  1. What are the characteristics of a White River turtle shell that can differentiate between Stylemys and Gopherus (Testudo)?
  2. I was looking closely yesterday at my tortoise (Stylemys nebrascensis from the Oligocene Brule Formation) that I found on my sons’ M&M Ranch in Nebraska that finally made it to my home in Virginia this Saturday. You can check out the two below links which describe finding it and the four year time-frame to get it home to Virginia: http://www.thefossilforum.com/index.php?/topic/65393-oligocene-tortoise-from-the-mm-ranch-in-crawford-nebraska/& http://www.thefossilforum.com/index.php?/topic/98983-my-stylemys-nebrascensis-tortoise-from-the-oligocene-brule-formation-of-nebraska/ I could see a number of rounded holes on the carapace. I started to measure the distance between the centers of the holes and determined that there were four pairs of holes with 45mm spacing between centers of three sets of holes and 44mm spacing between centers of the fourth pair. I don’t think that this could be coincidence so I believe that the holes may be puncture marks from the canines of a predator/scavenger. Below are pictures of two sets of holes: Do TFF members think that these are puncture marks from a predator/scavenger? If so, what animal or animals could have made them? I looked at skulls found on my Virginia property from extant mammals like skunks, possums, raccoons, coyotes etc. Most were under 23mm canine spacing. The coyote skull had the largest canine spacing at 40mm. So if the marks on the carapace of my tortoise are from a predator/scavenger it was a decent sized animal. My sons have the skulls of a good number of the predators/scavengers from that Oligocene time period. I’ll have them check the canine spacing. They have 6 or 7 saber cat skulls and I’ll have them check the saber spacing also. Marco Sr.
  3. Tuesday on the White River

    Hello everyone! know I've been slacking on updates on my three week trip to Wyoming with PaleoProspectors, but I promise I will post some more of my finds and do a full recap of last week's adventure as soon as I can. As for tonight, I'll share my experience hunting in the white river formation today, A view of where I began my day hunting. My first find: A section of Paleolagus (rabbit) jaw. Next I found a native american artifact After entering a larger area of exposures I came across this Mesohippus (horse) jaw.
  4. Hi everyone, I've been hesitant to post this fossil on here for a while as I didn't know if I wanted to hear a response which would contradict what I had hoped this would be. However, I recognize that to maintain a reliable and accurate collection I would have to properly identify what I found. The fossil in question is a possible partial egg that I found last year in the White River formation of Wyoming (Late Eocene/Early Oligocene) w/PaleoProspectors. This formation is known to produce fossil bird and reptile eggs (in fact, someone found a large, complete egg on this ranch the week before I was out there) so I knew that there was a possibility. When I found it most of the inside still contained sediment, which I have since gently scraped away to the best of my abilities. It has an odd dent in the top and no obvious pores, but the overall shape and the apparent shell make me think this is an egg. It is 8 mm tall and about 10 mm in diameter. I want to know what you all think. I would especially like to hear the opinions of @CBchiefski @jpc @MarcoSr @Auspex@Troodon Interior of the egg before I cleaned out the matrix. After I scraped away the matrix. Here's two views of the top.
  5. Just for fun A few micros from Kobrow, Germany, U.Oligocene.
  6. Hi there, guys. So, I got these from an internet auction. It's the first time I put my hands on this kind of piece. It doesn't "feel" fake or nothing, but I just want to be sure, so I thought I'd better get an expert opinion. What do you think? It's supposed to be Merycoidodon culbertsoni, from the Oligocene of South Dakota Badlands.
  7. Paleolagus

  8. Finally getting around to working on a jigsaw puzzle I found in the White River Fm of Nebraska a couple of years ago. Pretty sure it’s a soft shelled turtle, but I’m not having luck finding anything like it online. The shell is eggshell thin and seems like it was leathery in life. There are a few bones included. Suggestions?
  9. ParkerPaleo's White River Prep

