Dustink- Posted October 31, 2022 Share Posted October 31, 2022 I’m an avid arrowhead hunter and collector - came across this tooth in north east Oklahoma - any idea -I don’t think it’s shark as it’s to round and serrated . 3 Link to post Share on other sites
Styles Posted October 31, 2022 Share Posted October 31, 2022 (edited) Was following this thread on Facebook. Thanks for posting it here - very curious to see where this ends up. Based on the photos I presume it came from a river, so it could really have originated anywhere. Was this the arkansas river? Edited October 31, 2022 by Styles Link to post Share on other sites

Troodon Posted November 1, 2022 Share Posted November 1, 2022 Well my expertise is with Dinosaurs and I can assure you its not that. So cannot help other than trying to figure out age Triassic exposures are in the very northeastern corner so if it was found in the Arkansas River it good chance we can eliminate those deposits. Given the preservation and size my guess its Permian in age. @dinodigger 2 1 Link to post Share on other sites
Carl Posted November 1, 2022 Share Posted November 1, 2022 (edited) I suggested posting it here because, well, it's a sea of experts. I agree that it isn't a dinosaur, nor a shark, as suggested. All I can suggest is maybe some early archosaur or even a synapsid. But the Permo-Triassic is loaded with many other excellent oddities that could claim this tooth. Very, very intriguing! I'll also alert colleagues who know EVERYTHING about the Permian and Triassic. Stand by. Edited November 1, 2022 by Carl 2 2 1 Link to post Share on other sites
Dustink- Posted November 1, 2022 Author Share Posted November 1, 2022 I think you're right - I’m leaning towards Dimetrodon tooth it looks very similar in size and shape. 1 Link to post Share on other sites
Troodon Posted November 1, 2022 Share Posted November 1, 2022 17 minutes ago, Dustink- said: I think your rite - I’m leaning towards demetrodon tooth it looks very similar in size and shape Not sure Dimetrodon teeth have those type of denticles. The larger denticles include minor ones a more leaf type.. If serrated, depending on species, the denticles would look like this. 1 1 Link to post Share on other sites

Troodon Posted November 1, 2022 Share Posted November 1, 2022 No, the denticles in B are individual and all about the same size and shape. The denticles in your specimen vary in size/shape with the larger ones having smaller denticles. Very different. 1 2 Link to post Share on other sites

Dustink- Posted November 1, 2022 Author Share Posted November 1, 2022 So any advice on how to identify what it belongs to , as I’m sure it was larger - missing the tip and base . Or what my next step should be Link to post Share on other sites
JohnJ Posted November 1, 2022 Share Posted November 1, 2022 A bit of patience to give some other members time to see the tooth. 2 Link to post Share on other sites
FossilDAWG Posted November 1, 2022 Share Posted November 1, 2022 I was just typing the same advice. People have jobs/lives and most are not on the Forum 24/7. 1 Link to post Share on other sites
Dustink- Posted November 1, 2022 Author Share Posted November 1, 2022 Oh I completely understand people are busy I was just referring to the part where Carl and I were talking about the photos and differences , or in what direction I should be looking , Is all I meant Link to post Share on other sites

Might have to wait on my colleagues to direct. The one who focuses in the Permian said "Definitely not dinosaur and very hesitant to say Permian. My guess is way primitive lizard-oid Triassic." Still awaiting a response from my Triassic guy. 1 Link to post Share on other sites

Dustink- Posted November 1, 2022 Author Share Posted November 1, 2022 Thank you btw , everyone for chiming in and trying to figure out what this tooth may be it’s much appreciated Link to post Share on other sites
ThePhysicist Posted November 1, 2022 Share Posted November 1, 2022 If we're talking NE OK, then it's likely Permian/Carboniferous in age, as aforementioned (while transport from a different region is possible, it seems reasonable to first consider the fauna common in the Permian/Carboniferous). I don't see why it can't be "shark," in fact that's what first came to mind. My vote is an Orthacanthid cusp - I see a similar cross section and serrations on some of mine (can provide pictures later). 3 Link to post Share on other sites

I've never seen anything like this, but my mind immediately went to shark tooth. The complex serrations are similar to serrations on some younger sharks. 1 1 Link to post Share on other sites
