Iguanacolossus is an ornithopod dinosaur from the Early Cretaceous of the United States of America. It was named in 2010 by Andrew T. McDonald and his crew. It was one of the many iguanodontians that roamed North America, and was discovered alongside Hippodraco.


Iguanacolossus was a quadrupedal ornithopod with a bulky body, long forelimbs, long, muscular hindlimbs, a moderately long tail, and a large head with a small beak in front of its mouth. Its body would have been covered in scaly skin.


Iguanacolossus was an herbivore, feeding on leaves, horsetails, cycads, and conifers. Its round beak was used to strip leaves off branches, while the many teeth in the back of its mouth would grind together, processing the leaves.
