This is a 1.78" Tyrannosaur tooth from the Judith River Formation 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 some interesting feeding wear to the tip of the tooth. About half of the serrations are present on the inner edge, but the rest are worn. There are couple of repaired cracks with small gap fills near the base of the tooth. Comes with a riker mount display case.
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.
