While never becoming the wastebasket taxon several other early genera of dinosaurs became ( such as Megalosaurus ) , Iguanodon has had a complicated history , and its taxonomy continues to undergo revisions . Although Gregory Paul recommended restricting I. bernissartensis to the famous sample from Bernissart , ornithopod workers like Norman and McDonald have disagreed with Paul 's recommendations , except exercising caution when accepting records of Iguanodon from France and Spain as valid .
