  1. Unidentified Fossil

    Series of tubes... maybe an insect colony?? A family member, who studied geology, left me their collection and I am trying to identify some of the fossils & minerals! Thank you!
  2. Coral or stromatolite or?

    Had this for about 10-15 years and can't seem to nail a positive ID on my own. Saw one similar to this in the group recently but can't relocate it. Does anyone know what it is?
  3. Three Unlabeled Trilobites to ID

    Being stuck at home has given me the opportunity to rummage through my fossils. I started with my trilobites. Weeded out three containers of Isotelus partials to give to the local sand pit. But I found 3 unidentified trilobites tucked in with the Isotelus for some reason.. Any help at IDs is appreciated. 1. Gerastos?? I think this was a gift to me many years ago. 2. Thaleops? Though I considered Illaenus or even Bumastus. The matrix looks like the Platteville, Ordovician 3. I have such difficulty with "rollers"! Thaleops? Matrix looks like the Galena, Ordovician that I frequent.
  4. Totally Odd Fossil? or Burrow????

    I picked up this rock while exploring a few weeks ago and noticed what looked to be an imprint of a crinoid stem in the rock. For whatever reason, I threw it in my bucket. At home, upon further examination, I came to a conclusion that this was not a crinoid imprint and was perplexed as to what it was. As you can see above, there was a big crack in the rock, self induced in order for me to see deeper into this. Here is the specimen after the rock was chipped away. The "lines" fade away as one goes deeper into the matrix until the surface becomes smooth. Next are views of the piece removed showing a tubular structure that is ribbon like, twisting and turning. Finally a few close ups of the ribbing in the initial picture. Leech like is how I would describe this, though I am aware, this is NOT a possibility, only mentioned to provide a mental thought while the images are examined.
  5. Pseudozygopleura species?

    Good evening folks. I have an item from the back of my "unidentified" drawer that I originally thought was a Pseudozygopleura species. I am having doubts because of the "twist" of the shell going 180 degrees in the opposite direction. Any help is appreciated.
  6. I have become the owner of these bones?

    Hello my friends father who was a surgeon passed away recently and after everything was finalized I inherited you could say a bunch of different fossils and stones. These were in a box I have about a hundred more pieces some big some small of what appear to be bone? Or maybe a tree or plant but I think bone. I cant tell you were he found them but he did dig them up himself and his daughter thought it might be at or around the ocean probably pacific that these were found. However she couldn't be certain. Please help!?
  7. A Novice Asks: Is This a Fossil?

    Hello everyone! My name is Patrick, I am new to these forums, and have next to no knowledge about fossils. I just found an interesting item today on my farm in Wayne County, Ohio, and was wondering if you could please help me. If it is not a fossil, please forgive me, I would like to learn more about the subject, and figured this would be a good way to start. Anyways, I was walking the bed of my creek, and I noticed what I thought to be a large bee hive stuck in the clay embankment. Upon further inspection, I noticed that it was solidified and made of rock, and the “combs” were more cylindrical than hexagonal or octagonal. I wondered if this is a fossil, and whether or not it might be coral? Any help would be greatly appreciated! I did my best to follow the photo guidelines, and the bottom of my tape measurer is in cm, for those of you whom may be outside of the U.S.
  8. UK Ichthyosaur or Pliosaur Tooth

    Hello, I recently got a hold of this tooth from an old collection in the UK. I am unsure if this tooth wouldve come from a ichthyosaur or a pliosaur since the root is absent and I'm not expert in this material, so any feedback that help figure this tooth out is appreciated.
  9. 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).
  10. What are these?

    Good morning. Can anyone tell me what these are? I just need a good starting point for researching.
  11. 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.
  12. 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.
  13. 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.
  14. Crabs - Worth prepping?

    While I was on the crab topic I also found three nodules that I popped but didn't want to take the chance prepping due to their size. Are these small crabs worth prepping in the condition they are in?
  15. 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!
  16. 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!
  17. 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.
  18. 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?
  19. 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?
  20. 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?

  22. 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.
  23. 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?
  24. 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.
  25. 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.
