Found on the coast of Hilton Head South Carolina USA. I am quite unsure of what this is, it’s very eroded and might ether be unidentifiable, or just a funny looking rock. However, I find it looks very tooth like, with one wide end, and one pointy end, as well as a cavity that is open at the wide end and gently tracks further into the “tooth” My first thought was a premolar of some sort of primitive whale sans the roots. But that seems unlikely. Please share your thoughts! I’d love any sort input and if you would like a better picture of a certain angle, let me know! Here are the pictures 1. Front side 2.Back side 3.Right side 4.left side 5.Top side 6.Bottom side And here is a video of the specimen rotating! (ignore the sparkling putty, it was the only option I had to get it to sand up nice while still being visible at all angles) IMG_0199.mov

Between 2020-23, two collectors who scuba dive for fossils throughout Florida and Georgia have recovered 5 chesapecten (including two paired valves) with morphological characteristics that signal a Miocene age. These characteristics include an acute byssal notch and a byssal fasciole that is strongly differentiated from the shell’s auricle in terms of sculpture and elevation. The largest of the adult shells also displays an active ctenolium. Additionally, one of the paired specimens displays significant gapes between valves when matched (the other pair was preserved as found by glue according to the collector and cannot be matched). These aforementioned traits are also emblatic of Miocene age for Chesapecten. These shells were recovered from the following areas in Georgia and Florida: Savannah River, Effingham County, Georgia (Collector 1) Specimen 1 (W = 108.0 mm) R valve L valve R valve - close up of byssal notch and fasciole (most of fasciole has been degraded) R valve - close up of ornamentation L valve - close up of ornamentation Profile Close up of matrix, gray sand Savannah River, Effingham County, Georgia (Collector 1) Specimen 2 (W = 101.6 mm) R valve R valve - interior R valve - close up of byssal notch and fasciole L valve - note barnacles are modern species, not fossilized L valve - interior L valve - close up of ornamentation on auricle Side profile of pair, showing gapes Front profile of pair, showing gapes Cumberland Island, Camden County Georgia (Collector 2) Specimen 3 (W = 114.3 mm) R valve, note encrustation is recent not fossilized R valve interior, thick shell apparent Close up of byssal notch and fasciole Close up of ctenolium, although modern encrustation makes it difficult to see what is going on in the ctenolium Close up of ornamentation St Mary’s River, Nassau County, Florida (Collector 2) Specimen 4 (W = 117.5 mm) R Valve R valve interior, active ctenolium and thick shell apparent Byssal notch and fasciole Close up of original sediment, note the olive and gray coloration Profile Suwanee River, Hamilton County, Florida (Collector 2) Specimen 5 (W = 69.9 mm) R valve, subadult specimen R valve interior, shell is thick for a subadult Unfortunately, stratigraphic data were not collected for these shells. However, among the Miocene strata from Coastal Georgia and NE Florida currently described in the literature, the Ebenezer Formation of Weems and Edwards (2001), of Upper Miocene (Tortonian age), appears to be the most suitable match based on the age of the Ebenezer and the characteristics of the shells found. The shells collected resemble Chesapecten middlesexensis of the Upper Miocene of Virginia and North Carolina. The Ebenezer was originally defined by Huddleston (1988) as a member of the Coosawhatchie Formation (Middle Miocene). Weems and Edwards later elevated it to formational rank based on differences in lithological and dinoflagellate composition compared to the rest of the Coosawhatchie. The Ebenezer formation consists of gray to olive-gray, fine- to medium-grained micaceous sand and stretches from South Carolina to NE Florida. Five mappable members are apparent and separable by distinct unconformities. The lower four members correspond to dinoflagellate zone DN 8, while the uppermost member corresponds to DN 9. Revision of the Ebenezer to Formational Rank from Weems and Edwards (2001) According to the dinoflagellate zonation of de Verteuil and Norris (1996), DN 8-9 aligns with the Little Cove Point Member (DN 8) and the Windmill Point Member (DN 9) of the St Mary’s Formation of Maryland and Virginia. Alignment of the Ebenezer to St Mary's Formation of MD and VA from Weems, Self-Trail and Edwards (2004) All specimens display similar characteristics which include an acute byssal notch, differentiated byssal fasciole, slightly inflated right valve, and a hinge size in adult specimens that is relatively small for adult chesapecten with the exception of Chesapecten covepointensis (DN 8 St Mary’s Formation) and in some cases Chesapecten santamaria (DN 9 St Mary’s Formation). Also, these shells could possibly be divided into two distinct variants although issues with preservation which appears to be somewhat better outside the Savannah River region may exaggerate these differences. Nevertheless, the Chesapecten collected outside of the Savannah River Region exhibit stronger, more raised ribs and have thicker, heavier shells compared to the specimens collected within the Savannah River region whose shells are thinner and ribs are lower and less pronounced. This is especially true of Specimen 1. Possibly that these variants originate from different members of the Ebenezer Formation. According to Weems and Edwards, “outside of the Savannah region, beds no older than dinoflagellate zone DN 9 occur”. This suggests that the shells collected outside of the Savannah River Region likely belong to Bed 5 of the Ebenezer Formation. Figure 3 of Weems and Edwards (2001) [shown below] suggests that someone scuba diving for fossils in the Savannah River is likely to collect in Bed 4. Therefore, it is possible that the Chesapecten specimens recovered from the Savannah River belong to Bed 4 of the Ebenezer Formation. This stratigraphic information aligns with the observed morphological differences among the specimens and tentatively supports the significance of these variations. Needless to say, more specimens are needed to confirm. Lateral Gradation of the Ebenezer from Georgia to Florida - Fig. 3 from Weems and Edwards (2001) Ward (1992) has remarked that the period between Chesapecten santamaria (DN 9) and Chesapecten middlesexensis (DN 10) represents a considerable loss of the fossil record in the stratigraphic succession of chesapecten. These Chesapecten, which bear a strong overall resemblance to Chesapecten middlesexensis while displaying traits of preceding species (smaller hinge, more differentiated byssal fasicole), could help bridge this apparent gap. Notably, no other Chesapecten in this age range outside of Maryland and Virginia have been reported in the literature. Personal Remarks The equivalency of these shells to the St Mary’s Formation, not the Eastover formation is surprising to me given the strong resemblance to C. middlesexensis. If anyone knows of any findings correlating DN 8-9 to the Eastover, or of the Ebenezer to DN 10 please let me know. Also, if anyone has any additional samples of similar shells from similar sites, even in SC please let me know. Thank you!

Found this years ago by the ocean in South Carolina and have no idea what it is. Thank you for any help.

20240323_135034.mp4 I found this on Folly Beach. It looks like everything is being held together what appears to be concrete like. It has shell face imbetted as well as other marine life. There is one large shell that was held on at the bottom. It is here where I believe the fossilized pearl rest.

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

I’m making a trip down the coastline of North and South Carolina; from Topsail Beach to Charleston. I know there sites in Charleston for basilosaurus fossils, but I’m curious if anyone knew hidden gems of the Carolina coastline

I found these off of charleston SC. i have a fossil book that is pretty extensive however i am completely unable to identify these two fossils, any help with an ID would be appreciated

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:

Hello and thank you for your assistance. Can anyone identify this fossil? I found it in SC , Cooper River. Tooth? Horn? Spike? Again, thank you!

Edisto beach, South Carolina.

Found this in Myrtle Beach. Thought this was a rock at first, but resembled too much like a tooth. Also, I unfortunately don’t have a tape measure or scale with me.
