  1. Devonian Identification Dilemma

    Recently I have taken interest in fossil hunting after discovering a plethora of fossils from some farmland in Southern Indiana. It is my understanding the fossils are from the Devonian period. My grandsons (5 and 6 years old) and I have collected several specimens I’ve the last couple of months. I have been searching the Internet for weeks trying to correctly identify our finds and just when I think I have something identified —I find other possibilities. I would like to make displays for the grandkids and label our other collections appropriately. I am in hopes this community would help identify the specimens, and provide advice on how best to label the fossils. I appreciate any assistance that can be provided. Thanks. —Bill Shingleton PS: All the fossils depicted are from Jeffersonville, IN.

  4. Hello all, I have a few fossils that do not fit into the ID categories of topics I have already created so I will post them here. This first one I have no idea what it is, it has an asymmetrical shape with a beak-like portion to the shell that curves to one side. It is somewhat similar to a modern slipper limpet. I don't know if this is a gastropod, pelycopod, or something else. I am not expecting to get a genus or species for this thing since all of the shell is missing but being able to identify it to some extent would be great.
  5. Today I joined a local club on a trip to a dolomite quarry (Ordovician, Galena Group) in northern Illinois. This was the first trip of the year as the rest have been cancelled. The quarry was quite massive, so social distancing was not a problem. We hunted in rock piles in the middle of the quarry (very far from the high walls) that were scheduled for crushing. It was quite a beautiful place. Besides some hammering, all I heard were large birds that were circling above. The fossils found here are pretty standard for the Ordovician rocks in the area. The Galena Group here seems to be a lot more dolomized than further north in say Minnesota, so most of what is found are molds. Fisherites were somewhat common. They were quite massive so I only took home a small chunk of one I broke up. The most abundant fossils were these gastropods, I think Maclurites. They were everywhere but rarely came out complete. Hormotoma gastropods were also present. I believe this is a cranidia of the trilobite Thaleops.
  6. ID help on gastropod fossil

    I currently have this fossil temporarily written down as Bembexia suclomurginata based off some pictures i’ve seen but i need more clarification. I’m not sure where it was found, the seller never clarified the location.
  7. Micro Gastropod

  8. Late Carboniferous Gastropod

    Possible ID of Trepospira sphaerulata from a local gastropod expert, but he isn’t sure. Similar ones in a group with original specimen at the right. Left is suspect of being related, but it might be.
  9. Gastropod / Unknown Bone

    Below is gastropod and was wondering a couple of things. Found NSR up from the Ladonia Park. What species to label it. Second though is it is heavy for its size. I know weight doesn't matter a lot but it is unusual. It is a different matrix from the normal NSR black or red gastropod steinkerns normally found there. Ok, the really unusual part it smells like metal. Like when you hold coins in your hand and they have the metallic smell. This has that smell and your hand smells just like it after holding. Maybe thinking to much into this but just is different. Bone fragment same location. Might be to worn to label.
  10. Hello, I would like to ask for opinions about this 5 mm "tall" gastropod. Its from the Langhian - Miocene (15 Ma old) "Florianer Schichten" of the Styrian Basin in western Styria, Austria (St. Josef, site Fuggaberg-3). Other molluscs at this site are Granulolabium, Terebralia, Anadara, Acanthocardia, tellinid bivalves, oysters, naticids, buccinids etc. Many thanks for your help! Franz Bernhard
  11. Crockett/Stone City unknowns

    Hello all! I made my first trip to the famous Eocene Texas location a few weeks ago and have a few things that remain a mystery to me. I have perused the forum and was able to ID most of my finds from jkfoam's informative replies and many topics from other members. However, several of the gastropods below resemble species I have already identified, but they're not quite the same, so I'm unsure exactly what they are. Not all the images have a scale, but they are all micro fossils under half a centimeter in length. Thank you in advance for any help you can offer! (1) I know this is an ootolith, but I cannot differentiate between the two most common kinds. Help would be appreciated, especially as I only have two of these guys and they are the same. (2) Initially I believed this to be an ootolith as well, but after cleaning it, I really have no idea. Image is front & back. (3) Here is another that I believed to be an ootolith but now have doubts about. Image is front & back. (4) This appears very crab-esque to me, but again, I have no idea. (5) Could this be Bolis enterogramma? I can't find enough images on the web to say I am confident with my ID on this one. (6) I have this (and many others) down as Polinices sp., however I cannot tell the difference between these and Neverita sp. so the ID could be incorrect. Could someone clarify the differences for me? (7) Mystery gastropod (two views; same specimen). (8) Another similar mystery gastropod (two views; same specimen). (9) This is one that looks similar to some I've already IDed, but just different enough to make me believe it is something else. (10) I believe these two are the same species, but when they get this small (some of my smallest; only a few millimeters long), I find it difficult to tell. For all I know, these could be ice cream cones.

