Miocene_Mason Posted June 19, 2017 Share Posted June 19, 2017 I acquired this tooth a while back from a seller who labeled this as daspletosaurus. He said it was collected in the Judith river formation. Is there any way to tell if this is correct? The Judith river formation according to Wikipedia has only two tyrannosaurs, deinodon and aublysodon (which is possibly a junior synonym of deinodon) so I'm guessing it's one of those? Any one know anything further? “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

MarcusFossils Posted June 19, 2017 Share Posted June 19, 2017 We'll need way better photos.. -Try a photo of the tooth from directly above -Try to photograph the edges of the tooth (so that any possible serrations are visible) Marc 1 Website: https://www.instagram.com/paleo_archives/ --------------------------------------------------------------------------- “It is by no means an irrational fancy that, in a future existence, we shall look upon what we think our present existence, as a dream.” ― Edgar Allan Poe Link to comment Share on other sites More sharing options...
Troodon Posted June 19, 2017 Share Posted June 19, 2017 Can you please post closer images of the tooth and straight in shots not at obtuse angles, Size? What is the locality where the tooth is from., county and State No Tyrannosaurid has been described from the Judith River Formation of Montana if that's were that tooth was found. Daspletosaurus and Gorgosaurus are the most likely candidates since they have been described from equivalent formations in Alberta. Aublysodon and Deinodon are not a valid taxons 1 Link to comment Share on other sites More sharing options...

Troodon Posted June 19, 2017 Share Posted June 19, 2017 Without a locality it's impossible to diagnose other than a tyrannosaurid Size? Unfortunately I dont trust formations provided by dealers without supporting localities. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted June 19, 2017 Author Share Posted June 19, 2017 I forgot so here's it next to a U.S. Dime: Ill see if I can find the seller again and try to get the locality... “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Well, you memory is a little shaky of when I bought this, and I couldn't find the seller but if my memory serves me right, I think it was from a ranch in north Montana “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Troodon Posted June 19, 2017 Share Posted June 19, 2017 Sounds like we won't have much more as far as locality other than northern Montana which is okay. I would ID your tooth as Tyrannosaurid indet. Getting much closer than that is impossible given the condition of your tooth, size and distinguishing between Gorgosaurus and Daspleto. teeth from that region is very difficult. In the future always ask for as much info on locality found as they can provide. 1 Link to comment Share on other sites More sharing options...

That's fine, I didn't buy it for too much anyway. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
