1.08" Tyrannosaur Premax Tooth - Judith River Formation, Montana

This is a 1.08" Tyrannosaur premaxillary tooth from the Judith River Formation of Montana. This formation is approximately 70 million years old, or about 5 million years older than the Hell Creek Formation which produces T-Rex.

The enamel is chipped proximal to the root, there is some damage/wearing to the tip and there are two repaired cracks through the tooth, one at the tip and one through the middle.

There are three described Tyrannosaurs from the Two Medicine Formation & Judith River Formation, 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.
