  1. Hello! Here is a larger bi-valve - Is it Glycymeris sp.? As for the sand dollar - Any ideas? These are from the Aurora, North Carolina area. For the sand dollar - I would LOVE a GENUS - but will settle for Family!!!!! I would ALSO love a recommendation for a guide to this area.... I have the Lee Creek Mine articles.... I got a LOT of shark & ray teeth; THOSE i can do! MANY THANKS!
  2. Devonian bivalve (scallop?)

    Found in Arkona Ontario a couple weeks ago Devonian age Widder formation 38mm/1.5" across
  3. FOSSIL ID - N. Bulgaria - bivalve?

    Hello fellow fossilers, I am currently staying in northern Bulgaria, around 30km south of the Danube and there are a some limestone formations close to another local river. I found this fossil and am very curious to identify it! Perhaps it is some sort of bivalve animal but would be great to get some more information. Any thoughts?
  4. Hello all, Could anyone confirm or refute the identifications that I assigned to these?
  5. Location: SE Portage County, Central Wisconsin, USA. Geology: South Western advance of Green Bay Glacial Lobe. Former Glacial Lake Oshkosh. Niagara Escarpment Debris. My land. Ordovician onward. Is this a Straparollous? Holopea pyrene? Left some slightly blurry photos in to show cm size. The part in question is about .4 cm deep by 1.5 cm wide. There is also what might be a bivalve to the right of it, and maybe, chain coral. Dunno about what is shown on reverse. Looking for potential ID on all and anything else someone might see. Wondering if I should give this a toilet bowl cleaner (diluted) bath? The “snail” appears to be a quartz replacement. I did initial cleaning in Biz detergent for about 24 hours, repeatedly and several days in Oxyclean. Brushed after each soak with polyester bristle brush. Did not want to destroy the crystals above specimens, so avoided wire brush. Please let me know what you think. I also want to be sure I am using correct tags here. Since my land contains Ordovician onward period, should I just list Ordovician as the period? Also, how many tags are appropriate? Should they just be location found and potential period, or should they contain generic terms such as snail? If anyone else here is using an IPhone SE for photos and knows some ways to set it, I would be appreciative. I have been unable to figure out how to change the settings for photographing specimens. The camera has a mind of it’s own, and focuses on whatever it wants, even though I am doing everything that my provider told me to do to change the settings for macro. She said phone is capable of it, but required my digging into the depths, which I did. When I transfer photos from phone to computer they come up at 72 DPI. I am using Photoshop elements to change resolution and size, which usually causes photos to be blurry. Upon transfer, I have photos that are about 40 Meg. Once I adjust the size, they are down to less than 2 Meg. Then adjust focus and color cast to be as realistic as possible. I have figured out the best time of day for taking photos with my portable photo tent, LED light and natural light through patio doors. Also made a stable phone holder to help prevent blurry photos. Thinking there has to be an easier way, as each photo I post takes about 5-10 minutes total. Sorry, obsessive compulsive newbie here, lol. Thanks for looking and any comments appreciated. If my ID is off, no problem. top 3 3-16-4 3-16-3 3-16-2 3-16-2 3-16-1 3-16-8 3-16-9 3-16-10 3-16-12 3-26-6 shell side1 Fernwood Acres, on Flickr side 2 snail 1c Thank you.
  6. Bivalve from the Zandmotor

    Hi all, Found this on the Zandmotor, Netherlands. Most likely from the Eem Formation, Eemian, Pleistocene; 120'000 years old. Though most of it is not there, enough of it is present (such as the umbo, and one full side (which allows us to see what the general shape and size would be)) to be identified. I am thinking that it may be Politiapes ruditapes, but that is a wild guess. What do you guys think it is? Thanks in advance! Max
  7. (Modern) bivalve from the North Sea

    Hi all, I found this modern bivalve at the beach of Wassenaar (Netherlands) some time ago. What species is it? I am anticipating your answers with enthusiasm! Max
  8. Devonian brachiopod? From Resteigne

