Bails Posted August 27, 2022 Share Posted August 27, 2022 I recently found this large 2.5 inch Isurus desori tooth and it got me thinking… what is the largest Isurus desori/oxyrinchus tooth out there? Feel free to post some large ones! 2 Link to comment Share on other sites More sharing options...
siteseer Posted August 27, 2022 Share Posted August 27, 2022 Where was that found and how old is it? I've seen a couple of them near and just over 2 inches long. That would be considered unusually large and yours would be declared a true giant of the species - probably among the largest out there. I think @isurus90064 showed some big ones in the Extraordinary Common Teeth thread. I have one just over 2 inches from the Late Oligocene Chandler Bridge Formation and will have to get a photo of it.

Bails Posted August 27, 2022 Author Share Posted August 27, 2022 Hey @siteseer I found it in Charleston, SC washed out of the Harbor. Definitely Oligocene most likely out of the Ashley Formation. Link to comment Share on other sites More sharing options...
MarcoSr Posted August 28, 2022 Share Posted August 28, 2022 I agree with Jess. Your tooth is definitely the largest that I've seen for the species.

My son commented on that thread, and I'm surprised he didn't forward me a link. That tooth at 2.8 inches is huge. It looks like some really big I. desori are found in the Oligocene of SC. The biggest I. desori that I've ever held in my hand were around 2". I would still be very happy with your 2.5" tooth. Marco Sr. "Any day that you can fossil hunt is a great day."

Bails Posted August 28, 2022 Author Share Posted August 28, 2022 @MarcoSr No problem! And I would definitely agree with that statement regarding the SC Oligocene producing large I. desori. These five, all found in Charleston, SC, are all over 2 inches, but not quite 2.5. Definitely happy with these large I. desori, they are some of my favorite teeth to find! That’s why I wanted to see some other examples! 1 Link to comment Share on other sites More sharing options...
