About this image:
Deinosuchus was a large alligator-like animal from the Cretaceous, whose head was six feet or more in length. The shape and proportion of Deinosuchus' head makes scientists believe it was adept at catching animals both under water and at water's edge. Its fossilized remains have been found both in saltwater and freshwater deposits.
