  1. Fossil ID: Mahoning County Ohio

    Hello, I came across this while collecting some rocks to test. I did not take it for a fossil at first, but I am at a loss concerning what could have formed the pattern of the rock. The raised lines which I can only describe as “veiny” are really well defined and contoured. The dimensions are 4cm x 1.75cm x .75cm. I believe the rock is shale and it was found in Northern Mahoning County near Youngstown, Ohio alongside a river. The geologic map suggest that the rocks in the area may be from the Pennsylvanian period. Any help you guys can offer would be appreciated.
  2. Can anyone help identify this fossil
  3. New way to identify that coprolite as long as you can get some DNA out of it. Can tell difference between dog and human. https://phys.org/news/2020-04-feces-coproid-reliably-sources-ancient.html
  4. Cave find

    I located this item in a cave where other items where located too. It’s about 1 1/4” long by about 3/4” wide. I am new to this forum and would like any guidance you may offer. It has been enjoyable looking through the posts. Thank you.
  5. Fossil ID?

    Hi I found this thing that looks like a vertebrae. Was found on the beach. Is quite heavy.
  6. Fish Fossil (Knightia) Structure ID

    Can anyone identify these structures protruding from the top and bottom of the fish?
  7. Is this fossilized tree bark? Help please

    Need help identifying what I'm guessing is Fossilized tree bark I found On banks of Yellowstone River. Erosion this year is nuts. More just this spring than I've seen in 33 years of Spring flood erosion.
  8. Hello, I hardly know anything about fossil identification but was given these fossils a while back and thought I ought to know what they actually are. They look fairly common and from research, they look most like an ammonite and a fish fossil maybe but I'm not sure. Any help would be much appreciated and pictures of both fossils are attached. Thanks, Harry
  9. Is this a fossil bone?

    Hello I was wondering if anyone could identify this fragment, which I think might be a fragment of bone, but am unsure. I don't have a lot of knowledge when it comes to identifying Pleistocene fossils.
  10. Hello all, I have been a long time lurker and decided to finally have a voice. I am a long time rock lover, and unfortunately am in the beginning stages of trying to learn everything I forgot as a child, ie. I am happy to take constructive criticism. I have been traipsing through muddy creeks and cut roads looking for rocks that are interesting. I happened across the embedded rock a week ago and I don't know where to begin in the identification process. The picture attracted is on a slope that leads to a creek in Richland Hills, TX, just east of Fort Worth. I assume the city cemented rocks together to prevent erosion and they did a really great job. This fossil(?) is about 8 inches by 10 inches and appears to be a rib cage. Would anyone be able to help me in determining the proper steps to take to identify what type of animal this was?
  11. What could this be.

    While fossil hunting at the foothills of the Appalachian Mountains in North Carolina, I came across this critter. I don't think it's a Crinoid, as the little groves and very tiny, even compared to some small Crinoids that I found. I'm thinking of some sort of Centipede type creature, but have no Idea. Any thoughts or help would be greatly appreciated. I was tickled to find something a tiny bit different. Thanks in advance Joe
  12. Hello, My nephew has found what could be a fossil in a paving slab recently laid down at his house in Stratford-Upon-Avon in England. He wants to know if it is a fossil (and if so what kind of fossil it is) and I could do with some help identifying it. A picture is attached and I can attempt to get any extra information needed. Regards, Harry Keig
  13. I stumbled across an Atlas Obscura article about the American Museum of Natural History's annual Identification Day. The Fossil Forum's own @Carl was featured prominently in the piece! Check it out. It's a fun read! Daniel
  14. Is this fossilized coral?

