Serrated, 1.02" Partial Tyrannosaur (Nanotyrannus) Tooth

This is a serrated, 1.02" long, partial Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of South Dakota. The tooth is broken off at the base. Many of the fine serrations are still present. Comes with a small acrylic case.

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.
