       Iguanacolossus acquired its name from its similarity to another dinosaur named Iguanodon.‭ ‬Although Iguanacolossus might not actually have been any bigger than the largest examples of Iguanodon,‭ ‬it might still have been the largest ornithopod plant eating dinosaur alive in North America at this stage of the Cretaceous,‭ ‬with the only plant‭ ‬eaters larger than this being the sauropods.