    Hello! I am wondering if this might be coral? It was found in a creek in middle Tennessee.
  15. Hello! I'm wondering if any of these shells are known to ONLY be found in shallow water. If so, which one? And how shallow are we talking-- 10 meters? 100 meters? Found near the Azores, depth unknown. Some forams can be used for scale. Any help will be greatly appreciated. Thank you!
  16. Iowa Mammal Teeth ID

    Hello, I'm a new member to the Fossil Forum, could someone please help me ID these teeth? I found the larger, blacker tooth this morning on a sandbar of a creek in Linn County, Iowa. My wife found the smaller tooth on the same little sandbar about a year ago. I have found several bison teeth in the many other locations I have walked up and down this river, but these two have been stumping me. These are the only teeth we have found so far that still have roots intact which leads me to believe that they did not travel very far in the creek. These may or may not be from the same animal, but two strange teeth from the same spot makes me wonder if that could be the case. The smaller one has a stylid, but even the small one is thicker than the bison teeth that I have. Two photos compare size to a modern bison jaw. Small tooth: Width: 26mm Thickness at top: 16mm Enamel height: 32mm Large tooth: Width:29mm Thickness at top: 27mm Enamel height: 14mm
  17. Fossil Identification

    I regularly creek walk searching for arrowheads, fossils, and minerals. I have found a few teeth that I have no idea about and would appreciate anyone’s help in helping me towards an answer
  18. I found this rock over weekend and thought it looked strange. I think it looks like some kind of fossil, but I know nothing about identifying fossils. I would appreciate any help trying to identify what this is...thank you! I found this in Lincoln county Missouri, which is northeast Missouri. I have more pics on phone but was only able to upload these 3.
  19. As I understand, there are several practices when naming fossils. If I have a confirmed mosasaur tooth in which I know the definite species, I name it: Tylosaurus proriger If I have a mosasaur tooth in which I know the genus, and the species resembles T. proriger, but I am slightly unsure, I name it: Tylosaurus cf. proriger If I have a mosasaur tooth which looks just like T. proriger, but I know it's a different species for sure, I name it: Tylosaurus aff. proriger If I have a mosasaur tooth in which I know the genus but not the species, I label it: Tylosaurus sp. OR Tylosaurus indet. If I have a mosasaur tooth in which I cannot identify the genus, but it resembles the Tylosaurus family, I name it: cf. Tylosaurus sp. Did I get that correct? .sp = 'species' .cf = 'confer' meaning 'compare with' .aff = 'affinis' meaning 'it has affinities of that species' .indet = 'indeterminate' meaning 'there's no way to confirm this' Next up, what if I have a mosasaur tooth that is worn down, but comes from an area with high Tylosaurus density. I know it's probably Tylosaurus, but I can't be sure. Is there any way of labeling a fossil with the message: This is probably a Tylosaurus?
  20. Newbie fossil help

    Hi! I a am new to fossil hunting and would love to know more about these two that I picked up at Burling gap East Sussex. Many thanks x
  21. Went to Venice for a bit this afternoon assuming we won't have beach days with Irma headed our way. I had some nice finds and a beach almost all to my self. Two thing I'm unsure of, one I'm assuming is part of a turtle shell, the other I'm unsure of. Thanks for any help
  22. More fossils from Calvert Cliffs

    I would greatly appreciate help with identifying exactly what fossils I have here... Again, they were all picked up at Calvert Cliffs, MD. I am most interested in the odd little (tooth?) second down on the left. Thanks so much!!
  23. Fossil vs. geological

    Ok experts.... Severely eroded (dolphin?) inner ear or funky looking stone/pebble from Calvert Cliffs, MD? I have a lot to learn... Thanks!
  24. Vertebra identification

    Hello all, I am new to the forum and to fossil "hunting" in general. I was hoping one of you could please help me identify a nearly intact vertebra I found recently at Calvert Cliffs (MD). It measures approximately 4.5" superior-inferior, 5" transversely and 5" anterior-posterior. I have several more pictures but am having a difficult time "re-sizing" the photos (as a true amateur would)! If you need more info/pics, please let me know. Thanks in advance for the lesson!
  25. Need help with ID please

    Country of origin China Just under 7 inches by 4 inches for actual matrix Sold as a snake dated 100mya Just something doesn't look right to be a snake, no vestigial limbs, vertebrae not as defined as a snakes would be as well as the 2 antenna looking structures, but the head is too big for 100% ID. Any ideas would be greatly appreciated Thank you
