Serrated, 1.72" Tyrannosaur Tooth - Montana

This is a serrated 1.72" Tyrannosaur tooth that was collected from the Two Medicine Formation of Montana. There is a repaired crack about a half inch down from the tip and one proximal to the root. The enamel is weathered and chipped. Serrations are present along both edges of the tooth, however they have undergone some chipping.

Comes with a floating frame display case.

There are three described Tyrannosaurs from the Two Medicine Formation & Judith River Formation, Albertosaurus, Gorgosaurus and Daspletosaurus. Research done on teeth from these three Tyrannosaurs has concluded that isolated teeth are statistically impossible to assign to a specific genre because they are so similar.

Morphometry of the teeth of western North American tyrannosaurids and its applicability to quantitative classification

The Two Medicine Formation is a geographical formation in Central Montana and Southcentral Alberta, Canada and is named for the Two Medicine River in Montana. 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. It is analogous to the Judith River Formation but remains a separate feature.
