Re: Jobaria and the Elephant Commit Suicide
>> sauropod would not have to rear up fully for this to be effective.
Consider the relative sizes of the sauropod and the carnosaur. A pushoff
gains height for the sauropod, and this makes for quite a landing. If the
carnosaur had actually tried its entry at this point, the sauropod body
would've come down right on it.
Behaviorally, a better model, I think, would be a horse. Horses rear, and
can actually go bipedal for a few moments and their rearing behavior is
used for defense.<<
But think of how much larger sauropods are than horses! When a horse rears, the
worst that can happen to it is it sprains its wrists if it comes down wrong. A
sauropod, however, would be putting incredible stresses onto its fourlimbs when
came back down. Could the bones in its arm take the sudden compression?
Don't forget, rearing up gives the impression of being larger. Many
animals do the equivalent - like raising fur or having a mane.<<
As if sauropods needed to be any larger.
