Found this large bivalve/clam in the new creek bed spot I discovered. As mentioned in a previous post, the spot is mainly Great Valley complex sedimentary rocks (Cretaceous), but also bordering Eocene sedimentary, Miocene sedimentary, and some intrusion of Pleistocene alluvium known. This was free-floating. These type of white clam fossils are relatively common in the SF Bay Area, but this is by far the largest I've found. Can anybody speculate as to how rare this size/quality of specimen is? It measures 48mm x 45mm x 37mm and quite dense/heavy. Any taxonomical speculation would be appreciated as well. Thanks in advance! RCD

I found this clam buried in mud along Joshua’s Creek in Oakville, near Lake Ontario, the hotspot of Ordovician fossils. Measurements are 7cm by 6cm. I’m particularly intrigued by the growth rings, since they protrude out rather visibly and considering I’ve never seen this in any other kind of fossil or living clam species. Can anyone help with identifying what species of fossil clam this is?

Anyone know the species or genus of these?

Looking for some help on this shell specimen. It was part of a large rock and mineral collection I acquired not long ago but unlike the rocks and minerals this was not labeled, so I have no location info to offer. Thx in advance.

Had a couple hours to hunt one of my local spots this evening… I didn’t find much, but I did manage to pull a nice little bivalve shell embedded over an ammonite imprint. cheers!

Spiny bivalve from Upper Triassic limestone at Aust Cliff, Gloucestershire, UK
Georyx posted a topic in Fossil ID
Hi everyone, First time posting here so please forgive any dodgy formatting. I found this bivalve shell in the Upper Triassic limestone beds at Aust Cliff, Gloucestershire, UK. I posted this on Reddit and only one person managed to have a guess at a Ctenostreon bivalve genus, but they are not sure. The spines on the edge of the shell seem a bit too evenly-spaced out in my opinion. (By the way, the grooves surrounding the shell are from where I've engraved the fossil a little. I don't have the equipment to fully extract it, so I have no idea what the outside of the shell looks like). Thanks all - any help would be appreciated. - Georyx

I collected this bivalve cast a couple years ago in the Silica Shale (Middle Devonian) of Michigan. I'm not super positive on an ID and was hoping someone here might have some thoughts. @Peat Burns @Misha @Tidgy's Dad? Thanks for any help.

Hi everyone, I am not a specialist in paleontology, I would like some help in identifying these 3 stones. I found them in clay from a marine environment dating from the Cenomanian... It seems to me that there is a bivalve, a vermiform fossil (?) and one resembling a degraded bone. I do not know well the paleontological discoveries of my region, I just know that there was the discovery of a vertebra of a marine reptile and the tooth of a sauropod. Thanks a lot for your help

ID requested: Eocene Bivalves & Gastropods (Tielt formation, Egem, Belgium)
ziggycardon posted a topic in Fossil ID
A few months back I recieved a bucket full of material from the (now closed) Tielt Formation, Egem, Belgium (Eocene, Ypresian, 53 mya) The material should be rich in shark teeth (I am waiting for the spring weather to go through it all) but there were some very nice Gastropods and Bivalves in the mix as well. Unfortunately Bivalves and Gastropods are far from my speciality, especially Cenozoïc ones... So I was hoping someone here might have some more experience with these critters here to might ID them. 1: Some Bivalves 2) A block with some bivalves, a gastropod and a Rotularia below. 3: A nice Gastropod 4: A gastropod 5: Another Gastropod
