12.2" Raptor (Dromaeosaur) Metatarsal with Metal Stand - Montana
This is a fossil metatarsal bone of a theropod dinosaur, from the Two Medicine Formation of Pondera County, Montana. Using size as an indictor it is most likely that this bone is from Dromaeosaur. The bone measures 12.2" long and stands 12.8" tall on the included custom metal display stand.
There are several repaired cracks through the diaphysis of this bone where it was found fragmented within the rock, with spots of gap fill restoration where missing bone fragments left gaps. Both the proximal and distal ends underwent some weathering, both of which required restoration. The bend at the distal end of the bone is natural and indicates that this would have been the lateral metatarsal on the left leg.

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.
