  1. One more milk river Montana find

    Another milk river Montana Judith river formation bone. Found with the rest of the bone, but it was all chunked and eroded out. This is the size of a large hand. Thought it looks like the end of a long bone - maybe hadrosaur because they seem to be the bigger Dino’s in that area - but it didn’t seem to fit in my search. thoughts?
  2. Milk river tooth/claw?

    A milk river, northern Montana Judith river formation find. Size of a dime - and these are about the best pictures I can get. Thought it was a raptor tooth at first, but the side looks claw ish. Or maybe just broken? Thoughts?
  3. Judith river Montana bone?

    Found near the milk river in the Judith river formation of north central Montana. it’s just weird. Doesn’t look like bone, but it doesn’t look like petrified wood either. Had a paleontologist friend look at it and he was a bit stumped. thoughts?
  4. A selection of Hadrosaur teeth

    Hello, a selection of Hadrosaur teeth I'm interested in. Seller is uncertain of species on most, so any thoughts appreciated. 1 - From Judith River formation. 0.3 inch 2 - Judith river. 0.6 inch. Seems same species as 1? 3 - Judith river. 0.7 inch This one, it doesn't too clearly but seller says the tooth has denticles on the rim of the crown resembling Gryposaurus, but says Gryposaurus isn't from this formation yet. This one interests me most. 4 - Lance Formation. 0.8 inch. This one, seller is confident to be edmontosaurus. Many thanks
  5. I am a fan of feathered dinosaurs and I had really wanted to get a fossil from a feathered dinosaur, the fluffier the better. Anzus are already on my list but as a student i cant get one with that price tag Something like a Raptor(dromeosaur like dinosaurs) would be good,but Im open to feathered ceratopsids therizinosaurids etc Doesnt matter what fossil it is,could be bone or claw or tooth,any suggestions?
  6. One more Judith river weirdo

    One more odd one - again, Judith river formation northern Montana. Weird asymmetry that’s got me wondering. Found in the same location as a bunch of other Dino bones - almost like a washout. Crocs, meat eaters, hadrosaurs, all in the same a spot
  7. Ceratopsian frill?

    I posted this a while ago, but I’ve cleaned it up and taken a different angle of the agatized inside. Montana milk river Judith formation. It seems to have the vessel grooves on one side, but is obviously very worn. Agatized heavily only the inside but even visible from the outside. the agatized portion looks super similar to another bone found in the area (fourth pic). I don’t know how the agate process works, but the one the fourth picture that sure seems like a bone has the same agate characteristics as the “frill” -or... maybe it’s a rock again- fourth picture is a different “bone” just to show the agatization
  8. Judith river vert

    A couple of verts from the milk river Judith formation. Different shapes - assuming different dinosaurs. I know they’re a bit broken up, but just curious if anyone can tell what they’re from based odd the pics alone. first four pics from one vert, last three from the other thanks!!
  9. Dromaeosaurus? Judith River

    Hi all, I recently acquired this tooth labeled as Tyrannosaurid indet. It is 0.5 inch (1,27cm) in length and was found in the Judith River Fm, Wheatstone Co., Montana. The a-typical placement of the mesial carina led me to purchase it thinking it could be a Dromaeosaurus albertensis premaxillary tooth. Serration count over 5mm is 16 mesial and 15 distal. What do you guys think?
  10. Judith River Ceratopsian Spitter

    Hey everyone, I found this spit tooth in Montana's Judith River formation over the summer and believe it belongs to a ceratopsid as it looks similar to ones I've found in Hell Creek and Lance. This would be cool as they are significantly rarer in this formation than in HC & L , despite a wider variety of species. Let me know what you think. It's about 1.5 cm long and 1 cm wide.
  11. Tiny Judith River Tooth

    Here is a small, 3/16" tooth from the Judith River Formation. I'm not quite what it is. I think it's a fish tooth but not sure. Any ideas? (no serrations present)
  12. Hadrosaur Humerus Repair/Prep

