I am doing some research on some of my newer interesting finds and am struggling a bit on this ray mouth plate: I have a local book that lists it as a Pleistocene cownose ray (Rhinoptera sp.), but in doing literature searches, I cannot find any pictures that have the same design for the "adjoining teeth" (I know that specimens this complete are hard to find). I understand that there are multiple species of Rhinoptera and that it is difficult to tell them apart. I am also finding conflicting information on when the Rhinoptera genus came about (so far, I have found Oligocene, Miocene and Pleistocene). I found this in a creek that is heavily Oligocene but where I have found a layer of Miocene fossils, which I believe (if I understand what I have read) is actually a Pleistocene lag deposit. Can anyone clarify if this can actually be IDed down to the genus (and if Rhinoptera is correct)? Thank you...I have spent the last two days just trying to gather enough information for two fossils for the Collection Reference Museum.

Many creeks in Summerville, SC have multiple formations present, so finding a fossil ex-situ often makes identifying the specific formation difficult, especially for those fossils that spanned multiple epochs. Since Acanthocybium solandri were present in the area beginning in the Oligocene, the following formations are possible: Oligocene: Chandler Bridge Formation and Ashley Formation Pliocene: Goose Creek Limestone (early-mid Pliocene), which contains un-reworked Miocene-Pliocene fossils Pleistocene: Ten Mile Hill Formation, which is a mid-Pleistocene lag deposit that can be found overlying older formations in the area. While many Pleistocene fossils in the area are from land mammals, Miocene-Pliocene fossils have been found in the base of the Ten Mile Hill Formation. ID references: 1. Collette, B.B., & Russo, J.L.

I thought I posted this earlier, but I don't see it, so I assume it didn't save. My apologies if it's a duplicate! I'm having trouble IDing this tooth, found in Summerville in a creek that has mainly Oligocene but definitely has some Miocene from an overlying lag deposit: Slant height is 23mm, width is 17mm. Here are my thoughts: 1. Sand tiger: curve is consistent with sand tiger, but it doesn't have cusps, a nutrient groove, the "bulge" typically in the center of the root, or the typical root shape. Other sand tigers I've found here, all having the root bulge: 2. C. hastalis: both the root and crown seem a little narrow for a hastalis, and the tooth has perhaps too much curve. New tooth on left, with two other hastalis (I believe): 3. I. oxyrinchus: the crown does feel more "blade-like", but the root shape just doesn't match, and the crown seems a little narrow. New tooth on right next to what I believe is an oxyrinchus: So, what am I overlooking? Also, feel free to correct any incorrect IDs on my comparison teeth. Thanks for the help!

Found this tooth in the Summerville area yesterday in a creek that has both Oligocene and Miocene fossils (Miocene comes from a Pleistocene lag deposit). My guess is a thresher of some sort, as I found 3 other threshers there yesterday, but this one looks different than the others (and the 4 or 5 other ones I've found in the last year). I just don't know what else it could be, if not thresher. The root here made me think Paratodus, but it otherwise doesn't look like a benedini: Two more typical threshers found in same creek yesterday (ones I find usually have little cusps also): New tooth on right, tooth previously IDed on forum as thresher on the left: 14 mm slant height. Root is 4 mm thick at thickest part, while the blade is only 1-3 mm. Thanks for any input!

I have seen a lot of isurus retroflexus, but this one looks more barrel shaped where the enamel meets the root.

I found these in a creek in Summerville SC. I’m still new at this and not sure what they are exactly. Any help I’d appreciated.

Is this a symphyseal tiger shark tooth or something else? I'm struggling to get good pictures, since it's only an 8 mm slant height, so hopefully these will do. Compared to a posterior tiger: Thank you!

I found what I thought was a tiny piece of jaw (11 mm long and 5 mm thick). My rookie guess was rodent, fish, or something else small. The hole/socket size is consistent with a piece of rabbit jaw I have, but the holes seem to be a different shape (I think...my rabbit jaw still has teeth in it). However, the rabbit jaw is smooth bone on both sides and this one is smooth on one side but has a pattern similar to a pharyngeal grinding plate/mill on the other side (which I didn't notice immediately). So, is it a grinding plate that happens to have holes on the end, or a jaw that happens to have this pattern? Thank you!

I haven't posted a trip report in a while and, although I didn't find anything amazing yesterday, I thought I would show what a decent day looks like for me. I would have loved to have hunted for a few more hours, but health problems limit what I can do. I don't find many I. retroflexus, so this was nice. It has a really pretty sheen. I like posterior angustidens, but I always find them missing a bit. All of the day's angustidens were broken. I don't find a ton of odontocete teeth, so I enjoy finding them (I think that's what the 3rd one is): And then just the usual miscellaneous (verts, ray parts, steinkerns, etc.): And, of course, other shark and barracuda teeth. Some are in good shape (1st pic), but there are always a ton that aren't (2nd pic): Other than that, there are some random unidentifiable bones and bits that aren't worth showing (including a possible root of an odontocete tooth with no crown at all). So, there is a decent day for me. No cow sharks, no mammoth or sloth teeth, but I got to enjoy nature and pick up a few fossils. Thanks for reading!

I found this tooth (half) in a pleistocene lag deposit outside of Summerville, SC. A local guide, author, etc. said it was a fish tooth, but he couldn't remember off the top of his head what kind. Is anyone able to ID it, or is "fish tooth" the closest I can get? Thank you!

Found ex-situ, so I have included both Oligocene formation possibilities (Chandler Bridge Formation and Ashley Formation). References: Cicimurri, D. J., & Knight, J. L. (2009).
