  1. Found in Wisconsin - Help ID?

    I found this in our yard years ago while digging for landscaping. Does anyone know what this might be?
  2. New member;ID Request

    Hello new member here, my name is Robert! I found this site while searching google in an attempt to identify some beautiful items I came across recently while at the beach in san francisco. I understand most of you guys refer to yourself as amateurs, though reading a few forum topics before creating my account I was impressed with the amount of detailed information in regards to your studies and findings. That being said I must admit I am %110 amateur in my knowledge of fossils, different time periods, etc. So please forgive me if I seem to ask simple questions like I don't know what I am talking about, I am still learning. WELL, in regards to the piece I am hoping to learn about (please see attached image). I recently found it while I was at the beach in San Francisco area. It measures 2 and 3/4 inches wide, 2 inches tall, with a shallow depth of a 1/4 inch. My main question is...WHAT is it!? I've seen many sand dollar fossils, coral rock fossils, clam fossils recently on the beaches here, but I've only seen one like this. The milky white crescent shaped object that is offset to the right of the center of the stone, looks like a tiny shrimp or something (again , please forgive my lack of knowledge). Also, the only thing I can relate the slightly irridecesent dark blue-ish streaks to are the inside of some of the mussel shells that I see on the beaches here, so maybe it is in relation to that...? Again, I have no idea but I do speculate much as I've recently grew heavy in interest on the subject and those alike. It would be greatly appreciated if anyone has some pointers on or can possibly identify this, what I believe to be, fossil stone of some sort. I have many photos of all the beautiful items I've recently collected, and needless to say, so many questions I wish to ask you all in regards to them. I am planning to post detailed images of them all in the My collections section but for some reason most of my pictures on my phone exceed the "Max total size of 3.95MB" in the image upload section so I am going to try and take some different pics that are "uploadable". I would be more than happy to take new pics or zoom in closer on any specific area(s), if needed or necessary. Thank you all for your time
  3. Please help with ID

    I found this while rock hunting in the Stanislaus river, Modesto, CA. If anyone can help identify it I would be very grateful. Thank you.

  5. Florida Fossil or poop?

    I just got back from Satellite Beach, Florida and picked up something that looked like a coprolite. There were many of them and I grabbed the smallest one. How do I know what it is?
  6. Tooth?

    The other side
  7. Tooth?

    I'm trying to figure out what I have here, can anyone help?
  8. Is this a egg?

    Hi there, so I came across this rock awhile ago. I found it in the mountains just west of fort Collins, co. I've spent a lot of time trying to find information on it but not having much luck. It's pretty hard, doesn't leave a streak and has weird layers. It's around 2 inches or so and round-ish. Hope the pictures are good enough. If not, I can always take more. Thank you for any info!
  9. Found this formation on the bank of the Dnieper River, Ukraine, Kherson region. Sizes: 73mm length and 32mm width. Composition: the surface layer consists of steatite; the next layer is similar in color to the bone, has many small (less sand) and a little medium-sized pores, a hardness of about 4,5-5, actively foams under the action of hydrochloric acid; the inner layer of blue material has a dense structure similar to flint or chalcedony with impurities, chalcedony does not scratch. Can it be hidrotermal metamorphic fossil, or simply geology formation?
  10. Unusual patterned rock. Fossil?

    Hi All, My instinct says this one’s a dud. But it was just too unusual not to investigate. Any leads or answers are appreciated, as always. -size is approx 15x20cm -found on the beach -Haida Gwaii (near Alaska) Thank you!
  11. 3 more specimens - bones or rock?

    Checking on three more specimens found on Myrtle Beach - I labeled them 4/5/6. I'm very curious about #6. The more I look at it, the more it doesn't look like a bone.
  12. 3 specimens: Bone or rock?

    Found on Myrtle Beach. A recent post about a possible bone more likely being molten lava has me wondering about the other "bone" specimens I picked up. Here's the first batch.... Could you weigh in? Photos with and without flash if it helps.
  13. Please Explain This

    Hi all I just joined up today. I found something that I can not work out. I was walking along a dry creek bed in central Queensland Aus and found what looks like a piece of petrified wood encased in rock. How did this happen? Why didn't it burn up? Any ideas?
  14. Is this rock or petrified wood?

    This looks like petrified wood to me but I've had no success looking online to see how to determine if my hunch is real or not. I'd appreciate any help or suggestions about whether or not this is petrified wood. (Item is wet in the pictures) Thanks!
  15. Fossil or Rock

    Hope I am getting better at posting what I need ID for. Is this a fossil or a rock that just looks like a claw? Most all my rocks came from Mississippi while in MS Gem & Mineral Club hunting in and around Central MS. Some are from the Big Black river beach area, some are from other areas but sorry I can not tell you exactly, been way too many years.
  16. Two tiny rocks

    In my continuing adventure in our yard, I decided to scoop up a few tiny rocks today and examine them. This one was not much of a surprise. Am I correct in stating that it is a tiny bit of fenestella bryozoan? (measurements are in mm). Found in Huntsville, AL - I have found lots of fossiliferous limestone in our yard to date. It's the next one that puzzles me most... Thanks!| Ramona
  17. bone rock

    Slightly larger than a softball found st.marys ontario in backyard when digging
  18. Wondering what this fossil is?

    Wondering what this fossil could be? Looks like a plant fragment but not sure. Found on top of mountain in Wyoming. Thanks
  19. What are these fossils?

    Hi! I’m wondering what these fragments could be? Found on top of mountain in Wyoming. I found rocks with these that have snails but not sure what these are. Thanks!
  20. Is this just a rock?

    This has been on our bathroom window ledge for some time now. Iam curious to know if this is just a rock or something else. This piece has some odd characteristics such as; linear ridges, pores, indent around one edge that looks like something could have been attached, and a think dark center. I read if you lick a fossil It will slightly stick which it did. We live in North Dakota north of the Missouri river. I like searching for odd or unique rocks along the shore. I can't recall exactly were it was found but can say either from the lake or my yard which is a new development on farm land. I am not a master photographer but hope the images do it justice. Thanks for viewing.
  21. rock pick

    I have had this Pry-Axe brand made in Chicago for a few years. It is listed as a Fireman's tool. The only online photo I found has a different handle. So I assume it will be a good rock pick and maybe I can wrap like golf club tape on it? A SOG folding shovel with belt pouch. Has proven well made and handy. The maker of Multi-Tools.
  22. Fossil or just lines on rock?

    Fossil or just lines on rock?
  23. Ways to cut through solid rock?

    I found a nice well-preserved ammonite specimen while on a trip, the only problem is it’s in the middle of massive slab of stone! How do I remove it without utterly destroying it? Is it even worth it to try? Jackhammers are not an option. Is it possible to dissolve the rock using an extremely strong acid?
  24. Hello, I am new to this group. I found this rock while hiking in central Greece. It kind of looks like a paw inbedded in a rock. I picked it up because it's colour was unusual. Could it be a fossil? I have no idea what it is?
  25. Tasmanian fossil?

    Hi all, my son found the rocks below on a school trip in Tasmania and was very excited to have found dinosaur fossils wanted to ask if these are actually fossils or some type of rock formation or something else? Thanks.
