  1. Latest graphite studies of Green River fish. Preliminary sketches for later color illustrations. Quite a challenge getting scientific accuracy, but hopefully I'm improveing.
  2. Hey y'all! I'll be staying in Salt Lake City for two and a half weeks from Mid May to the end of May. I was hoping to see if any of y'all knew of any private tours/quarries that would be open during that time. I'm looking for fossil fish and trilobites mostly, so if anyone knows of any trilobites aside from U-Dig that would be appreciated too. I recall going on a private digs when I was younger that was not affiliated with any of the big names (with permission from the landowner of course) - hoping to find something similar. Calling all people that "know a guy" - thanks!
  3. This is a re-post of a topic I started late this last summer, but got lost during the August forum migration. Late in July I took a trip with a few friends out to the American Fossil Quarry and Fossil Butte National Monument to hunt for fossils out of the lower Eocene Green River Formation. The Green River Formation is a lagerstatte which is perhaps the best site in the world for articulated fossil fish, many of which also display varying degrees of soft tissue preservation. Fossils from this locality are mined commercially and are ubiquitous on the fossil market. Living in Denver, the Green River Formation is only a few hours away by car and I've always wanted to plan a trip out there to collect it, which is very easy to do and fairly cost-effective thanks to numerous pay-to-dig quarries where you get to keep essentially everything you find. I decided to plan a dig at American Fossil Quarry, which is one of the more popular quarries. I managed to convince two of my friends to come with me, and we spent a day and a half (12 hours total) at the quarry while camping at the nearby Lake Viva Naughton. It was my two friends' first times ever hunting for fossils, and they both report that their expectations were far exceeded at the quarry! There's a very good chance this trip was the start of the making of two new fossil fanatics. We had a blast out in the quarry, with the thrill of discovery doing plenty to stave off the oppressive sun and desiccating dust. We also made sure to visit some of the fossil shops located in Kemmerer and spent some time at the museum in the visitor's center of Fossil Butte National Monument, which is fantastically well put together and was so awesome to see. Each of us found plenty of treasures, including lots of Knightia and Diplomystus fish as well as coprolites (fish, stingray, and turtle), scales, occasional plant material, and even a few rarer fish. Here's some pictures from our adventure: Myself posing with a very nicely preserved Knightia eocena. My two friends hard at work splitting shale for ancient treasures. A few of my day one finds on my shelf. A very nice partial Priscacara found by one of my friends. A small stingray with associated Knightia found by a different participant the first day we were there. A mostly complete Amphiplaga brachyptera (one of the rarer fish) found by me, associated with a Knighta alta. Only the tail and part of the dorsal fin is missing, the rest of the fish is intact! Easily my prettiest fish: An absolutely perfect Diplomystus dentatus found by me the second day. One of the displays at the visitor's center of Fossil Butte National Monument. Cheers, and thanks for reading!

    A couple Green River Fm. Insects

    Hello, I am looking for confirmation and if possible specific identification of these two insects I have from the Eocene-aged Green River Fm. of Colorado. 1. Labeled as "Mosquito" 2. Labeled as "Mantis"
  5. DPS Ammonite


