Sauropods
Even if the problems of blood pressure is solved or
disregarded, I see two big problems reamaining with tripodal sauropods:
1. How do they get up in the first place? The body anterior to
the sacrum (including the body cavity and that long neck) must
have bee pretty heavy. Could the forelimbs have provided enough
push to get that mass off the ground?
2. Coming back down: Again, presacral mass must have been
signifigant. That weight hitting the ground would put some serious
stress on the forelimbs.
Has anyone played around with the numbers here? Exactly
how much presacral mass would a Apatosaur or Diplodocid have?
How about the strength of the forelimbs?
