  1. Fossil question

    I was wondering if anyone knew any good places to hunt fossils or rocks in Minnesota where I live or Wisconsin
  2. I found this fossil / mineral over at Folkestone, and would really appreciate any help in identifying it. It looks like it could be part of a larger organism, but also appears rather crystalline in shape. Does anyone have any ideas on this?
  3. Ancient alien bite mark!

    The bite mark(lol I know it’s not a bitemark) is an inch long and ONLY that part has crystalline chips in it. Any help would be appreciated.
  4. Fluorescent Bacculites.jpg

    From the album Fossil Flourescence

    I was playing around with the UV lamp in my lab, seeing what might unexpectedly glow this afternoon. This was a nice surprise. It's an internal mold of Bacculites sp. with sutures that fluoresce orange under 345nm UV light. Bright orange like this usually indicates calcite, a mineral that makes up fossil shells and some modern ones, too. Between the mud-filled chambers, the shell was preserved while the exterior of the cone wore away. The shell material was either calcite to begin with or, more likely, began as aragonite (same chemical compound as calcite, but different crystal structure and glows yellow instead of orange) and changed over millions of years to the more stable configuration of calcite. Meanwhile, the mud looks like it may have a little bit of some fluorescent minerals in the mix, but it's mostly a daylight-only affair. The blue may be some residual glue from a label. This specimen is from the late Cretceaous Pierre Shale Formation in South Dakota.

  5. Fossils, or...?

    I tough these two "things" were coprolites (cut and polished), but after taking a look at past discussions here I'm no longer sure. On other other hand, I don't know of minerals that would grow on a spiral. What do you think? Diameter is about 10cm and 5cm, respectively. No idea about provenance - both bought at flea markets in Germany. Thanks in advance
  6. I have been unsuccessful in getting information about this on the general internet (the All-Knowing Google failed me, AGAIN! ). How in the world can you tell if a rock that you have in hand is a stromatolite as opposed to just a rock with striations- like agate or something? Especially if the stromatolite has had a section cut and polished?
  7. Possible fossil find

    As a newbie first of all Hello everybody Today I was hiking and found an interesting rock along side the old mine road. Knowing that this type of rock may contain crystals I had it split open. It was quite a big rock, but the crystals were so tiny I could hardly see them...so anyway I was about to dispose of it when I noticed something unusual. To me it looks like a piece of a small perforated skin...but to be honest I have no clue what it might be... Any thoughts?
  8. Yearly Family Reunion

    We just arrived back from my wife's family reunion held in Kennett Square, Pennsylvania. In the past, during such trips, my goal has always been to check out a few fossil spots while visiting kinfolk. This trip was no exception. Unfortunately, the weather was trying to be uncooperative so we visited a few museums and arboretums during some of our down time. The Delaware Museum of Natural History was average at best but was air conditioned!!! Just the right size for children (see the T Rex pic) but not truly stimulating for adults. Longwood Garden was our next stop. It , on the other hand, was absolutely WONDERFUL!!!! Beautiful landscapes, festive fireworks alternated with fountain displays at night. A strong recommendation to visit if in the area. My favorite area was the water gardens and some lovely pics have been added to the forum's "Nature Photography" post. Take a look if interested. Here is @snolly50's favorite. One more floral picture that I liked. Next on the itinerary was Sunnybrook Creek. Due to the heat, I thought a wade in the water would be nice. However, upon arrival, I found the creek to be dry!!! So my desire to cool off was shot down. I did spend about 30 minutes in the creek bed before it became uncomfortable. The creek has many minerals in it but botryoidal goethite is the common thing found.
  9. Was this rock underwater ?

    In our cottage in an island there are these big rocks that were dug up from the ground when we first built our house but there is one rock in particular that looks like it may have been underwater at some point and I sure am interested in the possibility of maybe finding some fossils, what's your opinion ?does it look like it may have been underwater? And could this area have fossils? Thanks
  10. Visiting Devils Tower Area

    The grown-up family and I are heading out to Rapid City/ Belle Forche for some Hell Creek goodies and making a side trip to Devil's Tower. Going to be free July 7 and 8. Was even meeting if anyone wanted to meet up to hunt in the area or recommends a good spot. Happy to bring some east coast fossils with us.
  11. Fortress of Solitude

    Found this in a parking lot gravel bed. Thoughts?

  20. Fossilized bone or not?

    Hi all, Looking for some help to identify if this is a fossil or not. It was found in Freshwater East beach in Wales, UK (SA71) over the New Year. It's quite heavy (103g) and stood out as It didn't match any other of the red limestone or grey pebbles around it. Dimensions are 7.5cm long and 4.5cm wide. It is slighted flattened on its side so would measure 4cm. Thought it was a fossiled bone as the ends appear rounded and porous whilst the sides are smooth. Appreciate it might be fossiled wood or mineral too. Any ideas would be greatly welcomed. Many thanks S
  21. Please help identify geologic or biologic

    Hello everyone, Please help me identify if this is a possible plant or mineral. First time posting, thank you for your help.
  22. I finally completed the reorder of my collection of fossils and minerals. It is a wooden hexagonal display cabinet of several wood/glass shelf; in the pictures attached I only show some of them. I 3D printed more than 20 custom drawer compartments for the smallest specimens. I decided to go for a modular design, so I can adapt every compartment to the specimen. As printing material, I used a "wood PLA" filament 3D printed with 1 mm nozzle on the Alfawise U20 3D printer. I finally added a strip LED inside the cabinet door and powered it via a USB power-bank - so it is fully wireless. In this picture you can see some of my recent purchases: Two Sinosauridae indet. teeth from Kem Kem One Acheroraptor tooth from Hell Creek formation, Powder River Co., Montana Some Mosasaurus teeth from Kem Kem One Pterosaurs tooth from Kem Kem A piece of Rhinocerontidae indet. jaw from South Dakota Some ammonites, shark teeth, a Flexicalymene ouzregui, a couple of echinoids (I found the white one in a brick!); the Velociraptor skull is 3D printed as well. This is the other side. The big sand echinoid was also found by me in a brick! On the right there's a nice fossil coral: I never seen something similar, please let me know if you know it's name. Three fossil fishes and a nice ammonites cluster with some quartz in the background. At the end, some minerals... Now I only have to finish the cataloging of all specimen. I already finished with fossils, now I have to start with minerals - it will be very looong! What do you think? Do you like it? Ciao!
  23. Not sure? Fossilized Bone or Mineral?!

    I found this piece this past weekend. I’m not sure what it is..? Possibly fossilized bone but the consistency is so hard it looks more like a mineral to me? The middle is a beautiful tan, almost shiny metallic color at the right angle. Anyone know what it is?!
  24. Is anybody here going to the 48th Annual Gem, Mineral and Fossil Show in Westwego, LA (a suburb of New Orleans) on October 19- 21? I'm planning on going on Friday the 19th, and will bring my laptop so I can post photos to this forum for verification, since I KNOW I will get tempted by something!