    Hi all, During my trip to the quarry of Resteigne, I namely found this brachiopod. Is this a Sieberella sp (as proposed by Roger @Ludwigia)? Because the fact that it is asymmetrical makes me want to incline to bivalve... But I'm not sure what kind of bivalve it would be then. Location info: Resteigne quarry, Belgium Jemelle Formation (mostly) Eifelian, middle Devonian; ~ 390 mya Thanks in advance for your replies! Max
  9. New Jersey Cretaceous bivalve? ID help

    I found this in a Cretaceous stream in Monmouth County New Jersey. I assume it's a bivalve but I couldn't find anything on in the NJ fossil websites. Anyone know what it is? Thanks! -Frank
  10. Trachycardium emmonsi

    Avery nice double valve cockle. Single valves are not uncommon at this site but double valvers are very uncommon for this species.
  11. Florida Bivalves

    Hello, I found this bivalve in the dredging materials found along the Orange River near Manatee Park in Ft. Myers, FL. I have consulted the Peterson book, Southern Florida's Fossil Seashells. It is a great book but there is no relevant fossils. Can someone help me identify this fossil? Thank you!
  12. Tiny Aptychus or Bivalve Steinkern?

    Yesterday I hunted an Upper Santonian Austin Chalk site in Ellis county between downpours of rain. This was my first time at the site. I was looking around a pile of rocks with some boulders mixed in and found this on one of the boulders. It is tiny, whatever it is, about 1 cm wide. Now I must admit that I am more familiar with the fauna of the Upper Coniacian Austin Chalk but to me this looks more like half of the aptychus of an ammonite than a bivalve. Since an aptychus was made of calcite I believe that it would be preserved in chalk, though the actual fossilized material is gone and this is just the steinkern of what ever it was. Here is the best picture that I have of it. Sorry that the quality is poor. I took it while I was at the site and I can’t get a better picture right now. Hopfully this will be sufficient.
  13. Hi all, Another very specific bivalve question for you all, this time regarding the freshwater species Corbicula fluminalis. So on the Wikipedia page: LINK, it says that this species is originally from Asia, but was introduced to Europe (and USA). Meaning it was brought here by humans. But, what is weird is that I found 2 fossil specimens of this species (as well as modern ones sometimes) here in the Netherlands! From the late Pleistocene, some 400K years ago. Long before humans had the means to introduce bivalve species like this in new places (and also long before humans came to the Netherlands in the first place). Oh, also, something relevant to take into account is that this species is NOT present in Eemian sediments! (late Pleistocene, 120k years) So how come that this species was "there" 400K years ago, disappeared, and then "came back"? The only thing I would consider as a solution is that the species went locally extinct (while still thriving in Eastern Asia) and was then reintroduced, but what is surprising is that I don't think that one single species could be alive in several different places far away from each other (the distance from Amsterdam to Beijing is nearly 8000 km!)... I don't think a bivalve species could possibly be present in such faraway places. So my question to you all is: what happened? How could it be on/off/on for this species in the Netherlands? Thanks in advance! Max
  14. The Cockles: Common vs Lagoon

    Hi all, So the Cerastoderma genus has (in addition to a few other fossil species) two extant species: C. edule (common cockle0 and C. glaucum (lagoon cockle). Both of these species appear (both fossil and modern) here in the North Sea, and their Eemian fossils are common finds at the Zandmotor. Now I have always been told, and read in most of my books, that the difference between them is that: -> if you draw a vertical line from the umbo downwards, C. edule is pretty much symmetrical while C. glaucum will have one side more stretched out. As can be seen in the picture above. Pretty straightforward. Plus, this is what I explained in one of my old Instagram posts: But, while searching a bit around, I just now saw on the Wikipedia website a picture of a symmetrical cockle that they claim is C. glaucum. And WoRMS also has some pictures of some more or less symmetrical cockles for the lagoon cockle! So I am very confused... What is the difference then between the two species? Looking forward to your answers! Best regards, Max
  15. Sunset shell

    This very nice and rare sunset shell was found in an extension of the Rotterdam airport, known as the Maasvlakte 2. One of the favorite bivalves of my collection Another name of this species is Psammobia fervensis, but this name is no longer accepted.
  16. Anomia bivalve

    An Anomia ephippium, found in a sandbank in the city of The Hague. This is technically an ex-situ find, because the city itself isn't really a location for finding fossils. The real location would be the Zandmotor or the North Sea; the bivalve here was brought with sands imported from the North Sea. This species is recognizable from the three muscle scars, the pearly shine and the weird little white thing in the hinge area (3rd picture).
  17. Arcinella cornuta

    Self collected at a sand pit in Columbus County N.C. Most of the time these are found as single valves with the "spines" completely broken off.
  18. Jacksboro, Texas bivalve?

