  1. With my last project wrapping up, this small skull was sitting on my desk and needs to get done. Way too much of my collection is in a half done state. Eumys is a cricetid, which includes modern voles, hamsters, mice and rats. When identifying one, the primary character I use is the shape of M1 and the fact it has no premolars. It's the only White River rodent I'm aware of with 3 teeth in the maxilla, most have 4 or 5 (I am prepared to be contradicted ) . M1 is very distinctive in that it has 5 cones. My plan is to remove the matrix from the side of the skull and expose the zygomatic (if its fully there). Will leave matrix in the orbits for stability. Then cut the base of the block below the occiptals and have the nose pointing in the air. I have been doing alot of pin and vice work to get it to this current state, I'll use a MicroJack-3 to get rid of the majority of the block. Not the greatest skull, and I have some better ones, but definitely something that you don't see every day.
  2. Lepticits

  3. Type of Oreodont

    Hi all. Please help me identify this Oreodont. Found in White River, Oligocene. Thank you
  4. I'm posting a current project in the hopes that it actually makes me finish it. I have a tendency to start several projects and set them aside for years. This Lepticitis was found in Wyoming in the late 90's. The initial prep was done by someone else (unknown) before the specimen made it to my collection. I've spent the last 5-6 hours under a scope removing glue, I would have almost surmised it was dipped in penetrant. It appears to have some abrasion damage as well, see the dorsal view of the skull above the orbits. I also took the opportunity to clean out foramen and do other various cleaning with pins and needles to get it to the state it is in now. Wish I'd though to get a pic before I started. Thanks to @jpc, I have some excellent photos of another Leptictis to base reconstruction off of. I'll post some more photos as the work progresses.
  5. Oligocene insectivore

    The garage was a bit chilly to work in today so I decide to work in the office at my scope a bit instead. I'd like to be able to identify this piece (Peratherium, Centetodon?) but I'm struggling with all the post cranial elements covering the teeth. Any suggestions from the perpetrator community for how to proceed?
  6. Hi, I've seen several sellers who labeled their Oreodont fossils as Leptauchenia. So I wondered are they the same thing or two different animals altogether? Thanks.
  7. Been working on a guy for over a year to get some white river material. He came right through Helena on his way to another fossil local in Canada. You cant see anything in this photo but some rather large jackets. Got a very nice disarticulated oreodont skull and a very nice rhino skull with other bones too. I also got a smaller jacket and now cant even remember what it is? This getting forgetful is a pain in the rear but at least I wasn't cooking? Ha! The oreodont is probably going to Australia and havent decided yet what to do with the other two projects? Ive really gotten/aquired/bought/traded for a heck of alot of fossil projects this year!!! To say the least!!! Im also just about broke! Still haven't finished my other White River projects from last year and I will also be getting a truckload of Fox Hills material in just over a week! Life is good. Or im a horder? RB
  8. An exploded stylemys tortoise

