  1. Hi, more fossils from my collection. The first two pictures are of a pyritized Ammonite from Buttenheim, Germany and is from the Jurassic. The next two are of a pyritized Ammonite from the Volga River, Russia and is Jurassic. The next picture is of Marston Marble. The second to last and the final is Beringiaphyllum cupanoides from the Fort Union Formation in Montana.
  2. The Two Medicine Formation is a late Cretaceous geological formation that was primarily deposited in North Central Montana 84 to 71 million years ago about the same time as the Judith River Formation, See Map - pink area. The Two Medicine is found along the east flank of the Rocky Mountains and represents the upland area of the Cretaceous Seaway while the Judith River Formation represents the lowland area. Although deposited in the roughly the same period the Two Medicine has yielded an amazing list of dinosaurs that are not found in the Judith River. These include Einiosaurus procurvicornis,

    Crocodilian, Turtle, or Both?

    I recently acquired a bunch of matrix from the Cloverly Formation of Carbon County, Montana. And came across a few scutes. I’m not fully sure if they are turtle, crocodile, or maybe both, which is why I thought I’d share them here.
  4. Hello everyone! My name is Weston and while I studied Geology at Whitman College, I never continued by degree. I am now getting a nursing degree and was stationed in Jordan, Montana for rural clinical. A contact of mine let me dig on land and I found all these fossils. Here is a link to my google drive photos. Please help me ID everything and anything you can. I am wondering if the things that look like eggs are actually eggs, as well as what the perfect sphere is. I am also wondering what dinosaur the bones most likely belonged to. I am confident there are coprolites right? I am
  5. Hi everyone! Here's another little tooth that has me stumped. It has a pinch like a Nano, but the serration density is what I've come to expect from a raptor. At least I got some really nice shots of the serrations! CH: 8 mm CBL: 5.5 mm CBW: 2 mm mesial serration density: 6/mm distal serration density: 4.25/mm So what do you all think? Nano? Dakotaraptor? Tyrannosaur/Dromaeosaur indet.? Any insight is appreciated as always!
  6. Hi everyone! This came from Powder River County, Montana Hell Creek Formation. CH is 12 mm (I think, not sure where the root begins.) CBL is 5 mm CBW is 2 mm no serrations on the mesial side but there are some on the distal side but only in the middle and not near the tip. The density is 7/mm. I have a two others like this I'll try and post pics of later. one other has full serrations on the distal side (7/mm) and some very light serrations at the base of the mesial side (7/mm) and another that's fully serrated on both sides (7/mm on both sides) Other than
  7. I have a few vertebrae I was hoping to get identified. These are 3 that I don't have any others that are alike. I tried to search online and the oval shaped one looks like possibly a Pachy but wasn't sure. These were all found on the Judith River Formation Montana, Hill County. first 4 is the one that I thought was Pachy, 2nd 4 I am not sure, 3rd 4 might be Hadrosaur?

    Where to find opalized wood?

    My family and I will be going on a trip to Montana and Wyoming this summer. I plan to do a lot of collecting for both myself and paleontology lab I now work for. We're planning out the trip now, and wonder if anyone can recommend a good spot for finding opalized wood. A collector recently donated an absolutely gorgeous limb cast for our collections, and my son is in love with it (so am I!). We know that The Gallatin Petrified Forest allows a small amount of collecting with a permit, but is there anywhere else we can find some?

    Judith River Theropod Tooth

    Hey guys, I obtained this tooth at tucson this year direct from the finder. It is from the Judith river formation, hill county, montana. 2.2cm long. got a characteristic V shaped flattened area on each side of the tooth, which i have seen in nanotryannus but it can't be that ? as nano doesnt occur in the judith river.... or it's has been mislabelled? My question is tyrannosaurid or dromeosaurid? if so what could it be? thanks for your time. @Troodon

    Hell Creek Small Theropod Claw

    Hi everyone! I wanted to post one of my new favorite finds from this past week of collecting in the Hell Creek formation of Montana. I found this little partial claw at a microsite which proved to be quite productive, making for a great day. While the articulating surface is missing, I still feel that it could be identifiable and my first guess is bird. Avisaurus in particular as I remember seeing similar claws being labeled as such on other platforms. It’s about two centimeters long and the bottom is flat, giving it a somewhat triangular cross section. photos from the field.
  13. 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

    Is this a Leptoceratops claw?

