  1. Hello all. 👋 Looking for some advice. I have some hell creek fm dino bone I would like to clean up but it has spots of lichen and iron. I tested some hydrogen peroxide in a small area and it seemed to clean up the iron. My question is if it will react with the "bone" material. Maybe soak it in HP or even Iron Out? Been a while since I took chemistry so I'm not sure about the interactions. Also, what is the best way remove lichen? Thank you in advance.
  2. Can the lights in the display cabinet damage fossil teeth or dinosaur bones?
  3. Happy Saturday, all! I'm helping a woman to photograph her brother's fossil collection. Everything was collected prior to 1967, after which he left the country. He's still living, but not easy to get a hold of. All of these items have been sitting in storage since then. I understand most of these may not be able to be identified. It's well outside of my wheelhouse, and I imagine many on here may be more familiar with material form the Morrison Formation. I'm going to add one or two per post to make it easy to differentiate. I'm most curious about the first piece which appears to be section of a jaw. If any additional photos are needed, please let me know. Thank you in advance! Label on storage boxes Some labels were included, but they were all jumbled. Fragments from the envelope.
  4. Hello! I bought this bone from England a long time ago and unfortunately I still don't know what it is. Unfortunately, I didn't note the exact location at the time and unfortunately I can't remember it either. All I knew was that the bone came from the Hastings Beds. Unfortunately I don't have any other information. The bone measures approx. 16 x 8 x 6 cm (6,3 x 3,2 x 2,4 "). I would be very happy if someone could help me and know which animal the bone belongs to. Unfortunately, I don't know anything about the ID of fossil bones at all. Perhaps the bone can be assigned to at least one group of animals. I would be grateful for any help! Thank you in advance from Germany!
  5. Came from a box of Lance Creek Formation Triceratops bones. Any idea what it is? Im guessing it’s a skull fragment but not sure.

    Is this a fossil?

    I made a post a while back about rocks I found in a part of Utahs poison strip known for having a lot of dino material. Based on the replies I decided everything I found is just rocks but with this one I am a little less sure because the texture is different. Some of it seems to be porous but there are are also parts that are a bit more smooth. I found it in a wash and wonder if running water could be a reason for this.
  7. Jurassic J

    I need help with identification

    Unfortunately the only information on the fossil is that it is from North America. I was thinking it is a distal femur or proximal tibia but really have no clue. Is it possible to ID the type of dinosaur with just the end of a long bone? Any input would be greatly appreciated.
  8. Fossil Collect

    Suuwassea vertebrae?

    Hi I’m wondering what this vertebrae is from. Seller says it’s Suuwassea but it’s always good to be sceptical. The bone is from Johnson county Wyoming. Not sure on the dimensions yet.
  9. Hey all! When I went on a collecting trip in the Hell Creek Formation in Montana, there were many iron concretions, and I've noticed that some specimens from there appear to be iron-stained. This makes me wonder if pyrite could be among the minerals involved in fossil preservation there. Are some of the bones found in the Hell Creek pyritized, and how could those be distinguished from others preserved differently? If so, do those Hell Creek specimens ever develop "pyrite disease," and what would be the warning signs to look out for? Thanks so much for sharing your knowledge!

    North Sulphur River Vertebra?

    Looks like a vertebra to me. Anyone know what kind?

    Dinosaur toe bone ID needed! JRF find

    Pls help with an ID of this toe bone found in Hill Cnty, MT. I have taken several views of it and it is 2.25" long. It had been exposed for a long time and had a layer of lichens on it. Is it Tyrannosaur related, raptor, or ?? Thanks!

    Possible Tyrannosaurid Bone

    I have this piece of chunkosaur from the Lance Formation. It looks like it might have the trabecular structure of tyrannosaur bone. It's from the Lance formation of Weston County, WY. Thanks for any help.

