James Savage Posted October 22, 2023 Share Posted October 22, 2023 Hello everyone Couple of unusual finds for me from diving in the Cooper River, near Charleston, SC. This river cuts through Oligocene to modern deposits so it can be tough to ID finds. The first looks like a Castoroides sp? broken beaver tooth? The shark tooth has a U shaped root, no serrations on the blade, and has cusps that appear to have a gap between the root and blade. Looks like a cusped P. Benedeni or possibly an upper lateral sand tiger (based on looking through elasmo.com). Doesn't look like an O. Angustidens or A. Grandis to me? I've seen a few cusped Benedeni's identified on the forum and was curious if that is what I found Thanks for looking 3 Link to comment Share on other sites More sharing options...
old bones Posted October 22, 2023 Share Posted October 22, 2023 I can't help with the shark tooth, but you might explore the possibility of Neochoerus pinckneyii, the capybara. Link to comment Share on other sites More sharing options...
old bones Posted October 22, 2023 Share Posted October 22, 2023 A search on The Fossil Forum does show some finds like yours to be Giant Beaver! Link to comment Share on other sites More sharing options...
Fin Lover Posted October 22, 2023 Share Posted October 22, 2023 My guess on the tooth is benedeni but I haven't found any yet myself, so I could definitely be wrong. Fin Lover My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

hemipristis Posted October 24, 2023 Share Posted October 24, 2023 If I understand correctly from reading TFF posts, it’s not unheard of for juvenile benedinis to possess rounded cusps 'Those who cannot remember the past are condemned to repeat it.'
