5.1" Hadrosaur (Hypacrosaur?) Cervical Vertebra - Montana
This is an awesome, 5.1" wide Hadrosaur (Hypacrosaurus sp.?) cervical vertebra centrum from the Two Medicine Formation of Montana. It was collected this last summer and has been nicely prepared from the hard rock surrounding it. The fragile processes of this vertebra have weathered away, along with the edges of the body. There is only one spot of repair where the bone was found separated from the vertebra, requiring some gap fill restoration. This can be found on the left-anterior side of the vertebra.
It comes with an acrylic display stand.

About Hypacrosaurus
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.

About The Two Medicine Formation
The Two Medicine Formation is a geographical formation in Central Montana and Southern Alberta, Canada. The formation is predominantly sandstone laid down by rivers and deltas during the Campanian Age of the Cretaceous, about 80-75 million years ago. Approximately two thousand feet thick on the western edge, it lies on top of the Virgelle Sandstone formation and under the Bearpaw Shale. It is located between the Front Range of the Rocky Mountains and the Sweetgrass Arch, a tectonic fold feature 40-90 miles east of the Front Range.
The Two Medicine is the same age as the Judith River Formation found further east. It was laid down further inland from the Western Interior Seaway, while the Judith River Formation was deposited along the coast. The Two Medicine contains much of the same dinosaur fauna, but fewer reptiles, amphibians, and aquatic fossils.
