Large, 1.67" Nanotyrannus Tooth - Montana

This is a large, 1.67" long Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of Montana. The tooth has a mottled coloration, brown on the upper half to yellowish on the lower half. This is possibly due to the tooth being partially digested either by a predator or the animal itself. The tip is good and while the serrations are worn, most are still visible.

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.
