Thick, 2.21" Tyrannosaur Tooth - Montana

This is a robust, 2.21" Tyrannosaur tooth from the Two Medicine Formation (Judith River Group) 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.

There is an interesting wear facet to the tip where the tooth was rubbing against other teeth in the jaw. The tooth is nice and thick, with most of the serrations visible on the inner edge. The enamel is bleached by exposure to the elements in many areas. There are a few crack repairs and some very minor gap filling.

There are three described Tyrannosaurs from the Two Medicine Formation (Judith River Group), 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.
