Good Quality 1.69" Tyrannosaur Tooth - Montana

This is a 1.69" 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 that is slightly weathered, sharp serrations on the posterior edge and dulled serrations on the anterior edge, and the tip has a tiny amount of feeding wear. There are no crack repairs but there is a small amount of restoration to fill gaps and to stabilize the fossil near the root.

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.
