  1. I found this last year in north-central New York. It is from the Ordovician whetstone gulf formation and is about 1cm wide. I’m thinking it may be a crinoid calyx base but I may be wrong. Any help would be greatly appreciated.
  2. Hi, Looking for identification. It is the first hunt in a long time, and the kids and I were searching for shark teeth along the Calvert Cliff formation in Maryland. We found what we believe is a whale rib, but wanted to get some expert eyes on it. It is approximately 10” by 4” and 2” thick. It is dense weighing about 2 1/2 pounds. Almost has a “metal” fell to it. The shape just looks too unique to be a rock. We found it near a fresh fall section. What do you think it is?
  3. Today on a hunt in the lower devonian of new york, I found on of the most unusual piece and I can't decide if its bryzoan or possible placoderm.
  4. Plattsburgh Ordovician fossil

    A month or so ago I found these while trout fishing in a creek in the lower Champlain valley. I have no idea what they are, so any info would be very helpful. They were from Ordovician rock that was pretty barren except for a few brachiopods.
  5. Possible crab fossil/Fossil ID

    While rock hunting out on our local river the other day for jasper, agate, concretions, and petrified wood; my little brother came across a fossil that we believe to be a crab shell. I am quite the amateur when it comes to fossils but hope to increase my knowledge as I go along. If anyone can identify the species or anything else about this specimen it would be greatly appreciated. Our area is Northern Oregon if that helps narrow anything down. UPDATE: After a lot more research, I believe it may be a Macroacaena, but not 100% sure.
  6. What is it?

    The dimensions of the fossil are 1 cm x 0.5 cm. I can't figure what could be.
  7. Hello everyone, found this hallowed out bone in Big Brook nj. It is rock solid and when I did the burn test on it, it remain unscathed with no smell so I definitely think its fossilized bone. I'm not to sure if it's identifiable as is, any thoughts on this one will be appreciated.
  8. Big Brook Jaw Section?

    Hello everyone, I was in Big Brook nj for a little while today and found this interesting bone. I'm not to sure if it's identifiable but it does remind me of a jaw section like a mosasaur or croc. Any help will appreciated, if I missed an angle or need additional pictures do let me know.
  9. Stone Fossil ID

    Hello everyone, Does anyone know what it could be? ... is this Geologic or fossilized?, if it’s fossilized, what did it come from? And if so would it be a finger, or toe bone ? Found in the country of Mexico, specifically in the state of Guerrero, in a limestone mountain near some volcanic area or with tectonic plate activity, because there is quartz in the surroundings. I have never come across anything like this and around the discovery there are some pieces like these with some similar characteristics Thank you!!
  10. Newbies looking for Fossil identification

    Hi There Myself and my two boys have just started fossil hunting. We have no clue what we are doing ,but it's exciting and the boys are ecstatic about doing this and very eager to learn. Please help with our first identification. This rock is used as an artificial river bed filler. We don't know where it was quarried ,but are keen to know what fossils are inside. I'm assuming some type of sea bed coral or tube. PS: Will return rock when identified.
  11. Unknown vertebra?

  12. Hello everyone, Does anybody know what this might be? Found in a stream in the forest in the region of calvados, Normandy,France. I have never found anything like this. U cant really see the details of the thing sticking out of the spongelike matrix in the pics cause my camera is not the best. But here we go:
  13. Weird Wisconsin Fossil

    Recently I discovered the joy of fossil collection and hunting ( thanks Covid19 , you can go away now). I have primarily been finding things in eastern Wisonsin and from the Silurian reef that used to be here. A couple of days ago I found an area with some weird looking fossils. They almost look like tentacles or worms . I am really unsure what they are. Any suggestions or help would be greatly appreciated. I am a novice at this but have been reading up and educating myself as much as I can . Thank you !
  14. Does anyone know what this might be? The surface of the rock is flat.
  15. Fossil plant needs ID

    Fossil accidentally found in a brick that broke open. About 4cm × 6cm width and 15cm length. All 3 pieces slot together. Would like to know what it is, thanks!
  16. Potential bone fragment (?) fossil ID.

