  1. Successful Experiment

    We have read many posts of members wanting to know the age of a bone found in a river because it looks really old, only to be shot down with the news that it is a modern bone. So I decided to conduct an experiment to see just how long it would take for a bone to take on an aged look enough to look like fossil bone. This past winter, we had some tremendous storms that our shores haven't experienced in a long time which deposited many things upon the beach including a bloated beached whale and many dead cattle along with their bones. As I was walking the beach I came across several cow bones and gathered a few. I took a nice white vertebra and wanted to do the experiment on it. All it took was a small plastic tub filled with water and a handful of dead leaves. The vert was placed in the tub, along with the leaves and water. It was then sealed with the lid, left sit for a month and shabam! An instant fossil. So the purpose of these little test was to prove that it doesn't take very long for tannic acid to do its thing and change the look of modern bone. Hope you enjoyed this project, I did. The last picture has another leg bone showing what the vertebra looked like originally.
  2. whale bone

    Heading back to Singapore with hundreds of tiny shark teeth for my fossil-less friends! I found some "whale bones" that someone had unearthed but left behind in the creek. A couple seemed unusual. One, while thick and heavily fossilized had a concave surface suggesting either hollow inside or maybe just a convex/concave bone piece? (Aquatic mammals don't have hollow bones, correct?) The second, also fairly thick and heavy but obvious fibrous "grain" on one side, has a straight v-shaped crease (about 1/8" deep) the length of the piece. Wondering if this is natural or possibly man made? There is also a much weathered piece which had some obvious fibrous grain when wet, not so obvious now. Looks like part of a joint?
  3. Another interesting GMR fossil

    Good morning everyone! I have another interesting fossil that I've been researching to identify and I'm stumped. My first thought was turtle but I can't seem to match the part to anything in the anatomy. I apologize for no scale in the photo but it's 2.5" long and just over 1" wide at its widest point. Thanks for the info!! In addition, this came directly from the green clay/quartz layer.
  4. Greens Mill Run, NC Fish Bone/Vert ID

    This was found a while back by a friend I was hunting with, busting open some rocks in the creek - nothing else was really in the rock but it was found with the usual GMR items washed into a gravel bed. There is a small vert attached to it but I am interested in possibly identifying WHAT bone that is attached to the vert and maybe even narrow it down to a type of fish (I assume it's fish). The bone attached reminds me of those tilly fish bones in texture/appearance. Any connection? 1- LOCATION Greenville, NC Greens mill Run. (Green Mill Run) 2- GEOLOGY/Formation Generally this location is part of the york town formation, Miocene-Pliocene-cretaceous 4- ASSEMBLAGE Shark teeth (mostly makkos, tiger near by) Belemnites and whale bone.
  5. Is it a hoof?

    Hi Everyone! I found this today digging in an outcropping of the San Mateo formation in Oceanside, California. I have found horse teeth at this site before. Not sure about this one, but I am wondering if it could be a hoof? Any thoughts are greatly appreciated! Thanks
  6. Bone shard or odd rock

    When I initially spotted this I thought it was a piece of fossilized wood. After looking closer I considered it might be a bone fragment. It's appears grainy and fibrous on one side and relatively smooth on the other. Or it could be just a chunk of rock.
  7. Large bone

    I know this is some kind of joint, but what joint or animal? Only thing I can think, large mammal, I have about 6 guesses.
  8. Good afternoon to all! Any idea what kind of bone it might be? Any possible animal for this bone? Thanks for all the help!
  9. Possible Bone Fragment

    Hi, looking to see if anyone can tell me if this is a bone fragment. I found this at a construction site near my home in Texas where dirt was recently dug up. It appears to have a fibrous structure and the ends are smooth and appear to have visible ends to fibers. Possibly a vertebrae fragment?
  10. Any ideas

