  1. Mystery dinosaur Horn

    Here's another Cretaceous western fossil that needs an ID. Its either from Hell Creek or Lance Creek (will have to check my records again), and I initially purchased it as a young triceratops nasal horn. After looking at it some more, I'm wondering if it might be an ankylosaur spike, or maybe something else. Thoughts?
  2. Do you think this item has any repairs and is it a genuine t-rex tooth? I t is 2 5/8 in lenght.
  3. Crocodile ?

    Hi all Can I get some help please. I purchased this little vertebrae for £1.05 no money but quite nice. the label says Crocodile Hell Creek, Montana . I just wanted to check.
  4. Mystery fossil (dinosaur? Cretaceous?)

    Hey all, Can anyone help me ID this fossil? It was found at an antique store with no information. Its density and coloration really reminds me of something from out west, like Hell Creek or Lance Creek. There's also a a semi-circle pattern of holes towards one end that reminds me of a crocodile's bite. Any thoughts on the possible ID or if its something besides a croc bite?
  5. Hell Creek Tyrannosaur tooth tip , nano ? rex?

    Hi! I have a tooth tip from hell creek formation but I dont know if its nano or rex, the serration count fits within the t-rex range with 2 serrations/mm , but I do think its quite slender for a rex tooth. What do you think? I tried my best to get a photo of the serrations but it wasn't very easy. The tooth tip is just 16 mm.
  6. Hell Creek crush plate?

    Fossil teeth found in the Hell Creek badlands of southeastern Montana! measures approx .42 inches long Amphibian? They are from uppermost Cretaceous age (Maastrichtian) deposits, in the Hell Creek Formation, Carter County, Montana. Any help identifying would be appreciated.
  7. Hey guys, I´m from Germany and have bought this little tooth from the Hell Creek Formation in Montana. The seller described the tooth as "Dromaeosaur tooth", which belongs possible to Dakotaraptor or Acherorator. I´m not sure about the identification of this tooth and hope, that you can help me. The tooth is 1,27cm (= 1/2") in lenght. Thank you in advance and kind regards!
  8. Seller listed this as a “raptor toe bone” and it looks like it to me as well. Found in Montana’s HCF. What do you guys think?
  9. Hell Creek Claw ID

    Hi Everyone, I'm after a second opinion on this claw I found in the Hell Creek, Montana this summer. It's 1.83" in length and has cleaned up nicely. My guess is that it's from a large reptile like a crocodile or turtle. Gut feel says croc like Borealosuchus. Any thoughts?
  10. 1.25" Rough Nanotyrannus Tooth I.D.

    Hello TFF! This is my first post (finally just made an account after some technical difficulties, thanks @Fossildude19 for your help!) although I've been reading up for the past few months on this site. I am looking to purchase this Nanotyrannus tooth from an auction site, and I have included all of the pictures provided on the listing. I understand that this is a very rough tooth (the seller clearly states this as well and doesnt try to mislead in the slightest) and I just want to make sure that it is actually a Nanotyrannus tooth. The seller states it is from the Hell Creek Formation, 1.25" long, feeding worn tip, and wear grooves from the opposing teeth. The seller also states that there has been no restoration/repair done, other than some fossil glue used to stabilize the tip, and a COA can be included following purchase. I'm just looking for confirmation that it is a nanotyrannus tooth, or even a tyrannosaurid tooth. I tried to include all of the info I.D. posts usually need, but if I missed anything please let me know. Thank you all for your help! I really appreciate it!
  11. Hell Creek Digits

    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!
  12. Nanotyrannus or Dakotaraptor?

