JoeS Posted July 25, 2020 Share Posted July 25, 2020 Hi all, I could not resist and purchased this tooth knowing it would be a tough call to make. It was found in the Hell Creek Fm. The big problem is the worn down mesial carina, there are however some remnant denticles I could measure, but not midline – more posterior. Taking them into consideration the tooth has distal 4.5 denticles per mm and mesial 6 per mm. The other measurements are: CH 1.47 cm / CBL 0.74 cm / CBW 0.39 cm. Based on this and the oval base I am leaning towards Dakotaraptor but might as well be a specific T-Rex tooth position.? I really need someone more experienced to take a look please. Any help is highly appreciated. Link to comment Share on other sites More sharing options...

Troodon Posted July 25, 2020 Share Posted July 25, 2020 Well then you really don't know if its Hell Creek. Any assignments is just a guess. Link to comment Share on other sites More sharing options...

Troodon Posted July 25, 2020 Share Posted July 25, 2020 Its just good practice to get a good solid provenance on dinosaur material from Montana. I dont trust sellers. Took a look at the tooth and assuming its HC I believe its a Tyrannosaurid tooth. Denticle shape, Twist in Carina and Crown height ratio does not fit Dakotaraptor 2 Link to comment Share on other sites More sharing options...
JoeS Posted July 25, 2020 Author Share Posted July 25, 2020 Thank you Troodon. I'll see if I can get a more precise location from the seller. Link to comment Share on other sites More sharing options...
