1.5" Serrated Tyrannosaur Tooth - Judith River Formation

This is a serrated, 1.5" long Tyrannosaur tooth from the Judith River Formation of Montana. This formation is approximately 75 million years old, or about 9 million years older than the Hell Creek Formation which also produces T. rex.

There enamel and serrations are chipped in spots and there is a repaired crack towards the tip of the tooth that required some gap fill restoration. There is feeding wear that runs up one side of the tooth.


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 genus because they are so similar.
