Comptonatus

Comptonatus is an iguanodontid ornithopod dinosaur that lived about 125 million years ago, in the Early Cretaceous of what is now Europe. It was a medium sized herbivore at about 7 m in length, and weighed around 1 t in body mass. Fossilized footprints found near the original specimen indicate that Comptonatus was likely a herding animal. Comparisons between Comptonatus and other iguanodontids that lived around the same time and region show a high rate of diversity. This indicates there may have been pressure for speedy evolutionary adaptation in the region, or perhaps a high volume of migration.
