seen as a nothosaur,
Simosaurus was a marine reptile that lived in
European waters during the Triassic. The teeth of Simosaurus
quite blunt and while the jaws of Simosaurus are
quite gracile, the
way the muscles attached show that they could be closed very quickly.
It is possible that Simosaurus used quick but
bites to crack up the shells of invertebrates like ammonites,
especially those with thinner shells.
