Re: What did Spinosaurus eat? New species of Lepidotes found
I know I owe people a couple of responses... I'll get to them sometime. :-(
-I think that the bird models have some adventages. First, it seems
spinosaurids were no specialized swimmers, as far as can be seen
from baryonychines, and would more resemble wading birds in locomotor
style (although another problem: their limb proportions more closely
resemble the short-limbed paddling birds!). Spinosaurines may have
better swimming abilities (unknown because of the lack of limbs),
but parsimony and the sail/hump do not suggest so.
Great. Now I have the mental image of a 17-m-long *Spinosaurus* paddling
around like a duck with a sail on its back and a mean, mean, mean
Third, the longer neck may help with a
source of precision crocs seem not to have.
-Regarding [...] Bailey's hump hypothesis...
No. Just... no. :-)
No, really, there's no evidence for a hump. There just happen not to be
any mammals with a sail, and Bailey doesn't seem to have looked at
squamates like *Hydrosaurus* very much.
