    Nimravid! But which one?

    Hi guys! Recently I got in a trade this nimravid mandible from the white river formation in Shannon County. Now I want to ask your help to determine the genus, if possible. Being incomplete and missing all the teeth it's quite difficult but it has a quite elongate mandible flange and by the number of the alveoli it had three teeth. I think it can be Hoplophoneus, what do you think about it?

    Salvinia sp.

    The Rott fossil Fossillagerstätte (Rott district of the town of Hennef) is a limnic deposit of Upper Oligocene fossils known in paleontology because of the richness and exceptionally good preservation of fossil plants and animals. Although the site was already designated as a natural monument in 1942, a golf course was built on the former mine site in 1986. Reference: Heinrich Winterscheid, Zlatko Kvaček, Jiří Váña, and Michael S.Ignatov (2018): Systematic-taxonomic revision of the flora from the late Oligocene Fossillagerstätte Rott near Bonn (Germany).

  3. I'll be honest, I've put off writing this trip report for far too long. Between work, school and general procrastination I have delayed this post for over 7 months. Perhaps there's a silver lining to me writing this in the middle of winter, it could act as a nice break from the grey & cold conditions many of us are facing this season. Hopefully you all enjoy a dose of warmth from a trip which I enjoyed greatly. Ok ready? Let's go. My morning started around 4:30, ungodly hours for me generally, but I woke up excited for what lay ahead. Less than a half hour later we were on our w

    Florida Gastropod Identification Help

    Hello, Please see the attached photos, I found this along the Withlacoochee River in Madison County, FL. Up the river from the limestone is Madison Blue Spring State Park located approximately ten miles east of Madison, FL. The limestone is from the Oligocene age Suwanee Limestone and I am interested in learning more about the spiral shaped gastropod in the center of the photo. There are other interesting shells in this specimen as well. Please see attached photos for reference. Thank you in advance! Greg Kruse Casper, WY

    Panopea (?) micro fossil.

    This specimen from the Oligocene Keasey formation is 5mm long. This shale is extremely hard, I had to use the 3 pound hammer to break it. The rock it was encased in was 8 x 9" and this was the only fossil I could find after breaking all in 1-3" pieces. Image is a Olympus Macro 60mm image on a Panasonic G9 camera using flash. Do you consider a fossil of this size a Micro fossil? I am going to leave it in the matrix because I've tried dental tools on this particular shale and it is just too hard. Need to do some further work on the ID with external shell features/geometr

    Mineral or Fossil?

    Hi all. Yesterday, I went on my first fossil hunt in about fourteen years. Went back to one of my old haunts, Jan Juc beach on the south coast of Victoria, Australia (Oligocene deposit - mostly mud and sandstone). I was expecting to find the usual - sea urchins, small crabs, coral, sponges etc. Instead I found a big, dark thing. A thing is all I can describe it as - buried in sandstone with the eroded top showing, I initially thought it could be a toe, or maybe some petrified wood. Once I moved the boulder to my garden and attacked it with a small hammer, what popped out was a little puzzlin

  9. This specimen was found in the Pittsburg Bluff formation (Oligocene) in loosely consolidate sandstone. Due to the large opening and smooth shell I believe it to be a Neverita. Although the location is near the town of Pittsberg Oregon, I can't recommend it for the faint of heart (you are about 4' from the traffic which is mostly log trucks going > 55 MPH). However that being said the talus at the bottom of this formation is a marine invertebrate hunters gold mine. There was one piece of the sandstone that was fairly large (over a meter long) and it and every stone beneath had fossils. Most

    Oligocene fossils ID

    .These fossils are from Romania. They look like crustaceans ichnofossils. If these Eocene or Oligocene fossils are really traces of crustaceans then what genus did make them? If you think that you can identify them write your opinion here. Thank you very much.
  13. Can anyone identify this 1ish inch shell that is agatized that dates back 23-24 million years ago found in Tampa Bay Florida? Does anyone know a paper that references these? I use muriatic acid to clean limestone chunks of agatized coral stick. Many times I come across other items like this. Corals and shells. Just trying to get a better idea of some of the items I found. This was left for me by mother nature on a storm Christmas eve 2020.

    Looting Lincoln Creek

    There was a fleeting glimpse of sunshine, so me and a few guys decided to hit the Lincoln Creek Formation today. We know a great spot by the Chehalis River, which also happens to be about 15 minutes away from my friend's house. Nothing better than a convenient site! The site would be inaccessible were it not for an abandoned old logging track that takes you over the water. We often compare it to that one scene in "Stand By Me".

    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

    White River Formation Help

    These are from Nebraska. Since it’s not oreodont, I’m lost. Do people find coprolite in this formation?

    White River Formation Carnivore Canine

    Hello! This is a canine tooth (that has been split in half) that I collected from the White River Formation (I believe Poleslide Member of the Brule) from Weld County, CO. I think it is a carnivore’s canine rather than simply an Oreodont canine just due to its size, but I could be wrong there I suppose. My best guess is Daphoeneus or similar due to its shape, it does not look like Hyaenodon to me, but again, could be totally off there. Pictured is the tooth’s lateral surface, interior (because it was split when I found it) and the “cutting surface.” Thanks!

    End of Year Hunt

    Rains started in ernest today, river hunts will probably be on hold until Spring. Hit another site yesterday in hopes of finding some cetacean goodies or anything worthy of packing out. Found a fish nodule, Aturia fragment with nice color, clams and enough glendonite to cover my neighbors driveway.

    Oligocene Canine Lower Jaws

    This June I went hunting the Oligocene White River formation in Wyoming and found two lower Canine jaws. I could us a little help in identifying them. I was thing the second one could be a bear dog. Its a juvenile with new eye teeth starting to erupt but the front of the jaw is missing.

    white river fossils

    Hi guys i have these brule fm jaws from sioux county, Nebraska and i was wondering if anyone could confirm if the Id's i have for them are correct, thanks 1.leptomeryx spp. would a species level be possible?
  23. I am looking for info on a turtle which I have heard called a "helmet turtle". Mine is truly shaped like a helmet--fat and rounded--does not look like a stelemys... ...found in SD. I once saw a similarly shaped one in NE, but it wasn't worth collecting. I just want--at this point--to know if such a thing exists. If I can get affirmative info, I'll send pix. Thank you.
