Kbsib Posted March 23, 2022 Share Posted March 23, 2022 Both of these were found on the beach in South Carolina. They may have nothing in common but have similar characteristics to my eye. The first is approximately 2cm while the second is closer to 3cm. Both are symmetrical though the second is not complete. I look forward to hearing just how far off I am!

Fossildude19 Posted March 23, 2022 Share Posted March 23, 2022 These look like hyperostotic "tilly" bones, to me. 1 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

digit Posted March 23, 2022 Share Posted March 23, 2022 Yup. That's what I was thinking. Search this forum for "Tilly bone" or the inter-webber-net in general and you'll see a lot of similar ones and learn how (but possibly not why) they form. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
Kbsib Posted March 24, 2022 Author Share Posted March 24, 2022 Thanks @Fossildude19 and @digit Never heard of a “tilly bone” So it is a fish fossil that can’t really be more specifically identified because of abnormal bone growth. Right? 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 24, 2022 Share Posted March 24, 2022 Correct. Often times they are vertebra, but they can be other things as well. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
