This is in a limestone cave out in West Texas. I don't know anything further, I'm not there in person- the pics are from my brother. It looks a little like a turtle shell to me, but not segmented like they are. What really comes to mind is a crocodile scute, but I don't think there were any giant crocodiles in Texas, and I don't think any of them got quite THIS big anyway. The size of it really has my attention. If it was tiny, I'd think it was some form of invertebrate sea life or another, something I'm just not familiar with. That size, though? I have no idea. (Best picture they could get, it was by flashlight. Second pic shows texture.)

Hope I am getting better at posting what I need ID for. Is this a fossil or a rock that just looks like a claw? Most all my rocks came from Mississippi while in MS Gem & Mineral Club hunting in and around Central MS. Some are from the Big Black river beach area, some are from other areas but sorry I can not tell you exactly, been way too many years.

Hi. Big Brook find need an I'd please. Think the tooth is a sawfish, but I think I found a rib of some sort. Big Brook site, Monmouth NJ, December 23 2019. Should I sent this to NJSM?

So I got this fossil recently. My best guess being a Mosasaur tooth since they didn’t ID the fossil. So I kinda just wanna know since you guys have helped me a lot before, if this is a actual fossil and if it is, what exactly it belongs to. If you need a better image or a different angle to better judge it, go ahead and ask.

Sorry for the meh camera quality, but I found this I guess what I can safety call "rock" in the Dominican Republic a couple of months ago and I just wanna figure out if it actually is a fossil of some type. Someone I knew said it could be a coprolite but I don't know for sure. Just so you guys know, I actually was on this forum before. It's just I forgot the name and had to make a new account because it had been months lol

Hi everyone! I have attached some photos of my first ever fossils! I've been finding fossils of this same species in this one riverbank for years, and have always wanted to know what they are. I did some research- looked through sites detailing some of the more common fossils, and image searches of coral fossils since the texture seemed kinda reminiscent- but nothing seemed to me to look anything like it. I tried to guess with the coral thing, but honestly I can't even place these as animal or plant with any confidence. So now I've come to this awesome site! Thank you all for putting your time into helping people like me out with this, I really appreciate it. I'd love to here any ideas you have! Here's what I do know: When- on the geological map, this area was right on the border between Cretaceous and the indistinguishable riot of eras in the Rocky Mountains that was usually labeled simply Undifferentiated Mesozoic. Where- In a bank of river rocks on the shore of the Clearwater River, in the eastern foothills of the Canadian Rocky Mountains in Alberta, northwest of Sundre. Some Observations- some are circular, some are like a long slug shape, and some are somewhere in between like an elongated circle. The textures/patterns are all similar between them, and I suspect they may be related? The idea occurred to me that the circular ones may simply be slug-shapes seen in cross-section. Whatever they are, there are sure a lot of them- I find a few types of fossil out there, but these are by far the most numerous. I have a single large rock that must have several dozen of various sixes and shapes. Other fossils found there appear in the exact same type of rock, with dark grey background and white fossils. Some of these fossils have vaguely resembled limpets and chitons or other similar-looking creatures, with distinctly grooved shells like a mollusk, possibly supporting the idea that this might be from an aquatic habitat. There is a distinct directionality in the slug-shaped ones- the texture on the 'head' is more even and regularly rounded, while the 'tail' texture is more spiky and elongated. Most have fewer/fainter holey texturing toward the middle of the 'body', but some have holes through the whole thing. The largest is a bit over 3 cm long. Let me know if you need anything else from me! I can provide more pictures, if you feel that would be helpful. I'm very excited to here back from you! Thanks in advance, and have a nice day.

I found this fossil on Filey Beach, North Yorkshire, UK. On the outside, what I assume is a large belemnite is visible. When I cracked it open, instead of finding a long, pointed end, I found a bulbous rounded end. This appears to be where I thought I would find the end of the belemnite. Could anyone ID it for me? Also in the rock was a good sized ammonite but this was separate from the pictured fossil. Thank you for your help.

Hi, I found a bunch of fossils today on our property. Mostly oysters but this one I've never seen. Any help is greatly appreciated.

( the weird succulent plants under it are Lithops, I wanted natural light and they were in the window) Found this along the San Gabriel river near Georgetown, TX. It was in with some small chunks of shale that had broken off the main formation. Pretty sure it's a sand dollar, and I know it's probably not possible to tell exactly what kind, so what I want to know is this: does finding this mean that I should go back and look again? This was the only fossil I found in the area, but it could have been I just didn't know what to look for. And I know there are some fossils that, if you're finding them, tell you "hey, this is a good area for X, Y, and Z because they require the same conditions to show up", but I'm not sure what those fossils are. I find oysters and occasional snails upstream in the loose river rock, if that helps at all. Though, really, there's nowhere in Texas I've seen that doesn't have fossilized oysters and occasional snails. And would anyone happen to have any links to what marine fossils look like embedded in shale, so I can start dialing my eyes in?

Hi any help greatly appreciated. This morning on the coast between Sandsend and Kettleness I found the following nodule with the exposed fossil. I am hoping this is a mammoth tooth but have my doubts - can anyone help me please. Kind regards Steve

Hey, I would like a little bit of help, usually I rarely purchase fossils unless I am myself very familiar with them and can self-ID with confidence (this saves me from rattling over google/books for hours trying to reassure myself). I've always had a liking for Archaeotherium ever since I was a kid (weirdly) and I wanted to get a fossil from this animal, I finally came across what I believe to be a reliable dealer. Someone who prepares the fossils themselves, gets them personally out of the rock on private land and they seem to be really passionate about the White River Badlands. Trouble is my lack of knowledge is winding me up and I'm not too confident, so I would like some second opinions from people who are used to seeing these fossils/can properly ID to back me up a bit. I have already purchased the fossil and if it turns out to somehow not be Archaeotherium, that's totally fine I just want to make sure the ID is correct or not and if not what? Posting a link to the ended listing as I cannot take my own photos of it as yet (hope thats ok), there are clear multiple photos taken from different angles and with measurements. -> *** Thank you in advance!

Could this be fossil wood? Found it in south eastern kansas pennsivanian rock maybe? I know the inverts down the road I got are from penn rock
