1.81" Serrated, Tyrannosaur Tooth - Judith River Formation

Serrated, Tyrannosaur Tooth - Judith River Formation #128511

This is a 1.81" long Tyrannosaur tooth on stone, 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. The tooth is in excellent conditions with good enamel and fine serrations along both edges of the blade. There is a little bit of the original rock attached to the base of the tooth and only some minor feeding wear to the tip.

Comes with a floating frame display case.

Three species of tyrannosaur have been described from the Two Medicine & Judith River Formations: 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.
