Hello TFF friends! During the summer, in August I was able to take a trip to northwestern PA to collect some fossils at various locations. One of them had many different types of trace fossils which I did not collect (something I regret doing as those ichnofossils were quite interesting and beautiful), but I also found this piece, it is a thin sandstone piece containing multiple bivalve steinkern a from 1 to about 2.5cm in length. I am not sure what formation it was, the closest I can think of that is present in the area is Lock Haven but that one mostly has brachiopods and I didn't get a single one of those. I know these are bivalves because the shells have very similar form, some are paired just like two opened valves of a bivalve and two display growth lines along the shell, unfortunately those are very hard to see on camera. I was wondering if anyone knows what these might be as I have tried researching the topic myself but have gotten very few results. Thank you very much, Misha

While I was on vacation in the Outer Banks in North Carolina, I picked this up while collecting seashells. I was hoping maybe someone on here would be able to tell me what it is. The rock itself is about 4cm long, while the shell that was impressed in it is about 2cm wide, and 2.5cm long. I'm not 100% on it being a bivalve, but in person it looks too asymmetrical to be a brachiopod.

I've made two posts recently with requests to help id white rocks that were suggested as possibly bivalve. I've been finding rocks like these in the same places as the white ones. They caught my eye because they looked like they had been painted. Up close, the one in posting has a lot going on, but different than the others. It may just be a rock. Help is greatly appreciated

This morning I split this shale (technically it fell apart on me), and found this interesting little fossil. I was thinking that there was a possibility of it being a phyllocarid valve, but I have never seen one. This also raises a question that I have been wondering - how do you differentiate between a phyllocarid and a bivalve valve when the tail is absent? What raised my suspicions on this specimen are the raised bumps on the external mold and the depressions on the cast. The pictures below are of the specimen. The first shows the cast/internal mold, and the second the external mold. It is from the Leighton Formation, Maine; which is Pridoli, Silurian. Thanks in advance for your help everyone! @Fossildude19 @mikeymig

Hi, new to the forum, found this in my aggregate in my drive, Norfolk uk. Seems too well detailed to be real. Any help appreciated.

Hi ! My girlfriend noticed some fossils from a cimetery wall just next to my appartment (which is located in a suburb really near Paris). Thanks to some geology museum in Paris, we identified this limestone to be from Lutetian. It also happens that the fossils can be directly picked off the rock by hand without damaging the wall. So we got a few of them. Here is what we found : I believe most of them are Sigmesalia, except for the bivalves which I suspect Crassatella. There are two specimen though that draw my attention : I don't think they are from the same species from the others. Maybe some Cryptochorda stromboides I mainly used the forum to find matching species with those, I'm not quite sure whether my identification (nor the method I used) is correct or not. I hope you find this interesting (and beautiful ofc) !
