Nice, Serrated, 1.54" Nanotyrannus Tooth - Montana

This is a finely serrated, 1.54" long Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of Montana. Nice preservation on this tooth with great serrations on both edges and almost no feeding wear to the tip. The enamel is in fair condition with a few patches were it is missing. No repair.

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.
