Tylosaurus cf. proriger

Tylosaurus cf. proriger

Campanian

Texas

Ozan fm Tylosaur tooth found in gravel. I'm of the opinion that perhaps the assignment of T. proriger to the Ozan Tylosaurs is hasty - though it's difficult since the obvious differences between these and the holotype are restricted to a single cranial element. Not sure I should say much more on that - while it's not an existing research question it's not my original observation.
