Hi all, Found this shell in the Antwerp harbor. From the "Scaldisian" of the Pliocene, about 3 myo. I think Kattendijk Formation (can anyone confirm this?). I think it's some kind of shell within the Pycnodonte genus maybe? If so, which one? I am pretty sure that it's from the Ostreidae. Thanks in advance, Max

Hi all, Found this small bivalve in Antwerp, Belgium. Most likely from the Pliocene. That hinge is weird, with that thing sticking out (almost like the Mya shells!). Anyone know what species this is? Thanks in advance! Max

Hi all, Wondering what bivalve species this is. Found at Cap-Gris-Nez, France. From the Jurassic. Looks like it may be a Pholadomya species to me? Not sure... Thanks in advance, Max

Hi all, Just wondering how I should go about with the prep of this one. It's from Cap-Blanc-Nez, France, and the matrix is Cretaceous chalk. Should I prep this using vinegar (and water)? If yes, how? Or is it better to go with the small metal picks? (The matrix is rather soft) Any other tips or things I should know before I tackle this one? Thanks in advance, Max

Hi all, I have been having trouble finding a good guide to use in order to ID fossil seashells (mainly gastropods and bivalves) of the Neogene-Quaternary of Western Europe (mainly Belgium/Netherlands). So, I'm turning to you guys: does anyone of you have a nice up-to-date website/online paper that I could use in order to help me ID all of my different seashells? Preferable with clear photos/drawings of the different species. Thanks in advance! Max

Hello! Here is a larger bi-valve - Is it Glycymeris sp.? As for the sand dollar - Any ideas? These are from the Aurora, North Carolina area. For the sand dollar - I would LOVE a GENUS - but will settle for Family!!!!! I would ALSO love a recommendation for a guide to this area.... I have the Lee Creek Mine articles.... I got a LOT of shark & ray teeth; THOSE i can do! MANY THANKS!

Found in Arkona Ontario a couple weeks ago Devonian age Widder formation 38mm/1.5" across

Hi all, Found this on the Zandmotor, Netherlands. Most likely from the Eem Formation, Eemian, Pleistocene; 120'000 years old. Though most of it is not there, enough of it is present (such as the umbo, and one full side (which allows us to see what the general shape and size would be)) to be identified. I am thinking that it may be Politiapes ruditapes, but that is a wild guess. What do you guys think it is? Thanks in advance! Max

Hello fellow fossilers, I am currently staying in northern Bulgaria, around 30km south of the Danube and there are a some limestone formations close to another local river. I found this fossil and am very curious to identify it! Perhaps it is some sort of bivalve animal but would be great to get some more information. Any thoughts?
-
Hello all, Could anyone confirm or refute the identifications that I assigned to these?

Hi all, I found this modern bivalve at the beach of Wassenaar (Netherlands) some time ago. What species is it? I am anticipating your answers with enthusiasm! Max
-
Hi all, During my trip to the quarry of Resteigne, I namely found this brachiopod. Is this a Sieberella sp (as proposed by Roger @Ludwigia)? Because the fact that it is asymmetrical makes me want to incline to bivalve... But I'm not sure what kind of bivalve it would be then. Location info: Resteigne quarry, Belgium Jemelle Formation (mostly) Eifelian, middle Devonian; ~ 390 mya Thanks in advance for your replies! Max

Hi all, Another very specific bivalve question for you all, this time regarding the freshwater species Corbicula fluminalis. So on the Wikipedia page: LINK, it says that this species is originally from Asia, but was introduced to Europe (and USA). Meaning it was brought here by humans. But, what is weird is that I found 2 fossil specimens of this species (as well as modern ones sometimes) here in the Netherlands! From the late Pleistocene, some 400K years ago. Long before humans had the means to introduce bivalve species like this in new places (and also long before humans came to the Netherlands in the first place). Oh, also, something relevant to take into account is that this species is NOT present in Eemian sediments! (late Pleistocene, 120k years) So how come that this species was "there" 400K years ago, disappeared, and then "came back"? The only thing I would consider as a solution is that the species went locally extinct (while still thriving in Eastern Asia) and was then reintroduced, but what is surprising is that I don't think that one single species could be alive in several different places far away from each other (the distance from Amsterdam to Beijing is nearly 8000 km!)... I don't think a bivalve species could possibly be present in such faraway places. So my question to you all is: what happened? How could it be on/off/on for this species in the Netherlands? Thanks in advance! Max

