Hello! I have collected quite many specimens with Trochactaeon snails from April to May 2020. They all come from the Upper Santonian to Lower Campanian upper Geistthal-formation or Lower Afling-formation of the Gosau of Kainach in western Styria. Some of the specimens contain abundant black, wavy, "folded", shell fragments. They seem to grow on the Trochactaeon snails in some places. They resemble small oysters in some ways. Unfortunately, I have not found anything conclusive about their identity. I found a pic in a paper of Kollmann (2014), with some somewhat similar, unidentified bivalves growing on an Upper Cretaceous snail (last pic). Other accompanying fossils are very rare fragments of phaceloid coral colonies (they to not grow on the snails, though). Any suggestions are highly welcomed! Thank you very much! Franz Bernhard First specimen is a double sided polished slab with abundant black shell fragments. Some of them seem to have grown on the Trochactaeon snails (epibiontic?). Here are some individual polished snails with bivalve fragments. Some of them seem to have grown on the snails (white polygons). The circular things in the middle left pic seem to be the same; there is a snail shell just a few mm below the polished surface at this spot (the specimen is very thin there). Rarely, also on weathered surfaces these bivalves(??) can be seen, growing on the snail shell. But I am not really sure, if this is the same thing as in the polished sections or if this is something else: This is the reference pic from Kollmann (2014), epibiontic bivalves on Nerinella grossouvrei. Thanks a lot!

Myophorella, extinct clam genus, Cretaceous in Argentina
traveltip1 posted a topic in Fossil Hunting Trips
I found these 3 silicified specimens of the extinct clam genus Myophorella, Order Trigoniida, in Cretaceous formations, near Chos Malal, Argentina, South America.

Found this little fossil in chert/flint gravel, and heard a rattling. Upon breaking open, there was a smaller lighter coloured fossil inside, leading me to believe it is some sort of nut. It has what looks to be a scar at the bottom, possibly for attaching? it split neatly along the line into two parts.

I found this a few weeks ago at DSR on the NYPS trip to madison county. Im having some trouble ID’ing it. Doesn't seem to be anything like it in Karl A. Wilson’s Field Guide to the Devonian Fossils of New York

I seem to be having a slow week at work, and didn't have much at home demanding attention, so I decided to spend a day fossil hunting yesterday. I got up with intentions of checking out a new spot on the NSR, but when I looked at weather radar, there were showers in that area. The parts of NSR that I have seen are pretty tough to get into and out of when things are wet, so I changed my mind and made a drive to Post Oak Creek. One trip this spring was the only time I'd been there, and I didn't know what to expect in mid summer, but it is one of the most fossiliferous places I've ever seen, so I was sure a trip there would be fun. And just like my first trip there, I found teeth. I've found very few teeth of any kind in all the other places I've fossil hunted, so I really enjoyed my time crawling on knee pads, looking for teeth. I considered bringing my sifter, but decided I would just stick to searching the sand bars. It was a dark day for the most part, with light rain on and off, so not the best day for trying to spot tiny teeth on the sand bars, but I did find enough to really enjoy myself, and the clouds did help keep the heat from getting too bad. The really small tooth in the upper left corner was the only Ptychodus tooth I found yesterday. Lots of the teeth are broken, damage from tumbling on the rocks, I guess. I always marvel at how sharp many of them are.

Clast bivalve....that is all I know about this specimen I collected. It is preserved very well. I found it in a spoil pile after they dug out a lake. It is my favorite shell fossil. If you could ID it for me, that would be super. Found in North Port, FL. 10 miles East of Venice, FL. The clast is 4inches x 4 inches x 4 inches. Other fossil material in that area ranges from Meg teeth, whale vertebrae, Equus. ID appreciated.

Hi! I recently found some large nacreous bivalves, which are embedded in concretion-like cobbles. The matrix is very easy to remove, but the nacre starts flaking as soon as it is exposed to air. Is there a product to stabilize these without future discoloration? Thanks! (Also if anyone can identify, that would be cool--they come from near Scenic, SD)

Anyone able to help me classify this bivalve. I interpret it as some sort of Infaunal bivalve but could be totally wrong. The specimen was collected at Rhoose point on the Jurassic Heritage Coast Vale of Glamorgan, South Wales from the Blue Lias formation.

Fairly slim pickings today but we picked these up and don’t see so many of them. Any ideas on the bivalve? Is the ammonite Pleuroceras Solare ? Thanks for looking

Hello all, I believe that one of these is a foraminifera, not too sure if that tiny bivalve and snail would be considered one or not. Anyone have any ideal what period these may be from? Was digging some old bivalves and gastropods out of some sandstone and came across a boulder that had hundreds of microfossils mixed in it's debris. The size range from what you see here to less than 0.50mm. Some if this stuff is really cool looking.

I found these and am wondering if they are brachiopods, or just bivalves with symmetrical valves, as I have not yet found a brachiopod in this location yet. Sorry the photos are dark. Many thanks.

New member here. SO glad I found this site! I was about to purchase a very very realisitic segnosaur egg. Some of you who posted, just saved me $65.00! on a fake egg! THANK YOU!

Kiowa formation and Albian. Approximately 1.3cm long and its quite flat and thin. Not sure if it's brachiopod, more specifically a lingula brachiopod, or a bivalve. Unfortunately the umbo is missing so I'm not sure if it's symmetrical or not. I'm leaning more on bivalve but I would like to read your opinion. What's the lowest taxonomy level you can identify?

Hi Everyone, I found this specimen a while back and have been trying to identify it but have been unsuccessful. Its from a layer of shale within the Winterset Limestone, Kansas City group, Upper Pennsylvanian, Carboniferous. Scale in mm. I flaked it off a bigger piece that had bivalves in it which I'll post below. The depth of the flake is about 1/4th of an inch (6.35mm) thick. The fossil doesn’t carry through to either side of the flake. The piece at the top is the same specimen just what came apart when I cracked it. At the moment my guess is that it might be a bivalve of some sort but I can't find any that look similar. Here are some other bivalve species that were in the same section. The color difference is from me scrubbing it with a brush which removed the gray matrix. Any feedback is much appreciated as I can't find anything close.

I found this oyster fossil in a creek bed on a walk with my son in Austin, Texas sometime in May 2020. I believe it was in a Quaternary geologic formation. I’ve collected a number of these, but never with a pearl. Just curious if anyone else has seen one!

i found another bivalve in the creek today here is what my book says about it
matthew textor posted a topic in Fossil Hunting Trips
I found a cool bivalve fossil in the creek today here is what my book says about it its is called Goniophora perangulata Trapezoidal shell, with length typically twice the height.Ventral margin curving with sinuosity in anterior third and slight constriction at the posterior end.Surface with fine concentric growth lines. to 60-90 mm

Hello there! I took advantage of the nice weather we've been having to visit Mimico Creek in Toronto, Ontario (Georgian Bay Formation, Upper Ordovician) yesterday afternoon. Here are some photos of specimens that I'd like help identifying - perhaps @Tidgy's Dad would like to have a look? Firstly - the whole rock which contains the bryozoans and the unknown black objects: Specimen #1: a nice branching bryozoan - perhaps Homotrypa? Specimen #2: a nice encrusting bryozoan (there are actually two of them) - perhaps Mesotrypa? More to come...
