Diet & Feeding

Piscivore

Baryonyx was a fish-eating dinosaur. Piscivores typically lived near water sources and had specialized adaptations such as elongated snouts and conical teeth for catching fish.

Time Period

Cretaceous Early Mesozoic Era

Baryonyx lived during the Cretaceous Early period of the Mesozoic Era, approximately 145.0 to 100.5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
