Kolya Posted August 3, 2021 Share Posted August 3, 2021 Hello! Help please with identification. May be it is symphysis tooth of Galeocerdo aduncus? Height - 9 mm. Western Ukraine. Middle Miocene. Thanks in advance! Link to comment Share on other sites More sharing options...

These members might be able to help you out more: @MarcoSr @Al Dente @cowsharks Hope this helps! Edited August 3, 2021 by Mainefossils 1 1 The more I learn, the more I find that I know nothing.

Your tooth could be a symphyseal/parasymphyseal shark tooth, but the root of your tooth doesn't look like any tiger shark symphyseal/parasymphseal teeth that I've seen before. The below pictures are from an extant Galeocerdo cuvier jaw set. Upper symphysis area of the jaw: Lower symphysis area of the jaw: Marco Sr. 3 "Any day that you can fossil hunt is a great day."

Kolya Posted August 4, 2021 Author Share Posted August 4, 2021 Thanks a lot! Is it possible that it is rear tooth of Megalodon? Link to comment Share on other sites More sharing options...

I have a few small rear Megalodon teeth. Your tooth is pathological and that makes identification more difficult. The serrations do not cover the tip, which I think would argue for Tiger symphyseal. I had to search around a little. Here is the G. cuvier sysphyseal that reminds me of your 4th photo.
