9.5" Hadrosaur (Hypacrosaur) Metatarsal with Metal Stand - Montana

This is a really cool, 9.5" long Hadrosaur (Hypacrosaurus sp.) metatarsal (foot bone) from the Two Medicine Formation of Montana. It was collected this last summer and has been nicely prepared from the hard rock surrounding it. There is a repaired crack through the diaphysis and one through the distal epiphysis, each of which required some gap fill restoration. There is also some restoration to the proximal end of this bone where it would have articulated with the fibula/tibia.

Comes with the pictured custom 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.
