Support: 70% (fragmentary condition, with most of the fragments present) Hadrosaurus is a genus of ornithopod dinosaurs that lived specifically in North America during the Late Cretaceous in the Woodbury Formation between 78 and 80 million years ago. The holotype specimen-that is, used to describe the species-was found in a riverine marine sedimentation, meaning that the animal's corpse was transported from a river into the sea. It was a large animal, 7 to 8 meters long, weighing 2 to 4 tons. Most of the preserved features are very robust traits: massive in build, hadrosaurs were equipped with keratinous beaks for cutting foliage and specialized and complex teeth for processing food. Hadrosaurs laid in nests capable of holding even more than a dozen eggs.
