Serrated, 1.34" Tyrannosaur (Nanotyrannus) Tooth - South Dakota

This is a serrated, 1.34" long Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of South Dakota. This tooth is in excellent condition, with no indication of any repair or restoration! One of the serrated edges looks to have undergone some chipping and/or feeding damage, while the opposite edge only contains minor chipping.

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.
