    Amphiplaga brachyptera COPE, 1877 Middle Eocene Kemmerer Wyoming USA Length 8cm
  2. This report is long overdue, but I thought might be worth posting based on the response to the rolling auction items currently up for bid... In the early summer of 2017 my family and I set out on a 7000+ mile roadtrip through 21 states. The trip gave me the opportunity to collect at a couple of famous sites like the Kemmerer's green river formation and wheeler shale in Utah, but one stop combined fossil collecting with some of the most beautiful countryside I've had the opportunity to experience. Big Cedar Ridge is a late cretaceous deposit near Worland, WY. The plant fossils are plentiful but delicate in a light gray matrix, I say "in" rather than "on" because the fossils were the result of a large ash fall that buried the foliage where it stood so the fossils are often in 3 dimensions rather than simply found on horizontal planes. To say it's off the beaten path is an understatement, but it's well worth the effort. Make sure you pay attention to the weather, pack appropriately and make sure your spare tire is in good repair... just in case. We started out early from a bed and breakfast at the base of Devil's Tower (thanks to @minnbuckeye's recommendation). After a 3+ hour drive we got to a spot where I thought the road should be a little past Ten Sleep, but there were no road markers to be found. We went a little further before turning around and taking the unmarked dirt road we initially passed. We didn't see another car once we made the turn so make sure you have everything you need. The drive is 15 miles of dirt roads through BLM cattle grazing land.
  3. Hey, I am finally completing my dream-job at the American fish dig quarry!!! I am just looking for some advice from you Greenriver veterans! Any helpful tips, like what I should bring, what I should do, and where the best place too eat is when it is all over!
  4. Visiting Devils Tower Area

    The grown-up family and I are heading out to Rapid City/ Belle Forche for some Hell Creek goodies and making a side trip to Devil's Tower. Going to be free July 7 and 8. Was even meeting if anyone wanted to meet up to hunt in the area or recommends a good spot. Happy to bring some east coast fossils with us.
  5. I have a 1in long Notogoneus fry from the 18in layer of the Greenriver formation. For reference of the rarity of this specimen, https://www.nps.gov/fobu/learn/nature/fossil-fish.htm I am looking to trade this fish for more fish specifically Mioplosus but, I am open to all fish offers. I will also consider dinosaur material from Kem Kem or Hell Creek. Also sorry for the bluriness of the photos, I will get better pictures up ASAP.
  6. I am headed to Kemmerer with my son to look for fossils. I am aware of the quarries in Kemmerer and want to know if there is anything that we should not miss on our road trip or around the area. We have 5 days to explore. Thank you!
  7. Tooth or just a rock

    Found this odd rock , initially thought someone painted on it but the blue grey color appears to be natural , Found in wyoming along the road waking to the post office
  8. Teeth ID

    I was sorting through my collection from decades ago. I have these teeth from the Lance Cr formation. I always assumed they were Triceratops but haven't found any confirmation. They don't match the photos on the internet. So I thought I would ask the experts.
  9. skin impression on the dino bone?

    The dino bone was purchased in Wyoming. Is it the skin impression on the bone surface? Thanks!
  10. Jurassic Ripple Marks??

    I have had these and others in my collection for about 27 years, most of them have been wrapped up or still are wrapped up since I collected them with my son. I always classified them as Ripple Marks, but wonder if they are, we collected them a little to the West of Sundance, Wyoming in exposure that is supposed to be from the Upper Jurassic / Morrison Formation. What is your opinion?? Top of Plate Bottom of Plate
  11. Lance Fm. IDs

    Hey all, I found these over the summer in Wyoming's lance formation (Maastrichtian, upper cretaceous). I was hoping for some input on these specimens. First I believe is a small champsosaur vert, the front has a piece chipped off, but it measures 7 mm front to back and about 11 mm wide. Second I'm not so sure on, it's vaguely shaped like a coprolite which would be nice and would make it the second I found on this trip. It seems like it may be geologic. It measures 3.5 cm from top to bottom and has a diameter of about 1 cm.
  12. This spring break (March 17th-23rd) my girlfriend and I are planning a trip in Utah, Wyoming, and Colorado. It looks like most of the big dig sites are closed for the season, which was a disappointment for us to see. The tentative plan was to go through Kemmerer from Salt Lake (home,) and hit the digs sites there, go through Vernal to the Quarry and the Prehistoric Museum there, then to Dinosaur National Monument in Colorado with a possibility of hitting Price Utah and the Cleveland Lloyd Quarry on the way back. Without any of the digs open, it seems like we're just trying to find simple things to kill our time, but we'd rather be out doing more engaging fossil hunting or learning. Does anyone have recommendations for areas somewhere nearby where our travels will take us? Any suggestions for digs, museums, cool fossil shops, or even just pretty places to camp are all welcome and greatly appreciated!
  13. What’s this fish?

    A freebie to me. Common I’m sure, but what is it? From Parachute Creek I think. Yes, committed the cardinal sin, no scale. It’s around 8cm. @Fossildude19
  14. Hey everyone! Even though we are well into 2019 I thought I should share my top ten finds of the year. These will not be ranked as each one has their own value to me although some are rarer than others. Let me know if you want a better view of any of the fossils. 1. Bird Talon (Hawk or other raptor), Peace River, Florida.

  18. This small 'insect' was purchased from a thought-to-be trusted seller at a shop close to where I live. I have been a little sceptical and was wondering what an expert's opinion may tell me. Is it a fabrication? Is it real, just badly preserved?
  19. Worn Nano tooth?

