Can anyone help identifying these specimens? They were found in marine Cretaceous sediment in eastern Alabama. If they are bivalve, I could not locate the bottom halves.

Unionoid mussels are very common in this riverine deposit. They preserve the original nacre and are iridescent. Because they are so fragile, and given they were preserved in a river, they are never complete.-

The following were found in Sarasota County, Florida (USA) on public land eroding out of berms. They appear to be plio/pleistocene. Using the forum and several books, I've ID'd the best that I can. I'm looking to confirm the ID's. Any and all assistance is appreciated. 1. Turritella acropora 2. Arca wagneriana 3. Eucrassatella speciosa 4. Terebra dislocata 5. Carditamera floridana or arata 6.

Hello everyone, I was just walking the beach on the Adriatic coast in Croatia and I found this rock with a seashell imprint inside, I am wondering could this possibly be a fossil or just a regular part of a seashell, it still has parts of shell in it. The rock I thinks is limestone which is the most common here. I appreciate your answers.

Found this in a cliff side in Colorado I am not sure but it looks like a mollusk or Crinoid bulb, DINOSAUR EGG!😆 Thanks!

Well, I’m stumped. Can’t find anything like it in my references. Was found in KC area, likely Pennsylvanian. Thank you so much in advance everyone!

I don’t find these too often, and rarely can they be extracted in a way that looks good (in my limited experience), but these two were found as shown already separated on all sides. The bigger one is REALLY big compared to those I usually find. I placed a smaller one found in the same spot right next to it for comparison. I tried to use Lance Halls northtexasfossils site to find something similar and there’s a Pennsylvanian specimen that sort of looks similar, but many of his pics aren’t loading properly so I don’t know if I overlooked a likely candidate. Any ideas? This is Tarrant county TX, a spot where I can find exposure of kiamichi clay and Fort Worth formation as well as duck creek.

Well I yesterday I drove to one of the Keasey outcrops here in Oregon (the one with the Cold Seep). You cannot dig here in Oregon without a permit or landowners permission, so I hunt the talus along the road. Yesterday I picked up about 25 specimens. Interestingly, many were weathered out and among my largest finds. The mollusk (some shell present but mostly a cast from the shell as mold) measures 66mm on the long dimension and the gastropod 34mm across. The mollusk on the right is the average size I find in the Keasey formation. Both the Mollusk and gastropod are significantly larger than my normal talus finds. I don't know if this is because of the Cold Seep or just the particular set of finds. I do find lots of shells showing predation like the small one on the right. Any it was a fun day looking through the talus and well worth the trip.

Hello everyone, just trying to get species names if anyone knows. I know that 1 and 3 are from Yorkshire, England. I don’t know the location of any of the other species unfortunately. Thank you.

Looking for help identifying any of these fossilized shells and internal casts. All found in southeast Florida, Broward/ Miami-Dade counties [Pleistocene Miami Limestone/Oolite]. Maybe a few found more westward in the Tamiami Formation [Pliocene/ Miocene Limestone] Thanks. Fossil Shells.pdf

I found these Devonian bivalves (?) at the Milwaukee formation at estabrooke park in Milwaukee Wisconsin. I think the first one could be a bivalved arthropod like an ostracod and the second could be part of a brachiopod. Any help is appreciated! Thanks. Sorry for lack of scale! I just put one in my rockhounding bag.

It’s been a while, but now I’ve got something worth posting about that I’d like identified. :) Took a trip to Lake Texoma yesterday and my husband found this. My guess is some kind of bivalve, but I’m hoping that someone here has a little more knowledge.
