  1. Hi everyone, I have just purchased an Oreodont skull. I have no experience with these. I assume this is genuine, but I don't know much about what they are supposed to look like, so I'm just hoping for some expertise from people who know more than I do. This one seems to have a lot of matrix that needs to be removed, but I certainly wouldn't want to mess anything up with it being unskilled with that kind of work. It looks like at least part of the bottom jaw is still in the matrix, you can see a large bone sticking out in a couple of places. What do you guys think?

    Some White River Formation Fossils For ID

    Hello everyone! Earlier this year, in August, I went fossil hunting in the White River Formation. This jaw was one of the first specimens I found. Unfortunately when I found it, it was actually in better shape... When I found it it had obviously been out in the weather for quite some time, and so it was kind of fragile. I was not thinking, and just took it out of the ground, hoping I could put most of the pieces together later. I know it was a dumb decision, and I won't do it again (hopefully...). Along the way, I lost some parts, and so now it is not near as complete as it was.

    White River Prep - Rodent

    I was inspired by another WR post and thought I'd share what I was working on today. I had a small rock with a sliver of rostrum showing (white bone). Poked at it a bit with a microjack and it just kept going. All scope work so far. Was hoping for a cranium but no such luck. No nasals either. Now I'm trying to decide how it should display and how I was to expose the cheek teeth. Here it is sitting flat. And I'm thinking I will stand it on edge for display, like so. Will have to rem
  4. I have 2 white river mammal skulls that I am hoping some can assist with identifying. They both measure a little over 4 centimeters. one has been prepped out of the matrix preserving a relatively complete dentary (including the bases of both canines). The second is still covered in matrix. I am fairly certain that the one that is prepped is likely a rabbit.

    White River Skull Prep

    I recently got this skull as a fun prep project. I bought it as a Hyaenodon skull from North Western Nebraska. But I quickly noticed that it was likely something else. I don't have a whole lot of experience with carnivorans but I think it might be a nimravid based on the number and placement of the teeth. Hoplophoneus or Dinictis maybe? It's missing its fangs and all the front teeth but otherwise it's in general good shape. I've already removed a whole lot of material. And it's starting to look like something. There is very little crushing and the bone is quite well preserved. But

  11. Good evening to my fellow fossil lovers! This report has been on hold for a while, hovering near the top of my paleo-to do list. But to be honest, I haven't been on the forum as much these last few months and I've just sort of kicked the can down the road, pushing it off. Well here we are in August 2022 and I'm a whole year and some change removed from this excursion, but I say better late than never. With that out of the way lets jump into this adventure! I hope you're ready for... The Roadtrip Through Time: Colorado Part I: Pierre Shale In the winter of 2021 I ha
  12. Hi all! I love W.R and Oligocene fossils. Both prepping and looking at them. So i thought maybe its time to see what everyone else has collected out there. So let’s see pictures of what you’ve got! Heres a few of mine!

    Fossil hunting trip!

    Me and my family just finished up our first fossil hunt! We are still at the ranch, but are leaving in the morning. We all are sad to have to leave the ranch. We all had fun exploring and doing different thimgs, (though some of us a lot less than others) and really enjoyed talking with, Rick and, Jean. They are really nice people. And it is a really nice place to stay. Unfortunately the guide, and everyone else cancled, so we were fossil hunting alone. WE left home at 2 AM on saturday, and arrived in Omaha, NE around 11 AM. We stopped in Omaha to visit with some fa
  14. I received this little partially prepped oreodont skull from an old paleontologist I've connected with and I noticed these two spots on it. Are they just conveniently placed holes? Or are they a bite mark? And if so, from what?

    White River Carnivoran Jaw Section

    Hello again. I wanted to share this jaw section I found in Wyoming's White River back in July 2020. My initial thoughts were that it belonged to the primitive canid Hesperocyon, which in my experience has been the most abundant carnivore in those badlands, however, it doesn't quite match the other material I found which I'm confident is dog. While scrolling through the forum I saw some similarities to a jaw section labelled as Daphoenus by @Nimravis on the thread below: The fossil itself is 3 cm long and ~2 cm from the tip of the tooth to the base of the jaw. I'd be interested to see som

    Entelodont Incisor?

