In the late nineteenth century, The Reverend William Darwin Fox collected two small thighbones close to Cowleaze Chine on the southwest coast of the Isle of Wight. In 1868, he erroneously suggested that they might have been from the same person that was discovered in 1848 by Gideon Mantell as a fossil of Iguanodon and was later named in 1869 as the new Genus Hypsilophodon. However, both femora included in collections of the British Museum of Natural History as specimens BMNH R184 and BMNH R185 and BMNH R185, are typically referred to as belonging to the latter Genus.

In 1975, Peter Galton named them as an entirely novel species in Dryosaurus: Dryosaurus canaliculatus. The name translates to “with a small channel” in Latin meaning a distinct groove between condyles in the lower portion of the thighbone. In 1977, Galton named the new genus: Valdosaurus, the name coming of Latin Valdus, “Wealden” and a reference to the Wealden Group. The species that is its type, D. canaliculatus, was therefore changed to V. canaliculatus. Another specie, V. Nigeriensis was discovered by Galton and Philippe Taquet from younger rocks from Niger in 1982. This is now moved into its own genus, Elrhazosaurus.

In 1998, William Blows inadvertently named another species, Valdosaurus dextrapoda, by adding this name to the list of fauna, however it was an error which is why the species has not been confirmed. In the absence of a description, it’s an unspecified nomen nudum.
