TheItalianPaleo Posted February 11, 2021 Share Posted February 11, 2021 Hi everyone, So I came across a tooth that says this tooth comes from a carnivore (Gorgosaur/Daspletosaur), is 3.81 cm in length. The seller is a Daspletosaurus, but you know, before buying anything I have to ask your opinion. It was found in the Two Medicine Formation. There was a debate as to whether it was either a Gorgosaurus or a Daspletosaurus. So the questions are: Is it a Daspletosaurus or a Gorgosaurus? In what condition it is? 1 Link to comment Share on other sites More sharing options...
Troodon Posted February 11, 2021 Share Posted February 11, 2021 Do you have a location need State and County where it was found to verify its from the Two Medicine Fm 1 Link to comment Share on other sites More sharing options...
Runner64 Posted February 11, 2021 Share Posted February 11, 2021 Really hard to tell the difference between Daspletosaurus and Gorgosaurus teeth. I don’t think you’ll be able to tell a difference with this tooth. 1 Link to comment Share on other sites More sharing options...

Troodon Posted February 11, 2021 Share Posted February 11, 2021 That is not a adequate locality. There are numerous formations in Northern Montana of different ages and dinosaurs. I typically need the County or nearest town it was found in.. The preservation (color) is more typical of what you see in the Judith River Formation. Having said that this tooth it's a indeterminate Tyrannosaurid. It's very difficult to distinguish between Daspletosaurus and Gorgosaurus teeth especially one that has poor serration preservation. For your budget this is a nice tooth and it's very acceptable to call it an indeterminate Tyrannosaurid 2 Link to comment Share on other sites More sharing options...

dinosaur man Posted February 11, 2021 Share Posted February 11, 2021 There doesn’t seem to be any signs of enamel wrinkles, so we can’t use them to identify what it is. May I ask what the serration count is over 2 mm on both sides? And like @Troodon said the locality will also be needed. Link to comment Share on other sites More sharing options...
TheItalianPaleo Posted February 11, 2021 Author Share Posted February 11, 2021 The seller didn’t specified the formation. But I think is a very good tooth 1 Link to comment Share on other sites More sharing options...

-Andy- Posted February 14, 2021 Share Posted February 14, 2021 As Frank said, it's a tyrannosauridae indet. If you dislike writing that though, you could label it as Daspletosaurus/Gorgosaurus sp. That aside, the preservation color looks more like JRF than Two Medicine to me Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday! Link to comment Share on other sites More sharing options...
