  1. Good evening to all my paleo peers! Tonight I’d like to share with you a selection of some of my favorite fossils found this year. I was lucky enough to spend three weeks in Montana over the summer, along with a few other fossil hunting opportunities here and there. As we hop into the New Year I'll kick things off aptly... Frog Radioulna-Judith River formation, Montana One of my all time best single fossil hunting days was spent in late June on a microsite in the Judith River badlands of northern Montana. Among the teeth of crocs, hadrosaurs and dromaeosaurs was this absolutely tiny

    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.

    Tiny Judith River Theropod Teeth

    These teeth were sold as a baby tyrannosaurid and a dromaeosaurid/bird respectively. Some other specimens from this lot have been posted here if I recall. But they are from North of Havre, Montana close to the Canadian border. Apparently they are from quite an old collection from around 1950-70s. The provenance should place it solidly in Judith River Formation. Since these teeth were selling somewhat quickly, I just grabbed them and decided on figuring it out later. The first tyrannosaurid tooth does have some similarities to Dromaeosaurus with the mesial twist, but I could be wron

    Tyrannosaur tooth Judith River

    This tooth was purchased on an auction website from a person who needed the money and sold a tooth they purchased from a reputable online dealer in 2020. All I have is an original receipt from the reputable dealer which lists Tyrannosaur tooth, Judith River Formation and the original price. Here are some pictures I just took as I just received the specimen. I am wondering if it is possible to determine the species. Thanks in advance

    Dromaeosaurid humerus?

    Hello folks, Any ideas on genus/species identification of this humerus? It's 14cm long, hollow, found in Judith River formation, Hill County, Montana. It was identified as "Dromaeosaurid sp. indent" by the seller. Possibly Dromaeosaurus albertensis? It looks very similar to the first museum skeleton below, and fairly similar to the second - although the humeral head is less prominent. However, the morphology in the third and fourth museum Dromaeosaurus examples looks completely different, so I'm not sure what to make of it.

    Daspletosaurus tooth?

    Hello, a quick question. I bought this tooth as Daspletosaurus tooth 2 1/8. it was found in the Judith river formation (exactly?) is it conceivable that it is also a Gorgosaurus tooth? Or is it even possible to determine exactly? I would be very happy about your opinion. Best wishes.
  7. Hello . Is this tooth a Ankylosaur or a Nodosaur tooth ??? Locality : Hill county , Judith river formation Thank in advance !
  8. The Judith River Formation is a late Cretaceous geological formation that was primarily deposited in North Central Montana 80 to 75 million years ago about the same time as the Two Medicine Formation, See Map - Large meandering rivers flowing into the Intercontinental Cretaceous Seaway deposited the Formation. Much of the area was very flat, with swamps and bogs, much like today's southern Louisiana. Dinosaurs included Tyrannosaurs, the duck-bills hadrosaur Brachylophosaurus was the most common found, Ceratopsian included Avaceratops and smaller theropods like Tr
  9. These are a couple smaller vertebrae and a bone I found on the Judith River Formation, I was hoping to get an opinion on what dinosaur they would be from. Thanks.
  10. Hello. I was wondering if anyone could help me identify this tyrannosaur tooth I recently added to my collection. It is said to be from the Judith River formation in North-Central Montana. Unfortunately, I don't have the county it came from. The tooth has the following measurements. Thanks for your help. CH = 40 mm CWB = 10 mm CBL = 16 mm MC = 18 denticles/5 mm DC = 14 denticles/5 mm DSDI = 1.29
  11. Hey everybody! I wanted to make a thread sharing with you some of the smaller fossils in my collection, many of which I've photographed using my digital microscope. Some of these I've found in the field at microsites or channel deposits, while others I've found at home searching through matrix. I hope you enjoy! Our journey begins in Wyoming's Lance formation: A Pectinodon tooth my dad found in 2017. A tooth that was identified by other forum members as potentially Avisaurus, also found in 2017. A tooth I initially called Paronychodon, although the small &

    Another Judith river matrix tooth.

    I was looking through my biggest piece of matrix from Judith river (it’s filled with shells unlike the other ones) and I noticed this poking out. It was very easy to remove. This doesn’t look like the two other shed teeth I have is this one unworn with a root attached? And is it also a ceretopsian? .4 inches long.

    Judith River Hadrosaur tooth?

    I’m working on another piece of Judith River matrix that I got at the Denver show this year. I think this could be considered one of the better pieces it’s one of the larger ones for sure. It’s shy of a half inch long somewhere between 0.3 and 0.4 inches, but there is more to expose at the base.
  14. I found this in the Judith River formation last weekend near the Milk River, I assumed it was just croc scute but it is thicker and different texture, maybe its turtle or a different kind of croc. @patrickhudson thinks its dinosaur skin but I doubted him.

