gigantoraptor Posted April 11, 2019 Share Posted April 11, 2019 I assume this tooth is from the Hell Creek Formation? It's not possible to tell Nanotyrannus and Dakotaraptor teeth apart by just pictures. We need a density count on both sides and we need to know both lenght and width of the base so we can see how compressed it is. Dakotaraptor teeth are rare. 1 Link to comment Share on other sites More sharing options...

fossilsonwheels Posted April 11, 2019 Share Posted April 11, 2019 I am pretty sure I have seen this tooth posted on the forum before. If it is the one I am thinking of, there are no serrations on one side of it which would make verification on the ID impossible. I could be wrong but it looks like that tooth. 1 Link to comment Share on other sites More sharing options...

Troodon Posted April 11, 2019 Share Posted April 11, 2019 One characteristic that can quickly determine if NOT a Dakotaraptor tooth is the shape of the mesial carina. Dakotaraptor crowns have a straight carina that extends ends 1/3 from the base. This tooth has a mesial carina with a slight lingual twist, visible on the other post, that is typical of SOME Nanotyrannus teeth depending on jaw position. So it tells us its not Dakotaraptor 3 Link to comment Share on other sites More sharing options...
