    Collected South of the Radar Dome near the cliff face.
  2. 52MYO Fossil Clock!

    Tick Tock, It's a fossil clock! I didn't know what section to post this in this looks as good as any! This clock is 100% natural! No inlaid fish here! And the numbers were a very unique find...clear evidence of alien visitations 52mya in modern day Wyoming. Now if I can just find the ship.... All jokes aside, let me know what you guys think! Sorry my picture is slightly fuzzy...I don't know why other than I am a TERRIBLE photographer!
  3. Green River Botanicals?

    I have a couple of interesting fossils collected in green river formation. The first is from just below 18" layer and I have been thinking it was a leave, but the form is odd with large dark center section and now I am wondering if it some type of seed or fruit? It is about 3/4" long. Any thoughts? The third photo is of a fossil collected from split fish quarry and it looks like a seed or nut to me (almost similar to a pistachio nut), but perhaps just my imagination and it is some collection of fish parts or other. It does like there is the start of another similar shape just to the right of this. It is about 3/8" long. Thought I would also add photo of an insect collected with the first fossil . It is a Plecia Pealei and just looks nice with the wing structure visible.
  4. Phareodus sp.

    Detail of skull and teeth of juvenile Phareodus specimen i collected at Carl Ulrich quarry back in the early '70s when he used to let visitors collect with him.
  5. Larvae.JPG

    From the album Green River Formation. Parachute Creek Member. Douglas Pass, Colorado

    Larvae from Parachute Creek Member of the Green River Formation. Douglas Pass, Colorado.
  6. Flower Green River Formation, Parachute Creek Member Douglas Pass, Colorado. Radar Dome area. Denver Museum of Nature and Science. When I first saw this flower, I walked right past it thinking it was a dead flower laying on the rock. I'm glad something in my head made me go back and take another look. I realized that this specimen was rare and asked the Denver Museum if they were interested in it. They were, and the donation was made.
  7. So I've been trying to do some research on the fossil flora/fauna of the Parachute Creek member of the Green River formation and so far I can only find the following reference mentioned as representing any kind of significant effort to catalogue the fossils: "The Eocene Green River flora of northwestern Colorado and northeastern Utah, HD MacGinitie - 1969 - University of California Press". The problem is, it is out of print and not even listed on the U of C Press site. I found a copy available from a book seller but I'm not sure if it's worth the money to buy it sight unseen. I already have plenty of other books like that already on my shelves. There is a database of sorts that the Denver Museum of Nature and Science has online, but I'll be darned if I can figure out how to work it. Any other suggestions?
  8. I flew in from Southern Florida, FossilDudeCO drove in from Colorado & we set our sights on the town of Kemmerer Wyoming. He'd been there before, I had not. He made arrangements for us to hunt a private quarry & we cracked some rocks! Here's our story in pictures. Following the quarry owner to his mine On top of the mountain finally able to see the quarry.
  9. Greetings! I found this the other day. They just don't look right to me. They're awfully dark, and seem to have eyes even. I'm not thinking of buying, just testing my judgement. Real of Fake? Unfortunately this is the only photo I have.
  10. Wyoming And Utah Fossil Trip

    Hey everyone, Long time no see, hope everyone has been doing well. I was hoping you guys might be able to give me some recommendations for a trip I'm planning next month. Right now my plan is to head to Kemmerer and look for some green river fish, and then head to salt lake city for a couple day. Next I was looking at going on to Delta to hit up U-dig for trilobites, and then heading to Moab before finally heading home to ND. So I guess my questions would be what quarry would you guys recommend in Kemmerer? Is U-dig worth it or is there a better quarry in that area to visit? Does anyone have any other recommendations on places to stop along any part of the trip for fossils or otherwise? And are there any special tools I should bring to any of these locations? Thanks again for your help everyone, I plan on posting all my finds here after the trip too.
  11. I had to share this one even though it is difficult to make out under layers of rock. It is my first Green River Crock, and the first ever crock from the Dempsy quarry area in Wyoming. It has a 2/3 complete, articulated skeleton and at minimum, complete lowers (I have also drawn in what we assume is the upper skull. The first picture shows the articulated skeleton and where the skull and lowers were before removing the lowers. The second picture shows a cross-section of one lower jaw. The skull is just over 3 feet long. This crock was found this weekend in the Fossil Lake section of the Green River Formation and dates back to the Eocene. The species has not been determined yet. This is probably my new favorite fossil find.
  12. Hi all, I wish to get a Green River flower or feather. The entire fossil, including matrix, shouldn't be larger than 3" by 3". I can trade you one of my fossils (I've got amber, iridescent ammonites, croc teeth, edmontosaurus teeth etc). Thank you.
  13. This is quite an odd find but I'm pretty sure it is a Knightia eocaena. The spine has a weird curve in it, which looks like a bite pattern...
  14. Green River Fish Prep

    After I have removed excess matrix from the fossil, what are my options for finalization of the prepping?

  16. Green River Fish Prep Kit

    Hello! I wanted to share and get advice on my preparation of a Green River fish fossil purchased in a kit. I have never done anything like this prep job before and I am hoping to learn on this piece so I can work on some nicer pieces. Here is the kit as it came in the mail: And here is the contents of the box. Most of it is fluff (a book mark, window sticker, some random fossils in a bag etc) and the tools are obviously the most basic available. The "multitool" is an acid brush with a nail hammered into the end and some material stuff in the handle to hold it in place. It also has a "limestone eraser" labeled "blick" and a small plastic magnifying glass. There is also a basic guide on how to prep the fish and a guide to the different fish fossils found in the Green River formation. Here is a view of the contents: And here is the actual fossil slab: The head is obviously on the left and the tail on the right. Some of the black markings look to actually be a marking put on the limestone to show the rough outline of the fish, although some of the black marks are the actual fossil peaking through. The slab is decent size, about 3 or 4 times the size of the typical cheapo gift shop green river fish. I am going to start on this a little today, probably work on the back third of the fossil first, working out from the backbone. I will post more pictures as I go. Wish me luck!
  17. Green River Fish Plate And Mystery Fossil

    Hello, I have a question that might only be able to be answered by speculation. I recently acquired a Green River, Wyoming fish plate (knightia) which is pictured below. It is an awesome piece and it seems like i'm always noticing something new. When I got it, i noticed there was a bulging area on the 'backside' of this plate that had been chipped away to reveal what looks like a fossil. The layer revealed is the same color as the knightia fish and has a unique texture. The bulge raises above its surroundings approximately 5-7mm and the overall diameter of the area is about 4-5 inches. Does anyone have any insight into what this might be? A flat, circular dome shaped fossil. The only thing that looks likely from what i see online is maybe the lateral portion of a stingray. A guy can hope right? What do you think? Any info or help would be appreciated. Thanks!
  18. The Wyoming State Geological Survey recently made public a link to Grande's out-of-print paper entitled "Paleontology of the Green River Formation with a Review of the Fish Fauna" Bulletin 63. Link is below: http://www.wsgs.uwyo...s/docs/B-63.pdf Thanks to the WSGS for making this paper available electronically!!!