    I want to give this away with a correct ID. Is the a Knightia fish from the Green River Formation? Fish about 9 cm long. Thanks, John
  6. With my wife still out of town for a couple of weeks and the kids back in college, It somewhat frees up my routine of family life and I get to be spontaneous with my schedule. So a second road trip up from Salt Lake, UT to Kemmerer, Wy. A beautiful drive of 155 miles which supplies enough scenery to enjoy every mile. Red rock canyons, granite canyons, terrain change for high mountain desert to higher elevation, very treeless and windy with cooler temps. And definitely less crowded! The quarries are at 7300 feet above sea level which makes a bit of an affect on the human body coming from lower elevations, even my altitude of 4500' ASL. Upon arrival at a different quarry than my first excursion I felt ready to go at it. The crew gave me the orientation- the do's and dont's and set me free. And off I went into the splitting rows of rock. About 10 vehicles with solos or couples were already on site by 9:45am when I started my session. As expected, the common finds were knightia and diplomystus with a few mioplosus, cockerelites and priscacara found now and then among the fossil enthusiasts. I chose a 4 hour session so I got busy. Three hours into it I realized I wasn't needing a bathroom break and began to feel gassed out. Dehydration just kicked my backside. Stupid me. I took a break and started drinking and eating some fuel. I slowed down for the last hour but was still lagging. My storage rack was full and another pile beside the "harder" rock plies away from the easy stuff were ready to load. Both rock supplies were pretty much equally productive. One was just harder = big hammer, big chisel to get them started cleaving. The highlights of the trip: Being there!, seeing families and couples enjoying their adventures, meeting a capable, attentive manager & crew of the quarry, the squeals from the kids who found a fish!, talking with the other fossil hunters, and off course finding more than plenty of fish to take home. Oh, and two stingrays and a gar fish were found while I was there. Not by me ...but everyone celebrated. Especially, the second stingray found by a lady in her early 90's. She said she had waited 30 years to do this. The lowest points: time raced by which led to my bout with dehydration. One plate broke on the way one = fixable, but as you can guess right on the fish, and not taking many photos, I ate an apple, PB&J sandwich, two Capri Suns, a soda ( yeah, bad for dehydration, oh well ) and a Gatorade, Then stopped in town and bought Advil, another soda, ( bad Steve ) a Cranberry juice and felt the rehydration take effect. While in town I followed up with a recommendation by Kris -aka - Ptychodus04 to stop by In Stone Fossil shop. So glad I did. A total ball out of the park homerun. The proprietor was incredible and we hit it off. Especially as soon as I mentioned Kris from Texas. She lit up with enthusiasm and praises about him. And there on the wall was " The Bird"! WOW! is all I can say after having seen the prepping thread images here on the forum, there it was less than a foot away. Amazing prep work in every aspect of the bird. The hostess said let's get a picture of you with it. Okay...I was dirty and tired still recovering from the dehydration and nausea. Being in the shade and down almost 500' in altitude helped a lot. The Bird The Gar Kris prepped. Incredible presentation...I think he said he logged 107.5 hours on it.. And the Gar fish proper without the derelict old guy running on steam and adrenaline...lol The palm fronds were among my favorites in this candy store. Amazing! A table top. A massive 45 X 67 inch gorgeous Sabalites powellii, palm frond. And to top off the visit/tour of the fossil shop, the proprietor, out of the blue says. Let me show you something. Since you know who Kris is ( i clarified that our relationship is via an internet forum about fossils, not a face to face personal acquaintance). She said that's okay, follow me. Through a couple of doors and I'm in the prep room and there in front of me is the 13 foot crocodile on the table. Wow! this beast is insane! Looks ready to bite your head off, I mentioned that the bone is like milk and dark chocolate in color and she said we call it mahogany. It does look like the mahogany obsidian chunks I have in my rock garden...only in the shape of a prehistoric reptile. There were chomp marks on its mouth and scutes on its back. Something bigger and badder got ahold of it at some point. Probably a bigger croc or mating partner. croc. A view into the air abrasion box. Foreleg. And...the Gar fish and a stingray found at the quarry. Well that's a wrap on this part. I gotta get to the airport to pick up a daughter flying in from Nash-Vegas. All my finds are in the man cave and I'll start going through them soon enough and add a few pics of my finds. I have one more free weekend coming up....wonder what I should do for 3 days?...hmmm. Go hunt Ammonites, Trilobites or Green River fishies? Steve
  7. Here are some Before & After photos of the 2nd and 3rd fish at practiced prepping, and 1 coat of butvar. I sent 7 fossils off for professional prep and haVE about 35 full fish I'm going to do some art projects with and hang in a wooden frame. I used a razor blade, Q tip, and safety pin.

    Green River basin turtle

    I had went on a hike last year out in the badlands here in southwest Wyoming and stumbled across this turtle nestled up on a small peak. About a month ago, I took the same hike to retrieve what I had found ( horrible hike to pack a 50lb turtle on my back ha) and I was seeing if anybody might be able to tell me more about it by chance?
  9. Hello, My wife and I recently returned from the Green River Formation in SW Wyoming and have about 20 decent fish fossils. The limestone was wet from snow melt and is currently drying out on a table. My question is, what is the best medium to use to seal them forever? I have read about using Elmers-Glue All, Butvar and other resins, and clear lacquer. I read through some posts on this but they seemed more focused on cleaning/detailing the fossils which I have done as much as I am willing to risk already with an air blower and dental pick. Once they are dry, what is the best method to seal them completely with a clear finish so I can give some as gifts and not worry about how fragile they are?

