Dinosaur Park Formation and Belly River Group in Montana?
dinosaur man posted a topic in Questions & Answers
I recently learned that the Dinosaur Park Formation and in general the Belly River Group is in Montana! In parts of Kennedy Coulee, Milk River Badlands, is this true?

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?

Hi all! I got a digital microscope for christmas and I'm finally getting around to uploading the photos I've taken on it. Here are some closeups I took of a piece of bone I found when I hunted the Cloverly formation in Montana for a morning back on my first ever trip out west in 2013. Looking back on that experience with the knowledge I have now, I can truly appreciate what a rare experience I had as I've learned that this particular formation is rare to be able to hunt on. I'll tell the whole story of how my family and I made it onto this ranch in the first place, but that's for another time. Pics from the cross section: Pics of the surface of the bone:

I won't get to do much posting from the road, but since Mike opened the door showing off some of the wisconsin ordovician finds he found and helped my wife and I collect, I figured I would add a teaser from Glendive, Montana where I finally found my first ammonites in the Pierre shale south of town. This little guy was one of my favorite singles because its exposed on one side and completely encrusted with yellow selenite crystals on the other. I will take some clearer pics once we get home and get pieces cleaned up a little

Found yesterday near the milk river, Judith river formation. The biggest vert we’ve found for sure. Several other fairly large verts nearby that seemed to be hadrosaur, but not sure - and still 1/2 the size. Lots and lots of meat eater bones as well. -sorry the photos are rotated

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

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

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!!

My friend found this in Montana a couple of years ago. She thought it was an unusual roce. I think it is a fossilized turtle shell with some bones albeit very small bones. I tried my best to get decent photos.... Anyone want to weigh in on what it is? Thanks for any input.

I was going to wait until tomorrow night to post the 3rd tooth but i got around to taking some pictures and measurements now so here is Unidentified Theropod Tooth #3. Judith River Formation Hill County Montana Crown height 15 mm ( broken base ) Serration count 17 per 5 mm distal 20 per 5 mm mesial I do not see a twist in the mesial carina This tooth is more compressed than the other two teeth the first being dromaeosaurus. Saurornitholestes perhaps?? @Troodon
-
This is the second unidentified theropod tooth i just recently received. This tooth has a broken tip and its missing most of the mesial serrations. These are the measurements i observed followed by pictures for your own assessment. TOOTH 2 JUDITH RIVER FORMATION HILL COUNTY MT Crown height 12 mm ( missing tip ) Distal serrations are 3 per mm Mesial are 4 per mm There looks like there is a twist in the mesial carina Dromaeosaurus/Tyrannosaur?? @Troodon

From the album: Judith River fm. Fossil Finds
Probably my best find from that trip, this is so far the largest self found theropod tooth in my collection. It either belongs to Gorgosaurus or Daspletosaurus, though it is difficult to determine. Tyrannosauridae indet. (Either Gorgosaurus, Daspletosaurus or another taxon). Judith River fm.-

From the album: Judith River fm. Fossil Finds
One of my favorite finds from my trip to Montana last summer, a foot claw from an ornithomimid. Probably not identifiable beyond the family level. Ornithomimdae sp. Judith River fm. -
Planning another summer ramble across a wide swath of the US for siteseeing and fossil hunting. Going to hit some previous sites like Kemmerer and Big Cedar Ridge in Wyoming along with planned stops for a guided dino excursion at a private ranch in eastern Montana and a trilobite dig at Theisen quarry in Oklahoma. I will be zigzagging across much of Montana and Wyoming and would be interested in other suggested stops on the way if anyone has anything they are willing to share. Not looking for someones secret stash, just publicly known places the wife and I might be able to stop for an hour or two as we roll through. We will also be traveling through places like western Nebraska, Oklahoma, southern Alabama, etc. I am interested in any era, invertebrate, vertebrate, plant. Looking to expand my personal collection and maybe pick up a few pieces to trade or auction off here. I have the most flexibility while in the north, but I have been trying to see if I can detour to squeeze in at least a little Alabama carboniferous as I have seen many beautiful specimens posted and I love plant fossils. We shall see. I have the rockhounding guides for the northern states and have tagged several possibilities, I have also been combing through previous posts and searching other references online. I would love to identify an ammonite location along the way as I have never managed to collect one myself. Thanks in advance, Randy

Several of these are imbedded in the sandstone on the shore of a man made lake on the Missouri River. They are of varying size but fairly consistent shape. They are generally half-exposed as this one was. Any ideas?

Since I got such a quick response on my dinosaur tooth that was actually a rock I figured I’d check out some other stuff I found last week. Two separate bones pictured. Montana milk river area. From my basic anatomy knowledge it sure seems to be a scapula and then Some type of appendage bone? any thoughts? And I’m pretty sure these ones aren’t rocks if they are - I’m retiring from fossil hunting

First time hunting Dino bones and we found a bunch of stuff along the milk river in Montana. I have no clue what any of it is, but I know it’s all awesome A little about us: one of my daughters is 10 and is the only one I’ve been able to convince to love arrowheads, shark teeth, and dinosaur bones. We love being outside. I just chose a couple since I’m new here and want to see what I can find out. Thanks in advance. (we also found a huge 4 foot piece of beautiful petrified orange wood, lots of larger bones, toe bones, agatized bones, and what look like scapula, and heads of tibia and femurs). for now, here’s what I’d love to identify

I know virtually nothing about dinosaur eggs so bare with me. I figured this would be a good place to go to ask about an egg that I was told was an from a dinosaur. It was found in Eastern Montana by a family member. The exact location is unknown but it was in the vicinity of Glasgow, MT. Any insight would be appreciated.

Hi just got these two fossils today! And was wondering did I get it right on saying this Daspletosaurus tooth was a mesial tooth? Also i called it a Daspletosaurus because it’s DSDI was over 1.2 and I think it’s a mesial tooth. In the photo it’s beside my smaller Judith River Tyrannosaur indet tooth. Also is it possible to tell what this dinosaur finger bone is? Thank you! dinosaur finger bone

Found in over a dozen pieces. Had repaired after I glued it back together.

Hello everyone, On this edition of Rex or nano, we have this nice little mailbox score I got earlier this year. The seller and I are reasonably certain that it is a young adult rex. But I wanted to bring it to you folks to get your assessment. It matches the locality of Rex ( hell creek, from a microsite in Carter county) and based on my research from the forum and elsewhere it checks out as tyrannosaurid. (Ie: robustness and seemingly no pinch) Bonus question: I'm also curious on the placement of the tooth in the animals jaw. I have reason to believe it may be a right maxillary tooth.
