Baryonyx

Baryonyx (meaning "heavy claw") is a genus of carnivorous saurischian dinosaur first discovered in clay pits just south of Dorking, England, and later reported from fossils found in northern Spain and Portugal. It is known to contain only one species, Baryonyx walkeri. Its fossils have been recovered from formations dating from the Hauterivian to early Barremian stages of the early Cretaceous Period, around 130–125 million years ago.

Baryonyx is one of the few known pisci vorous (fish-eating) dinosaurs, with specialized adaptations like a long low snout with narrow jaws filled with finely serrated teeth and gaff-hook-like claws to help it hunt its main prey.
