Serrated, .80" Tyrannosaur (Nanotyrannus?) Tooth - South Dakota

This is a .80" long Tyrannosaur tooth likely of the species Nanotyrannus lancensis from the Hell Creek Formation of Harding County, South Dakota. The preservation is excellent on this tooth.

Comes with an acrylic display case.

There is a very contentious debate among paleontologists about whether Nanotyrannus and Tyrannosaurus rex (T-Rex) are really the same species, with Nanotyrannus representing juveniles. Papers going back on forth on the topic continue to be published and there is a lot of fossil evidence under study which has yet to be published. We tend to fall into the camp that Nanotyrannus is in fact a separate species.

Nano teeth tend to be much more finely serrated, and much thinner/blade like t-rex teeth, in addition to being smaller. Though given the state of the debate labeling them as juvenile t-rex teeth would be just as valid.
