    Nice tyrannosaur tooth

    • Thank you! I found a nicer one 2 weeks ago. I’ll post a picture in the next week or two.

      • They are intresting because its kind a gray area whether they can actually be called tyrannosaur. This all depends on whether tyrannosaurs are defined as the tyrannosauridae or the larger group the tyrannosauroidea. Dryptosaurus was a tyrannosauroid, but not a tyrannosaurid. So very intresting

        • Dryptosaurus is Maastrictian. The location is Campanian. It is probably Appalachiosaurus.
