Serrated, .75" Tyrannosaur (Nanotyrannus) Tooth - South Dakota

This is a serrated, .75" long Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of South Dakota. The enamel is worn in areas, primarily on one face of the tooth. There is feeding wear that runs up the edges of the tooth, as well as wearing of the tip. Proximal to the root location is some glue, indicating there is a repaired crack.

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.
