Dark, 1.20" Tyrannosaur (Nanotyrannus) Tooth - Montana

This is a serrated, 1.20" long Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of Montana. Really dark enamel preservation, almost to a black coloration. The inner serrations are mostly present. Some minor feeding damage to the tip. No repairs.

There is a hot debate among paleontologists about whether Nanotyrannus and Tyrannosaurus rex (T-Rex) are really the same species, with Nanotyrannus representing juveniles. Recent finds that are soon to be published should put this debate to rest, definitively proving that Nanotyrannus is in fact a separate genus and valid genus. Nano teeth tend to be much more finely serrated, and much thinner/blade like t-rex teeth, in addition to being smaller.