    Now that hockey season has ended and the lab is warm again, and perhaps due to my new found extra time in isolation, I am embarking on documenting my prep projects. I thought I would start the prep season off with something easy that should turn out fairly nice. Please welcome my new little friendly Oreodont, Miniochoerus gracilis. It came into my collection in the summer of 2013 and has sat jacketed in a box until today. This evening I concentrated primarily on consolidation and bulk matrix removal with an ARO, and still have a ways to go. The plan is to prepare the "down" side in the hopes of a beautiful orbit and zygomatic arch. I did notice a cross section of vertebrae on the rear of the block so there is probably some neck attached as well. I'm hoping there is enough matrix below the jaws to make a nice pedestal to sit on as well.
  10. While playing with my poo (the fossilized version), I noticed this imprint. It is adjacent to a bone fragment. I'm assuming it is the imprint of a piece that broke away from the bone inclusion. It looks a bit unusual/ornamental, but I am hoping it is recognizable to one of you brilliant bone folks. This is from the Oligocene, Brule Formation, South Dakota. @Carl
  11. Unidentified vertebra

    A friend of mine sent me some photos of a really strange bone, and I believe it is a part of a vertebra. It was found on a dredge island across the river from the Wando shipping terminal in Mt. Pleasant, S.C. I collected at the terminal for a couple of years so I know that the only fossil formations found there are the Ashley formation (late Oligocene marine exposure) and some unknown late Pleistocene formation. The processes on this vertebra (if it is a vertebra) are really strange. The primary mammals from the Ashley formation are cetaceans and dugongs, but this does not look like it belongs to either one. There are also some large fish, like billfish and sawfishes. Does anyone have any idea?
  12. Another White River Skull For ID

    This is another skull in my collection that look very similar to the other that I posted. I believe this might be another Hyaenodon. Please have a look and let me know what you think.
  13. White River Bear Dog Skull?

    I have had this interesting skull for many years and was hoping someone might be able to narrow down what it is. I do not have any collection information as the person who found it is deceased. I know it is from the White River/ Brule formation. My best guess is some type of Beardog Daphoneus? Any help would be appreciated.
  14. I have had a bunch of broken bits of Oligocene mammal coprolites sitting in a cup for years. I got them before I had a proper microscope. I decided to pick through another one last night. This one had what I thought could be a rodent incisor. So I started excavating with my X-acto blade. As I uncovered the bone, I realized it was not a tooth. I started noticing these very fine crescent shaped objects (which I unfortunately did not photograph). So I decided to give the poo a little vinegar bath overnight. As I lightly removed an unremarkable bit of fossilized fecal mass this morning, it split away revealing what might be a feather. I wet a bit of downy feather and photographed it for comparison. What do you all think? @Carl, didn't you have a coprolite with a feather inclusion? If so, did it look like this? The bone that I exposed is very furrowed and hollow. Of course this may not mean anything other than it is partially digested. Could it be a bird bone? @Auspex Here is the before and after photo of the coprolite fragment. Here is a magnified image of the a wet modern feather and the possible undigested feather.
  15. Since I couldn't go out to dig for fossils, I decided to go on a micro dig. Today's dig was in a coprolite fragment from the Oligocene. Prior to excavation, the broken face of the coprolite looked like this. You can see a little bit of bone peeking through. After about an hour of excavation under 40X magnification, I uncovered what I think is a rodent tooth and possibly a toe bone and claw??? What do you think? Does anyone out there know their Rupelian rodents? Grinding Surface of the tooth: Side view showing roots: Small toe bone and claw or an fractured toe/foot bone? Is fossil poop cool or what???
  16. Trying to confirm id of two jaw fragments. From an old family collection. Label: Oligocene - White River, Nebraska, Sioux County, USA Both noted as Poebrotherium (tiny extinct camel) First three photos are the first fragment. Based on the large canine tooth and size of the other teeth, I'm thinking it might actually be an oreodont? Last four are the second fragment. Smaller teeth and wider jaw. Maybe labeled correctly as poebrotherium?
  17. What are these shark teeth?

    These Oligocene shark teeth from Temse (Boom formation, Rupelian, Oligocene) were classified as Odontaspis robusta, but I'm not so sure about it, as some of them lack cusplets. Could they be Isurolamna/some kind of Isurus?
  18. Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA
  19. Shark teeth

    Found washed up on beach in Isle of Palms SC outside of Charleston. Are they Megalodon or White and what Epoch are they from
  20. Coral?

    I believe we have identified this coral as Dendrophyllia elegans, you be the judge. The photos below are my specimen and the link below them contains a justifiably potential candidate. Many thanks to the TFF members who participated in this ID quest - especially Pippa! I cannot get the link process correct, so the last photo is from the Oxford University Museum of Natural History in the Lyell Collection. It is listed as "Oligocene fossil coral, Dendrophyllia elegans, from the Lyell Collection".
  21. Coral?

    Having found this in my unidentified drawer and without the documentation as to the species. Help?
