Serrated, 1.38" Tyrannosaur (Nanotyrannus) Tooth - Montana

 
This is a serrated, 1.38" long Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of Montana. It was collected this summer from a private quarry in Powder River County. There is some interesting feeding wear to the tip. The enamel is in pretty good shape with one wear spot on each side. Visible serrations along one edge. There is one repaired crack in the tooth.

Comes with a floating frame display 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.
