Cool Priscacarid from Green River Formation -- 4 anal spines and 11 dorsal spines
ahlung62 posted a topic in Member Collections
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.- 3 replies

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.

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!

Final Round of Real vs. Fake
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
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 -
Green River Formation Leaf and Insect Fossil Trip
Fossilized Dad posted a topic in Fossil Hunting Trips
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- 13 replies

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.

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!

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

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 an

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

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

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 f

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
