  1. Worm Creature from Arizona Desert

    Hello, I have been finding all sorts of neat rocks and marine fossils in the desert outside of Yuma, Arizona where the Colorado river had once flowed into a large ocean. There seems to be some sort of worm creature fossilized in this stone? I would appreciate an ID on the specimen, or speculation as to what it is? Thank you.
  2. Center cow Calvert cliffs

    Hi Randy here. A friend of mine found this tooth today along Calvert cliffs.its a center cow but is it pathological?
  3. Dino poop or just a rock?

    I was wondering if this could possibly be a coprolite? Or just a rock that has formed this way over time. Found in the Rocky Mountains of Wyoming. Thanks for your input!
  4. Archaeolamna kopingensis

    From the album Cenomanian Shark Teeth and other Marine Fauna, Ryazan Oblast, Russia

    Archaeolamna kopingensis (Siverson 1992). Slant length indicated by longest side.
  5. Cretaceous fish tooth?

    Hi everybody Recently I was examinating limestones with gastropods (turritelids) and I found this. I think it's a fish tooth, but I'm not sure. What do you think? From lower cretaceous (Lower-Upper Aptiense ) Sea sediments. P.s. Sorry about the quality. It's really tiny. P.s.2. How are you all? I hope everything is okay with this quarantine.
  6. Hi, please stare at this trilobite that I just snagged and tell me if you would agree with me that it's real, or if you think it's fake. If the latter, I would appreciate your reasons. Edit: pictures posted properly. Also I ask because I'm still very new at collecting.
  7. 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).
  8. Northwestern PA unknown rock or fossil

  10. Help me with Cretaceous fishes

    Hi everyone, i'm doing the thesis of master degree in paleontology and I'm studying a new internal lagoon near a carbonate platform. At this moment I can't go to university because we are in quarantine and therefore I can't consult with the professors and can't use various methods. So I ask you for help. Can anyone identify these fish, even just the family they belong to? They are all from the Turonian and they come from a kind of Plattenkalk and represent the only vertebrates found. Thank you
  11. Possible egg

  12. Hello! I’m not sure if this is going to be a “oh he had that set” type of post but I hope not haha! long story short about 14 years ago (when I was 12) I got a rock collection from a yard sale with my mother and inside were some cool fossils which I added rocks next to throughout. I forgot I had this for about 12 years. Each fossil has an identifying yellow card - I think I found the distributor of this from way back when but I’m unsure. I don’t want to sell anything as I kind of treasure my childhood but I’d love to know if this stuff is actually real because that would be pretty awesome lol! Apparently I have a dinosaur bone? I’d like to know! thank you for taking the time to look I also understand it’s impossible to verify without tests and stuff but, I’m hoping for some optimistic responses!
  13. An article that talks about fossil remains dated 47mya in the former coalfield of Geiseltal in Saxony-Anhalt about how ancient horses shrank and how ancient tapirs showed the opposite in that they got bigger. https://www.technologynetworks.com/tn/news/exceptional-fossils-give-window-into-mammalian-evolution-332518 Ring et al. (2020) Divergent mammalian body size in a stable Eocene greenhouse climate. Scientific Reports. DOI: https://doi.org/10.1038/s41598-020-60379-7 (the article is open access)
  14. Scallop i.d.? Unidentified fossil

    Good morning! I was hiking along a park path when I inspected a large boulder and found these two fossils, the first of which is similar to modern day scallop. I didn't have anything to measure with -my apologies, but it was approximately 1 1/4" in height and 1" across. the other object has some faint lines/rays emanating from ~9:00 to 2:00, but not sure it is overlying the underside of another shell, or is part of the fossil. This one is approximately 1 1/2" x 3/4 " Any thoughts and suggestions on i.d.s welcome and encouraged!..... not sure I could remove the scallop intact but thoughts on how to do that as well? Bone

  16. Hi there i continue to maintain my very very amateur status but I've been trying to read the different threads on here regarding spinosaurus jaw and what I gathered so far is pitting is reflective of croc jaw and if it only has a single socket or also makes it difficult to determine if its spino or croc. I found this one on our favorite auction site and wanted to get your opinion
  17. Please help with ID

  18. Hi all, we found way we hope is a fossil today in Lyme Regis. Does anyone know what we have found, if and how we can remove the outer layer to reveal what is hopefully a lovely fossil inside. best wishes Tim
  19. Howdy! I've been trying to properly ID some of my toothy finds from the Peace River and Venice Florida. Please let me know if I have misidentified any. Also, including a few that I am not sure about. Any help is appreciated! Pretty sure the are Megalodon, but not 100 percent. 1. 2 inches top to bottom 2 One inch top to bottom . 3 One inch, obviously. . Snaggletooth Hemipristis: 4. One Inch 5. One inch 6 Just over one inch obviously , Carcharinus (Bull Sharks? Whaler Sharks? Dusky Sharks?) Not sure what species.. Would like to narrow it down, but not sure about that. 7. 3/4 Inch 8. 9. One Inch 10 11. 3/4 inch . Lemon Shark - I am pretty positive on the Lemon ID I just wanted to show this precious teeny tiny tooth: It think that is a salt crystal growing on the side! 12. Tiger Shark 13 3/4 Inch 14 3/4 inch Unknown: 15. A worn Carcharinus? 16. 1/4 inch