  14. Urban Fossil ID

    Hi! First time posting! :-) I've been hunting around for "urban fossils" in my city. I'm really used to seeing rudists everywhere, and whenever I come across anything else (like a piece of coral or a gastropod) I get excited. Today I saw something I had supposed was a gastropod shell section (now I'm not so sure), but it has a peculiar design, and I wonder if anyone can tell me what this design is. It seems to be some kind of internal structure in the shell? I'm attaching two photos of a close up of two different specimens and then a broader picture of another part of the slab, in case anything else in there might give people hints. The photos were taken in Donostia, Spain. I can't really say where the rock was quarried, but I guess somewhere in Spain? I'd love to hear your take on it! (Both on the "internal structure" and what kind of creature this might be) Thanks :-) Elizabeth
  15. Folks, I found this fossil mollusk from a shale deposit in Northeastern Oklahoma. The shale is of Pennsylvanian age (probably Chanute formation), and contains other marine fossils. I would appreciate any help with ID. Best wishes.

  17. Gastropod or something similar?

    Hey again, this is a very tiny ~.5cm shell that I found some time ago at the regular road cut at the Lost River exposure of the Mahantango Formation. I would guess it’s a Gastropod or something similar but if it could be narrowed down any further I would be elated. Thanks guys!
  18. I’m almost done prepping this gastropod I found a couple weeks ago at the roadcut along Rickard Hill Rd. in Schoharie, NY, but I am unsure of the species. It is from the Lower Devonian Kalkberg formation.
  19. I am working again these days, but on Wednesday, I got off early enough that I made a trip to a creek in northern Hill County. Its limestone walls are full of fossils, but the limestone is very hard. It is obvious that I need to get better at chiseling fossils out of limestone. I could get lots of practice in this creek. Macrostrat shows the area where I was as being right on the border of the Fredericksburg and Washita Groups. The first thing I noticed about this creek was how many Gryphaea (devil's toenail) oysters there were. Most are pretty small, but they are everywhere. There are more of them in the creek than all other fossils combined, including lots of limestone pieces just full of small ones like the one in this photo.

  22. Comparing fossils

    I decided to do a little experiment. awhile ago, I went to the canyon in the Snake River, and I found a bunch of gastropod shells. Not extinct, these were not fossilized. I decided to bring some home and compare them to a fossil gastropod shell that I had. I am aware that differences and similarities vary by species, but I don't know gastropod species that well, extinct or not. Pictures are attached under a magnifier. The white one is the living, the brown one is the extinct fossil. Due to file size, I'm posting the fossil on a different post. I want to invite others to point out what they notice is different and similar about the living and extinct gastropods. (Besides the obvious fossil/non-fossil) I'll point out what I notice myself later.

  24. Hey all. Couple questions about North Sulfur River Tx. Why can I pull one gastropod that will be black (one species) and then within arms reach (another species) will be red? Both semi covered in the red matrix. Has anyone found a large complete red ammonite? I find pieces of large ammonites but always just pieces. I have found a complete Pachydiscus that is around 6 inches in diameter. That is the largest complete one I have found. Thanks for any help. Still learning this stuff.
  25. Hello, I found this very unusual seashell on a Tampa Bay beach, Florida. It measures 1 3/4" long by about an 1 inch wide with distinct whorls. It appears to be agatized like the coral I find and is translucent when held up to the light. I than noticed bubbles inside of it which must be water? I spoke to a mineral and fossil vendor and he said it was a enhydro and very rare. What do you think? How was this created and what kind of seashell do you think it is? Thanks! Lynn
