Baryonyx walkeri

Baryonyx is known from a partial skull and postcranial skeleton and is to date the most complete theropod found in England, it was discovered in a pit in Surrey, England, 1983. It was found by amateur palaeontologist William Walker. At least 70% of the specimen was recovered and is on display in the Natural History Museum, London. Its hands were equipped with a huge claw and its crocodile-like snout indicate it was probably a piscivorous animal. It is possible that the genera Suchomimus and Cristatusaurus are junior synonyms of Baryonyx. Suchosaurus cultridens from the Early Cretaceous of England, known from teeth is most probably the same animal than Baryonyx walkeri.
