2.8" Fossil Hadrosaur Toe Bone - Montana
This is a 2.8" wide Hadrosaur 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 preservation detail is excellent with some minor weathering along the edges and a chip along the proximal-ventral edge of the bone. There is no repair or restoration to this specimen.
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.
