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! :) :)

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).

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.

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? Thanks

There are some teeth that may be outliers but for most density is not a reliable method to differentiate Tyrannosaurids 

 

Distal density