    Judith River Ceratopsian tooth?

    I just got another possible Judith River shed tooth out of a different piece of matrix. While in the matrix ceratopsian was suggested. I’m hoping it’s not a pebble this time. Just over a quarter inch in length

    Ceratopsian Frill?

    I am fairly certain this is got to be Ceratopsian frill. It was found among about 1000lbs of ceratopsian bone but wasn't sure. It was found on the Judith River formation on the Milk River. Anyone know? I have about 10 pieces similar to this. @patrickhudson @Troodon

    Judith river claws?

    Found in the Judith river formation along the milk river. They seem to be a few claws, but unsure about the dark one that’s super hollow as well as the first one that seems to be a bit more uniquely shaped than I’m used to finding. I thought croc claw at first based off what we were finding in the area - but who knows. All three are about an inch long. thanks for the help. Deciding if they’d be worth restoring or not. sorry for the slight mix and match on the photo order

    Judith River Herbivore teeth

    I posted in the fossil prep a few days ago about some Judith River matrix I got with teeth. Well now that I practiced on a damaged tooth shard I decided to start on this piece which seems to have two teeth laying on top of each other. I was hoping to get some help on what species these could be. I believe there is an ankylosaur tooth in good condition under the tooth that is more exposed. The small one is about a quarter inch and the larger underneath about 0.6 inches. this material is new to me and I have more matrix with different teeth so any other input is also helpful.
  19. I recently acquired some matrix with teeth from the Denver gem and fossil show this year. I’m unsure what is best to do. Leave everything in the rock, get the teeth out and see if I can find other fossils as well, or just prep the teeth out a little and leave them in the matrix. I have prepped a lot of Moroccan phosphate material but never something from the states. Also if anyone can help I.d any teeth that would be helpful. Here are a few of them.

    Weird and tiny dino bone

    Milk river Judith river formation dinosaur bone. It’s about 1cm, has what seems to be a tiny foramen. At first thought it was some type of broken part of a vertebrae - but I really have no clue. Any help would be awesome. Thanks

    Judith River Tyrannosaur

    Hello, I am interested in this. Tyrannosaur from Judith River, Hill County. 2.5 cm. Seller says Gorgo or Daspleto (I guess it is impossible to tell which) but is it a Nanotyrannus instead? Because of the indents on the base. Tip is repaired, but any restoration? Thanks

    New additions to my collections!

    Hi everyone! I want to introduce some new additions to my teeth collections. 1. Nodosaur tooth from Judith River Formation This tooth is from Hill Co. Montana. Has nice set of serrations, and 10 mm wide. There are two genus of Nodosaur known from Judith River F. : Edmontonia and Palaeoscincus, thus, this is a Nodosaurid indet. 2. Pygmy sperm whale (Kogiopsis) tooth from Hawthorn Formation This tooth has no tip, but have enamel and root. This is slightly larger than 3 inch

    Dromaeosaurus albertensis Tooth

    This is my first attempt at getting a Dromeosaurus albertensis tooth from Judith River fm. I've largely been avoiding buying dromeosaurids like the plague that aren't Acheroraptor or Saurornitholestes. Provenance: Hill County, Montana The tooth is repaired, and I had to realigned it while restabilizing it with butvar. The tooth doesn't seem to perfectly fit together, or too much butvar ended up in-between. There does not appear to be any serrations on the mesial edge, and it doesn't appear to have any trace of serrations, at least not that I can see with a macroscope.
  24. Two Tyrannosaurid teeth that I ordered early this week has arrived. This is the first tooth that I want to show, which is a tooth of a juvenile Tyrannosaurus rex (or Nanotyrannus). Since I personally believe that the Nanotyrannus is an invalid genus, I think this is a juvenile Tyrannosaurus rex tooth. For those who do not agree, this is a Nanotyrannus tooth. This tooth is from Hell Creek formation of Garfield Co. Montana. This is an 1-3/8 inch, and has some chips and scratches at the labial side, but I think this is still a great tooth.

    Three possibly mislabeled teeth

    These three are from Milk River, Hill County, Montana of the Judith River Formation. Seller has the first two labelled as Albertosaurus---So I am guessing they are actually Daspleto/Gorgosaurus and number 3 is sold as Centrosaurid, would I be right that Centrosaur isn't from Judith River and it should be unidentified ceratopsid---I notice there are quite a few found in Judith River. I'll put them ins eperate posts because there are a lot of photos supplied, which I hope will be helpful. Seller has been responsive in the past, so I can likely get addit
