Top Quality 1.69" Tyrannosaur Tooth - Montana
This is top quality Tyrannosaurid tooth from the Two Medicine Formation (Judith River Group) 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.
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. I've linked to the research paper below.
Morphometry of the teeth of western North American tyrannosaurids and its applicability to quantitative classification
This tooth is 1.69" long and is spectacular. It has beautiful light colored enamel, minimal feeding wear and NEARLY PERFECT SERRATIONS. There are a few crack repairs where the tooth was glued back together, and a small gap fill on one side in the middle of the tooth. The last photo in the series highlights where this gap fill is.
