 Iguanodon gives its name to the unranked clade Iguanodontia , a very populous group of ornithopods with many species known from the Middle Jurassic to the Late Cretaceous . Aside from Iguanodon , the best @-@ known members of the clade include Dryosaurus , Camptosaurus , Ouranosaurus , and the duck @-@ bills , or hadrosaurs . In older sources , Iguanodontidae was shown as a distinct family . This family traditionally has been something of a wastebasket taxon , including ornithopods that were neither hypsilophodontids or hadrosaurids . In practice , animals like Callovosaurus , Camptosaurus , Craspedodon , Kangnasaurus , Mochlodon , Muttaburrasaurus , Ouranosaurus , and Probactrosaurus were usually assigned to this family .
