1.35" Juvenile Hadrosaur (Hypacrosaurus) Vertebra - Montana
This is a 1.35" tall, caudal vertebra of a juvenile Hadrosaur (Hypacrosaurus). It was collected this past summer from the Two Medicine Formation of Pondera County, Montana. Comes with a floating frame display case.
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.