  11. This was found in Mineral Wells fossil park in North Texas. It's a huge borrow pit that's easily 20 feet deep in some spaces, with everything gathered down at the bottom. Most of the things inside are crinoids and brachiopods, with the rare trilobite. I wouldn't expect to find a bone from anything in there, but this really looks like something to me. It's about 4cm long, and it feels like a pretty standard rock. The reddish-brown areas are smoother and slightly concave, and it looks to me like this was broken off of something. There's also an area on the back side where the same reddish-brown color is showing through just slightly, in a small ring about 1cm across that more or less lines up with the center space on the other side. I'd try to clear off some of what looks like matrix, but it's very hard, and I don't have the tools to deal with it. Any ideas?
  12. Hi. Im hoping someone could identify this specimen. It's very small, a little less than an inch long. I thought it was bone fragment at first but it also resembles some claw characteristics.
  13. An unknown bone

    Last Saturday I found an interesting looking bone in the quarry Kromer near Holzmaden (Lower Jurassic). Its about 4 cm long and extremely thin. Because of that I would say that I have found a bone of a pterosaur. But that would be a rare find at a place where you can find mainly marine fossils. (A friend of mine found some bones and even two pterosaur teeth "recently"). So can somebody confirm that idea or have another idea? Thanks for your help Here it is:
  14. Rib bone? Iron fence?

    The metal detector found this piece, there is more that we couldn't get dislodged from a root running through the ground where we were prompted to dig. We thought it was likely part of an old iron fence or wheel, but after washing the dirt off we aren't so sure. It's got a little weight to it, but seems like it might be part of a rib cage, from what creature in what era we haven't a clue. We were, as usual, digging by the creek under the bridge at the foot of the cliffs in Carversville, Pa, with a metal detector that we were using for the first time. Between our proximity to the bridge and it being our first time out with the detector, I'm not confident that it was these pieces setting off the machine. We are going back to dig up the rest of the pieces in the morning so will post more pics tomorrow if needed for further clarity.
  15. I found this nice chunk of mosasaur (?) bone over the weekend at the North Sulphur River in Ladonia, Texas. It has beautiful black enamel on each side that is very smooth and shiny. It has a bowl shaped curve to it on one side. I was thinking it was a rib chunk, but I wasn’t sure with it having the curve. What do you all think? Thank you in advance!
  16. Fossil scute?

    Hi all! Its been a while.... I'm thinking this is a scute of some kind but heck if I know what from. I've looked through the dozen + reference books I have and looked online for all the animals that might be from this location that may have a dermal scute. It does have bore holes that are not part of the original fossil. It is 2"x2.5"x0.75". I found it at Green Mill Run in NC yesterday. Thanks in advance ~ Joyce
  17. Bones, fossils, or just rocks...?

    Hi, I was walking along the shoreline north of Robin Hood's Bay earlier today (East Yorkshire, UK). I'm no expert fossil hunter by any means, but in a short period of time I managed to find a few fossilised Ammonites and various other sea critters. The area where I was walking is quite famous for its large deposits of fossils. Robin Hood's Bay is a tiny town with only 5 shops, 2 of them are fossil 'museums' with quite impressive items on display that have been found in the area. I'm aware that none of this information changes whether what I found was bone... or just a large rock... but it did make me wonder.... In the attached photos you can see the items which I discovered. They were initially covered by the local black clay/mud, which came away after quite a bit of hammering with a large rock (again, I'm no expert fossil hunter!). They were directly beneath a large rocky outcrop, at the right level/strata which local guide books indicate fossils are most likely to be found. Based on these pictures, can anyone tell me if these are bones/fossils? I'm more than happy to donate these to the local museum if they are genuine specimens. The location I found the items, the way the edges are curved and fit into each other and the fact they were found in the same kind of clay/mud that other fossils are found in lead me to question whether this was something a bit special... Thanks, Mark
  18. Kem Kem bone ID

    I know I should recognise this bone. I'm sure I've seen one just like it before, perhaps on this very forum, but an image search drew a blank. It's very distinctive. It has a completely flat, lobe shaped surface that it stands up on perfectly. 4.5cm long. Any pointers would be appreciated. Standing upon the flat surface: Flat surface sloping on the left:
  19. Ear bone?

