Thick 2.19" Tyrannosaur Tooth In Matrix - Montana
This is thick Tyrannosaur tooth from the Two Medicine Formation (Judith River Group) of Montana. The tooth is 2.19" long, has good enamel preservation, and very feeding wear to the tip. The serrations that are exposed are in good shape but many are still under the rock. Since most of the teeth we get are already free of most of the matrix we decided to leave this one in the rock. We can remove it for the buyer upon request from the buyer, though. We have just removed some more matrix around the tooth and there was no repair or restoration done.
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
Another interesting tidbit is that all of the matrix on the bones and teeth we recently received from Two Medicine Formation (Judith River Group) are packed full of fossil clam shells. That section of the formation in Montana obviously represented some type of shoreline environment. There is a fossil gastropod on the back of the specimen.
