Hadrosaur (Hypacrosaur) Humerus - Montana #113401

This is an exceptionally well preserved, 19.4" long Hadrosaur (Hypacrosaur) humerus (upper arm bone) from the Two Medicine Formation Montana. This humerus is from the left arm (front leg). The bone is in very good condition with almost no erosion and just some minor repairs and gap fill restoration in the repaired cracks.

Comes with the pictured metal display stand.

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.
