Serrated, 1.57" Tyrannosaur (Nanotyrannus) Tooth - South Dakota

This is a serrated, 1.57" long Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of South Dakota. The enamel is in good shape and nearly all of the fine serrations are present. There is an interesting wear facet near the tip where it was rubbing against another tooth in the mouth. No repairs.

Comes with a floating frame display 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.
