  1. I need help to identify these fossils

    Okay, so I have a couple of fossils in my collection, in which I'd like some more opinions on. First, I bought this un-identified dinosaur chevron bone. It is from the Kem Kem beds, Morocco.
  2. Theropod claw ?

    Would this be a theropod claw?
  3. Hi guys, I was wondering is this Spinosaurid with a root real? Seller state it has some restoration. I am curious about your opinions!
  4. Dinosaur rib bone?

    These two pieces of bone like things are from Henan. Are they rib bone fossil?
  5. Hey, everyone! I'm looking to trade for some shark teeth, preferably odd/obscure/rare teeth, but I'm open to any interesting species. I'm offering to trade this Kem Kem Carcharodontosaurus tooth, but am willing to also trade some other shark teeth as well.
  6. Kem Kem Theropod Tooth ID

    Hi Everyone, I wondered if I could get a second opinion on this tooth I got hold of a few years ago from the Kem Kem beds. It was advertised as a 1.7" Carcharodontosaurus saharicus but it looks nothing like most of my other Carcharodontosaurus teeth. I've attached below some photos. It's very narrow both laterally as well as across it's width. The carinae are both central and straight with no real twist. The mesial count is 18/5mm and the distal is 13/5mm along the midline. I've sadly no more details on location apart from Kem Kem. Any help would be greatly appreciated but I recognise that isolated teeth from Kem Kem can be problematic. Thanks. Tom
  7. Rolled Dinosaur Bone (found 2017)

    From the album Fossils From Compton Bay to Grange Chine, Isle of Wight

    Collected between Grange Chine and Chilton Chine on the Isle of Wight, UK. Wessex Formation. About 125-130 Ma.

    Just looking for little help identifying these small digits from Hell Creek. I'm guessing the bottom two are likely dinosaur or reptile, but I'm unsure about the top one. Thanks in advance!

  11. Fossil tooth?

    Hi everyone, could anyone help me to identify this fossil please. We purchased it in the shop but the seller couldn't tell us whos tooth is it.
  12. What is this tooth?

    This reptile tooth was in Heinz Walter Kozur's collection. But we don't know where he was collect it. Can anybody identitify what species (or genus) had this tooth? Whe think that is a Theropod maxillar tooth, because the tooth enamel is very thin, and trailing edge serration on it. You can find more pictures on these links: https://ibb.co/f9gNrV https://ibb.co/i5ODyA https://ibb.co/h5C6JA https://ibb.co/k3RYyA https://ibb.co/ma5hrV https://ibb.co/i9FhrV https://ibb.co/fpPxQq https://ibb.co/de0tyA https://ibb.co/gcKxQq https://ibb.co/kX48WV https://ibb.co/ijrYyA
  13. Hello everyone I am Elsa from China and i live in Washington D.C. now. I bought a dinosaur eggs from one of my friend in China and it took me $1500, it's very very big and heavy, but i have never bought fossils before now. If you can help me to confirm the fossils in the pictures below are authentic i would be very thankful. And if they are real what kind of eggs are they?
  14. Definitely NOT going to do "the tongue test!" I have found many "rocks" that seem to have multiple fossils in them... and this could be one possible reason- it WAS sticky and did contain food at some point? Once again, newbie here.... thoughts? Thank you!
  15. Kem Kem fossil bone

    This partial bone from Kem Kem was listed as unidentified but possibly Spinosaurus (no surprise there). It's a pretty substantial plate-like piece (154mm long). Not in great condition obviously, with missing material down one complete edge and likely in other directions. I've not really been able to work out what this might be but it has a distinctive concavity at one end and some surface structural ribbing running down one face. I've included an illustration that tries to show (with hatching) where the missing material was. Probably a long shot but maybe someone will recognize the surface ribbing and may be able to place it.
  16. Hello everyone I am a fossil collector but I have never bought fossils from online before now, so I am very skeptical of every fossil I see online. If you can help me to confirm the fossils in the pictures below are authentic (and are what they say they are) I would be very thankful. Thank you! Acheroraptor temertyorum (tooth) Pachycephalosaurus (tooth) Ankylosaurus (scute) Thescolosaurus (tooth)
  17. Is this a Nanotyrannus tooth?

    I got this from a guy who found it at Montana the Hell Creek area. I was wondering if it was a Nanotyrannus Tooth or a different carnivore?
  18. Fossilized Egg?

    I found this in central Iowa, not sure of exactly where. Kind of looked like an egg to me. It's more yellow on the inside with a kind of shell around it.
  19. Kem Kem fossil rib - dinosaur?

    This Kem Kem fossil rib I acquired a while back has obviously been re-assembled from multiple fractured pieces (with quite a lot of the dreaded Kem Kem filler) but the pieces look consistent, the surface preservation is nice, and the shape is pretty distinctive. It's 285mm long. Is there any way to determine what this might have been from or are ribs too generic? It was listed as dinosaur, but it could be crocodilian.
  20. Kem Kem fossil bone - phalange?

    This is a Kem Kem 'possible Spinosaurus' unidentified bone. Fairly poor condition with some liberal filler but some of the original shape is visible. Looking at known examples of Spinosaurus foot bones this seems like a poor match - it's just too broad and short, at least as far as I can see. However, it does resemble the shape of some other theropod phalanges I've seen. Another possibility, just based on overall shape, seems to be a crocodilian carpal bone. Can anyone shed any light on this?
  21. Your Favorite Find?

    Hey, I hope this is the right forum! I’m new to TFF, so idk if this is allowed or not, but figured I’d give it a shot. Admin, if not allowed, please delete and let me know. Thanks!! I’m curious to see your favorite piece in your collection. Post a picture of your favorite find, and tell me a little bit about it. What time period is it from? Where did you find it? (I.E., US, England, etc.) Is it rare? Why is it your favorite find? I’ve got a couple of favorites, but I’ll just post one. This rock in particular is teeming with history! On this one rock alone there are fossils of Crinoids, some with, what I believe to be, pinnules still attached. It’s got fossilized shells, imprints of shells, Crinoid stems, etc. Its my favorite because it’s just got so much history packed in to it! It was found in Boone County, MO., USA. I believe it to be from the Mississippian Era. These are all found on the same rock. (I’ll add some more pictures to the comments.) If I’m wrong in my guess on what they are, please correct me! I look forward to seeing your favorite find!

  23. I found this in Monmouth County, New Jersey (USA) last week and was wondering if anyone knew what it was. When I first picked it up, I thought it was turtle shell but the bone structure doesn't compare well at all with the other turtle shell examples I've found. The top part is what I was focusing on because it doesn't look that was formed as a result of breaks and wear to me. I guess it could be older breaks and if that's the case, I'm pretty sure that I'm out of luck getting an ID on it but I figured I would give it a shot. As always, all help is greatly appreciated! -Frank
  24. Teeth that are "easy" to id?

    Hi! Im wondering if there is dinosaur teeth that are relatively easy to id when it comes down to a specific species? Like a dinosaur with very odd or distinctive looking teeth that cant be mistaken to be anything else. I know that isolated teeth is often hard or impossible to id , but maybe there is some exception ? Best regards Patrik
  25. Mystery Judith River Dinosaur Bone

    Here’s one that has me scratching my head. It’s a bone I found in the Judith River Formation of Montana recently, I picked up these two pieces and later realized they go together. They’re definitely placed properly, but the shape is strange and I can’t ID it. My initial thoughts were some type of hadrosaur toe bone, but I can’t find any close matches online. What are y’all’s thoughts on this one?