    Hi everyone! After I posted some claws earlier, Troodon directed me to a very helpful link on identifying HC dino claws and while I was there I noticed something really interesting. See, those claws also came with a claw from an herbivorous dinosaur which I just chalked up to Thescelosaurus until I saw pics on the thread of Leptoceratops claws. Before I make that leap, I'd like a second opinion though. The piece is from the Hell Creek of Powder River County, Montana. I included pics from the thread of Thescelosaurus and Leptoceratops side by side with mine to show my reasoning. Any

    Unidentified Theropod Tooth

    Hi Everyone, I recently purchased this feeding worn theropod tooth that the seller had listed as unidentified, with it likely being a Tyrannosaur tooth. It is .42 inches long (straight line) and comes from Hell Creek. I was thinking it might be a Acheroraptor tooth, but its tough to tell due to the amount of feeding wear and enamel damage. I was wondering if anyone else could help me concretely identify it. Thanks!

    Are any of these raptor claws?

    Hi everyone! I acquired some dinosaur claw partials and am trying to learn to tell them apart. There are a few different morphologies so not all of them are Anzu (I think). Any insight would be greatly appreciated! The length measurement given is from the tip to the top of the base in a straight line Upper left, first pic set: 24 mm Upper right, second pic set: 21.5 mm Lower left, third pic set: 29 mm lower middle, fourth pic set: 25 mm (probably Anzu) Lower right, fifth pic set: 26 mm (also probably Anzu)

    Leaf fossils identification

    I'm looking for help in identifying some leaf fossils/impressions I found in the Fort Union formation in Montana. Most were found in S.E Montana. There are many different kinds. Can someone help me identify them? Can someone give me a good point of contact for someone? Here are several examples. Tia.

    Help identifying this tooth

    Last summer I found this tooth on the Boulder River in Montana, any help identifying it would be greatly appreciated. Thanks for looking!

    Tooth Identification

    Here is a small tooth collected from the Hell Creek formation, Garfield Montana, likely a juvenile. I think from its properties that it is a Nanotryannus. I would appreciate your thoughts.

    Cretaceous Mammal Tooth Fossil ID Please

    Hi, I recently got this cretaceous mammal tooth from the Hell Creek formation, and I was wondering if you may help me find the scientific name of the species that it belonged to. I've done some research and learned that it was the premolar of a Multituberculate mammal. This order of mammals was diverse and there were many species. I think it might be one of the members of the Genus, Mesodma, Yet I could be wrong. I tried to narrow it down to the exact species, yet there are few examples to help me pinpoint to a certain Id. This tiny tooth is from Garfield County, Montana. it is from the late c
  23. Hi everyone, I wanted to get some opinions on this piece I found in Montana's Hell Creek formation this past summer. My initial thoughts were that it was a ceratopsid skull fragment. It was a fossil I was planning on selling, but before I do I wanted to rule out the possibility that it was a piece of ankylosaur osteoderm as I have significantly less material from that clade of dinosaurs. The dimensions are about 8 cm by 7 cm.
  24. Hi everyone, About a week ago I posted pictures of a tiny carnivorous dinosaur tooth from Hell Creek thinking it was raptor and it wound up being Tyrannosaur. Since then I've been taking a closer look at my other tiny teeth and this one which I thought was Acheroraptor stuck out to me when I took a closer look at the serrations. It also occurred to me that there are serrations (although very worn that I for the life of me could not get a decent shot of but are present) on the anterior carina which you don't see on Acheroraptor teeth so now I'm leaning more towards a tiny Tyrannosau

    Bizarre Hell Creek Denticle?

    Hi all. I know it's been a long time since I've posted anything on the forum, but now that I'm back from college I'm planning on being more active. Today I wanted to post this odd fossil I found this past summer at a Hell Creek formation microsite in eastern Montana. I've never seen anything quite like it before, but my guess is that it's some odd denticle from a cartilaginous fish of some variety OR alternatively it could just be an odd fish tooth (maybe pharyngeal?). It measures about 4 mm from base to tip and a little bit over 1 mm at its widest. Any input would be appreciated. -Noel