    Diplomystus fin or gut contents?

    Hello, I've been prepping this Diplomystus dentatus from the green river formation and I noticed something odd seemingly "inside" the ribs. At first I thought it was an extension of the pectoral fin, but it looks quite different and seems to be on the other side of the ribs. Any idea what this could be? Some sort of gut contents? PS. The fish is about 5 inches long
  11. Hello, My wife and I found these in Wyoming, other than #1/#8 (Myoplosis) can someone help me identify the other fish? I plan to finish them when fully dry (the rock was damp from snow pack) and apply butvar and write the species and date on each one to give to some family and make a small display.

    Green River Fm. Insects?

    Hello, Can someone help ID the insects and other stuff on this plate? It's from the Eocene Green River Formation of Colorado, and the whole plate is about 12 cm long. I see some winged insects but have a hard time telling if they are crane flies or potential dragonflies/damselflies. Thanks.
  13. Hello friends, I am asking for help. What fish is it? Knightia eocaena? Gosiutichthys parvus?
  14. Locals work on 52-million-year-old crocodile fossil Kemmerer Gazette, Kemperer, Wyoming Yours, Paul H.
  15. Prehistoric Chili Pepper Fossils Challenge Tomato Plant's Evolutionary History, Study Says The open access paper is: Deanna, R., Martínez, C., Manchester, S., Wilf, P., Campos, A., Knapp, S., Chiarini, F.E., Barboza, G.E., Bernardello, G., Sauquet, H. and Dean, E., 2023. Fossil berries reveal global radiation of the nightshade family by the early Cenozoic. New Phytologist. Open access paper Yours, Paul H.
  16. Just recently added a really cool specimen to our Leeward Community College Natural History Exhibit. It is a Priscacarid from the GRF with 4 anal spines and 11 dorsal spines. The specimen is just shy of 8 inches and very well prepared. I have emailed Lance Grande, the author of "The Lost World of Fossil Lake" for his opinion on this specimen and is awaiting his reply. Has anyone seen or know of other specimens similar to this? Your feedback is greatly appreciated. Thank you very much.

    Recommendations on Prep

    Any recommendations on how to prep this? I am brand new to this world but was fortunate enough to discover what I believe to be a juvenile turtle, Chisternon Undatum, a few years ago at one of the commercial quarries on the Green River Formation in Wyoming.
  18. Hey all! I've taken a job in Lander for the summer, and am hoping to plan a few fossil hunting expeditions before I head back out east in the fall. Does anyone have any advice for fossil hunting out here on a budget, or any favorite locations? Thanks!
  19. This is actually quite enjoyable finding out which fossils are real and fake. First pic we have a fossil flower stamen from the Green River Formation in Utah. The second piece was quite cheap, but it's from Morocco (Anti-Atlas Mtns.) and it seemed odd to me that the bottom Orthoceras has the same pattern as the matrix below it. But perhaps you have an explanation for that. The third piece is a Ginkgo leaf from the Sentinel Butte Formation of North Dakota. The final piece is a Juvenile Megalodon tooth from Pungo River Formation of North Carolina. Thanks again to everyone who's helped out, I'm sure I'm not the only one who's learned something.
  20. Hi All, This past summer, my daughter and I went to a couple of sites in the Green River Formation to look for leaf and insect fossils. Here's a video we made about our trip and findings. We also visited the Field House of Natural History in Vernal and the curator took us on a tour of the collection. cheers, Lloyd

    Douglas Pass, Colorado Finds

    My partner and I visited Douglas Pass, Colorado last August: Eocene, Green River Formation, Parachute Member. The site represents a very shallow lake bed and is known primarily for fossil plants and insects. Recently I unwrapped her finds. The first one I think is some type of fossil seed. It is about a half inch long. The second, I think is a partial insect larvae, about an 8th of an inch. Let me know what you think. Thanks.

    Green River fish spawn

    From the album: Fossildude's Purchased/Gift Fossils

    Unknown fish spawn from Green River Formation. 8 mm in length. Found on a gift from Jeffrey P. @Jeffrey P

  25. I was given the fossil fish below. It didn't come with any details, but this looks like a Green River Formation fish, which means it could be from Colorado, Wyoming, or Utah, right? Any thoughts on genus and possibly species? Thanks!