    Jacksboro, Texas Lost Creek Dam area, about 1 inch long, Pennsylvanian, Graham Formation, Finis Shale. Need help with ID. Thanks in advance for any help.

  20. Texigryphaea marcoui bivalve a.jpg

    From the album MY FOSSIL Collection - Dpaul7

    Texigryphaea marcoui bivalve SITE LOCATION: Mills County, Texas, USA TIME PERIOD: Lower Cretaceous (100-145 million years ago) Data: Gryphaea, common name Devil's toenails, is a genus of extinct oysters, marine bivalve mollusks in the family Gryphaeidae. These fossils range from the Triassic to the Tertiary periods, but are mostly restricted to the Triassic and Jurassic. Both periods belong to the era Mesozoic. They are particularly common in many parts of Britain. These oysters lived on the sea bed in shallow waters, possibly in large colonies. The complete fossils consist of two articulated valves: a larger gnarly-shaped shell (the "toenail") and a smaller, flattened shell, the "lid". The soft parts of the animal occupied the cavity between the two shells, just like modern oysters. The shells also feature prominent growth bands. The larger, curved shell sat within the mud on the sea floor. These shells are sometimes found in fossil plates along with Turritella, clams, and sometimes sharks' teeth and fossilized fish scales. Its distribution is common in areas of both Europe and North America. A classic location to find these fossils is Redcar, on the northeast coast of England. There used to be a common folk belief that carrying one of these fossils could prevent rheumatism. They are also found in abundance in the state of Kansas in riverbeds and cliffs as well as the Big Horn Canyon of Wyoming and Montana. The benthic, free-living oyster Texigryphaea was the dominant constituent of many late Albian marine communities in the Texas and southern Western Interior regions. Large topotypic assemblages of three common lower–middle Washita Group species (T. navia and T. pitcheri in Oklahoma and T. tucumcarii in New Mexico) each display considerable morphological variation in valve shape and the proportions and expression of various features. Variation within an assemblage is partly due to ontogenetic changes but is mainly ecophenotypic, with local variation in nature of substrate, water turbulence, length of attachment time, and other factors influencing the final morphology of the mature shell.

  22. Neithea or Pecten Fossil a.jpg

    From the album MY FOSSIL Collection - Dpaul7

    Neithea (Pecten) Fossil SITE LOCATION: Coryell County, Texas TIME PERIOD: Lower Cretacious (100-145 million years ago) Data: Neithea is an extinct genus of bivalve mollusks that lived from the Early Jurassic to the early Paleocene, with a worldwide distribution. Neithia sp. are inequivalve. That means that the two valves are not the same shape, the right valve being strongly concave and the left valve being flattened or concave. Sculpture consist of alternating strong and weaker radiating ribs. Kingdom: Animalia Phylum: Mollusca Class: Bivalvia Order: Pectinoida Family: Oxytomidae Genus: Neithea

    Ilymatogyra ram's horn oyster fossil SITE LOCATION: Del Rio, Texas TIME PERIOD: Lower Cretaceous (100-145 million years ago) Data: The Gryphaeidae, common name the foam oysters or honeycomb oysters, are a family of marine bivalve mollusks, and are a kind of true oyster. This family of bivalves is very well represented in the fossil record, however the number of living species is very few. All species have shells cemented to a substrate. Shells are considered brittle, inequivalve, with the left, lower (cemented) valve convex and the right (upper, non-cemented) valve flat or slightly concave. Kingdom: Animalia Phylum: Mollusca Class: Bivalvia Order: Ostreida Family: †Gryphaeidae Genus: †Ilymatogyra
