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

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. Pics I just took from the motel. Unguals from the paper describing Mirarce, a close relative of what’s present in Hell Creek. I’d love to read some opinions.

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. I don't think it's Saurornitholestes sp. due to the serrations not having the distinct hooked shape. I'm not 100% sure whether or not it's Tyrannosauridae indet., but I don't think it is, but the robust dromeosaurids are supposedly very similar at first glances. Any help or clues is appreciated. If any pictures are insufficient, I can try and take better photographs.

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.

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.

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)

Hello again. What do you think? Do you see anything wrong with this tooth anything i should be aware of? Thanks

Ammonite sites in Montana, Wyoming, North & South Dakota!
PrehistoricWonders posted a topic in Questions & Answers
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. -
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 of articulation. As always I can provide more detailed pictures/measurements of requested parts of the specimen.

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?

Hello all, it's been a very long time and I'm posting from my phone in an area with no wifi, so I hope I've followed all the rules as best I can. I was out fossil hunting in the Upper Hell Creek in eastern Montana last year, and found this bone. (Sorry for the images, I will not be able to retake them for months.) It was found in a sandy mudstone and appears to be hollow (and very crumbly). Its about 10 inches long.My best guess is a Struthiomimus femur, but if anyone knows different please let me know. Thank you for any help you can give!

Found this little guy in the two medicine formation of north central Montana. What animal has very similar molars to humans? It looks like a lower molar - or is it a concretion molar? Ideas? Thanks for any info.

My three year old was playing with a box of random Dino bones this morning and he handed me this one - which I hadn’t really paid attention to before. It seems like they’re vessel grooves on the smooth surfaces? I know it’s tough to see the symmetry on my pics, and I know it’s pretty chunkosaurus, but I didn’t know with the unique convex and concave surfaces including the unique surface texture if it was at all identifiable. Unique shape. Frill piece? Unidentifiable? judith river formation of northern Montana - milk river thanks folks

Greetings Found this section of Dino bone in a local antique shop. It was from an estate of a man who found it and a few others in Montana in the 1950s. Thought it was cool and it was listed as a Hadrosaur bone. Some great colours. I have included end shots to show the marrow in cross-section. I know there is not much to work with but would anyone know from what bone this section would be from? It is a long shot but ... it is worth a try. Best Regards Rob

Coprolite? found in Morrison formation near the Henry Mountains UT.

These teeth were found in Eastern Montana in Garfield County. I assume they are teeth but don’t know what kind. Would appreciate any info anyone could give on them.

Found in eastern Montana in Garfield County. Looks like a fossil to me but not sure. Any info would be appreciated.