    Hi everyone! I wanted to get some opinions on this tooth I found in Wyoming's White River formation back in 2020. While I was initially unsure of what it could be, over the last few years I have been of the belief that it was a somewhat worn incisor from an entelodont (Archaeotherium mortoni). The deeply rooted tooth is ~4 cm long and ~1.5 cm at its widest point. Any input would be appreciated. @jpc @siteseer @ParkerPaleo

    Some Oreodont Bones

    I had recently received a couple unprepped oreodont limb bones from @snolly50 and have started prepping them. Here's a pic of my workstation There's been a lot of repair in these bones that I had to do. The bone on the left I'm pretty sure is a humerus. Here's some more pictures of that one Then there's this other bone that I'm working on repairing and prepping, I think this might be a femur? Then I have this piece that looks like the end of the tibia and fibula with some tarsals. And last I have this unidentified limb bone end, about 3 inches long

    White River fm. Mini Claw

    Hi everyone! I found this claw while anthill hunting on the White River formation of northeastern Colorado. It's about 6 mm in length and 4 mm tall. Honestly I'm not certain that it's a fossil, but if it is I'm really excited to have found it. My first guess is that it's a small bird, but it could very well be mammalian or reptilian. Any input is appreciated.
  19. 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 &

    White River Prep - Rodent

    I've been in the lab this fall/winter but preparation has taken a back seat to the plastics/replicas operations. As things start to wind down with plastics around this time of year, I'm embarking on my next prep project. This specimen is from the same Wyoming locality as the Herpetotherium I posted about recently but was found many years ago(~15?). It appears to just be an upper skull of a small rodent but there is some hope for lowers. I pulled this piece out of its field packaging in April but just now starting preparation in earnest. So far, all I've done is rough prep around the bound

    Coprolite lovers, Help!

    Serious, experienced replies, please! This 0.5 cm long object is attached to a broken coprolite from the Eocene/Oligocene of NW Nebraska. Trying hard to figure it out. Wrong twexture for a tooth and it doesn't look like a seed, either. I have a guess, but right now a guess is all I have. Any coprolite specialists out there? I know the pictures could be better, but I don't have a microscope out here in the field.

    White River Rhino Skull Prep

    Today I got this mostly complete Subhyracodon skull from the White River formation, South Dakota. Right now it still looks a bit rough since it's been crushed a bit and there's a bunch of sediment stuck all over the place. The specimen has been pretty well stabilised. So it's not very fragile thankfully enough. Almost all the teeth are present. Only one maxillary tooth is gone and the very tip of the premaxilla is gone. The 2 posterior premax teeth are still there, but the anterior ones are gone. Roughly half of the braincase is also missing on the back of the skull. Otherwise the skull is qui
  23. Hey guys, First, sorry I've been absent from the forums. After the death of @caldigger I just kinda fell off from the social aspect of it all. It's been a weird year and some change. Covid has effected us all in some form or other, the planet is basically on fire, and politics is eating us from the inside out. I've literally lost friend, figuratively and metaphorically from all of the above. In the time of my absence from the forums, I have been fossil hunting. I've only shared my experience with people that are personally close to me, mostly @Bone Daddy. But, I
  24. Hi folks- I have had a good time this past month after work, prepping some White River specimens. This first one is the smallest turtle I have ever found... it so cute! This one took me 8 hours to prep. This next one is now officialy one of the prides of my colletcion. Whe I collected it only the top of the skull and a few leg bones were visible. No field shot, but here it is before prep began. You can see the skull at the bottom of the block, and some leg bones just above my thumb and a few more to the left of the green and black marks. I took th
  25. I was recently out vacationing in Wyoming and spent Saturday morning (7/24/21) hunting in the badlands. As I sat down to rest for a moment, I looked down and saw what I thought were a radius/ulna pair from a small mammal. Upon closer inspection, it was a pair of lower jaws freshly exposed on the edge of a nodule and on the backside, a small skull. Needless to say, I was ecstatic. I spent a bit of time making sure the specimen was consolidated (Paleobond Penetrant, wish I had brought some 4417) and packed it up for the trip home. I was thinking it woul
