  1. I found this over 15 years ago in an alley. I have kept it in a box all this time and now would like to finally figure out what it could be . Any ideas ?
  2. New Jersey Cretaceous bone

    Greetings! I recently found this piece of fossil bone around the Big Brook area of Monmouth County, New Jersey. I believe it to be Cretaceous. A lot of bone in this area is scrappy and tough to identify but I'm hoping either the structure or features might be able to identify what this is from (or anything else about it). Thanks again! -Frank
  3. I accidentally broke part of this fossil when I dropped the rock it was in. It measures about 8 inches with a 2 inch diameter. No clue what it might have belonged to. This was also found on the Dry Frio River.
  4. Bone or Coral? *updated*

    Hi all, Fossils pictured below were found in the Chesapeake Bay. They all seem to have the same swirled pattern. Curious to know whether if it is actual bone or some sort of coral I am thinking. Edit: Added more pictures. Note the swirled 'lines' within each of the pieces. Hope this helps.
  5. Since getting into fossils something has been bugging me alot about material from the Jurassic and especially material from such places as colorado, utah, etc. Alot of bone material I see online for sale, mostly fragments in various sizes are usually unlabeled and generalized as being from any dinosaur from the Jurrasic. I wonder if there is at least a way to differentiate at least herbivore bone from theropod bone (like allosaurus from camarsaurus)? Is it similar to the method used for cretaceous bone of the honey comb pattern or not? I'm curious why it seems harder to identify Jurassic bone piece, I'd appreciate any input or discussion, thank you. For example would the first two pictures be considered theropod and the last herbivore?
  6. Kem kem fossil bones

    Ok so after doing a lot of buying collecting and digging in the Kem kem area of morocco I have some nice finds that I could use help identifying if that is ok first one to post is a vert unsure of its species though and ultimately did not buy as was expensive but would love to know the rest of the fossils I own need cleaning before taking pictures but when that is done will post here if that is ok with you good folks.
  7. Just rocks?

    My boyfriend just got back from hiking and came back with a backpack filled with rocks!? He thinks they are fossils. Can anyone help identify? Thank you!!!
  8. Fossil

    Hello, This fossil(?) was found in Lithuania. What could it be? Maybe a tooth? Thank you
  9. Unknown Small NJ Cretaceous Bone?

    I found this piece a long time ago in a cretaceous site in New Jersey and haven't really been able to figure out what this is since. I'm not sure if its fish, marine reptile, dinosaur, or etc. Just noticed it browsing through my collection and figured this would be the best place to get help, any help appreciated to get a label on this, thank you.
  10. Hi everyone! I haven't been here in a while! I finally went back down to the North Sulphur River yesterday and found this small piece of fossilize bone. Do any of you know, possibly, what type of feature this came from?
  11. Fossilized bone ID or speculation

    Found in my yard about 2 miles from the coast. I live in Charleston SC. https://www.flickr.com/photos/14372793@N02/albums/72157688823647345

  13. Could this be bone?

    I found this in the North Saskatchewan river in Alberta, could ths be a fossil? there is no coating on this it is just that smooth. it is 3" long and 2" at its widest point.
  14. Fossilized bone?

    I found this in Raubsville Pennsylvania
  15. Daughter's find

    My daughter found this back in June in the hell creek formation in Montana. I'm not sure what kind of bone or dinosaur it would have come from so she asked me to post it on here for the experts to advise. My best guess was part of a vertebrae but I'm not sure. Thanks in advance.
  16. Bone tool?

    I found this in a creek in Claiborne County, MS. It is bone and it is petrified. The smooth, straight sides are what is perplexing and even more so the "spiral on the one side. You can see the "spiral" in the photographs. This may be something comman and not man made. Can anyone help me with identifying this? Is it Native American? Photo of the "back"
  17. Allosaurus bone fragment?

    I purchased this bone fragment at a fossil show. It's from the Morrison formation of Utah. I suspect it's theropod, most likely Allosaurus because of its hollow nature but I just wanted to get other opinions on it. Thanks everyone!
  18. Hello - I'm hoping someone might have an idea what this is. We found it in the surf off the coast of North Carolina. Looks to me like it might be the socket of a ball and socket joint but other than that, I have no idea. It's hollow throughout. Any thoughts on what it might be?
  19. Inspiration and advice please

    Hi master prep guys This has been a real challenge for me and I'm struggling. Any wisdom much appreciated. Potentially I've got a lovely ichthyosaur paddle here but it's driving me crazy. The matrix is so flaky I've had to put a stack of thin Paraloid on to stop the matrix disintegrating. I'm wondering if adding the Paraloid has stuck the matrix to the bone. The matrix is softer than the bone but is dangerously flakey without the Paraloid. I have a pen, pin vice and a hammer. The last tool is rapidly becoming an option! Should I selectively remove Paraloid-ed matrix? Other thoughts?
  20. What did I just find?

    I was just on a trip with some friends near Ochoco National Forest in Oregon and stumbled upon this. I weighed myself with and without this thing in my hand with a digital scale accurate to .1 lbs several times and it comes in at .7 lbs. Thoughts? Thanks, y'all. Dillon
  21. professional fossil prep

    Hi - thank you to all that have helped me to acquire so much information on my fossils/concretions. How would I go about hiring a professional to prep some of my larger bone fossils? I assume it would be very expensive and would like to know if it's worth the time and money. I posted several photos in the ID section under the title "Bone or Concretion" and "is this a sea lion". If needed I can resend to this post. Thank you for your continued help and knowledge... very much appreciated!
  22. ID help please

    I have no idea. Found in North Charleston, SC in a recently dug pond. Any ideas?
  23. East Iowa Bone Fragment?

    This was found in stream bed near Mississippi in southern Iowa. Uncertain if this is a fossil bone fragment. It is very dense and about 5 cm in length. Any thought on how to ID this specimen/material?
  24. 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.
  25. Fossilized bone?

    Is this a fossilized bone? or just something else?
