Partial skull and associated postcranial skeleton. Discovered in the Barremian Wealden Formation, in Surrey, England was a large reasonably complete skeleton of a previously unknown carnivorous dinosaur B.walkeri in some ways quite unlike other theropods. The teeth are strongly slightly recurved and rounded, not strongly compressed, in section. The snout is low and elongate, with a spatulate tip.A large manual claw inspired the media-given name "Claws". B.walkeri seems distinct from Becklespinax as there is no indication that B.walkeri had elongate dorsal neural spines. According to the Sereno ....Spinosauria Baryonychidae
