Hey y'all! I did a little hunting on Morris Island, SC this afternoon and came across this interesting fossil. At least thats what I assume it is until someone with more knowledge tells me otherwise It is 3" long and 2.5" in diameter. Thanks for having a look!

Thanks for any help with these — the last 4 unidentified teeth from my recent trip. C — looks in profile like a generic Carcharinus, but the root is very robust! Perhaps symphyseal or pathological? From Summerville, SC. D — The cusplet-like serrations are suggestive of Hardnose shark (C. macloti), but those are rare in the Atlantic according to (https://www.fossilguy.com/gallery/vert/fish-shark/carcharhinus/index.htm). Also the root seems unusually broad. The edge of the enamel is broken off one side of the crown, as visible in the third image. From Morris Island, SC. E — At a loss on this one! The enamel:root ratio is very low! Pathological? From Summerville, SC. F — Seems bull shark like (C. leucas), but the tooth and root are very thick. Symphyseal or pathological perhaps? From Summerville, SC.

Thanks for any thoughts on the species here.

Good morning fossil friends! Found this unknown fossil on Morris Island, SC yesterday. Morris Island is an uninhabited island near Charleston and was used by the port authority to dump dredge spoils from the Charleston Harbor for many years. During big tides or storms, the impoundment walls erode and deposit fossils, shells, etc. on the beach. I'd love your help in ID'ing this fossil. Thank you!!

After I remarked that the little tooth below (found on Morris Island, South Carolina) looked interesting on his trip report thread, forum member @Family Fun kindly gifted it to me, asking only that I help identify the species and share the result. My assessment is that this is an Isurus retroflexus posterior tooth, but hopefully others here can either confirm or correct that ID. This tooth has a non-serrated crown that is still fairly sharp and to my eyes at least has the raised labial platform indicative of I. retroflexus. There is a single cusplet on one side. Thanks for your help with this one, and thank you @Family Fun for your generosity! (Unfortunately, the tooth split down the middle on its journey to me, which is the crack you can see in the photos, but I was able to glue it back together.)

On Friday I went on a guided trip fossil hunting on Morris Island through Charleston Outdoor Adventures, a chartered trip and rental company operating on Bowens Island. I must say I was thoroughly impressed with the operation as a whole. Their guides were friendly and knowledgeable, and I would highly recommend their service to anyone looking for a guided adventure in the Charleston Area. Anyways, we departed Bowens Island on a large Carolina Skiff for a 20 minute zip through the salt marsh before landing on the northern end of Morris Island. I remember that everyone slowed down looking for shark's teeth, but the guides kept up the pace because they knew we wouldn't find anything yet! But as we approached the jetty rounding the curve of the island, I began to see the familiar triangular shapes of teeth. One guide led the pack, while the other brought up the rear. The smaller kids would stick close to them because they'd circle any tooth they saw with the broom handles each of them carried. I typically stuck near the back of the group just because I moved slower than most of the rest of the group because I was looking for fossils, which I certainly found in abundance. Sometimes it surprised me how large of teeth had been walked past by 15-odd people already. Interestingly, unlike some of the fossiling sites along Charleston's coasts, the teeth here were not deposited as a result of beach renourishment with dredge material, but rather they were eroding out of some small cliffs further down the beach. As we got closer and closer to it, we'd find larger and larger teeth. One of the guides told me a story about how one of his friends had found 4 associated shark vertebrae in the cliff face. I found myself a nice angustidens or two, a partial porpoise tooth, and some larger but beat up teeth. Both of my little brothers had a great time and found some great teeth, and overall this was a great experience.
