eliotvanotteren Posted June 2, 2019 Share Posted June 2, 2019 (edited) This and others like it were found on a dredge spoils beach on the Jekyll river on jekyll island, Georgia. Thank you for your help identifying this partial fossil. I presume it is a tooth, but I have been unable to find a reference for ID. I found four partial pieces similar to this, but the one in the photographs is most complete. There are two holes with a depression between them, and grooves on the outside edges on either side of the depression. Any help would be appreciated. Ruler represents inches.

Brett Breakin' Rocks Posted June 2, 2019 Share Posted June 2, 2019 Hi There, Welcome to the forum ! This is commonly referred to as a Tilly bone. Hyperostotic (swollen/excessive growth of bone) fish bones .... They come in all shapes and sizes. Cheers, Brett Link to comment Share on other sites More sharing options...

Brett Breakin' Rocks Posted June 2, 2019 Share Posted June 2, 2019 Just now, eliotvanotteren said: Thank you! Sure ... honestly I think they are therapeutic too .. I'll grab one when I see it and start rolling it around in the palm of my hand while I walk, it often has a calming effect ?! .. haha .. I swear. I think that's why so many come home with me too.

Brett Breakin' Rocks Posted June 2, 2019 Share Posted June 2, 2019 Yes, they are still working out the why ... though they are also a modern occurrence in fish as well. People will collect just about everything ...

Interesting paper on the Tilly bones in the link above. Short and with few conclusions--basically a shoulder shrug in scientific paper form.