    So I've lurked on the forum for some time and decided to post my project. This is a stylemys tortoise that I've had since high school. It was really never worth recovering, being incomplete and completely disarticulated due to weathering. It was also somewhat crushed with only the plastron being in decent shape. Despite the challenge, I've decided to push onward, because it's got sentimental value at this point. The plastron was pretty easy to assemble: I have about 75% of the carapace (comprising the vertebral and costal scutes) but I only have about 50% of the edge (marginal scutes). This was the really painful part. Everything visible here was re-assembled from small disarticulated pieces: Here's some more carapace and all the leftover bits: My original hope was that I'd have enough to re-assemble the entire shell as one piece, without having to fill the holes. However it's clear that I don't really have a complete shell, nor is the bone strong enough to support itself without filling the gaps. In particular I'm missing most of the bridge connecting the carapace to the plastron. The plan now is to use epoxy to fill in the missing shell where necessary. I am undecided as to what extent I will try to color match the restoration (versus leaving it a different color to identify the restoration). Steve
  9. I'm restoring a titanothere cervical vert and process, and I want to be accurate. Can anyone suggest a research site? The sites I've found have the articulated spinal columns , which don't have the detail I need. I need at least a front and rear view. Thanks! Barb
  10. I finally got around to working on some Oreodont stuff. Last year I stopped by a friends house and bought a bunch of White River material. (my friend is going to stop by this May and bring me a bunch more). I did some work on some Oreodont stuff 20 some years ago and figured it would be fun to work on some more. I will call this skull #1. I realized at once that some of the skull was missing. Not good. I had already opened up this one and took off a bunch of loose rock and then decided to take a photo. You can see the earthquake crack in the rock and this thing was litterally falling apart all over the place. In this picture ive removed all the materail on the right of the crack including upper and lower jaw pieces. I was quite nervous but it was also fun and exciting. At this point ive use up almost an intire 2 oz bottle of super glue to hold the top part of this all together and when I turned it over, very carefully, lots of rock just came off with no prodding or nothing. The good thing was that the upper part held together and you can easily see the lower part of the lower jaws. At this point it was time for a wiskey. Here I glued back on the missing lower teeth. This thing was so fractured and falling apart the nothing really fit like it was supposed to but did the best that i could. Those extra two pieces on the left hand side also need to be glued back together and then both glued back onto the skull. Ok, bottom pieces glued back on and now set aside to cure. Tomorrow is gunna be a fun day. RB
  11. On my wife and my epic fossil trip this fall we spent a day in Nebraska in the White River badlands. Found some of the normal stuff...nothing spectacular but neat for us as we had this as a "bucket list" locality. One of our best finds was an oreodont skull. I found the nose at the bottom of a gully, and worked my way up until I found the outline of the broken bone. I dug out a volleyball-size chunk of rock and brought it home. Just finished prepping it out. It needs some reconstruction of areas around the snout that were weathered away, but all in all I am pleased with how it came out. At camp with a little rough prep to see what we had. Top view while at camp. Packed it away at this point. Underside after reattaching the muzzle.
  12. Hello forum preppers....need some advice. I started what I thought would be a very easy prep on a partial turtle I found in Nebraska this past fall. It was in 2 halves about 5 feet apart on a slope. Clean, glue together. Easy peasy. But....when I started cleaning I found that at least part of Mr. Turtle is still at home in the shell. So....I'm trying to figure the best approach. I'm thinking that I may remove the plastron as it is not all there, put it together and use it as a removable "lid" and then prep out the inside of the shell some. Problem with that is that it would lead to displaying the turtle upside down with the best looking part on the bottom. Also, can anyone ID the species at this point? Ideas appreciated!
  13. White river: How hard?

    Hello all I don't have much prep experience, and since I have very bad eyes I have trouble with microscopes to prepare fossils. I would like to learn how to work with my airscribe tought. So I want to prep fairly large fossils I can do without microscope. I have some stuff from France and Belgium I found myself, but or these don't need prep, or I don't dare to because I don't want to destroy my rare self-found fossils. So I came across the fairly common white river stuff. I found a website where I can buy unprepped oreodont bones and skulls. But what do you to prep these? Are they possible for total newbies when it comes to prepping? Is the matrix fairly loose or is it very stiky? I have an air scribe but don't know how to use glue. I've tried trilobites before but those are too tiny. I'm looking forward to your advise.
  14. Odd Mammal Tooth

    This was the first tooth I found on the day I spent on the white river formation in eastern Wyoming this past summer. I found a number of other small teeth and jaw sections from Leptomeryx, and small oreodonts along with what I believe to be a piece of canid jaw. However the identity of this tooth's owner has eluded me thus far. Any input would be appreciated.
  15. White River Astragalus

