Associated Cenozoic sea turtle carapace from Summerville, SC lag deposit
fossil_lover_2277 posted a topic in Fossil ID
So I just finished piecing together the remains of a partial sea turtle carapace that I dug out of a lag deposit just outside the town of Summerville in South Carolina. Anyone potentially know any taxonomic information on it, such as what genus or species it might be from? Conversion from inches to cm: 10 inches = 25cm; 5 inches = 12.5cm; 1 inch = 2.5cm- 7 replies

I purchased these as Ingenia yanshini which I think became Ajancingenia, which then became and is currently Heyuannia. The formation provided is the Djadochta Formation, but that doesn't seem right since Ingenia/Heyuannia is not found there as far as I've checked. Unfortunately, there isn't provenance other than Mongolia attached to them to say whether they come from the Barun Goyot Formation where Heyuannia yanshini is found. While I'm not necessarily doubting the original ID, I just don't really know. I'm not expecting a positive or diagnostic ID to the genus level, but I wanted to at least know whether or not I can label this to Oviraptoridae indet., possibly Heyuanniinae indet. The original ID is a bit of an odd one, but it might have just been one of the few oviraptorids described at the time. Last I checked, there are now tons of recently described oviraptorid genera in Mongolia and China. The pair of phalanges with supposedly the semilunate carpal attached which I think is the smaller section? I know one of them did have glue in-between them when I lightly smeared it with acetone using a cotton swab. They are associated coming from the same sandstone block, apparently along with other shattered phalanges. Although I don't know if these actually came from the same animal since one looks ever so slightly larger. There is some sort of clump of sand or crystalized piece attached, as well as light beige or cream colored matrix. Not sure if that narrows down a formation, probably not, but I do see a lot of matrix from Mongolia tend to be red-ish color similar to the Kem Kem Beds. Any input is appreciated. There's probably a lesson to be learned here . . .

Hi all, sorry for the long post, in advance! I purchased these unprepped with some other stuff, but these bones have lines running thru these that almost looks like quartz? Is it glue that you can put on in the field? The pics don’t do it justice at all, it’s a translucent blueish green, second question I’ve got is, are they associated? They don’t seem to fit together, but they are all the same Color of bone and all the same color of line going thru it? Last question, if they’re are associated what did they come from, and what bones are they? @Troodon @jpc @hadrosauridae. TIA
