jchomyn Posted May 3, 2018 Share Posted May 3, 2018 Found on beach Isle of Palms, South Carolina. I'm a fossil novice. Possibly a large fossilized shark's tooth...8cm length. Could use some help! Link to comment Share on other sites More sharing options...
BigJim2500 Posted May 3, 2018 Share Posted May 3, 2018 I don’t know a whole bunch about fossil shark teeth, but to me, this looks like a coincidentally shaped tumbled stone. There isn’t really any semblance of bone/enamel structure that I can see, and texture looks very similar to most smooth rocks on the shoreline. The size is so big it would only indicate Megalodon, but even the shape is off it that were to be the case. I think that this may just be a stone that is chipped on the one end. Good luck in the future! 2 Link to comment Share on other sites More sharing options...
Draconiusultamius Posted May 3, 2018 Share Posted May 3, 2018 I second Jim's observation about this being a rock, though I'm no expert either. Link to comment Share on other sites More sharing options...
caldigger Posted May 3, 2018 Share Posted May 3, 2018 It might be a solidified burrow that has been rolling around in the surf zone getting smoothed and polished. But definitely not a tooth of any kind. 1 Link to comment Share on other sites More sharing options...
hemipristis Posted May 3, 2018 Share Posted May 3, 2018 Dugong rib piece. They're solid bone, and frequently show up on Carolina beaches 1 'Those who cannot remember the past are condemned to repeat it.' George Santayana Link to comment Share on other sites More sharing options...
BigJim2500 Posted May 3, 2018 Share Posted May 3, 2018 Hemipristis, I see where you could be going with that guess, but this seems to be (a) so polished down that you can’t say either way with much confidence, and (b) seemingly too small to fit into easily being dugong if it is the beginning of a rob like it seems as though you are positing. Although I agree they can be solid, I don’t think that should means that this is a guaranteed fossil. Link to comment Share on other sites More sharing options...
BigJim2500 Posted May 3, 2018 Share Posted May 3, 2018 Sorry, RIB, not rob. Link to comment Share on other sites More sharing options...
sixgill pete Posted May 3, 2018 Share Posted May 3, 2018 @caldigger is spot on with his ID. It is a fossilized infilled burrow cast. Very common in some of the exposures here in eastern NC. basically it is fossilized mud. Not a dugong rib.
