  1. 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.
  2. 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.
  3. 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
  4. 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.

  7. 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
  8. 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.

  10. 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!
  11. 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.
  12. 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.

  15. 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.

    Diaphorostoma depressum Lower Devonian Helderberg Gr. Kalkberg Fm. Rickard Hill Road Schoharie, NY Collected 5/31/20
  17. 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.
  18. 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

  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. Ammonites and gastropods.

    Hello, sorry to be a pain with all these IDs. I thought itd be easier if I just put all of them in one post. All were found in Northamptonshire, UK. Which is mostly Jurassic in age. Sorry there's no scale, I couldn't find my ruler anywhere. I'll have to upload more images below this. Its been quite some time since I've found ammonites. The land had just been rotavated, and aside from the ammonites, I found some Bivalves, and two golf balls buried. Thanks. These are the first two ammonites, I tried to ID them, but they are incomplete, so it was a difficulty, the closest I think it looks like is Harpoceras. Each are about two centimetres (about 0.8 inches). I saw a neighbour had a very similar rock with two larger ammonites on them that was being used to hold a fence down.
  25. Gastropod from France

    Hello all I found this gastropod about 18 months ago in the Provence province in France. The spot should be Cenomanian in age. It's about 1 cm wide. It's not the best picture but the fossil itself is not all too well defined. Any ideas? Thanks in advance
