3.4" Hadrosaur (Hypacrosaurus?) Toe Bone - Montana

Hadrosaur (Hypacrosaurus?) Toe Bone - Montana #145171

This is a 3.4" wide Hadrosaur (Hypacrosaurus sp.?) phalange (toe bone) that was collected from the Two Medicine Formation of Montana. It was collected this spring and is still in great condition. The cortical bone has weathered away from some of this bone, revealing the mineral formations within the bone matrix. There are some natural fractures through this bone that have been stabilized with glue. Other than the glue stabilization, there is no additional repair or restoration to this bone.

It sits nicely on the provided 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.