    Hope these pics came out OK. I think this may be the inner ear bone (bulea?) of a whale? Found in the peace river, I don't think the dime made it in the pic. It is very dense and fills the palm of the hand, I bet it weighs, 3 ounces.
  20. Hello. Could someone please help me with a guess? What bone is this? And the probable animal that may have belonged? All opinions are welcome! Thank you!
  21. Kem Kem Bone Spike/Horn?

    I recently bought a whole bunch of chunkosaur pieces. Most unidentifiable. But there was some interesting stuff in there as well. This piece in particular looks interesting. At first glance it looks like just a chunk of bone. But then I noticed that most sides still show the outside cortical bone without much damage. The two main sides which are both subtly rounded, are vertically straight and seem to converge into a point. The whole thing is roughly cone shaped. Viewing it from the pointed end it is roughly oval shaped. There is a flat bit on the "underside" of the cone. The bone structure is very dense on one side and very rugose and open near the tip and the other side of the bone, indicating possible fast growth or remodeling. The broken inside also shows a lot of open spaces and air pockets. Now the problem is, that this looks to me like some kind of spike or horn. But I don't know of anything in the Kem Kem beds that has these kinds of structures. Crocodiles have scutes and such, but this piece doesn't resemble armour as it doesn't seem dense enough. Ankylosaurs have spikes, but those aren't present in Kem Kem and their armour is denser as well. The closest thing I could find with a similar shape, was the brow horn of Carnotaurus, which is also not present in Kem Kem. It's a really weird shape that I can't seem to place. Any ideas? Side and "top" rounded surface with dense bone. Other side view and the other rounded side. Cross section of dense bone. "bottom". And broken tip of the "spike". Details.
  22. Fossil bone, wood, or other?

    I briefly explored an old creek outside of Dallas, TX yesterday; a creek I used to explore as a kid. I didn't find much at all because it was so overgrown and difficult to access these days. I found a few pretty river rocks, a nice little shell fossil and what appears to be either a little piece of petrified wood or bone. I took macro photos of it tonight. Please let me know what you think. I'm baffled. Larger fossil bone pieces, with this color/texture, have been found in this creek many years ago.
  23. Isle of Wight finds

    Hi, After deciding to post an October find item, I thought I would post these photos for your suggestions. I prepped them all last weekend at the same time as the spine. Photos 1 -3 only had its edge showing and the matrix is really hard so the engraver came out, yeah it still works. Held my breath and went for it and managed not to break what I think is some turtle shell, it is 4cm long and 4mm thick. I am reluctant to prep the other side and remove all of the matrix as I do not want to ruin it completely. It is not much to look at but for the size of the fragment. The photos are self explanatory. The following ones are from the same rock at the other end. A chunk of bone, maybe part of a jaw it is 3.5 cm long. It was not until I prepped it that the tiny jaw 1cm long with 6 teeth sockets appeared to one side, one socket has a broken tooth in it, not my fault. Initially I only saw the end, I thought turtle shell as the profile was V shaped suggesting an edge. I dare not try to uncover it anymore It could be a small croc or maybe Amia which is known from the same matrix which is part of the Atherfield Clay formation, I really have no idea. Any experts out there please jump in with what you think it is. Cannot post it in finds as I cannot ID it, sugar.
  24. Brazos River, Texas - Sloth Bone

    This bone was dug out of the sand high bank on the Brazos river after Hurricane Harvey. There are other bones. But the sand bank is still to unstable to dig out the other bones until next summer. It weighs 7 lbs - 3ozs Anyone know what it belonged to? Thanks...... .
  25. Brazos River, Texas - Unknown fossil

    I found this fossil on the Brazos River after hurricane Harvey waters receded. I've found a lot of turtle shell, armadillo and glyptodont scutes over the years. But I've never found anything like this before. It is 2-3/4" L × 3" W × 3/4" thick and weighs 6ozs. Anyone know what this is? Thanks......
