Bargain, 1.18" Tyrannosaur Tooth - Montana

This is a 1.18" 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.

About half of the serrations are present and there is minimal feeding wear to the tip. There are a couple repaired cracks in the tooth with gap fills, hence the reduced price.

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.
