Baryonyx

Islandwalk, Devour
In 1997, Charig and Milner demonstrated direct dietary evidence in the stomach region of the B. walkeri. It contained the first evidence of piscivory in a theropod dinosaur, acid-etched scales and teeth of the fish Scheenstia mantelli, and abraded bones of a young Iguanodon. A gastrolith (gizzard stone) was also found.