    Hi all, I am new to the forum and new to collecting =) I recently obtained this nice tooth labeled as Dromaeosaur sp. premax. tooth - I would like to get a more refined ID if possible. It was found in the Hell Creek Fm., Powder River Co., Montana and measures 15/16". Denticle count per 5mm is distal 18, mesial 24 (not many denticles visible mesial though). I found a thread here stating it is possible to distinguish Nanotyrannus from Dakotaraptor teeth by the shape of the denticles - however I find this very hard as rookie. Any help is appreciated!
  13. 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)
  14. Good morning everyone. Could anyone help me ID this tooth? Because it has me stumped. Unfortunately I still have to learn lots before I can ID these ceratopsian teeth (morphologicaly they can be tricky). My first guess was cf. Leptoceratops gracilis because of the tooth's small size, it's only just over half an inch. But now I'm reconsidering this guess because maybe it's a juvenile Triceratops tooth? The lack of a root makes this tricky because I know Triceratops teeth have two roots while Leptoceratops teeth have only one. Plus the highly pronounced verticals ridge is making me lean towards Triceratops once more. Any ideas? Thank you!
  15. Dakotaraptor tooth?

    I came across this tooth and was wondering if the ID is correct as I haven't had much first hand experience with raptor teeth so far, especially Hell Creek raptors. It's being advertised as a Dakotaraptor steini tooth from the Hell Creek formation. In the description it says it has very fine serrations though I find them hard to spot in the photos as they are a little on the small side. It's pretty small. So could it be Acheroraptor instead?
  16. Tyrannosaurus rex

    More pics of my rex tooth
  17. Edmontosaurus Pubis

    Right pubis of an Edmontosaurus.
  18. I found an interesting Thescelosaurus tooth online. No locality was given other than the fact that the dealer claims that the tooth is from the Hell Creek formation. What do you guys think?
  19. Process IDs

    Can anyone possibly ID these processes? Are they from different species? I know it's a long shot, but I won't know unless I ask. They're from hell creek. that's all I know about them. The first one is 2.75" tall, and the second is 3.25" tall. That's all the information I have about them.
  20. Worn Down Theropod Tooth

    A couple of years ago my grandmother purchased me this theropod tooth offline for a cheap price. The only locality given was Hell Creek, Montana. I took it to my local geology museum and one of the paleontologists who took pictures of it for me told me that the serrations were nearly identical, but he said that it is a dromaeosaurid tooth in his opinion. I think it could be either nanotyrannus, dromaeosaurid or maybe just a theropod indeterminate. It is very worn down. What do you guys think?
  21. I found a dealer who is selling a Richardoestesia Isosceles tooth from the Hell Creek Formation of South Dakota, but I just wanted to make sure whether is is real or not. Is it? The dealer also claims that this has not been restored and is a complete tooth.
  22. Pineapple Turtle Shell?

    Just found this in glendive Montana. It's thin like turtle shell but has several raised sharp adornments, resembling pineapple skin. Two of the sides are completed edges, while two are fresh breaks. It doesn't match up with any of the common turtle species I could find. Any ideas?
  23. Dromaeosaurus Teeth?

    Hi everyone, I am looking to get a Dromaeosaurus tooth and found 2 that are labeled as such. The serrations look different to me so I am not sure which one I should go with. I did browse through some old threads and saw some discussions about Dromaeosaurus not being found in Hell Creek which only confused me more. #1. Hell Creek, Harding County, South Dakota #2. Hell Creek, Carter County, Montana
  24. Hello forum, new member here! I have been lurking for a while and concluded that some of my Hell creek fossils are probably mislabeled. Bought them back in 2005-09 from a Danish collector. The three small theropod teeth were labled as follows: smallest one, at 11 mm long and 6mm at the base; Saurornitholestes. (Hell creek, montana) Second largest at 15 mm long by 8mm; Dromaeosaurus.(Hell Creek, Montana) Third one is labeled as Nanotyranus, but with a length of 15 mm and a 9mm base, it seems quite small. ( Hell Creek, Roundup, Montana) The middle tooth has faint ridges, the cam is not picking up, running from top to bottom (Acheroraptor?) Would love to hear your opinions on what these could be!
  25. Saurornitholestes Tooth?

    I picked up this tooth a while ago and the description was raptor tooth from Hell Creek. I was thinking Sauronitholestes (Wow that’s hard to spell with autocorrect messing me up) but hopefully you guys will help Id it. Thanks! {sorry about the picture quality if it is too bad I totally understand}
