  1. True or fake? And what species is it? I have this rare fish from the US Eocene. It has color and a lacquer applied. The rock is authentic and I have passed a flame over the fish and it does not melt, it is not resin. But I still have doubts.
  2. Knightia or Diplomystus?

    I bought this prepare your own fossil fish either knightia or diplomystus so I could prepare something for the first time which is why it looks like this don’t judge. I was wondering two things actually, one is it a knightia or diplo? And two are all green river fish this hard? I know I didn’t do a good prep job but was the fish poorly preserved as well? It was paper thin in some places and the fish doesn’t look whole it looks like its bones got moved after it died. Oh it’s also about 3 inches from the mouth to the “end” of the tail
  3. Hello all, I have been long searching for an exceptionally high/museum quality aspiration example from Green River. I recently have found myself with the opportunity to acquire this specimen. I've been told that there is a small amount of restoration on the tail of the Priscacara but I don't know exactly how much/what it entails yet. I'd ideally prefer a specimen with 0% restoration but I don't know how realistic that is. For scale, the diplo is 18" long, I'm told. It's obviously pretty cool that this is a Priscacara aspiration as my understanding is that this is pretty uncommon. I'd be very curious to hear your feedback on this piece in general, your thoughts on the restoration, and to hear your suggestions on whether or not this is the "right" piece to add to my collection (last part is a personal decision, I know...). I don't mind waiting to find the perfect piece... but I also don't know how realistic it is to find one much better as this one seems pretty nice to my eye. I wish the tail were poking out a bit farther but hey I guess I give the diplo credit for getting it that far down before expiring... Really appreciate your thoughts.
  4. I still have about 30 more to finish preparing, but so far, here are the best two I have prepped from my 2019 Green River run:
  5. Belated 2019 Road Trip Fossils

    Last year, to celebrate finishing my undergraduate degree, my girlfriend and I went on a long (9,000+ mile) road trip around the western US and at long last (a little over a year since their discovery) the last of the fossils we found are out of the refrigerator and I’ve finally gotten all of them photographed. Here are some of the highlights and best fossils we found. A rough map of the route of the trip While the trip wasn’t entirely fossil centric we wanted to hunt at a few cool spots along the way. We chose to visit 5 fossil locations, the first of which was Clarkia Fossil Bowl in Idaho, a fantastic location for Miocene age leaves (Langhian Stage, ~15Mya) tucked behind a motocross track. These poor fossils have been through it all in the year between when they were found and when I finally got them dry. They’ve been soaked several times, gone mouldy twice, frozen at least once and flown across the Atlantic Ocean, all before spending the last 8 months in the refrigerator. Amazingly all but two of them survived perfectly including one of my favourite finds, a tiny flower. A maple leaf (genus Acer) still partly covered in matrix but with the stem intact. At some point I hope to get this one prepared. The best leaf find of the trip, with beautiful red coloration and mottling from fungus. A partial leaf, with beautiful vein preservation. The next spot was the American Fossil quarry in Kemmerer Wyoming to look for Eocene fish (Green River Formation, Ypresian Stage, ~53-48Mya). Splitting though the material left out by the quarry we found a few fish, primarily Knightia and Diplomystus. The best Knightia, including the best fish of the day with its head still partly covered. Some of the Diplomystus. The first needs some repair as it broke through the tail. The second has a counterpart as well and I’m hoping to frame it soon. And a mystery fish, I don’t know what species this is, it could just be Knightia or Diplomystus but it doesn’t look like the others we found. The star find came close to the end of the time at the quarry, a section of a puddle layer packed full of Knightia, at least a dozen fish piled on top of each other. The quarry manager was kind enough to let me take the blocks without splitting them thinner since the material is full of fractures and likely would not have survived. The layer as it split in the quarry (US size 13 hiking boot acting as a rough scale). The three pieces I managed to recover. The blocks are currently in a storage unit in Washington until I can figure out how to get them prepared. I am hoping the first two pieces can be reunited and the part and counterpart can be mounted side by side but I’m unsure about how to accomplish this. If anyone who prepares Green River fish has any ideas please let me know. The third locality we visited was Westgard pass in Inyo California, hunting for Cambrian archaeocyathids (Poleta Formation, Cambrian Stage 3, ~ 520Mya). We were only there a short time as there was a lot of driving to do that day, but I still managed to find one example in cross section. My girlfriend was more lucky, finding four examples. These are our favourites, particularly the third, which exhibits some dimensionality in addition to the cross-section. I’m absolutely thrilled to find anything Cambrian, and to make things even better the fossil locality is just down the road from the Ancient Bristlecone Pine Forest, home to living trees more than 4,000 years old and one of my favourite spots on the whole trip. We also visited Capitola Beach to search for rolled cetacean bone. I found two examples with one clearly showing the cancellous internal bone texture. To cap off the trip I wanted to do a fossil hunt in my home state of Washington. Since I still don’t know where to go to look for the elusive Pulalius crab, we decided to search the West Twin River site for shrimp concretions (Pysht Fomration, Oligocene, ~22-33Mya). We found over a dozen of these containing partial shrimp. I think they are all Callianopsis clallamensis since this is a common species at this locality. The first concretion that I found after identifying the right material. Another shrimp nodule containing a large section of claw. The head of a shrimp. Two non-crustaceans, a gastropod internal mould and a beautiful white bivalve in a small concretion. A mystery concretion with something eroding out from both ends. And last, one of the strangest concretions I have ever seen. The outside is hardened but the inside is a soft clay consistency with several bits of shrimp shell, completely the opposite of the hard in the middle concretions I’m used to. In all, it was a fantastic trip. I would love to go back to all the sites we visited, and there is so much more to explore next time I’m stateside. I’m looking forward to getting out hunting again. Stay tuned for the next big trip to celebrate finishing our masters. Benton
  6. Leaf Fossils

