Rikache Posted January 5, 2022 Share Posted January 5, 2022 Hi there everyone! I've recently been adding specimens to my collection and I came across a listing advertising a juvenile tyrannosaur / nanotyrannus tooth coming from the Hell Creek formation in Montana. The seller is very reputable thus I have no doubt that the specimen itself is truly a fossil. Instead, I was wondering if anyone could help me positively identify the specimen as being from a juvenile tyrannosaur / nanotyrannus (depending on which camp you come from). Thank you!

hadrosauridae Posted January 5, 2022 Share Posted January 5, 2022 The base profile is the key. You see how its a roughly rectangular shape with a slight pinch to the long sides? Those are the hallmarks for a nanotyrannus tooth. 1 "There is no shortage of fossils.

Troodon Posted January 5, 2022 Share Posted January 5, 2022 Do you have a locality where this tooth was found? Can I see a better photo of the base without fingers. FYI most sellers are reputable however identification of dinosaur material is not their strong point 1 Link to comment Share on other sites More sharing options...

I spoke with the seller and he said he found the tooth while fossil hunting in the Hell Creek Formation in Montana but no more specific locality was given.

Troodon Posted January 5, 2022 Share Posted January 5, 2022 Unfortunately thats not a locality I can determine if its indeed the Hell Creek Fm. Need a better photo of the base and locality otherwise and its all guesswork and an indeterminate tyrannosaurid. PS if your seller collected it he should be able to provide you a County 1 1 Link to comment Share on other sites More sharing options...

I'll more than likely make the purchase nevertheless so I'll quote you on more photos once it arrives to possibly obtain a more accurate identification.

Troodon Posted January 5, 2022 Share Posted January 5, 2022 A locality is the most important requirement when trying to identify isolated theropod teeth. Montana has many adjacent formations with different dinosaurs. If its HC we really need to see if the pinch in the base is on one side or both with Nanotyrannus teeth its the latter. Hard to determine from the photo provided 4 Link to comment Share on other sites More sharing options...

Back with an update on the tooth. I finally received the specimen in the mail and was able to take some better photos of the base. The first two photos show the tooth's base with the serrations facing the left. The third and last photo shows the base of the tooth with the serrations facing to the right. Let me know if you need any more photos and thank you! Link to comment Share on other sites More sharing options...
