.80" Partial Tyrannosaur (Nanotyrannus) Tooth - Montana

This is a .80" long, partial Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of Montana. The tip of the tooth is broken off or it would have been about 1 1/2" long. Nice enamel preservation with visible serrations.

Comes in a small acrylic bubble 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.
