(PhysOrg.com) -- Paleontologists from the University of Pennsylvania and the Utah Geological Survey have described two skeletons representing two new species of beaked herbivorous dinosaurs, known as iguanodonts, from Utah. The new dinosaurs were preserved in rocks dating to the Early Cretaceous Epoch, ~145.5 99.6 million years ago. The new specimens help illuminate the natural history of North American iguanodonts.