    I got this worn theropod tooth a little while ago. It's labeled as Nanotyrannus from the Lance Formation, Weston County, Wyoming. However, it looks a bit odd compared to other Nano teeth I've seen. Is it a tip from a larger tooth? Can it even be identified when this worn? Have at it Scale is in centimeters
  20. I'm trading a bunch of fossils mainly from Utah and Wyoming but some other locations as well. In return I'm looking for theropod teeth, ammonites, trilobites, crabs, gastropods, and more shark teeth or anything else that's interesting. You can reply here directly or PM me. I'll post another set some time later this week. Here is the assortment. Wyoming Knightia (Green River Formation, Eocene) Assortment of brachiopods, a crinoid holdfast in the middle, and pyritized worm burrows from Paulding Co, Ohio (Silica Shale, Devonian) Fossilized Great White tooth from Cape Town Another Great White: Knightia Elrathia kingii (Wheeler Shale Utah, Cambrian) The following Wyoming Knightia (Green River Formation, Eocene) Some are in better condition. There's a couple that haven't been completely prepared. I know some of you like to prepare your own fossils: Elrathia kingii More Paulding Ohio fossils (horned corals and brachiopods): A Phareodus scale: Another Great White: A St. Mary's formation Chesapecten conglomerate from Calvert Cliffs, MD:
  21. Sorry for the long wait for this post. I said I was going to do a write up for it in the days following my return, then once again in October and then after I had finished my trip report from my 2016 trip to Maryland's Potomac River back in December, but alas I never got to it. But now I'm finally sitting down to write about my experience from my week spent fossil hunting in Wyoming's badlands. I flew out of Boston in the morning of July 13th and landed in Denver by around mid-day. My parents got the rental car and we were on our way to eastern Wyoming. It was dinner time when we pulled into Laramie and we went to a Mexican Restaurant which had great food but gargantuan portions, we made our way back to the Comfort Inn we were staying at and soon got a grasp of how low quality it was. Sockets coming out of walls, old hairs on the bed, the scent of cigarette smoke permeating throughout the room, not quite as comfortable as advertised. The next day we left the motel in haste and went to the University of Wyoming's geologic museum, which had a number of great displays of fossils of which many were found within the state. Here are few shots of what we saw.
  22. Barosaurus prep

    These past few months I've been working on the weekends as part of a team of amateur and professional paleontologists to prepare a large Barosaurus at the Museum of Ancient Life in Lehi, UT. From October to January I have worked on two large vertebrae from this adult Barosaurus. I believe we won't know the gender until we begin work on the pelvis but not to many of these species have been uncovered so we'll have to compare some other models. It's been a very rewarding journey so far. Here's a couple of pictures of preparation work with a Paleo Tool Air Scribe (forgot the model but one of the larger ones) in October. I'll try to get some before and after photos as we're making tremendous progress on these vertebrae. Behind me is a large 9-ton jacket containing a group of Utahraptors and an herbivore (sand pit). I'm not allowed to post any photos of that but the sickle claws and raptor teeth are a very impressive sight. FYI I realize this isn't as finite or fragile a work as the prep jobs @Malcolmt or @Ptychodus04 do but hey it's a start. Working on the vertebrae's. A near complete vertebrae is on the bottom right. I now wear a mask since the matrix particles are so fine and can get into your lungs and eyes. On the wall above me is a skeletal layout of an adult Barosaurus. The red filled in portions indicate the bones we've already recovered. The pelvis, back femurs, feet, and an assortment of vertebrae. The head is yet to be found and might not be in this jacket. Up close of the vertebrae. Another angle Another angle with some near complete tail sets behind me. If you look closely you'll see some completed vertebrae in the background. Another angle Working from behind the glass so viewers can come see. This is a rewarding, volunteer based opportunity where I feel like I can give back to the community. Occasionally I'll poke my head out to educate those passing by. The youngsters really like this exhibit. Smiling for the camera. Fossil description is on the bottom left. The nine ton sleeve containing the Utahraptors is directly behind me. Another angle This might be my favorite. It shows most of the vertebrae lined up. This photo was taken back in October and I'm amazed at how far it's already come along. Really excited to post some closer photos and will compile a time lapse. A bit fuzzy but another angle Another angle Another angle Another angle (yes I'm wearing my Penn Dixie fleece FYI @DevonianDigger)
  23. Lance formation matrix fun

    I had picked up a box full of Lance formation matrix bits a little while ago. This evening while in the garage I couldn't fight the urge to poke around a bit at a couple of pieces. I probably should only focus at one at a time....but temptation. I didn't really mess will the champsosaurus vertibrea in the matrix. I broke out the dental picks and started to play with these chunks. I didn't stay out there long because it doesn't have heat but there are some interesting things that are exposed. Hopefully I can get a spot in the basement set up so I can get deeper into this. I don't know I this fits better in the fossil hunting section or the fossil preparation section.
  24. Salamander Vertebra

    From the album Lance fm. Microsite Finds

    cf. Scapherpeton tectum Late Cretaceous (Maastrichtian~ 66 mya) Lance formation
  25. Croc Jaw w/Unerupted Tooth

    From the album Lance fm. Microsite Finds

    After cleaning some of the excess dirt off the fossil I found that it had a tooth still unerupted. One of the cooler fossils I found on this trip. Late Cretaceous (Maastrichtian~ 66 mya) Lance formation
