This is a solid, 4.7" long Hadrosaur (Hypacrosaur) caudal vertebra from the Two Medicine Formation of Montana. It was collected this summer and in still partially embedded in the hard sandstone that it was found in. There is some erosion around the edges but nothing has been repaired or restored.
About Hypacrosaurus
Hypacrosaurus is a very large, Lambeosaurini Hadrsosaur that would have been almost as large as the Tyrannosaurs that it lived alongside. Like Corythosaurus, it had a tall, hollow, rounded crest, although not as large and straight. It is known from the remains of two species that spanned 75 to 67 million years ago in the Late Cretaceous of Alberta, Canada, and Montana, United States, and is the latest hollow-crested duckbill known from good remains in North America. It is estimated to have been around 9.1 meters (30 feet) long and to have weighed up to 4-5 tons.
