However Tyrannosaurid fossils from Judith River aren't technically diagnostic to genus due to incomplete remains. Generally teeth are labeled as either Gorgosaurus/Albertosaurus libratus or Daspletosaurus sp. Yes, this is something that is quite sceptical to me. Strictly speaking, I should label them as Tyrannosaur indet. I have just been passive and labelled them up what the seller has described them as. I think it is only Daspletosaurus teeth that are easier to distinguish and even that, I have scratched my head quite a few times now. I am well affiliated with two amateur paleontologists, one digging at the Two-Med and one at the Judith river. Both are well researched and have access to university materials, lecturers and researchers and yet they still cannot confirm all the teeth (with absolute clarity) that they pull from their respective sites.

Generally teeth are labeled as either Gorgosaurus/Albertosaurus libratus or Daspletosaurus sp. My understanding, there are no Tyrannosaurids described from the Judith River Formation. Albertosaurus is only known from very late Campanian/younger Maastrichtian deposits typical of the Horseshoe Canyon Formation. This morphology fits like you say Daspletosaurus sp or Gorgosaurus sp. 1 hour ago, Mail1989 said: Pterosaur wing claw, Kem-Kem beds, Morocco We had a discussion on this type of specimen a while back. Although typically sold as a pterosaur claw its fish. The morphology does not fit any known pterosaur claws. 3 Link to comment Share on other sites More sharing options...

I agree does not look like an Abelisaurid and would lean toward an anterior tooth of an undescribed Carcharodontosaurid Link to comment Share on other sites More sharing options...
