  1. Upon doing some research on exposures near Great Falls, and from a tip I received from a fellow member of my local prospector's group, I found an exposure just outside of Belt that is somewhat known for its plant fossils. Roadside Geology of Montana has this area of the state marked as early Cretaceous, but the large Jurassic coal seam cutting through the middle of this exposure was apparent as soon as I parked. I scrambled up the loose shale and sandstone to the seam, where I almost immediately began to spot small impressions in the dark-gray shale.
  2. The weather was promising, the husband wanted a good place to hike, and the dog had cabin fever. So I loaded them, along with my gear, into the truck and drove down to Crystal Lake to hunt around in the Madison limestone while the husband and the dog went for a romp in the Big Snowy Mountains. On the dirt road to the area, we drove past a mama black bear and her cub, hanging out only about 30 feet from the road. To avoid aggravating either, we didn't slow down to take pictures, but my husband was pretty "bear"-anoid about running into them again Well, the mountains weren't s
  3. A recent trip to the Madison Group near Yogo, MT turned up a small exposure for Mississippian fossils, mostly small crinoid hash plates but with a few little surprises. I'm still learning about different types of fossiliferous rocks; I believe this was an outcropping of limestone. I tried to locate these fossils in the National Audubon Society's Field Guide to Fossils, but I'd like to get an opinion from someone who knows much more than I do (which, let's be honest, isn't very much ) 01: These were the largest brachiopods I recovered from the site. Perhaps schuchertella? 02: T

    Big Hell Creek bone - a bit of a mystery

    So, this bone was collected by me earlier in the summer from the Hell Creek Formation in Montana. Upon collecting this bone I had thought that it was a Triceratops (or other Ceratopsid, I suppose) phalanx based on the shape and my memory of seeing pictures online. I was pretty confident in this ID up until a few days ago, and the following are throwing me: 1. This bone seems really big for a Triceratops phalanx. The other examples I can find online are not this large, but then again Triceratops was a pretty big animal and I’ve underestimated its size before. 2. It’s har

    Montana Mystery Fossil

    Hello from Louisiana! I am requesting help identifying a couple of fossils that were found in Montana. They were spotted while exploring the area with binoculars. The fossils were protruding out of the ground near an area with substantial erosion. Any ideas or suggestions as to what these two are?
  6. While out on a hunt in the Marias River Shale (Cretaceous) near Fort Benton, MT, I found what I believe to be either a holoscaphites or clioscaphites, based on the research I have done. The rocks in the exposure are quite segmented and eroded and don't take much force to break apart; a few small taps from my hammer made the rock, and the fossil inside, essentially fall apart into several pieces. My question is not one of ID, but rather of how to best prepare this fossil. From looking around this forum, it seems that many people use super glue for repairs that aren't very large. Wou

    Edmontosaurus jaw

    I just returned from a dig near Baker, Montana. I found this part of an Edmontosaurus jaw with the teeth replaced by siderite. I thought it was a rare replacement. If important, the KT boundary was very visible on this ranch. The section is about 3 inches by 3 inches.

    Miscellaneous Theropod Claw

    On the third day of our Hell Creek trip in Baker, Montana I stumbled upon a small theropod claw with identical blood grooves running down either side of it. Noel and I looked around for references but found no conclusive match for what it could be. It is 1.3 cm long, roughly .3 cm in width. @PaleoNoel

    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.

    This vertebra

    I was wondering if members with experience might give their opinion of this vertebra and to which dinosaur does it belong? I'm about to buy it. Location: North America, Montana, Powder River, Hell Creek Formation. Dimensions: 15.2 cm x 11.4 cm

    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.
  17. Taxonomy according to Schram and Horner, 1978, p. 394. Diagnosis (Schram and Horner, 1978, p. 394): "Rhinocarid of large size; carapace covered with hairlike ornament; furcae about 1 ½ times as long as the telson." Dithyrocaris rolfei, reconstruction from Schram and Horner, 1978, p. 395. Identified by oilshale using Schram and Horner, 1978. References: Schram, F. R. and Horner J. (1978): Crustacea of the Mississippian Bear Gulch Limestone of Central Montana. Journal of Paleontology 52(2):394-406. Factor D. F. and Feldmann R. M. (1985): Systematics
  18. Hello we are the Placers. These were found at Crystal park, MT. I just thought they were neat rocks but when I started trying to take the crystals out of them I notice what looked like an eye socket and skin. So I stopped immediately and did this. So many different pieces almost like it was a den of them. All of these are from around the same place.

    Nanotyrannus or T-rex?

    Hi everyone! So, yeah. I keep going back and forth on this one. I've been told it's Nano, but the serration count seems low for Nano (23 per cm distal 25 per cm mesial) and it looks a lot thinner than it actually is on account of a piece of the base missing. That and it's really big for a Nano tooth. Dimensions in mm are 50 x 18 x 11 Dimensions in inches are 1.97 x .71 x .43 The pictures are labeled rex because that's what I though it was originally. This is just bugging me so I'd like a second (or more opinion) just to put my mind at ease once and for all.

    T. Rex tooth?

    Hey guys, I bought this tooth as T.Rex from a reputable seller and a couple people have said it’s Rex but one also told me it’s nano because of the serrations. If I could get confirmation that would be very helpful thanks. Size: 1.18 inches Location: Garfield County Montana (hell creek)
  21. Hello again. What do you think? Do you see anything wrong with this tooth anything i should be aware of? Thanks
  22. Hey everyone! I know it’s a long shot, but I’m currently in Montana and will be for abt 1 1/2 more days, and was wondering if anyone had any ammonite sites in Montana, South and North Dakota, or Wyoming, I’d be willing to trade a spot, or take whomever it was out to Ernst quarries, or trade fossils for the site, if anyone’s interested in that, please let me know.
  23. i am going fossil hunting in Montana in June. i am wondering if there are any sites that yield good ammonite fossils in the eastern part of Montana(around Glendive, Baker etc.). if anybody could provide me with any information, that would be great

    Two Medicine Hadrosaur vertebra ID

    Hi! I got this Hadrosaur caudal vert from the two medicine formation. in Pondera County. I was wondering what part of the tail this bone would have come from? the seller says it is likely a proximal vertebra, but couldn't give any details on its placement. Is there any possible way you can tell what part of the tail this fossil belonged to? assuming a grown individual of the species. If exact placement isn't possible, Ill settle for general region. The centrum of the Vert is 2.7 x 2.3. x 2.2" and the process is 7.6" long in a straightline including the anterior points
  25. It's propably real and it has 10-15% repair. I don't know which species it belongs to (maybe Deinonychus or Dromaeosaur). What do you think?
