19" Killer Tyrannosaur (Daspletosaurus?) Metatarsal - Montana

This is a gorgeous, 19" long Tyrannosaur (Daspletosaurus sp.?) metatarsal from the Two Medicine Formation of Montana. It was collected this last summer from our partner's private lease and has been nicely prepared from the hard rock surrounding it. It would have come from the left leg of the Tyrannosaur and is the II metatarsal. The sheer size of this foot bone is mind boggling!

It has very little restoration (outlined below) and sits beautifully on the included custom metal display stand.

The bone was found with significant fragmentation of the diaphysis, requiring crack repair, glue stabilization, and gap fill restoration in spots. Both epiphyses have undergone some weathering and have some areas of restoration. The proximal epiphysis has restoration along the anterior and posterior points of articulation, and the distal epiphysis has a repaired crack through it with some gap fill restoration.

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.
