Well Preserved 1.60" Tyrannosaur Tooth - Montana

This is a nicely preserved 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

This tooth is 1.60" long, very wide and is in beautiful shape with good enamel preservation and most of the serrations intact. There are a few interesting wear spots on the tooth where it was rubbing against another tooth in the dinosaurs mouth. There small crack was filled near the base of the tooth, but it was such as small repair it's barely worth mentioning.
