In 2009 however, Galton critically reviewed the "Valdosaurus" material. He concluded that no fossils from outside England could be reliably referred to the genus. He thus gave "V. nigeriensis" its own genus: "Elrhazosaurus". Even of many of the English specimens it was uncertain whether they belonged to "Valdosaurus", including all cranial elements and teeth. Some hindlimb and pelvis bones from the Upper Weald Clay Formation (late Barremian) were referable to "V. canaliculatus". Some material from the earlier Hastings Beds (Valanginian) were referred to a "Valdosaurus" sp. Galton established that Richard Owen had in 1842 been the first to describe "Valdosaurus" thighbones, specimens BMB 004297-004300, assigning them to "Iguanodon". Galton emphasized that though the type femora were very small, fourteen centimetres long (which has led to estimates of a length of 1.2 metres and a weight of ten kilograms), these were from a juvenile individual and that an adult would have been a "medium-sized euornithopod", with some thighbones reaching a length of half a metre.