    I recently got this lovely mess of bone, which is a mostly complete hadrosaur right humerus that only requires some assembling. I actually bought this with the idea that it might be a fun project. But then it broke even more in the shipping. So I have my work cut out for me. It's from Judith River formation, Montana. It's hard to tell at the moment, but it seems to be a rather slender humerus. So that would make it more likely to be from the saurolophinae subfamily. But I will look into that some more when I have it assembled. So I will be doing lots of reassembling on this piece as well as prepping away some excess matrix that's still present. Besides the obvious problems, the bone itself is actually in very nice condition with some really smooth cortical bone as well as some lovely visible muscle scars. This is how it looked when I first opened it. Quite a mess. Also a drawing of what it should look like in context. And here I have slightly ordered the pieces. There's 5 big main pieces, three medium pieces and a whole bunch of tiny chunks. One of the bigger pieces that includes the ulnar and radial condyles. The shaft of the bone has had a pretty bad recent fracture. This is also where most of the smaller pieces come from.
  13. I just wrapped up my awesome 3 week fossil hunting trip with Paleoprospectors and I'm excited to get home and share more of my finds with everyone. It was an ambitious undertaking on my part as I would be out fossil hunting in hot and dry conditions for such an extended amount of time with no parents within a thousand mile radius, that's not to say I wasn't looked after and I'd like to thank all of the staff and participants that accompanied me during this excursion. Tonight I'll share with you the pictures and stories from the last three days of my time in Montana. Wednesday involved a lot of hiking and not a lot of production in terms of fossil finds, my best finds included a shred of theropod tooth, a small fragment of theropod bone and some petrified wood pictured below- Here's a view of small portion of the area we were hunting My group decided to call it a day early as it was 105 degrees Fahrenheit in the valley at one point making hiking nearly unbearable.
  14. A Few Small But Cool New Dino Fossils

    We have been working primarily on our shark program material but we did add a few new dinosaur fossils. For the most part they are pretty small in size but add quite a bit to the education we do. These represent some iconic and scientifically important dinosaurs. In addition to these small fossils, we added a 6" Trike frill piece from HC, a smaller piece of a Horseshoe Canyon Ceratopsian frill, and a 2.5" Hadro vert from that formation. These are excellent touch fossils so I am happy ! The small fossils are..... Dromaeosaurus sp. Judith River. I big thank you thank you to @Troodon for some ID help. This is a really nice tooth and I am really excited about this one. We can get into some fun science about the study of tooth wear in determining what dinosaurs ate.
  15. Dromaeosaurus Tooth?

    Hi folks, I've seen a tooth for sale listed as a Dromaeosaurus Albertensis. I trust the seller's ID, but I'm not 100% confident with dromaeosaurs, so would just like to hear what the forum experts think? Locality: Judith River Fm. (Havre, Montana) Size: 2cm These are the only photos, I'm afraid. There is apparently a twist in the mesial carinae, but it's not super clear. Thanks in advance, guys!
  16. Crocodile Osteoderm

    From the album Judith River fm. Fossil Finds

    Here's the second piece of crocodilian osteoderm I found in Montana in the summer of 2017. It may also be from Leidyosuchus.
  17. Crocodile Osteoderm

    From the album Judith River fm. Fossil Finds

    This osteoderm may belong to Leidyosuchus.
  18. Tyrannosaurid Tooth Tip

    From the album Judith River fm. Fossil Finds

    Here we have the tooth tip from a Tyrannosaurid I found at a microsite in Northern MT. Teeth, especially fragmentary ones like these are nearly impossible to identify accurately as the differences between those of Gorgosaurus and Daspletosaurus (the two species of tyrannosaur from the JRF) are difficult to distinguish.
  19. Leidyosuchus tooth

    From the album Judith River fm. Fossil Finds

    This little tooth likely comes from the alligatoroid Leidyosuchus. However I could be wrong and I'm basing that idea off of it being the only crocodilian other than deinosuchus described from the formation.
  20. This is being sold as an aubsylodon tooth with partial root (which I’m not sure is even possible as the genus is apparently only recognized with one premaxilla tooth. How does it look?
  21. judith river fossil, scute?

    A weird looking fossil I found last summer in the Judith River Formation.
  22. Dinosaur Verts (Maybe)

    I need some ID help/education. I saw a few vertebra for sale and they are in my price range so I thought I would put them on the forum and gather some more informed opinions about these. First up is a "Raptor" vertebra from Hell Creek. It is around .8" x.5" inches. I lack the skills to determine if it is dinosaurian let alone raptor but my gut says likely not.
  23. Micro Bones

    From the album Judith River fm. Fossil Finds

    I have no idea what these tiny bones belong to. They could be bird, mammal, small reptile or an amphibian. These were found at the same microsite as the Troodon tooth. If you have any indication as to what these could be let me know.
