  1. I found this in a playground in Dallas when I was 7. It was mixed in with the gravel, which was polished "river rock" that I imagine had probably been dug from a quarry and run through an industrial rock tumbler. As a result, I have absolutely no idea where it originated. It's about 15mm long, feels smooth, and definitely isn't serrated. I know an exact ID is pretty much impossible, but I'd like a general idea of what it might have come from, even if it's something as broad as "shark". It looks a bit like some of the teeth in a box of assorted fossil shark teeth (you know, the gift shop kind) that I have, so that's my current guess. I can try to find a better camera if better pics would be helpful.
  2. I thought I would post my collection of self found fossils. This will be a work in progress. I will start with some of my favorites. Here are my megs from Brownies Beach, Calvert Cliffs Maryland
  3. Hello: This was found on the beach in North Carolina. I can't remember if I was told if this was a small horse tooth or a bison tooth. Any help is always greatly appreciated. Thank you, David
  4. I found these at Aurora Phosphate mine. Are these sperm whale teeth? I remember as a kid I found these and all the adults on the bus (as everyone is showing off their finds) gave me ugly looks, hahaha. It was all in good fun, but at that time I knew I found something cool. Ahh the good ol days.......
  5. I recently aquired this at a local shop in China. I'm assuming it's real (as there are many fakes), because of the weight and feel and the crystalization, where the tooth is broken. I'm not sure how to begin the fossil identification process. If you have any tips about the process of elimination, please let me know, I'm very curious about the date period and of course ID'ing what they would have belonged to. Thanks for your support!
  6. Please help identify. The teeth shown in the pictures were recently found at the W.M. Browning Cretaceous Fossil Park in Frankstown, MS. Oddly enough, they were found within about 15 minutes of each other in the same area. Each tooth is about 1/2 inches from tip to base and they all have the middle indentation in the base. In the photo of four, the left most tooth has the lines running through it, while the middle two appear to be more smooth and without any features. The tooth shown on the right appear to be more of a rock until I noticed it had the same indention in the base. Any insight would be most appreciated. Thanks
  7. Didn't get out to the cliffs this weekend, so I decided to make a floating sifter. This one has 1/4 screen in it. I am going to make another one that has 1/8 screen, but I'll have a smaller 1/4 screen that fits over it along with a scoop that I can pour water over the larger screen. I think I will fashion some sort of strap on it so I can carry it on my back so that I can still surface collect until I get to a good sifting spot.
  8. This was found by my son today while we were fossil hunting at a local beach in Calvert County, MD along the Calvert Cliff formations. We are guessing a fossilized molar but not quite sure. Any help in identifying this piece is appreciated. Thanks.
  9. I was wondering if anyone could help me with these Meg teeth. The black one was sold to me as a juvenile tooth. My question is how can you tell if it's from a juvenile or if it's from a grown Meg but just located in the corner of the jaw where the teeth are smaller. Same question with the lighter colored one. That one was sold to me as just a Meg tooth but I was wondering if there is a way to tell if it's from a juvenile. Thanks for any help
  10. Hi, Can someone help identify this tooth? Is it just from a cow? It is from a creek in the St Louis, MO area. I've had it since I was a kid and have always wondered what it is. Appreciate the feedback!
  11. Hello. My girls and I found this tooth along the banks of the Cooper River in Charleston, SC, USA, while fossil hunting. I've seen pics of horse teeth, but this appears to be more flat than the squarer horse teeth I've seen. I found a few shots of llama or camel teeth online. You can see a bit of serration on the top of pic 3 which makes me think it definitely is a tooth, but a camel in SC?
  12. Mosasaurus jaw fragments

    Jaw fragments of a mosasaur.
  13. Is ceratosaurus dentisulcatus the biggest known of its species ? would its tooth be different from its other species tooth length,size and serrations ? is there any difference between magnicornis and nasicornis ?
  14. Found this in the TXI Cement Quarry in Midlothian, TX. It is 1.25 inches tall and about .5 inch at the base of the fossil. This is the ATCO contact between the Eagle Ford Shale and the Austin Chalk formations. Other finds in the area are Cretodus, Pytchodus, Squalicorax and other shark teeth, as well as fish verts. It has pyrite crystals up the middle of the fossil. Thanks for any help with ID
  15. I picked up this small but well preserved mako tooth from the auction site yesterday. It caught my eye because of the small cusp-like features and what appear to be (very) rudimentary serration like waves along the edge by the cusps. It is from Chile, so the location would be right for a transitional tooth. When it arrives I'll post some shots under the microscope. I'd like to hear others thoughts on this tooth. The truth is, for $15, I don't mind if it is a transitional tooth or not, but serrations had to start somewhere edit: I added some zoomed in photos from the original auction, this site seemed to have stripped some of the detail out after publishing.
