  1. 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
  2. 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.
  3. Complete grammysia bivalve

    From the album Middle Devonian in Central New York

    Grammysia bisulcata Upper Ludlowville Formation Hamilton Group Middle Devonian Brookfield, New York Collected 7/18/20
  4. Shell Cast Fossil

    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.
  5. Jurassic Bivalve ID

    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.
  6. 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)
  7. Whitby finds

    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
  8. Devonian Bivalve? from Paulding

    I found this small "clam" last week at the Paulding Community Fossil Garden in Ohio. This specimen was found loose but likely came from the Silica Shale (Middle Devonian). It has a bivalve-y look, similar to the bivalve Mytilarca cordata which is known from here. However, the valves are not symmetric about the hinge line, although @Peat Burns suggested it could be a deformation. Any ideas are appreciated.
  9. Bivalves or brachiopods?

    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.
  10. Middle Devonian bivalve and gastropod

    From the album Middle Devonian in Central New York

    Gastropod: Bembexia sulcomarginata Bivalve: Nuculites oblongatus Middle Devonian Hamilton Gr. Marcellus Shale? Delphi Falls, New York Collected 5/16/20
  11. 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.
  12. Brachiopod or Bivalve?

    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?
  13. Bivalve fossil with pearl!

    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!
  14. 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
  15. Age is Miocene-Pliocene. Bryozoan is an immediate thought, but I'm pretty sure that they're quite rare post Paleozoic, and this kind of encrustation is very common in the locality where the specimen was found. Here is a picture: Bonus thanks if anyone knows with some certainty what the bivalve itself might be from the photo, though I doubt it.
  16. Bivalve or brachiopod?

    Hello, I found this really nice shell today. I've seen you can tell bivalves and brachiopods apart by symmetry, but I'm not sure with this one, I thought bivalve, but I'm not certain. Also if anybody could tell me the genus or species, I'd really appreciate it. Thanks.
  17. Pennsylvanian bivalve, Dunbarella?

    Bivalves always challenge me. If the ear (is that the right word?) on the left wasn't present, I would have called this Dunbarella sp. But the rounded ear doesn't match any species of Dunbarella I've seen. Maybe another genus, like Aviculopecten? Not sure. From Pennsylvanian black shale in Illinois. Thanks for any help.
  18. Help ID radial pattern

    Hello, I found this rock this morning behind my house and I'm drawing a blank as to what it could be. There are lots of brachiopods, bivalves and gastropods in this particular area but nothing that matches this. It kinda looks like an end view of a coral but I only find those about a mile away and not preserved like this. Any ideas would be appreciated. Thanks for looking. Northern Arizona, Mississippian, Redwall Limestone, Mooney Member.
  19. Super large bivalve/clam ID

    It measures 6 x 5.5 inches and is fossilized in shale. Thanks a bundles.
  20. Hi everyone this is matt again today in the creek I found a nice bivalve fossil it has been a few years since I have found one of these in my book it says this about the fossil lunulicardium eriensis small to medium-sized ,ovate to rounded triangular shell. Posterior margin straight: anterior margin rounded. surface with 60 to 80 very fine radial lines, and concentric growth lines making low undulations on the surface
  21. Hi, From time to time I found in Upper Campanian strata of SE Pyrenees some big steinkerns looking much like the American "Deer heart clams". So, my initial guesses are genus Cucullaea/Pholadomya/Arca, especially Cucullaea/Pholadomya royana, but my knowledge of bivalves other than rudists is very limited. Can anybody help? @Ludwigia @fifbrindacier Size of the biggest are 92 x 80 x 68 mm Center one is the best preserved (75 x 67 x 53 mm) : is Finally a different, smaller, specimen from same area and strata. I have no guess about it:
  22. Last weekend I got a chance to do some fossil hunting in a creek in Greene, New York. I am a unsure if the exact formation I was in but I know it was upper Devonian. Brachiopods were quite abundant, especially spiriferid ones. I also found a couple nice bivalves and some bryozoans/corals.
  23. A Mood Lifting Hunt

    I was able to get some much needed "me time" yesterday. With all the worries of the world I have been in a foul mood lately, but I am happy to report that my mood has brightened significantly. . There is nothing like crawling around on a road cut, and hunting fossils, to really lift one's spirits! I spent a couple of hours at an upper Ordovician road cut that has been on my list to check out. It is an exposure of the Grant Lake Limestone. Shortly after I arrived, I realized that I was in for a real treat! This particular exposure is more fossil than limestone. Brachiopods are everywhere! Vinlandostrophia dominate the exposure; with Hebertella coming in a close second. Other brachs are also found, but less abundant. Orthoconic nautiloid fragments are frequently found and bryozoan encrusting is a common sight. I also found a few gastropods, and one trilobite piece that I am excited about. Unfortunately I did not take pictures in the field. It was a conscious decision. I just wanted to enjoy my time, relax, and focus on the hunt. I'll get some next time as I will definitely be going back. I did take a few pics of my better finds at home. Enjoy! First up are the Brachiopods. I found some nice whole Vinlandostrophia, and Hebertella, and what I think is Rafinesquina ( @Tidgy's Dad ) . I also took home a few single valves for study of the internal structure. I think with a little bit of clean up these will look great! I was happy to find some orthoconic nautiloids. They have been sorely lacking in my collection. I will have to research what species are found in this formation to come up with an ID. I have a few ideas, but need to confirm. Here are a few gastropods and bryozoans. I can't resist the alluring whirls of a gastropod. They seem to be uncommon in the areas that I hunt so I grab them whenever I see them. I believe these are new species of bryozoa that I will be adding to my collection. Which is exciting! Here is a tril-o-bit that I found. I'm very happy with it. Typical trilobite fragments from this area are not usually identifiable. Except to say they are possible trilobite pieces. This is a cephalic doublure of an Isotelus. Thanks to @piranha for help with the ID. All in all it was a great time. I got to relax a bit, forget my troubles, and brighten my mood. I also added some nice pieces to my collection. It was a good day!
  24. New Member - Fossil Finds?

    Hi guys, I've found the website while searching for information about some possible fossils I found around where I live in over several years. I pictured those and hopefully someone here is able to put a name / species / period to them. I am not a collector. I have always been fasciniated by geology, rocks and natural history. Knowing what they are will be very exciting for me. Number 1 : I cannot reemember where exactly I found it but should be some 100km's inland from Aegean sea, close by an ancient city called Pergamon in Modern Turkey. I was simply walking on the foothills of the city when this strange looking rock caught my eye Number 2 : These two are from Palermo in Western Siciliy coast. They're both from a pile of rocks next to the sea. I wasnt't able to look around much to see if there are more rocks like them. Maybe they're carried from somewhere close by. Number 3: Found around 500-800 meters elevation somewhere in Central Anatolia, more than 300km from any modern sea (former Tethys Ocean?) very heavy and rocky at hand. Thank you in advance for your time looking at those. Some more will come soon
