Abstraktum Posted January 6, 2019 Share Posted January 6, 2019 Hello everybody So this tooth here is up for sale. Described as a Daspletosaurus tooth from the Judith River Formation. (Not more information) Length: 5,3 cm or around 2 inches. There seems to be some crack repair on the tip but other then that it looks good to me. What I wondering is, if it's possible to describe this as a Daspletosaurus tooth? Or are there just to few information for a proper identification? Any help on what I am looking at is very welcome. Thank you! 1 Link to comment Share on other sites More sharing options...
Anomotodon Posted January 6, 2019 Share Posted January 6, 2019 Tyrannosaur teeth from Campanian deposits (Judith river, Two medicine, some Canadian formations) cannot be identified beyond Tyrannosauridae indet. There were at least 2 genera in that time period - Daspletosaurus and Gorgosaurus and their teeth are practically identical (in case of Judith river - no tyrannosaurs were formally described from there although Gorgosaurus and Daspletosaurus are known from Canada and Montana at that time). 7 The Tooth Fairy Link to comment Share on other sites More sharing options...
TyBoy Posted January 6, 2019 Share Posted January 6, 2019 Agreed it's Tyrannosaurid indet. Could also be a Gorgosaurus. 1 Link to comment Share on other sites More sharing options...

LordTrilobite Posted January 6, 2019 Share Posted January 6, 2019 As far as I know Daspletosaurus did get larger than Gorgosaurus and thus some larger tooth can be identified if they are over the size Gorgosaurus got to. 2 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

How would I go about doing this for a tooth of the 3 inch size? Anything I can do with serration counts? Also @Troodon do you know any way?

Troodon Posted August 26, 2019 Share Posted August 26, 2019 There are some teeth that may be outliers but for most density is not a reliable method to differentiate Tyrannosaurids Distal density 2 Link to comment Share on other sites More sharing options...
