This is a huge, 3.01" Tyrannosaur tooth from the Two Medicine 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.
This large, robust tooth Tyrannosaur tooth with good enamel preservation. There is very little tip where and many of the serrations are present. There are several repaired cracks with gap fills in 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. Due to the size of this tooth it makes Daspletosaurus the most likely candidate as it's the largest of the three Tyrannosaurs.
