The Green River Formation is one of the most well-known fossil sites in the world, occupying present-day Colorado, Utah and Wyoming. This Lagerstätte has been noted for its well-preserved fish fossils, as well as numerous invertebrates, plants, and sometimes even reptiles and birds. Green River fossils are Eocene-aged, at 53.5 to 48.5 million years old. Thankfully, not only are Green River fossils attractive, they also remain affordable to the casual collector. Allow me to present my humble collection. Crocodile tooth Borealosuchus sp. Southwest Wyoming Water bird tracks (possibly sandpipers or plovers) Presbyorniformipes feduccii Vernal, Utah Bird feather Aves indet. Southwest Wyoming Crane flies & Mosquitoes Pronophlebia rediviva & Culex sp. Parachute Creek Member; Douglas Pass, Colorado

Earlier this month @JD3B and I went a incredible fossil hunting road trip. The title may be a bit misleading, as only one day was actually spent in the badlands. There were however, plenty of good times. We were lucky to have the opportunity to visit a few storied formations, and even luckier to have a couple tff legends to guide us. The first morning was an early one with a 3:00 am wake up. I was at Jacob's (JD3B) by 4:00 and on the road before 5:00. First stop, the Helena, Montana area to visit the world renowned @RJB museum of natural history. We arrived late in the afternoon and honestly, this place alone would have been well worth the long drive from western Washington. One of my few regrets from this trip was not getting any pictures of Ron's amazing collection. If you know where to look however, pictures can be found elsewhere on the forum. Ron, you could charge admission! After touring his prep lab and drooling over display case after display case, it was time for a couple frosty beverages. Over the course of a couple cold ones and a lot of laughs, we went from online acquaintances to friends. He was a gracious host who not only let us park our RV in his yard for the night, but gifted us with some beautiful fossil to remember our stay. The next morning we bid Ron a short lived farewell. We were to meet up again in few days to do a little "fishin". But in the mean time, we set our sights to SE Idaho to try our luck hunting trilobites. Here are my first fossils of the trip, acquired from the "gift shop" at the RJBMNH. Thanks again Ron, you're all right. I don't care what Jacob says about you.I didn't get specific IDs for these, but first one is bird tracks, second is sand dollars, then pectin and cockles.

Finished this fish yesterday, preservation wasn’t terrible. The head Isn’t preserved well and neither is the tips of the fins but anything is better than my first prep which was on an exploded knightia. Could of turned out better but I’m satisfied with it. I have a couple questions. 1. can you tell if it is a priscacara or a cockerellites? I believe they are two different genera with different species. 2. What is the part in front of the fish’s head? It’s not bone, it’s very thin and different, I have no idea what it is. Oh and I was prepping with a not so sharp needle thing, criticism and tips are welcome

Hello everybody, Asking about a certain fish fossil I received from a friend who found it at the Green River Formation. Under one of the fish, there is a sort of long, tapering, uh, feces-looking squiggle. (Trying to be mature here!) I want to know is it a fish coprolite, a mineral deposit, or something else? If I didn't know better I'd suspect it was the entrails of the fish. Anyone out there who can help? I've also attached some pics of other suspicious discolored spots that may help.

I recently purchased a Priscacara specimen with what appears to be four anal spines. In his book "The Lost World of Fossil Lake", Lance Grande mentioned that there is a possible new species with four anal spines and an elongate body. I am including a couple of photos and would like feedback as to whether this is truly a Priscacara with four anal spines; and if so, what is the status of this being describe as a new species or just a mutation. Your comments and feedback will be greatly appreciated. Thank you for your time.

I found this tooth while prepping some of my fossils from the American Fossil quarry near Kemmerer, WY. This is actually in the same plate as a partial stingray that I've been trying to piece back together! I didn't even know the tooth was there until today, weeks after our trip to the quarry! It is very hard, shiny, and completely 3-dimensional. Has some ridges running longitudinally from the base (visible in picture), but these fade out and the top half is very smooth. No serrations. 1cm long, 2-3mm wide. Some quick googling makes me think Crocodile Tooth - there is a picture on FossilsForSale.com that is pretty much identical, and is listed as a crocodile.

Looking for some assistance and guidance. I have spent countless hours reading posts about fossil preparation and specifically about fish prep. The knowledge shared here is humbling to say the least. So here goes: If your end goal is to be able to do all the things necessary for 18" layer Green River material, split fish Green River material, Hell Creek material; how big of a compressor should I start thinking is overkill? The smallest capacity I've considered is 20 gallons, the largest 80. I'm just wondering what people are using in terms of capacity and if I'm better off going bigger for future growth of my needs, or for example a 27 gallon is all that I would ever need running 1 tool at a time. I very much appreciate any input!

