    Judith river toe/ungual/vert-process?

    Found in the JRF hill county - I always figured they were unguals of some kind and just never gave it much thought. But I really don’t know what they are. It’s been suggested maybe a part of a vertebral process? Any help would be awesome.

    VERY unusual tooth

    Hey all, This looks Dromaeosaurus to me, but we'll have to see if it's even possible to make that call without any posterior serrations. But the dramatic mesial twist that happens close to the tip and the general morphology give me hope. Also, curious to know what your take is on the posterior edge. The posterior serrations seem to have been sliced off. The serration-like indentations inside the slice itself look a little like they might come from the serrations of another individual's tooth (i.e., face biting or something similar). This tooth got seriously used!

    Mammal tooth ID needed. Cretaceous-JRF

    Hello, I have a number of Cretaceous aged mammal teeth that I would like to ID. Here is one I found recently in the JRF of Montana. I have a hard time taking pics of small teeth but I hope these are good enough for someone to ID it. Thanks for any help! It is about 3 mm wide.

    Judithian Theropod

    From the album: Dinosaurs

    A theropod tooth I recently acquired from the JRF. Sold as a juvenile Tyrannosaurid, but I'm not fully convinced.
  5. Hello, is this a fish scale? It is about 1 cm wide at the widest point. It is complete and very nice looking. Any help will be appreciated! Found in the JRF with crocodile, fish verts/teeth, turtles, and some dinosaur related fossils. It is very thin with the enamel (correct term for this?) present on the one side. Thx!
  6. Hello, I found this on my trip a few days ago to Hill Cnty, MT and need some help. It is a jaw, or tooth plate, that is 1.25" long. I wish the teeth were complete! I have provided several views but it seems that my phone can't take good pics anymore, I don't know what happened to it. It is annoying but these are the best pics I could get. Thanks for any help!

    Dinosaur toe bone ID needed! JRF find

    Pls help with an ID of this toe bone found in Hill Cnty, MT. I have taken several views of it and it is 2.25" long. It had been exposed for a long time and had a layer of lichens on it. Is it Tyrannosaur related, raptor, or ?? Thanks!
  8. Hello, I found this a few days back and need some help with it. It is actually a double sided tooth. I was thinking that it is probably in the Ceratopsian family?? Thanks for any help. Judith River Fmtn, Hill County, MT.
  9. Hello, these 2 scutes are from my trip a few days to the JRF in MT, Hill Cnty. I believe they may be Nodosaurid scutes but want a better informed person's thoughts on it. The one, I had to glue back together and am missing a piece on the bottom. I think it is interesting to see the pattern of the bone on the bottom of the one. Is the pattern from from how the bone cells 'grew'? Thx for any help!

    Fossil Bone ID needed - Judith River Fmtn

    Hello, here is a bone I found in the JRF about a week ago. It was found in a site with various dinosaur and crocodilian teeth. Thanks for any help. It is 3.875" long.
  11. Hello, I just had a trip to a co-workers place in Montana that I have looked at before with some good finds. It had been several years since my last visit and I was excited about possible new finds. In the sites I had found before, my dad, brother and I discovered some decent specimens. My dad did not find his Tyrannosaur tooth he wanted but he did find a couple of very nice raptor teeth. My brother found a few nice teeth but no theropod ones. As soon as we started looking, within a minute, I found a nice sized Aublysodon or Daspletosaur tooth. We looked for the day and then they h

    Hadrasaur jawbone section??

    Hello, I found this yesterday. I believe it is part of a Hadrasaur jaw. Please let me know if my thoughts are correct! Or not! Thx for any help.
  13. Hello, this is another Ankylosaurid tooth but what specific species? The tooth is the baby blue color in the last pic and has an almost unworn crown. It is about 12.5mm wide. Thanks for any help.
  14. Hello, I have a found a lot of gar scales but never one like this. Is it actually a gar scale? It is kind of rabbit shaped with no breaks or missing pieces. Thanks for any help.
  15. Hello, this is a very nice rooted Crocodile tooth I found a few days ago. Is this a Borealasuchus or Deinosuchus tooth. Or, something other than those. Thanks for any help!

    Tyrannosaur model

    Had an idea a while back to try and make a replica maxillary cast of a tyrannosaur and set some of my real teeth I’ve collected from the JRF in it. This was attempt one - took me about an hour. Wanted to see if it was worth putting more effort into it. Next step would be getting someone much smarter than me to help identify some of my teeth so they can be in the correct area of the mouth. I’ve got about 40 to choose from. For now, it was just to get an idea.

    Saurornitholestes langstoni

    From the album: Dinosaurs

    Saurornitholestes langstoni Judith River Fm., Fergus Co., MT, USA ~ 9 mm crown height This tooth has wear facets at the tip/apex.
  18. I'll start with the jrf vertebrae which I believe to be a hadrosaur cervical wondering if it is possible to narrow it down to a species if possible? And again anyone who is taking the time to look over these I thank you very much in advance.

    Frill? Chunkosaurus?

    My three year old was playing with a box of random Dino bones this morning and he handed me this one - which I hadn’t really paid attention to before. It seems like they’re vessel grooves on the smooth surfaces? I know it’s tough to see the symmetry on my pics, and I know it’s pretty chunkosaurus, but I didn’t know with the unique convex and concave surfaces including the unique surface texture if it was at all identifiable. Unique shape. Frill piece? Unidentifiable? judith river formation of northern Montana - milk river thanks folks

    Theropod jaw piece?

    Sorry about my not sweet picture skills. found Judith river formation of Montana - milk river. obviously a chunk of jaw, but we usually just find little croc jaws. This one is bigger, and the sockets just seemed theropod to me right off the bat. Grabbed a couple tyrannosaur teeth from my daughters display in her room and they fit like a glove. Super scientific, I know - but thoughts? thansk!

    Juvenile tyrannosaurid premax ID

    Hello all! I have acquired a very nice juvenile tyrannosaurid tooth from the Judith River Formation. I am fully aware that teeth from there are very difficult to be assigned a specie, but I was wondering if it could be narrowed down a little. Last time @Troodon was able to give me awesome info and help. The tooth is a premax tooth and is 1,7cm in length. I have a serration count for both distal and mesial sides: hard to tell for sure but it looks like 3/mm for the distal 4/mm for the mesial Thank you