    Fossil Bone ID needed - Judith River Fmtn

    Hello, here is a bone I found in the JRF about a week ago. It was found in a site with various dinosaur and crocodilian teeth. Thanks for any help. It is 3.875" long.
  14. Hello, I made this find in the Alberta badlands yesterday, the area is known to have tons of hadrosaur bones, so i assume thats what i have. unfortunately, i was not prepared to extract the bone without completely destroying it, so i plan on going back to get it some time this week. I collected many bone fragments from the area, and have noted down the location. I will post decent pictures once and if i am able to bring the fossil home, i seem to have forgotten to take proper pictures in my excitement! I would also like to ask for advice on how to extract this fossil. I plan on purchasing some wedges to split the rock, to make it a more manageable size. beyond this, i understand that it is a good idea to stabilize the fossil somehow before extraction, what would you recommend i use for this? i would imaging an adhesive that is able to seep into all the pours, but i am not sure what i should use specifically. The second image is showing the rest of the fossil, mostly buried under clay. Thanks for the help!

    Hadrasaur jawbone section??

    Hello, I found this yesterday. I believe it is part of a Hadrasaur jaw. Please let me know if my thoughts are correct! Or not! Thx for any help.
  16. Hello, I believe this bone shows evidence of teeth scoring from a predator Dinosaur (raptor or other theropod) and I am asking for a confirmation of this. I found this a few days ago in Wyoming in a formation I believe may be the Lance but I am not sure. Teeth there include Archeroraptor, other Dromeausaurid (sp), triceratops, avaceratops, paralbula, myledaphus, hybodus shark, edmontosaurus, borealasucbus, brachychampsus, fish, a couple of mammal types, large theropods, Aublysodon?, lissodon, Ankylosaurid, melvius as the most commonly found specimens. Of course, none are common but just in comparison to other fossils.
  17. There are so many beautifully colored dinosaur bones. Are the different species the reason for the different colors?

    Is this a dinosaur bone?

    Hi peeps, I just found this at Yaverland Beach, Isle Of Wight, United Kingdom. Wondering if it’s a dinosaur bone?
  19. Recently I was talking to a friend of mine and I was advised that her granddaughter, who I had given some fossils about 6 years ago, when she was 10, was not into them any more. I advised her that if she did not want them, I would take them back. So today we met for dinner and I brought the fossils back home. Here most of the stuff- Eurypterid pieces, I believe from New York. Fish from the Brazil Santana Formation. Cephalopod pieces- Ammonite from South Dakota A clam from South Dakota- A couple Texas echinoids. Gryphaea from Texas Pinna from Texas Misc, Brachiopods Mazon Creek Annularia, Pecopteris and Essexella asherae jellyfish. South Dakota Oligocene fossils- coprolite and 2 large Titanothere bone pieces. Fossil shells from Florida- Dinosaur eggshell pieces from China. Starfish- Solnhofen, Germany Dominican Amber with insect inclusion Dinosaur bone pieces This cards were mine when I was a kid- printed in 1962. Petrified wood- Hirn coral- Southern Indiana Some modern shells- And a couple fossil books.
  20. A couple larger dino vertebrae I found on the Judith River last year, I believe the larger round one is Hadrosaur but not certain, the longer rectangular shape vertebra I have no idea. I was hoping someone would be able to help identify.
  21. These are a couple smaller vertebrae and a bone I found on the Judith River Formation, I was hoping to get an opinion on what dinosaur they would be from. Thanks.

    Need help to possibly ID item

    I found this bone fragment in East Feliciana Louisiana. It is translucent and looks to be crystalized. Bone width is 1.5 inches (round). Any help would be great and helpful. Thanks

    Bite Marks?

    I'd found this dinosaur bone on an online website and it looks like it might have bite marks. It's from the Hell Creek Formation of Harding Co. South Dakota. Here are the pictures.

    Dinosaur bone structure

    From the album: Dinosaurs

    This is a textbook example of dinosaur bone. Numerous Haversian systems/osteons are visible (which are the circular structures you see). They are actually cylindrical, but we are seeing a cross section here. Osteons are present in all cortical bone, but they are particularly impressive in dinosaurs. https://en.wikipedia.org/wiki/Haversian_canal
