TYRANNOSAUR TEETH - HELL CREEK FORMATION FOR SALE
The Hell Creek Formation which is exposed in Montana and South Dakota was the home of two Tyrannosaurs, Tyrannosaurus rex (T-Rex) and Nanotyrannus lancensis. There are some paleontologist that believe Nanotyrannus is not a distinct species and represents a juvenile T-Rex. Recent fossil finds in the process of publication due point to them being distinct species, though.