Location: SE Portage County, Central Wisconsin, USA. Geology: South Western advance of Green Bay Glacial Lobe. Former Glacial Lake Oshkosh. Niagara Escarpment Debris. My land. Ordovician onward. Is this a Straparollous? Holopea pyrene? Left some slightly blurry photos in to show cm size. The part in question is about .4 cm deep by 1.5 cm wide. There is also what might be a bivalve to the right of it, and maybe, chain coral. Dunno about what is shown on reverse. Looking for potential ID on all and anything else someone might see. Wondering if I should give this a toilet bowl cleaner (diluted) bath? The “snail” appears to be a quartz replacement. I did initial cleaning in Biz detergent for about 24 hours, repeatedly and several days in Oxyclean. Brushed after each soak with polyester bristle brush. Did not want to destroy the crystals above specimens, so avoided wire brush. Please let me know what you think. I also want to be sure I am using correct tags here. Since my land contains Ordovician onward period, should I just list Ordovician as the period? Also, how many tags are appropriate? Should they just be location found and potential period, or should they contain generic terms such as snail? If anyone else here is using an IPhone SE for photos and knows some ways to set it, I would be appreciative. I have been unable to figure out how to change the settings for photographing specimens. The camera has a mind of it’s own, and focuses on whatever it wants, even though I am doing everything that my provider told me to do to change the settings for macro. She said phone is capable of it, but required my digging into the depths, which I did. When I transfer photos from phone to computer they come up at 72 DPI. I am using Photoshop elements to change resolution and size, which usually causes photos to be blurry. Upon transfer, I have photos that are about 40 Meg. Once I adjust the size, they are down to less than 2 Meg. Then adjust focus and color cast to be as realistic as possible. I have figured out the best time of day for taking photos with my portable photo tent, LED light and natural light through patio doors. Also made a stable phone holder to help prevent blurry photos. Thinking there has to be an easier way, as each photo I post takes about 5-10 minutes total. Sorry, obsessive compulsive newbie here, lol. Thanks for looking and any comments appreciated. If my ID is off, no problem. top 3 3-16-4 3-16-3 3-16-2 3-16-2 3-16-1 3-16-8 3-16-9 3-16-10 3-16-12 3-26-6 shell side1 Fernwood Acres, on Flickr side 2 snail 1c Thank you.

I found this in a Cretaceous stream in Monmouth County New Jersey. I assume it's a bivalve but I couldn't find anything on in the NJ fossil websites. Anyone know what it is? Thanks! -Frank

Avery nice double valve cockle. Single valves are not uncommon at this site but double valvers are very uncommon for this species.

Hello, I found this bivalve in the dredging materials found along the Orange River near Manatee Park in Ft. Myers, FL. I have consulted the Peterson book, Southern Florida's Fossil Seashells. It is a great book but there is no relevant fossils. Can someone help me identify this fossil? Thank you!

Yesterday I hunted an Upper Santonian Austin Chalk site in Ellis county between downpours of rain. This was my first time at the site. I was looking around a pile of rocks with some boulders mixed in and found this on one of the boulders. It is tiny, whatever it is, about 1 cm wide. Now I must admit that I am more familiar with the fauna of the Upper Coniacian Austin Chalk but to me this looks more like half of the aptychus of an ammonite than a bivalve. Since an aptychus was made of calcite I believe that it would be preserved in chalk, though the actual fossilized material is gone and this is just the steinkern of what ever it was. Here is the best picture that I have of it. Sorry that the quality is poor. I took it while I was at the site and I can’t get a better picture right now. Hopfully this will be sufficient.

This very nice and rare sunset shell was found in an extension of the Rotterdam airport, known as the Maasvlakte 2. One of the favorite bivalves of my collection Another name of this species is Psammobia fervensis, but this name is no longer accepted.

An Anomia ephippium, found in a sandbank in the city of The Hague. This is technically an ex-situ find, because the city itself isn't really a location for finding fossils. The real location would be the Zandmotor or the North Sea; the bivalve here was brought with sands imported from the North Sea. This species is recognizable from the three muscle scars, the pearly shine and the weird little white thing in the hinge area (3rd picture).

Self collected at a sand pit in Columbus County N.C. Most of the time these are found as single valves with the "spines" completely broken off.
