9.25" Theropod (Raptor) Tibia with Metal Stand - Montana
This is a fossil tibia of a theropod (raptor) dinosaur. It was collected this past year from our partner's private quarry on the Two Medicine Formation in Pondera County, Montana. Often isolated bones are very difficult to ID to a specific genus and that is the case with this one.
The bone measures 9.25" long and stands 9.8" tall on the included custom metal display stand. There are two repaired cracks through the diaphysis of the bone that required gap fill restoration. Both epiphyses are weathered.

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.
