6.4" Fossil Hadrosaur Anterior Caudal Vertebra - Montana
This 6.4" wide anterior caudal vertebra centrum was collected from the Late Cretaceous-aged Two Medicine Formation in Montana. There are multiple species of hadrosaurs in the Two Medicine Formation, so identifying an isolated bone such as this is difficult. However, based on abundance, this likely came from Hypacrosaurus stebingeri or Maiasaura peeblesorum.
Comes with an acrylic display stand.
The base of both transverse processes and pedicles are still present. There is a repaired crack across the middle of the centrum, requiring some gap fill restoration, with a larger section of gap fill where the crack ends along the edge of bone. Restoration on this specimen makes up less than 5% of the vertebra.

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.