  16. Hello everyone I am new to this forum but hear that you are excellent at helping with fossil id. These three fossils came from a recent trip to Brook bay on the Isle of Wight and I would really appreciate any input anyone can give me on them. The scale in the pictures is mm so both the tooth and rib are around 1cm long. The nearest match I can find for the tooth is a juvenile Baryonychid (based on Sweetman's paper). It is ridged down the edges rather than on the sides but it is not big enough to be Baryonix. There is one tiny rib(?) which I have no idea on and no idea whether there is anything on it that could support any identification? The last bone looks to me like it might be a limb bone from something about fox sized. Could that be right or am I miles off. I am really bad at ID so if anyone can set me straight on any errors above then it would be much appreciated.
  17. Hi folks! I'm just getting started on fossil collecting, and have bought a few small things at rock shops. Just bought something online, and I was hoping to confirm it is what I understand it to be. To my beginner eye, I think I have a pretty good sized Mosasaur tooth (not sure what type) in one of those composite matrix setups. I'm leaning towards it having been stained or painted a little too to bring out the tooth. Not sure on that point though. Just one small spot on the matrix in front of the tooth point that glows in black light. Everything else has no glow. Here are some photos. Paid about $50 for this, no clue if that's way too much or not. I liked the look of it, and even if composite matrix they did a really nice job making it attractive for a shelf IMO. Thanks for your thoughts everyone!
  18. I found this on a beach in south-east Norway. Someone told me that it is some kind of bone, but I don't know what. It kind of looks like a tooth? Anyone know what it is and how old? Thanks!
  19. Here's something I found in alluvium this fall. The location is Dorchester County, SC, Oligocene, almost certainly Ashley or Chandler Bridge formation. These formations are known for a variety of marine vertebrates including Elasmos and bony fish including Scombrids and billfish, marine turtles, cetaceans, sirenians, and crocodiles. Fresh water species are apparently rare. This is about 4.5 cm long, less than 1 cm diameter. It is not quite round in cross section, but has a slightly flattened side. I want it to be a Waipatiid dolphin "tusk". These are known from the area. It doesn't seem to have any enamel. Could I be right, or am I completely off base? Opinions appreciated. G
  20. I found this fossil I need to clean up a bit. It's 7cm long, smooth and more or less straight. I found it in Richmond, Australia. I think it's a Plesiosaur fossil but I am wondering if anyone has second opinions or can confirm!
  21. This tooth was found in South Dakota. I think I know what it is, but wanted some other opinions. Thank you
  22. Hey guys, I've been off the radar for awhile .. work you know .. been working on Siggraph for those of you who are familiar with software development. Just wanted to start a new topic here .. This one is right at 3.00" - 7.62cm C. carcharias Bahia Inglesa Formation South of Caldera Provincia Copiapo III Regio de Atacama Chile
  23. Found this in a river a few years ago, and liked to believe it is a tooth. However unsure of true identification, and its very possible its just a stone. The base however looks similar to how a tooth does below the gum line, with pronounced difference in textures, which has led meto belive it maybe more than a rock. Please help. I can supply better images if needed.
  24. I have some white shark tooth for trade! These are all from South Korea, and obviously real. I want unprepared things like crab, trilobite or mammalian fossils. (And I live in South Korea, then we have to use international shipping.)
  25. Hi all, I found this tooth in a locality where the formations of the Black Creek Group are present in Eastern North Carolina. The Black Creek Group contains the Tar Heel Formation, the Bladen Formation, and the Donoho Creek Formation. These formations are late Cretaceous and range from early Campanian to early Maastrichtian. Dinosaur fossils are known from this locality, including hadrosaurs, tyrannosaurs, and dromaeosaurs. This locality primarily preserves marine fossils, such as shark teeth and crocodile teeth and bones, but also dinosaur material. There are serrations on the tooth, however, I am not sure my camera can capture those. I believe that I need a different lens for that much magnification. Would love to hear thoughts about this tooth. I would be happy to provide any additional photos or information that may be missing. Thanks!
