  1. Not sure about this one

    This belongs to a friend of mine. Never seen anything like it myself, so I have no information for now. He thought it might be Halysite (chain coral).
  2. What are these?

    Good morning. Can anyone tell me what these are? I just need a good starting point for researching.
  3. Unknown Acquisition

    I bought a small fossil collection that contained several Erismatopterus levatus and it also contained several unidentifiable and unlabeled items, in particular this piece. It reminds me almost of a placoderm skull plate, but I honestly don't have any idea. There's area of denticles on the side of the fossil.
  4. Hello all Since I can't go to school for a couple of weeks I have time to catch up with some ID's. Most of these plants and pieces of wood have been in my collection for years, thinking it's impossible to ID these because of lack of location. All of these come from old collections without labelling. I know next to nothing about plants or wood. 1: No location at all. Piece is about 10 cm wide. I am not 100% this is actually wood and not just a mineral, but I think these are growth rings. 2: This piece has been in my family for the past 3 generations, without any info. About 10 cm wide. 3: Nothing is known about this piece. It's very heavy. About 16 cm. 4: Also nothing is known about this piece. I think this is called Calamites, but again not sure. It's very long (I have a joining piece so total length is about 15 cm) and thin. 5: Also no location. Largest fern piece is about 7 cm in length.
  5. I am hoping someone can help me with this large unknown trilobite. It was given to me many years ago (late 1980s) by my father, along with some other trilobites and other fossils, as a Christmas gift. He acquired the fossils from a member of the local fossil club (Delaware Valley Paleontological Society) and most were carefully labeled, but this one was missing its label. It is a large, partially enrolled trilobite (15 cm from "nose" to tail if unrolled and 6.5 cm at the widest point); there are small bumps down the middle of the thorax and on the glabellum. It is on a chunk of matrix that lets it stand on its own, and it is a cool display piece. But looking at it closely, it looks...wrong. There's not much detail on the eyes (which seems to be usual in fakes, but can also mean a poorly-prepped real specimen) and overall it just looks wrong, in a way that I can't quite articulate (which again could mean fake, or badly-prepped but real). So, my questions are: 1. Is this, in your opinion, a real trilobite that was badly prepped, or a fake? I would appreciate if you can point out specific features that lead you to your decision. 2. If it is real, can you hazard a guess as to genus/species, and (this is a stretch) where it might come from? The scrape marks on the matrix resemble what I've seen on some Moroccan specimens. However, the other trilobites it was sold with are all from the United States, except for one from Pakistan (!), if that means anything. I think this trilobite resembles Calymene in general shape and size, but I don't know much about trilobites (if that wasn't already obvious) and I could easily be wrong. Thanks in advance for any help you can give. Let me know if additional photos would help- my photography isn't great, but I'll do the best I can.
  6. What is this?

    There’s absolutely 0 information about this 14” bone at all, as it’s from an estate sale. Does anyone somehow have ANY ideas what it might possibly be, just by visual clues? Mesozoic? there’s a rattle when it’s shaken, which might somehow help age it, based on mineralization, I dunno(if that’s not at all likely for something that’s been mineralized for over 65mil years, as opposed to less than a million?). I love it because it is absolutely COVERED in predation and scavenging marks on both ends, and more, but I wouldn’t really want it if it was a post Mesozoic mammal. Any thoughts anyone might have would be greatly appreciated!
  7. Capitola Fossil ID

    Recently stumbled across this, possible, fossil in Capitola Beach, CA. I found an assortment of fossilized shells but was unsure of this find. Anyways, I’m new to fossil hunting and don’t have an exceeding amount of experience, so any knowledge regarding what this could possibly be would be helpful. Thanks!
  8. Green River Fish Amia Head???

    Hello everyone, I'm looking for a second opinion on this piece, a fish head from the green river fauna, while I believe it maybe Amia due to comparisons I'm not to confident, any help/guidance is and will be appreciated.
  9. What are these?

    I have yet another group of unidentified fossils from an estate sale. They all appear to be the same type/species but of what? Can anyone help?
  10. Something special?? ID request

    Good morning folks. I have another (yes, another) unidentified fossil in dire need of an identification because it's getting lonely in that drawer. I believe this was a flea market buy (many years ago) without any information. Can anyone help?
  11. Snail? ID request

    Good afternoon folks. I have an item desperately requiring an identification so it can be placed on my display case. It was an unidentified find at the 2000 Tucson Gem and Mineral Show. Can anyone help?
  12. Little Urchin

    Hi, i had this little urchin from @Kane, he doesn't remember where he had it. It is 1.8 width and 2.2 hight.
  13. Roadside find

    A friend found this on the side of the highway in James City NC, any ideas. I told him I didn't think it was fossil but I couldn't identify it. He only took this one photo.
  14. What are these fossils of?

    Hi Everyone. My son found a couple of what looks like fossils while we was a walk. Could you help in identifying them? Are they fossils?
  15. Ammonite species ID help

    Good evening folks. I have an unidentified ammonite from the Tucson Mineral Show, that's all the information I have. Does anyone know what the larger species is? I believe the small, white item was glued on.
  16. acorn husk? Or coral/bryozoan

    Lost all my documentation on this item. If I remember correctly it was listed as an "acorn shell?" Is it? My guess is coral or bryozoan. Help please.
  17. Lobster???

    Can anyone verify my analysis (?) of this specimen? It was part of a unidentified lot sale.
  18. Fossil found at beach?

    Found this at a beach in south texas, I have no idea what it is.
  19. Bryozoa, Myriapora?

    №1 Found this fragil formation on the right bank of the Dnieper river, Ukraine, Kherson region. Look like this Bryozoa.
  20. Hi people. I am an amateur fossil hunter and I have come across this flint on my local beach. I don't expect it to be anything special but I'd like to learn more about it if you all would be kind enough to share some of your hard acquired knowledge. Unfortunately I know next to nothing in regards to the specimen so I'm relying on you guys to give me a start. Located on a the Sheringham, Norfolk, England beach after some large stormy seas Other common finds in this area are belemnites but of a orangery brown colour I hope this is enough to give even a brief idea Many thanks in advance for any information
  21. Bone unknown

    I'm not sure what kind of bone this is. I found it in Gatlinburg on the side of the mountain by a hwy
  22. Unknown fossil

    Buddy found this by his job. Wondering if anyone can identify it
  23. Going through last year's finds I found a few things that I don't recognize. All are from Pennsylvanian marine limestone. The first few all appear to be fish material of some kind. I find plenty of chondrichthyan teeth, but none of these look like any teeth I've seen, although they may be partials. Possibly some kind of bony fish scale? All images were taken under a microscope, no scale cube but they all are about 1/2" at the widest point. #1) #2)
  24. Very strange bone, Lake Waco

    Found this very very strange bone on the banks of Lake Waco. Any ideas?
  25. Plant? shell? or mineral?

    Found North of Houston Texas USA in gravel load from Brazos River at first glance it seems to be a shell like pattern on the stone {why I picked it up} but the pattern seems to be the whole stone so thought perhaps compressed fossilized plant concretion? possible fossil wood? pulled out my macro camera and studied further....now I am stumped more photos to follow.....
