1.37" Tyrannosaur Tooth - Fine Serrations

 
This is a well preserved, 1.37" Tyrannosaurid 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 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. I've linked to the research paper below.

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

The tooth has good enamel preservation and fine serrations along both edges. There is very little wear to the tip and only a single repaired crack with no restoration.