I got two unprepared GRF fossil fish, a Knightia and a Priscacara as presents for my birthday, in a kit that also contained a small handheld needle-like tool. I would like to get some advice from the experienced members of this forum on how to proceed. For tools, I have a sewing needle, x-acto knife (with parental permission,) and the tool that came with the kit. I have a slides microscope that can focus well enough for a prep in order to have some magnification. I have Lance Grande's book on the GRF for anatomy, and have read all of the prep threads I could find on this forum. I have decided to start on the most exposed part of the backbone, and move up from there, saving the delicate fins for last. I have already tried out the tools on a few coprolites and vertebra on the rock. What advice do you have for this prep to be as successful as possible? @RJB @Ptychodus04 ? Thanks!

16cm long, looks like some kind of Nightia nut I am not sure.

What do you guys think of these four knightia fish?
RepoMan9130 posted a topic in General Fossil Discussion
I am new to fossil collecting and paleontology in general. I wasn't sure if these are real, as it's almost unbelievable to me that I can buy such things for so cheap, but apparently the seller is highly regarded. I was under the impression that finding multiple things fossilized together is quite rare? Either way, I impulse bought this, along with some spinosaur teeth. What do you guys think? These knightia are from the Green River Formation in Wyoming, and according to the site, the largest fish is 3.1 inches. Any thoughts, impressions, or random information would be appreciated.

Looking for recommendations on 1 air tool to buy for softish shales and limestone
mattbsharks posted a topic in Fossil Preparation
I am looking to spend around $250-350 total on an air compressor and one air tool well equipped to prep both green river formation limestone and softish shales like penn Dixie/dsr. I understand that no one tool would be perfect for that, but I want to find one that can do both jobs solidly. -
I just returned from 4 days of digging in the Green River Formation. The quarry we dug in has 18”, mini fish, and upper gastropod layers currently exposed. Coming from Texas, we anticipated cooler temps but it was downright cold. High temps in the 40s and 50s with lows as cold as 30F! We had 1 day that was an almost total rain out but we dug 3 days and 2 nights on the 18” layer. We dug every day in the mini fish layer and randomly picked up pieces from the Upper Gastropod layer. On the second to last night, we went to bed in pouring rain and awoke at 3:00 AM to the tent collapsed on us due to heavy, wet snow! Everyone started pushing the snow off and the tent popped back up. Needless to say, we didn’t sleep much that night because we were now soaking wet and had to keep knocking snow off the tent. That was rather exciting g for Texans in July! Here’s our own little corner of the world. This pad of 18” layer produced some really nice fish, leaves, and a feather. Digging at night was a great experience, even though it was COLD!!!!! All in, we had a great time and I have piles of fish to prep now! More to come as I get specimens sorted and prepped. This was the view from the quarry after we finished digging on the last night of our trip around 1:30 AM.

Ammonites, Trilobites, Fossil Fish: Another Western Adventure
Jeffrey P posted a topic in Fossil Hunting Trips
Barely a month had gone by since my last trip to New Mexico and Colorado, but I already had plans for this trip in the works. Primary focus this time, which was a solo trip, was fossil collecting, visiting well known sites that have been on my radar for quite some time. I flew out to Salt Lake City and drove directly to Kemmerer, WY. My first stop there was Fossil Butte National Monument: Here is a view of the visitors center (free admission) and the surrounding barren, but awesome landscape that surrounds it:

I found what looks to be a large fish scale, but I’m not entirely certain. I would like some help with potentially ID’ing the species. I tried searching online, but nothing I found looked like what I collected. This was collected from the split fish layer of the Green River Formation at American Fossil Quarry in Kemmerer, Wyoming. It is about 1.5cm in length and width. Thanks for any help.

Hi there! Now that Christmas and New Year's are done, I'm trying to continue organizing and labeling my fossils before I head back to work on Monday. I'm hoping I can get some help from you regarding the identities of 2 specimens: Specimen #1: a brachiopod from the Miocene (Burdigalian) of Sesimbra, Portugal: Specimen #2: two fish from the Eocene Green River Formation of Kemmerer, Wyoming: (fish on the left:) (fish on the right:) Thanks in advance for your help!

I just acquired a GRF fish plate with a Knightia, two Diplomystus, and an interesting ventrally compressed (?) fish. Any help with identifying this fish would be greatly appreciated. Thanks in advance.
