  1. I received this nice theropod tooth recently, however it was collected in the 1940s and there's no record as to where it was collected (other than it was likely somewhere in the USA, but Canada is a possibility too as the person who found it often collected in Northern Montana). It might be a long shot, but I was hoping someone on the forum might be able to help me pin down where it came from. I say this it's still embedded in a chunk of matrix which looks quite unique. The matrix is filled with shells, so I'm guessing it's a marine deposit. I acquired two teeth, both in this kind of matrix, so I'm also guessing that dinosaur fossils are common in this deposit despite the abundance of shells. Any help would be much appreciated as they're both awesome teeth and it'd be great to get a better idea of what they might be from, but that's obviously impossible without knowing where they were found!
  2. Shark tooth ID (Texas)

    This was found by myself in Ellis County, TX. I believe the formation was the Atco (or at least the Austin Chalk & Eagle Ford, if I’m not mistaken). The scale is in centimeters. I can post other images if needed; these were the two I just happen to have accessible at the moment. A couple of people who saw it in person said it was Squalicorax. I have some Squalicorax that have the well-known distinctive shape, but I also know that Squalis have teeth that don’t have that angled look. I’d never seen a non-angled Squali tooth before. However, when I posted it online in a Facebook group, an experienced shark tooth collector was absolutely adamant that this is Cretoxyrhina. So now I am unsure. I am more inclined to say it is Cretoxyrhina, but I am far less familiar with vertebrates than inverts. Thank you for any help!
  3. I have been trying to look for an onchopristus numidus tooth to complete a collection of mine and I am unsure if these are genuine as it is from a website I am unsure about.
  4. Teeth from Tenere / Niger

    I just bought a handful of teeht for some dollars found near Agadez. Would be nice to get some id`s if its possible.
  5. Tooth?

    I found this on the bank of a retention pond. I have found horse, deer and mammoth teeth in the same area. Not sure if this is a tooth or not.
  6. Tooth maybe?

    Hello, I have two items I will be attaching photos of, what I believe are teeth. ( uneducated Guess) It only let me upload 2 pictures. I’ll try to pu the others in the comments maybe?
  7. Hi all! Found these in the Kaw river in Kansas this weekend. I believe this is the cannon bone of an equine-very heavy and nice patina. The others, eh, don't know. I believe this is a tooth, but from what I don't know. I would have guessed deer tooth, but not with the ridges, and way too small......Most intriguing are these two objects, one of which is stone, with a hole all the way through. The other also has a hole all the way through (one end still packed with sand), but really don't know. Maybe an artifact as opposed to fossil? Any help appreciated!..... Bone
  8. Is this a tooth?

    Hi, I found this tooth on a beach in eastern Havana (Tarara), Cuba. I have no idea what animal could it be, can anyone please help me to identify it?
  9. Tooth?

    The other side
  10. Tooth?

    I'm trying to figure out what I have here, can anyone help?
  11. Plesiosaur tooth/teeth?

    This kind of tooth surface, with the ridges, isn’t that for the most part, not a common plesiosaur feature? This is from Lyme Regis....what would you all think?
  12. Shark tooth in TN?

    Hello all! I joined this forum today after finding the fossil shown in the photo. It jumped out at me while we were skipping rocks along the Harpeth River just SE of Franklin, TN. Is this a shark tooth or am I nuts? Whatever it is, it's clearly seen better days - so I understand if an ID is just not feasible. The shape seems right but the texture gives me pause. I've always been one to pick up cool rocks and fossils, but I know little-to-nothing about their actual names/classifications (yet).
  13. Removing hard rock matrix

    I have a theropod tooth that has hard rock matrix attached to base. What is the best technique to remove it safely? Thanks in advance.
  14. Fossilized tooth?

    I found this fossil while I was working a creek in SW Missouri. I first thought it was a shell, but after cleaning it up and examining it further, it’s looks more like a tooth. What do you guys think? If it matters, I found it near a Native American camp, not far from where I once found a Vero Tapir foot bone.
  15. Tooth or rock

    Found on the surface in Sacramento Co. CA.
  16. Saudi Shark Tooth

    Hi everyone. Recently I received from a familiar this shark tooth from Saudi Arabia. I'm trying identify the species. Maybe Striatolamia? From Umm Wu'al Formation (eocene I think) Allí the best JUAN
  17. Hi, I saw this tooth for sale and i am wondering if it looks like it could be a Ceratosaurus tooth. I read something about Ceratosaurus teeth having vertical ridges on the inner crown so i think it could possibly be a good match. It is .75 inches long and comes from the Morrison Formation in Wyoming. Thanks.
  18. I bought this one already, my very first fossil of any kind. Is there anything that sets off any alarms? I know people usually enquire about longer teeth which might show signs of extension, but I would feel better just making sure. I also have my eyes set on a batch of 5. From what little I've researched, those 5 set off more alarm bells but I'm at my max total for attachments.
  19. Found this odd fossil on Myrtle Beach 2-18-2020. Never found one like this. Personal opinion it resembles a crocodile tooth that broke, and point recessed into the larger portion. However it is very solid, and there seem to be no seams to confirm this (and it was a wild guess on my part anyway). Hopefully one of you has a more educated opinion. I'd love to hear from you if so. Thanks for looking and happy hunting.
  20. Hey everyone, I'm new to the site so hopefully I read all the posting rules correctly. Having said that, I was given this meg tooth as a gift. I am unsure however if it is real as it's missing the serrated edges and has a remarkable polish that gives it a glassy texture. I am not aware of any restoration methods or what not when it comes to selling to the general public so I can only go off my own knowledge of meg teeth. It's also heavier than my phone. Is there anyone who could maybe point out some red flags (or green ones!) to let me know if she was sold a replica? I can also add more images if need be. https://www.dropbox.com/sh/1bcvrtv7m6d7q13/AAD-RcmDpOCMgeJ6aJ_Xh40Pa?dl=0 Please click that link to view all 6 images. (For some reason I can't upload them here)
  21. Argentine tooth ID

    Hello Everyone, I have had this beautiful Argentine theropod tooth for 18 months now and the previous owner 25-30 years before the ban was introduced. The locality information is a bit flakey, however I thought it would be worth a try to get some kind of ID if possible if there are any Argentine friends out there with some information to hand. I have taken some measurements as follows: Distal - 12 per 5mm Mesial - 12 per 5mm MCL - 18mm MCW - 10mm crown height - 39mm If any further measurements are needed let me know Thanks!
  22. Tyrannosaur teeth decision

    Hi I have a question would a whole tooth be better then a whole bunch of pieces of a tooth? I found some Tyrannosaur teeth and there was a whole tooth for a more expensive price and there was a whole bunch of tooth pieces for a lot cheaper then the full tooth. Which would be better for research purposes? Thank you!!
