TYRANNOSAUR TEETH - TWO MEDICINE/JUDITH RIVER FOR SALE
The Two Medicine and Judith River Formations outcrop in Northern Montana and contains three Tyrannosaurs, Albertosaurus, Gorgosaurus, and Daspletosaurus. These formations are about 5 million years older than the Hell Creek Formation which is home to T-Rex. Daspletosaurus the largest of the Tyrannosaurs in this formation is thought by some paleontologists to be a direct ancestor of T-Rex. The teeth of these three Tyrannosaurs are so similar that it's statistically impossible to assign isolated teeth to one of the genus' except in the case of the largest teeth which could only have come from Daspletosaurus.
