Sea-going crocs (thalatosaurs, metriorhynchids and dyrosaurs) all had long
thin snouts that, in modern crocs, is associated with fish-eating. However,
this could also provide greater manouvrability of the snout underwater.
 From memory there is a paper on the stomach contents of a metriorhynchid
and that proved to be ammonoids.
