I have been working on sorting teeth I've collected from the Chandler Bridge Formation (Oligocene, ~28 MYA) from one site by species. I've not put adequate time into learning how to differentiate the smaller teeth such as these, and am working on filling those gaps in my knowledge. Here I have isolated 6 "distinct" types of teeth that I am attempting to put a name on. Apologies on the photo quality, I was in a bit of a rush, hopefully there is enough detail to understand the general characteristics I am attempting to distinguish between. 1. Wide root, flat and, typically, curved to one side. Is serrated from where the enamel meets the root all the way down onto the blade. 2. Wide thin root, thin straight blade, serrations. 3. Almost identical in shape to number 2, except straight blade with no serrations. 4. Larger teeth in general compared to the others, curved and straight blade with nos errations, has enamel "wrinkles" similar to serrations near the root only. 5. Very stubby root (horizontally compressed and somewhat more bulbous than the other teeth). Long, straight blade with no serrations. 6. Smaller in general than the other teeth. Serrations along root, but not on the blade. Blade is slightly curved. These are my proposed identification of the teeth: 1. Reef/Requiem shark upper teeth of some kind 2. Unknown 3. Lemon shark lower lateral teeth 4. Lemon Shark upper teeth 5. Lemon shark lower central teeth 6. Requiem shark lower teeth

My first contribution to science
Fin Lover posted a topic in Partners in Paleontology - Member Contributions to Science
I am excited to finally announce my first contribution to science! This is a section of dentary/beak of a Pelagornis cf. sandersi from the Ashley Formation in Summerville, South Carolina. This was found in December 2023 and has been donated to the new Charleston Center for Paleontology, where it will reside in their collections. A paper featuring it and other Pelagornis sandersi fossils from the area (which there aren't many of) is in progress. Here it is after prep:- 11 replies

Hello — I would love your help IDing these shark teeth: #1 — I think it symphyseal, perhaps P contortus. 10mm in length. From the Peace River of FL. #2 — Rather unsure about this one. Seems somewhat like a lemon shark tooth, but if I had to guess I would go with I retroflexus. 12mm long. From the Peace River of FL. #3 — New to me. Just under 3mm in length. From a creek in Summerville, SC. If I had to guess I would say a member of the Triakidae (hound sharks). As I understand it, this would be fairly unusual for SC, but this clade is attested for this locality in the literature https://bioone.org/journals/acta-palaeontologica-polonica/volume-53/issue-3/app.2008.0306/New-Fossil-Triakid-Sharks-from-the-Early-Eocene-of-Prémontré/10.4202/app.2008.0306.full. No idea about species or genus! Cheers!

This was my first angi, and maybe my second shark tooth ever. Still holds a very special place in my heart.-
