Sergiorex Posted September 7, 2022 Share Posted September 7, 2022 Hello I was looking at a few teeth and wanted help with identifcation First one I’m almost certain is a tyrannosaurid, even though it’s in horrible condition and am leaning towards Tyrannosaurus Rex due to robustness and no pinch. it comes from Garfield county, hell creek form and measures .6 inch. Second one is also likely a tyrannosaurid, im leaning towards Nanotyrannus but it’s probably a indeterminate tyrannosaurid. It’s from hell creek form, no locality unfortunately. Size is about 1 3/8 by 1/2 inch. 3rd one seems to be a Acheroraptor, also no locality besides hell creek form. And measures .35 inch. Last one is probably just indeterminate theropod tooth, maybe can be narrowed to tyrannosaurid? It seems to be a premax and also no locality besides hell creek, measures about .5 inch. Thanks in advance for your opinions. Link to comment Share on other sites More sharing options...

Troodon Posted September 7, 2022 Share Posted September 7, 2022 Since you place the images why cannot you keep similar ones together makes identification easier. 1 is a Tyrannosaurid need base photo 2 is a Tyrannosaurid need base photo and if you do not have a locality it only can be an indeterminate Tyrannosaurid 3 Need locality, serration count and better photos 4 Its an indeterminate Tyrannosaurid Link to comment Share on other sites More sharing options...

Sergiorex Posted September 7, 2022 Author Share Posted September 7, 2022 Sorry, the pictures were in the correct order when I was uploading, im not sure why they were out of order when posted, I’ll try to see if I can get the base for the first one Link to comment Share on other sites More sharing options...
Troodon Posted September 7, 2022 Share Posted September 7, 2022 Not sure if this is whats happened but... When you post multiple photos click the + sign on each in the order you want to see them after download. Don't let the post auto load them 2 Link to comment Share on other sites More sharing options...

JoeS Posted September 7, 2022 Share Posted September 7, 2022 #2 is a Nanotyrannus lancensis tooth. I did request all the information from the seller a few weeks back, it was found in the Hell Creek Fm., Powder River Co., Montana. Both @Troodon and Peter Larson helped in the ID. For future posts, I would suggest you get all the info and images relevant to ID these teeth beforehand, just easier for all of us then 1 Link to comment Share on other sites More sharing options...

Thanks I look at so many teeth with my PM's everything is a blur 1 Link to comment Share on other sites More sharing options...
