    Tamiami bivalves help needed

    Well so much for getting distracted again...Uggh! I need to pay attention..Anyways, I just realized I created an earlier thread for a gastropod that I was labeling as a bivalve.oops..I also do need help with actual bivalve IDs....both are from APAC spoils Sarasota County. Possibly Beds 10 or 11 lower Tamiami formation. Thinking the first one is a Chama. Matrix removal has been a bear on these.. And the 2nd I was thinking it might be Marvacrassatella but thats just a guess. I'm going to consolidate the exterior hopefully this week and then separate the valves to get a look at
  2. Hi, I have found a place .. there is a Czech Cretaceous basin and there is an abundant fossil bivalve Innoceramus - But several species ( Inoceramus lamarcki (PARKINSON), Inoceramus cuvieri SOWERBY, Inoceramus inaequivalvis (GÜMBEL) ) and I do not know what key to follow in their determination. Please advise, or I would like to ask what kind of photo is it?

    Bivalve ID help

    Found in the Mount Laurel formation of the C&D canal Delaware. It looks like a modern day razor clam. Does anyone know the genus of this fossil?

    Jingle shell?

    Are these both Anomia sp.? Found in the Mount Laurel formation of the C&D canal Delaware.
  5. SharkySarah

    Is this a fossil clam or modern?

    I found this at the Mount Laurel formation at the C&D canal Delaware. Wondering if it’s a fossil and if it is, the scientific name.
  6. Hello i found these two fossil bivalves on opposite sides of the globe the one on the left was found in Montreal Canada and dates back to the late Jurrasic to early Cretaceous and the one on the right was found in the deserts of Riyadh Saudi Arabia and date back yo mid late jurrasic this is really incredible seeing how this species lived all over the earth just wanted to share this please share your thoughts thanks!!

    Bivalve from Morocco for ID

    Hello! Please help me identify these bivalve fossils from Morocco. Unfortunately, the age is unknown. Thanks in advance!

    Inoceramus or no?

    In my amateur collection there is such a run-in bivalve from the Picardy cretaceous deposits (France). It was identified primarily as Inoceramus concentricus. Is it correct?
  9. This is a 55lb rock my family found in a stream bed on a local hike in Southern California. Any idea what we've got? We are speculating some of the shapes look like worm burrows? Any information would be greatly appreciated! Thank you!

    Carboniferous Shells in Shale

    Hi! I was collecting plant fossils and found these shells. They are Pennsylvanian (Carboniferous), Conemaugh Group, Glenshaw Formation. I don't know what they are. Any help is appreciated, thank you.

    Late Ordovician, Brachiopods and Bi-valves

    I like the natural color of this red shales and sandstones formation

  12. Hello together, a friend of mine found this beautiful Myophorella in Portugal, I do not have any Information about stratigraphy except that the genus is jurassic till cretaceous. I think the ID to genus of the big bivalve is unquestioned (although a species would be nice.) What I wonder about are the little bivlave-like things clinging to the shell. To me they look more like epibionts than random taphonomic guests, they also look like tiny bivalves. Maybe young of the same species ? Did they grow in that way? I Havent found clusters of Myophorella in a picture search.

    What is this bivalve fossil species?

    I don't know whether this species is trigoniid or nuculanid bivalve. This fossil was found by me during fossil hunting at Frick, Switzerland with my family.

    Triassic fossil?

    Triassic scute, shell or paper weight? Found roadside with mixed road stones in NJ midway between Flemington and Lambertville Rt 202. This is part of the Newark supergroup sedimentary rock deposited during the Triassic period. I can't put this down because it feels biological not geological. All help greatly appreciated. My first post.

    ?Cyrtodontula compressa

    From the album: Bivalves of Platteville/Decorah Formation Minnesota

    Whitella is an invalid genus name - all specimens once called Whitella is in Cyrtodontula. Found in Decorah shale - the largest uncommon bivalve I have ever found in Decorah Shale as of 2021. There could be others since all bivalves are listed as uncommon to rare in Decorah shale. It could be my bias but oddly enough I only find mold impressions of this one (all 3 individuals) as negative molds in limestone without any hard shale encrust in the hollows. Trying Paint to show outlines - strongly resembles modern Anadara notabilis in general shape for example - its NOT related to Anadara. I'm on

    Deep Springs Road fossil IDs

    Hello friends! I've had some time to sort through, organize and take photos of fossils from my recent trip to DSR. I have also attempted to ID some of my finds using Lindsey's Devonian Paleontology of NY but have found doing so with the bivalves especially difficult, I'm not sure if that is up to me not having experience with then, them being generally harder to differentiate or a bit of both. Starting off with the lophophorates: 1. This brachiopod is a Chonetid, I initially just thought that it was Devonchonetes which is common at the site but looking closer it looked much more

    ? Bivalve

    Hi friends, I went to Marrat formation area (toarcian) to the west of Riyadh and found many? Bivalves, they are of varies sizes, it is internal mold, what sp. Is it?
  19. Hello all! This is a little photo project I've been working on for a while. When I first started Fossil Hunting I was content to collect whatever. Then I was excited about Identifying what I was finding. The education continued and now I work to identify the geological formations I am collecting in and am able to know what fossils to look for in what areas. The Pocket Texas Geology website is invaluable for finding out the formation of a specific area (while not 100 percent accurate, it's pretty good). So I wanted to create a post that would help with Central Texas Cretaceous Fossil Identific
  20. So, the part of creek this came from is composed of QT, QAL, and antique glass it seems. There are plenty of fossils too, when I washed out sand from this bottle the little shell was left, and I have tried to get it out but afraid of breaking it. All the recent shells in this creek are from Asian clams and mussels, from what I can tell this looks more like oyster shape. Got the best pictures possible through the pitted glass, so could this be a fossil?
