Serrated, 1.81" Tyrannosaur Tooth in Rock - Montana

 
 
 
This is a 1.81" Tyrannosaur tooth in rock that was collected from the Two Medicine Formation of Montana. The tooth is still in the rock that it was found in. There are some natural stress fractures that run both along and across the length of the tooth. The serrations are still present, though the exposed serrations have multiple chips missing. The tip of the tooth is still in excellent condition and smaller portions of this rock have been glued back to the largest section to ensure stability of the tooth..

This specimen comes with an acrylic display stand.

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.

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.
