Valdosaurus

Galton 1977

Valdosaurus is a genus of bipedal herbivorous dryosaurid dinosaur known from the Early Cretaceous of the Isle of Wight and elsewhere in England. Originally its remains were believed to belong to Hypsilophodon. In 1889, Richard Lydekker assigned them to Camptosaurus, alongside a partial lower jaw, and applied the name Camptosaurus valdensis. In the 1970s, Peter Galton reassigned these remains to a new species of Dryosaurus, then to an entirely new genus and species, that being Valdosaurus proper. The type and only species of Valdosaurus, named by Galton, is V. canaliculatus.
