CollectA Iguanodon Basal, or non-hadrosaurid, members of Iguanodontia are among the most widespread, diverse, and numerous dinosaurs in Early Cretaceous terrestrial deposits. Camptosaurus depressus and Dakotadon lakotaensis , Tenontosaurus, Hippodraco and Iguanacolossus basal iguanodonts from the Barremian–Aptian of western North America are more basal than contemporaneous taxa from Europe and Asia. Basal iguanodontian dinosaurs were extremely successful animals, found in great abundance and diversity almost worldwide during the Early Cretaceous.
