Superb 2.02" Tyrannosaur Tooth - Montana

This is a 2.02" 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.

This tooth has beautiful enamel, sharp serrations, and some feeding wear to the tip. There is one crack repair and minimal restoration to fill in gaps around the break and some longitudinal gaps left from the fossilization process. This helps to stabilize the fossil.

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.
