       Although the name means lizard,‭ ‬Steneosaurus was actually a crocodile.‭ ‬It is believed that Steneosaurus lived in coastal waters where it could hunt for animals like fish as well as possibly other small marine organisms.‭ ‬The broad geographical and temporal range combined with the remains of well over fifty individuals‭ ‬indicates that Steneosaurus was a very successful genus of crocodile.
