    Douglas Pass Mystery

    I have another Douglas Pass mystery. I kept all the pieces that I could find not knowing what it was. I am really confused as this does not look like plant material to me. It almost looks scaly like a fish or lizard, but I can't really identify any parts that would lead me in any direction that would really suggest that . Interested in any info or speculation. Thanks Oh. And this as about 6" long

    Utah Ammonite Help

    I found what appears to be a small (1 cm) ammonite in Green River, Utah back in 1993. Anyone have any idea what genus it is? I don't know the geologic horizon I found it in but looking at a geologic map of the San Rafael desert, it's probably Cretaceous. I do remember it's from the East bank of the Green River, near the Old Highway Elgin Road. Matrix appears to be limestone if that helps (reacts vigorously to acid). Thanks for the help.

    Green River Fish contents

    I had the time of my life at Seth's Quarry this summer. Everyone should experience what the Green river formation is like. Here is a 8 inch fish that I am curious about. Look at the enlarged picture of it's abdomen. I have white dots on the structures to be identified. My guess is intestinal contents, but maybe release of coprolites as the fish died, or I am even considering eggs???? Eggs are a long shot but it doesn't hurt to ask!!
  4. As above. I am considering getting a Green River fossil. The slab is much bigger than the fossil, so I intend to cut it down. However, the seller declined to cut it, saying it was a thin slab, and he feared cracking into the actual fossil. Has anyone here done prep work on GR fossils? Can I use a hand saw, knives, or scissors to cut down thin-slab Green River fossils? Or are there other methods you would recommend?

    Framing a Green River Fish

    We are back home now after being evacuated for a week because of the wildfires around Santa Rosa. Before we were evacuated I had started working on a Christmas gift for a friend who likes my fossils but is not a dedicated collector. In searching through my collection, I found a Knightia eocaena fossil fish I had dug from the Split Fish Layer near Kemmerer, Wyoming. It’s not the greatest specimen, but since I had both the part and counterpart I thought it might be interesting to put them together into a single frame. I thought I would fill you in on what I did. Original fis
  6. WhodamanHD


    Found this for sale, green river fish that has been placed in plaster for some odd reason. It looks to me two have two knightia and a large fish that is headless. It was not identified in the listing, it looks like a cockerellites or priscacara to me but I know nothing about these fish (if it is what I think it is its way underpriced so I'll buy it). Also, is there any restoration apart from the wierd plaster around it?
  7. I was fortunate to be the winning bidder on a rolling auction lot of two Knightia eocaena, one prepped and one unprepped, generously offered by @FossilDudeCO to benefit this awesome forum. It took me awhile, but I finally finished the prepping of the unprepped fish, and I wanted to share it here. These rolling auctions are nearly always great bargains, and the best part is they all help to keep the lights on here at TFF. Here's a link to the original posting for these Knightia. Here's how it began: And here's the result of my novice efforts (this was my second attempt
  8. I have been blessed this summer to have some amazing finds up in Green River. A couple of them come in the form of strange pathologies on a common fish. The Priscacara (or Cockerellites as it is now known) Is quite a common fish to find in multiple layers of the Green River Formation. The Cockerellites is closely related to modern perch, and is a highly prized fish due to it's unique appearance! I know there was a paper recently written (I believe in 2010) by John Whitlock, but I cannot seem to find it on any open access sites. Part of his debate for a
  9. Before I post my items for identification, let me first thank Seth for allowing me to scrounge around in his fossil pit in Kemmerer, Wyoming. The experience was unbelievable and it must go on everyone's bucket list of places to visit. I was absolutely impressed with the operation as a whole, wonderful staff, easy ability to prep your finds at the quarry, and most important, excellent and abundant fossils. As I finish prepping my fish finds, I will produce a more involved topic in the "TRIP" category. But for now, any help with these items would be appreciated: 1. I was told this

    Auction Prep Part Deux

    I'm almost caught up on prep jobs (3 going concurrently now) so I figured it's time to start in @RJB's monster fish. Here's how it arrived at my humble abode... Wow, what a fish!!!!! It rests in a 1" thick slab of 18" layer matrix (read hard as concrete) and Ron was nice enough to mount it to a 1/2" cement board... I think I got a hernia lifting it to the prep table. Needless to say, it is rather stable. Now for the prep...
  11. So I have this small block of Green River matrix that has fish material. When I got it, A part has been prepped, exposing most of it, but then I checked the corners, saw more covered material, and realized that it could be prepped even further. The problem is, I don't have any prepping tools because I've never prepped a fossil before But maybe is there any household tools that could efficiently prep Green River matrix? I just need to remove one tiny layer.

