  1. Location is in Missouri The area is dated to the Pennsylvanian Formation: Iola limestone formation Subformation: Muncie Creek Shale Member Hello and happy valentines day ! I was re-examining my old collection of Muncie creek shale nodules and found these peculiar specimens Originally I posted an image of one of my larger heart shaped fossils in my member's album, where someone mentioned it could be some sort of bellerophrontid gastropod. But now that I have found a second more complete specimen, I think it was time to ask fossil ID to get more eyes and possible identifications. Specimen #1: My newest specimen and one I found to be heart shaped This specimen also has some weird sphere like structures beneath it so I took more up close images of it For this specimen there are no other parts of this nodule as I found it fragmented. Specimen #2: (2.3cm) My largest one and the one possibly identified as a bellerophrontid gastropod Size comparison between this specimen and the smaller specimen Specimen #3: I think this is just a regular old brachiopod or bivalve but I just wanted a confirmation on such! (The individual is 6mm long) It also died near some fish remains Both halves of the nodule Right side of the nodule

  4. Misha

    DSR Gastropod

    From the album: Misha's Middle Devonian Fossils

    Mourlonia lucina? Gastropod from DSR I stumbled upon in my weathering pile. Doesn't match the usual Glyptomaria found here so it caught my eye. I'm not too sure on the ID as I couldn't find any images online of similar specimens, so had to go off figures from the field guide. Givetian Windom Shale Moscow Fm Hamilton Group Deep Springs Road Quarry Lebanon NY

    Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.
  6. Does anyone recognise this tiny silicified shell? It's about 2mm long. I haven't seen one like it before from the Carboniferous. From the Great Limestone (upper Mississippian, Pendleian Stage) from Weardale, Co. Durham, England. From a piece I've been dissolving in acid, containing silicified brachiopods, gastropods etc. It starts off with an open helical spiral (3rd photo) and then straightens out. It also has clear annular ribs. Although the preservation is imperfect and sugary, I'm sure it's shell replacement rather than internal mould, judging from other fossils in the pece. The various serpulid-like gastropods and microconchids I've come across elsewhere don't have the regular ribbing.

    What kind of gastropod ?

    Hello, I got this gastropod, not sure if its fossil tho, gifted by my neighbour after her holiday trip to nothern france. No more location was named, and I really want to know the species. @Coco, do you have an idea ?
  8. My son found this on the shore of Presqu’ile Provincial Park. Is this a fossilized sea snail?

    Gastropod help ID

    This was found in the Carboniferous limestone of the Malahide formation , east coast Dublin Ireland,
  10. From the album: Missouri Trilobites

    Found this beauty on a trip near Nodoway county along the Platte River. This most likely belongs to the Kereford limestone member of the Oread Limestone formation. The limestone itself is oolitic and can be seen in the missing/glabella cast of the trilobite. It sits atop a possibly a very thin to nonexistent layer of the Heumader but definitely atop a larger exposure of Plattsmouth with beautiful brachiopods with spines. This trilobite is definitely a rare find for the area.
  11. I was lucky enough to pick through some matrix that’s super fossilferous, thanks @JamieLynn gastropods are one thing I struggle with some much when it comes to ID. I’ve put my guesses down below but would appreciate any help anyone can offer. Thanks in advance! 1. Botis enterogramma or Paeudoliva vetusta 2. Bonellitia paritis 3. Architectonica elaborate 4. A. bellisttiata 5 and 6. Not sure 7. Meselia claorborneensis 8. Terebra texana 9. Hastula houstonia 10. Turritella nasuta 11. No ID? 12.Hesperiturris? 13. Eosurcula moorei 14. I really can’t tell any like this apart. 15. Ancilla staminea 16. Too broken ? 17. Conus tortilis 18. Not sure. 19. Buccitriton trxanum 20. Ficopsis nucleoides
  12. I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!
  13. Hello everyone! Recently, I found a gastropod imprint with a weird zig-zag pattern in the Cretaceous Merchantville formation (hard pan) of New Jersey. After showing it to a few folks, it was suggested that it may maintain its original color pattern. We aren't aware of this occurring on the Atlantic Coastal plane so I wanted to get more opinions on it and if it could be that. Thanks for your time! Frank
  14. The Paleontological Society of Austin gets to go to the Lake Jacksboro site once a year.. Dallas Society also goes out there, so we try to make sure not to overlap, but surprisingly, the site is so productive, there's always great stuff to find! The Carboniferous Period- Pennsylvanian site is well known for its wide variety of fauna. I've been out there a dozen times and almost every time I find something new! It may seem a bit desolate, but it's worth the trek! My first happy find was a crinoid calyx. As with most Pennsylvanian sites, crinoids are prolific. But I've not found much complete crinoid material...but this time, I found two! Another fossil that is a special find out there is a little thing called a Rostroconch. It was originally thought to be a bivalve, but has been given it's own class. This is only the third one I've found. They are not common. Another of the most sought after fossils there are the Goniatites and Nautiloids. The big ones are rarely found whole, but you can also find tiny ones in the micro zone. Gonioloboceras and Tainoceras are the most common largeish ones and I have yet to find a GOOD complete one of either. I have found a few Gonioloboceras what were either almost whole or were so weathered that they look like zombies! This time I THOUGHT I had finally found a good complete one! This is what I saw and my heart did a flip flop! Unfortunately when I cleaned it up, the center was eroded but I actually kind of like the other side, even though it is weathered and a little "zombified" at least it's mostly whole! But the zigzag sutures are amazing! I found a few smaller ones in the field, but the big payday was the two 5 gallon buckets of micro matrix I brought home with me from the micro zone and found a PLETHORA of tiny goniatites this time! Top Row- R: Glaphyrites millsi C: Imitoceras grahamensis L: Neodimorphoceras texanum Bottom Row: Prouddenites grafordensis C: Wiedeyoceras pingue L: Unknown But this is kind of fascinating - it was encased in a little bit of matrix, so I tried to break it off but ended up kind of breaking the whole thing. But because of that, it released the tiny interior! Peritrochia sp. I certainly wish it were whole, but it's still fascinating to see the interior. Another new find was this little Brachiopod Fimbrinia - I'd been looking for one of these for a while and finally found one! Another nice little Brach with a surprising pearlescent surface - Kozlowskia splendens Also found this little Orbiculoidea missouriensis Here is an unusual coral called Palaeacis perpendicularis Found lots of cool gastropods, but my all time favorite is Cymatospira montfortianus I am already excited about getting back out there, maybe in the Fall because Texas summertime is NOT when you want to be out on those flats!
  15. Some examples of fossils found in the cliffs and boulders of Malibu Creek Canyon Narrows. Oyster Bed and Moon Snail and Turritella Shell Fossils. The species guess for the Oysters based on research is Ostrea (Pycnodonte) Howelli, but I am not sure. Probably Eocene period fossils. Maybe Miocene. Nice area of Malibu creek in the Santa Monica Mountains but difficult to access.
  16. Many earlier Pleistocene period shells (~1M yrs ago) from a site inland from Rincon Point in Southern California. Got some great ID suggestions from various people on these and was informed that the shattered Trochita (Limpet like slipper shell) is probably one of two undescribed extinct species known from that deposit. Useful ID references for the area: Phill Liff Gieff, Frank Pesca Jr, Thomas Everest, and others https://inyo4.coffeecup.com/santabarbara/santabarbara.html Cyclocardia / Coanicardita - Grant & Gale (1931) Antiplanes - Raymond, 1904 Cantharus fortis (P.