    I purchased these 2 fossils a few years back at a show in California. I am trying to identify them......Thanks, Augie
  7. Green River Fish ID

    Here is a large partial fish I found a few weeks ago. Not sure, but suspecting maybe Phareodus?? Any thoughts? Thanks, Mike
  8. Diplomystus prep

    Hi all, I recently acquired this large Diplomystus fish from holdinghistory, not cleaned any of this materiel before so it’s been a bit of a steep learning curve, still lots to do but Im enjoying cleaning this. Thanks for looking Regards Neil.
  9. My wife and I went on a 7500+ mile ramble to break out of our COVID doldrums. Due to the virus we had to change up many of our original plans... which conversely added a number of additional fossil hunting locals as they allowed us to mostly avoid our fellow humans and maintain social distancing by many many miles. As part of our trip preparations my wife sewed us a number of masks, including a whole series of fossil hunting masks for me. Originally we were supposed to stay in Chicago, but we elected to avoid staying in the city, so we only got to do a drive by We started the trip with a bonus dig, meeting up with fellow forum member @minnbuckeye for a guided Ordovician hunt in Fennimore, Wisconsin (THANKS MIKE!) Unfortunately I neglected to take pics of the site so I will only be able to share a farm pic we passed on the way. Mike was a gracious host who kicked off the visit with a gift of several fossil samples from his home turf As with all of the fossils from this trip, all finds are as they arrived back home, no prep. Some of our finds from Fennimore:
  10. Feather?

    Hi, I’m considering buying this, and was wondering if this is a feather, it’s not listed as a feather but I’m curious if it is.
  11. Hell Creek to Green River trip

    My son and I just got home last night from a 2 week fossil hunting trip. We loaded up the trailer and made our way up north to the Hell Creek formation in South Dakota. This was the 11th year since we started digging with Walter Stein of PaleoAdventures. We spent 4 days in the field at his Tooth Draw quarry. This started out pretty slow for us, with an Edmontosaurus neural arch with processes but was missing the centrum. My son found an unknown plate. Highly fractured but it looks to have 3 original sides. The underside is still encased in matrix so we wont know more until its prepped out while might take a while. The finds got better in last 2 days. We found a few big BOBs, lots of Trike spitter teeth, and then a nice limb bone, possibly from a crocodile. The last day gave up a wonderful complete Thescelosaurus vert with all processes. It may not be clear in the pic, but its all there in the matrix. Then came a Nanotyrannus tooth, a partial mammal jaw, a possible piece of turtle plastrom and a final tooth with could be nano or could be raptor. It will have to be cleaned to examine it better for a good ID. Sorry, I dont have a field pic of that one. The weather didnt get better though. Our last day it in the mid 90s, zero clouds and 40mph winds funneling down the draw and sandblasting us all day long. But with great finds, you couldnt pry us out of there.
  12. Green River fish ID