    Green River insect ID

    Newby at fossil forum.(or any other forum).Have been collecting fossils and minerals for years.Amateur/recreational,not too techy.but learning.Recently,Aug 2017 i was surface collecting wood and amber in the Green River Formation Area in Wyoming.USA.Examined a 4 inch x 3 inch piece of palm wood.(pictured).Found a visibly clear what appears to be a Damselfly,it has a reddish color tail and a black body,can also see a white colored tube on it.(feeding?).Also another insect in the piece is reddish colored which i cannot identify.And also another inclusion in the resin also pictured with the squig

    Palm Prep

    The last piece from the big @abctriplets prep job is their palm inflorescence. Man, this thing is cool. It is split into 2 plates that will be mounted together in a wall mount of some kind. Still gotta figure that one out. But, first things first... the prep. The inflorescence itself isn't much more than a stain on the matrix. So, I have to carefully uncover what I can without removing the stain! Holy snarge!!! There's a partial Knightia on top and a scrap of fin below (by the famous @aerogrower photocube). 3 hours later and there's an almost whole f

    Green River Fish Prep

    I'm working on some Green River stuff for @abctriplets that they collected on their fossil extravaganza! Thus fish is turning out to be a real gem. This is how the piece arrived in Texas. EDIT: 1st two photos courtesy of Jared. I applied copious amounts of Paleobond to both surfaces and clamped them together for several days, marking the location and direction of the fish so I don't forget. Then I went on the attack. The fish layer was about 3/4" below the surface so I used a small chisel and knocked about 1/2" off the top of the
  15. Im sure Ive shown this one before, but it was a long time ago. The funny thing is, when I first brought this little slab of rock to my prep bench, I automatically figured it was a Knightia! ha!! I always start on the head when I start prepping a fish and it didnt take long to realize that this was a Phareodus. What a super nice surprize that was! Came out quite nice but it does have a fin problem on the top side. Still, quite a nice little fish of 6 and 1/2 inches! Its now in the display case. Woooooooop!!! Wooooop!! With enough time this little case will be full? RB

    Big Fish

    Here is a rather large fish ive been working on for the last 15 years!!! Bout time I finish it up so I can hang it onto the wall. Ive still got to sand some edges so it will fit into the frame Ive already built for it. Then put a 1/2 inch ply backing on it and then,,,,,,, by gooly,,,, it will be ready to hang. I found some old wood on a very delapitated building along side the road one day, so its like that barnwood that everyone likes. plus it looks old too. The fish it old, so why not the wood too. I should have this done in a few days. Woooooop,,,Wooooop!!! I actually prep
  17. Three summers ago myself and my two younger sons were digging in the bottom cap just below the 18 inch layer. We found dozens and dozens of fish! My middle son brought some pieces to camp for me too look at. We camp right there in the quarry. At first look I was not too impressed, but put all the pieces into a box to take home and look at later. I can now see that it may be a really good Phareodus? I cut off a couple of pieces to make it easier to glue onto a piece of cement board and then begin prep. there will be some areas of rock building and one area of rebuilding some actual fish

    Strange banding in Knightia eocaena slab

    I've been working through a number of Green River fish I caught from the split fish layer (now called the sandwich layer) at the Warfield Fossil Quarry about 10 years ago. They have been stored away and I'm just now cleaning them up for display. Here are two slabs that are the part and counterpart of a Knightia eocaena. I split it out at the quarry, brought both halves home, sawed them into two rectangular slabs, then wrapped them up individually in two sheets of bubble wrap and put them away for all those years. After pulling them out of storage today and running some water over them to w
  20. Here's a good question. I do have several big fossil fish from the Green River Formation and already have a good idea how to hang those big monsters, but what about the smaller fossil fishes on smaller slabs of rock that are not framed? There has to be a way? @FossilDudeCO Fish like these in the picture and a whole lot more. RB

    Green River - June 3-4, 2017

    On June 3rd and 4th I ditched my regular hunting grounds for the opportunity to meet up with a forum member @Seve78 at one of the Pay to Dig quarries in Kemmerer, Wyoming. Tom chose to spend Saturday at Warfield Quarry and Sunday with me at American Fossil (AKA Fish Dig) which is run by our very own TFF member @sseth Tom was an absolute pleasure to dig with and he filled his suitcase with literally tons of treasures to take home, I would meet up again in a heartbeat! I arrived at 9:30am on Saturday and spent about 4 hours helping to prep the site for Tom on Sunday. I
  23. My kids were purty darn young when we, as a family, started going places to hunt for fossils. Back then, about 20 some years ago, I found that one could go fossil fish hunting with a company called Uricks Quarrys. Not sure of the spelling. It cost $65 for 3 hours of digging. For me, back then, that was a heck of alot of money. They told me that you get 3 hours of digging, then back to their shop for cutting and squaring up the rock. Well, I got there one morning and off we were. There must have been 10 or 12 people there and after a short bit of what to do, we all got to work. Like mos

    Green River - May 15, 2017

    Made my first trip up to Wyoming to visit the fish quarry this weekend. Everything went well, but the rocks are still a bit wet. We spent most of the time removing junk to get to our good productive layers! The main mission of the trip was not to dig, but to see how the winter had treated us! Below is a picture of the quarry Our digging platform for the split fish is right behind that truck and trailer. We moved the trailer up this year to house our finds and our gear! Of course....being such a gorgeous day and only about 16°C or 17°C we coul
  25. I will be taking the family on our trip to Kemmerer the 2nd weekend of June. This is the trip sseth offered up to auction back in Nov/Dec. My 4th had to back out due to a family issue so I posted the open slot under the rolling auction if anyone is interested in joining us out there under sseth's guidance for 2 full days of eocene rock fishing the green river. I will also be hitting Big Cedar Ridge in WY for some cretaceous plant fossils on the 6th and U-dig in UT for some cambrian trilobites for a couple of hours on the 12th in case anyone's looking for digging company that week