    Hello, everyone! Welcome to my first post! After lurking for a while I’ve finally created an account because I have what I think is a fossil but I’m unsure of the ID. i bought this particular specimen from a rock shop in South Dakota, USA about five years ago. The guy who sold it to me said it was a section of mastodon bone, but obviously I don’t fully trust what comes from a guy at a rock shop. I am about 95% confident this is actually a chunk of fossilized bone, however, as it’s weighty, passes the lick test, and the internal spongy structure of bone is visible on either end. I apologize in advance as the tape measure shown is in inches. I could not find a metric ruler or tape measure anywhere in my house. At its widest points the specimen is about 13.3 cm by 8.5 cm by 3.5 cm. I know most of this info is vague and I don’t have an exact location for the original collection. Any help with even a broad ID for type of bone (if it is one) or what animal it could belong to is appreciated. It may also be worth noting (as it is not totally clear from the pictures) the longest edge of the fossil is relatively flat and smooth, I mention this because I feel it may be an important diagnostic characteristic. Thanks!
  17. Hello, I found this fossil last spring break, in Coahuila, Mexico. It comes from the late Campanian (73-71 Myrs) Cerro del Pueblo formation. I found several fossils at the same location where I found this fossil. Some of the fossils I found include Cerithium snails, several species of Physidae freshwater snails, Inoceramus sp., petrified wood with teredolites, ammonite fragments, a caudal vertebra from a Hadrosaurid, and plenty of dinosaur bone fragments. The formation is a mess, it’s composed of layers that were deposited in marine, and terrestrial environments, as well as rivers and possibly swamps. Even though I’m very knowledgeable of the formation, and the fossils that have been found there I still have no idea as to what this specimen is. My best guess at the moment is that it’s some type of plant material maybe a fruit or a seed. There have been numerous plant fossils found at the formation, including fruits. I also think this could be embedded in a coprolite, with the rounded object being embedded in it. Let me know what you guys think about it.
  18. Help with id on some bones please.

    Hello everyone, During this time of pandemic lockdown (since March 17 here in france) I take a walk in the forest sometimes since I cant go to the beach to search for fossils, im in the area of calvados about 7 km from the coast and these are some of the things I found the other day walking along a dried river in the forest. I believe no.1 is a piece of petrified wood, it's heavy and have very well preserved details that look like wood. The other pieces I'm not sure, they are all heavy like rock and in some of them you can see rock. But I have no idea what they are. Size of the wood piece is 15 cm for scale. Thank you in advance for your help,
  19. Peace River fossil

    Peace River April 13, 2020 Found near Wauchula, Fl. I 'd appreciate nay help identifying this fossil? Thanks Steve
  20. Textularia? or what?

    This sample was stained by rose bengal solution. it was sampled from the intertidal zone in Apo reef natural park in mindoro, Philippines, around >5m depth. I'm confused on what species is this. I have no other pictures since we are under a community quarantine here in Manila so I have no access with my microscope.
  21. No clue what this is, but it's got teeth!

    Hi everyone, just came across this site trying to figure out what I just found. Discovered in the salt water in Chatham, MA, US. I have no clue whether this is current or ancient, terrestrial or marine, etc. You can see the next set of teeth still in the bone. It's about 10 cm long, and the largest tooth is about 1 cm wide.
  22. Fossil id

    I found this beautiful one today at the beach. I do think it looks a lot like a jellyfish, but I know they are pretty rare so it’s probably not. Would really like to know what you think! Thanks for your time
  23. Coprolite or meteorite?

    Hi, I found this in a creek in Austin. It's very dense and has lots of smooth bumps. I was wondering if it was maybe Coprolite or maybe a meteorite. I tested to see if it was magnetic but I couldn't really feel anything. It's about the size of a golf ball. Can someone help me id this? Thank you!
  24. Are these fossils?

    So...my daughter, budding paleontologist, purchased these via online as fossil tidbits and teeth. Have we been had?
  25. ID of goniatites / ammonoids

    The Namurian cyclothems in West Clare, Ireland originate in an environment of delta systems which deposited sediments in an offshore basin (Clare Basin) and are referred to as the Central Clare Group. There are five cyclothems comprising marine bands (conventionally considered to form the ‘base’ of each cyclothem) and upwards coarsening fine-grained and sandstone sediments. The five cyclothems are named (from oldest to youngest): Tullig, Kilkee, Doonlicky, Cyclothem IV, and Cyclothem V. The marine bands contain - among other fossils - index fossils in the form of ammonoids (goniatites). These index fossils are used to determine the stratigraphy of the cyclothems. Central Clare Group marine bands and goniatite index species (youngest at top) Cyclothem V top - R2c1 - Reticuloceras superbilingue alternatively Bilinguites superbilinguis (Bisat, 1924) Cyclothem V base - R2b - Reticuloceras wrighti alternatively Bilinguites metabilinguis Cyclothem IV base - R2 - Reticuloceras bilingue alternatively Bilinguites bilinguis (Salter, 1864) Doonlicky base - R1c - Reticuloceras reticulatum Kilkee base - R1b3 - Reticuloceras stubblefieldi alternatively Phillipsoceras stubblefieldi Tullig base - R1b2 - Reticuloceras nodosum My problem is the differentiation between these goniatite species in the field. Some of them look quite similar - to me - and in addition, they are preserved as very compressed, often crushed shells. At one location, they are firmly incorporated into concretions which appear to have dried out at some time, showing polygonal cracks filled with calcite; very handsome but even more difficult to identify. Under this topic, I have grouped images of goniatites by location and added information regarding the goniatite species recorded on the Geological Survey Ireland Spatial Resources website for each location. Any help with identification is greatly appreciated! So the first batch of images from Seafield beach, near Quilty village, County Clare, Ireland is in my collection 'ID of goniatites / ammonoids - Seafield'. The Geological Survey Ireland Spatial Resources website records Reticuloceras superbilingue, Reticuloceras bilingue and Reticuloceras stubblefieldi for this location. But which is which in the images?
