Serrated, 1.95" Tyrannosaur Tooth - Judith River Formation, Montana

This is a 1.95" long Tyrannosaur tooth from the Judith River Formation of Montana. This formation is approximately 70 million years old, or about 5 million years old than the Hell Creek Formation which produces T-Rex. Comes with a floating frame display case.

The serrations along one edge of the tooth remained in great condition, though there is a section which chipped away proximal to the root. There is are two repaired cracks through the middle of the tooth, as well as some gap filled cracks. One faces of the tooth contains many cracks as a result of geologic forces that slightly deformed the tooth. The tip has undergone some feeding wear.

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.