    I found this little astragalus with PaleoProspectors in Wyoming in late July of this past summer. It was found during the day spent on a ranch with White River Formation Oligocene exposures. I was wondering what animal it belonged to. Leptomeryx? Poebrotherium? some sort of oreodont?
  16. These toe bones were found in association with a ton of fragments. Quite a puzzle! Any idea from these tiny hooves what I might be working on?
  17. Just got back from our (my youngest son and self) trip yesterday. It was a buying and hunting trip with me doing most of the buying and he doing most of the hunting. Right now Im in a bad way and feel as if I been beaten up! along with all the shocks I have everyday and having a hard time walking, but the thing is,,,, Im all smiles. It was an all day drive to get into South Dakota and our first stop was a guy who sells White River fossils. After loading up some BIG Tortoise's and lots of the oreodont stuff, my son also bought some just for practice, we then went and found a campground. Had some wiskey, good food and good times around the campfire. Very cold that night. Got up early and took off to stop number 2. We arrived at our 2nd stop about noon and made small talk for a short while and then took off to the middle of nowheresville. Very bumpy road for miles. Thats what really beat me up. But then we arrived at our destination. a little small creek but cuts right through some Fox Hills formation. I did make it down to some rocks and I did find a few small ammos and then had to sit and rest but the son took off and headed for a big cut bank and Tom was over a ridge at another site. Once we realized it was getting late, we went and picked up my son, he had found about 4 big packs worth of ammo material. It was all wrapped up so I could not see any of it. I still have not seen most of what was found. He just kept telling me, " your gunna like this stuff dad". We then went and picked Tom, he also had 2 heavy packs worth of ammo material. Went back to my freinds house, had some wiskey, traded stories and such, had a cheese burger fest and went to bed, (back of my truck). Very cold that night. The next day we went back to that little creek and my son and Tom finished up the last two cut banks and we headed off to one more cut bank. I made it down to this cut bank, found a couple of really nice rocks and then had to rest. It was always cold! and yet, my son was in the middle of the creek pulling out concretions, throwing them onto the bank and whacking them open. Most were junk, but some were SUPER NICE! Made it back to camp, (my freinds house), and was invited for dinner. A beautiful roast, mashed tatos and gravy, home made rolls, peas, corn and green beans and polished off with some homemade chocolate cake! Wow!!! I slept good that night, but again, it was very cold. once we loaded up all the rock into my little trailer, I then realized just how my material we had. I had no get up and go left in my truck! but i was all smiles on the trip home. Most of the ammo material we brought home i have not seen so its really gunna feel like christmas once I get started on this stuff. Oh, but I do have one rock for sure that I found that I think is going to be worthy of 'Fossil of The Month'. Woooooooop!!! Wooooooooop!!! RB
  18. My wife and I found these small jaw fragments in W. Nebraska earlier this month. Not sure of the ID's. Each is about 3 cm long. Help is appreciated! Jaw 1 Jaw 2 Jaw 3 Jaw 4 Jaw 5
  19. 2 ID posts in 1 day?

    1. Partial mammal tooth? (Peace River FL, Mio, Plio or Pleisto). Maybe a piece of horse. 2. Another partial mammal tooth (potentially odontocete? also Peace River FL). 3. Yet another piece of Mammal tooth (Peace River).
  20. Tortoise Display Stand

    After prepping the big Stylemys that I recovered in Nebraska this summer, it seemed a shame to have spent all that time on the plastron only to have it sitting on a shelf out of view. So today I welded together a stand for it. I wanted the part upon which the tortoise rests to have as small a footprint as possible, because my idea was to use a mirror or mirrors to make the plastron visible to observers. Of course the angle of the mirror will depend on the height of the shelf where the tortoise is displayed. At just below eye level, this set up works reasonably well. If positioned below eye-level, this set-up works well (showing even more of the plastron).
  21. White River Mammal skull

    Hi Everyone, I wondered if you could help me confirm the species of the following skull I’ve just prepped. It’s a skull and forelimb found near Lusk, Wyoming in the White River Formation. I think this is a nice example of a Mesohippus but wanted confirmation if possible. Thanks in advance.
  22. Nice little Stylemys

    Finally getting to work on some of the fossils we got on our last trip to Wyoming! After some pretty simple wash jobs we decided to start on a little Stylemys we found the first night. We think we got most of him, some of the shell was washing out but we caught it pretty early and picked up most all the frags we could see. There's a pretty stark shift in color between the exposed shell (white) and the dark purple of the shell we uncovered. Pretty quick job of getting it out, but apparently I packed it up before the consolidant had really set
  23. White River Colodon?

    Hey all! Getting to work cataloging our finds from a very productive trip to Wyoming. Me and our friends can't quite figure this one out, our closest guess is Colodon. We aren't entirely sure though, and there's not too much reference material for Colodon. Collected on a ranch north of Lance Creek Wyoming in the White River formation.
  24. OK...the wife and I are starting to plan an epic fossil hunting trip for next year (our 30th anniversary). We've wanted to hunt the White River near Chadron, Nebraska forever. Now's the time. I have no connections to property, so I'm looking to the collective knowledge of the Forum. I know property is pretty sealed up vs. how it was in the 90's. We're willing to pay (within reason) for access. Anyone have suggestions?
  25. South Dakota Map

    (Posted in SD forum as well, feel free to move) I thought this would be an appropriate addition- my hope is that this map will allow forum users to plan trips to SD! Threw this thing together for you guys in some spare time at work. The map shows the extent of common fossil bearing strata in the state of South Dakota, as well as some "no-go" areas- reservations and the like. If you guys want a certain area zoomed in on let me know! FossilsSD.pdf
