Re: Sauropod necks????

I  must confess ignorance of (first name, honorific?)
Holland or his work.

I was trying to highlight the difficulty of
reconciling the size of sauropods and the scaling of
their jaws/teeth with the known forage needs and
scaling of extant animals (as far as I know it hasn't
been done, love to be corrected if it has), as opposed
to commenting negatively on the hypothesis that
sauropods ate molluscs.

That said, if there is no coprolitic material
conceivably attributable to sauropods that contains
large quantities of (ground by gizzard stone?) mollusc
shell, then I don't think it is very robust.