    I found this a couple of summers ago at the American Quarry in Kemmerer. Just cleaned it up. It doesn’t look exactly like a Knightia. Might it be something else?
  13. Hello Everyone, Newbie here from the Emerald Isle. I finally pulled the trigger and purchased my first fossil—a Green River Diplomystus dentatus with Knightia eocaena. The seller is well-known and highly regarded on this forum so I’m not necessarily concerned with the authenticity, but I am really keen to hear people’s opinions on this specimen. My apologies if this is the wrong place to post. Thanks, Robert
  14. Went up to Douglas Pass, Colorado today for a hike with my wife. I have always hunted for fossils at the Radar Dome location. Today we decided to scout around for another location to collect. Hiked up a very steep hill to a shale exposure and found this larvae after only 1 minute of looking. We had not come prepared today to collect anything. Will probably head back up next weekend. The larvae is approx 2.25 cm across. There are also some parts of other larvae on the piece.
  15. Green River fish - what do we have here?

    I got this fish with some others in a trade deal the other day; I was supposed to get a mixed box of Diplomystus and Knightia, but this guy stood out for me. Doesn't look like either, and seems a bit too big for Amphiplaga. Maybe juvenile Mioplosus? Anybody? Is there another photo that can help? Thanks for looking!
  16. Fish paintings

    I'm working on some new fossil fish paintings and thought I'd share them here. I'm trying to work my way through the Green River formation fish first, though I'm sure I won't paint them all. I've only done two so far, but I'll add more as I paint them. The quality will vary, I'm sure. Here's my take on a Priscacara. and of course a Knightia: I've started on a diplomystus, and will post that soon. Thanks for looking. Oh, for those interested, I'm using gouache paints, similar to watercolor but more opaque.
  17. Fossil fish wall

    Since I have had more time to get stuff done due to Corona virus downtime I finally put together a fossil fish wall. I collected the specimens a few years ago in Wyoming. Thought I would share
  18. Is it paint or natural?Priscacara liops Green River Formation?thanks
  19. Green River Split layer Nymph?

    Final got to a Green River fossil that once exposed looks very much like a insect body or insect nymph. Would anybody out there be able to point me in the right direction as to what it actually is?

  21. fish are freakin hard to prep!

    I am always eager to try new things and develop or expand my skills. I've been putting in a lot of hours doing final prep on Hell Creek bone, and frankly, thats easy compared to these fish! I recently bought some un-prepped green river slabs from Ptychodus04. Since the weather and pandemic have put a halt to most things I began trying my hand at prepping these. Such a difference from working big dino bones! The fish bones are like fossilized hairs and unbelievably fragile. The matrix (on most of these) is extremely soft which makes clearing easy with a scribe, but also easy to blow it out. Using a soda blaster is a little more gentle, but still easy to blow out the fossil as soon as the matrix is gone. The bone details are so fine, I can understand how having a stereo microscope (along with a micro-jack scribe) would make this type of prep a lot easier. I think I did OK on my first fish. I'm scared to try and clear the spine any more because the bones are so thin and fragile. Then the second fish is in a harder matrix (and deep), but from what I've cleared so far, it seems to be a in a lot better condition. I'm afraid I may wear out my scribe exposing it though, LOL.
  22. Knightia - both?

    Good evening folks. I have two fish, both listed as Knightia and both from Farson Wyoming. They look similar but they don't look like the same species to me, am I wrong? These are 10 and 11 year old purchases with the first being dug in the 60's from "near Farson" and the second stating it is from the Green River Formation, Farson.
  23. Green River Fish Amia Head???

    Hello everyone, I'm looking for a second opinion on this piece, a fish head from the green river fauna, while I believe it maybe Amia due to comparisons I'm not to confident, any help/guidance is and will be appreciated.
  24. Fossil Fish ID Help

    The seller labels this as a diplomystus from green river but I don't think it is. The fins look wrong to me. What do you guys think?
  25. Hiodon falcatus?

    I found this Green River fish at the American Fossil quarry about 4 years ago. I think it could be a Hiodon falcatus, thoughts? Thanks for the help!
