Just finished up this 2nd Priscacara prep job from 18" layer. I'm noticing each fish is its own beast, some are in softer stuff and some harder. Did this one between 20 and 30 psi. I keep getting fish that seem to have damage to the tail before they are buried. Also picked up a 12v electromagnet on Amazon. Works great for collecting the iron powder. Click it on, collect, click it off.

Trying to locate Green River unprepared Priscacaras for newbie prep practice.
kmmerwick posted a topic in Fossil Preparation
Hi all- Would anyone be able to advise on where I might get unprepared Priscacara (tails at least) fossils for practice. Thanks so much for your help. K -
This is a Cockerellites I found last year and had prepped out. It came out in a pretty gnarly split and had to be glued back together and prepped. With slight restoration it turned out very well. Looking closely at the anal fin spines, you'll notice the pathology, this specimen has 4 instead of the usual 3. This is most likely a pathology of a Cockerellites liops instead of a new species.

Selling Real for Fake Fossils?
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
Everyone I've encountered on this site has been very helpful, so thank you. However, I'm in need of more help. For the last year I've been collecting real fossils in the field and selling some to pay for more exotic rocks. In a recent post I found that my Solnhofen shrimp is, if not totally, mostly fake. Now I'm quite suspicious of my entire purchased collection and was hoping you could help me identify fakes. The first two pictures are apparently Priscacara, Green River Formation, Eocene; the next two supposedly Asteroidea, Morocco, Ordovician; the last three supposedly Triassic, Arizona petr- 25 replies

Well, I’m finally getting to dig into my truckload of fossils from my Wyoming trip with @RJB so it’s my turn to open up a prep thread. I spent a couple hours today poking around to find the perfect fish to start with. The 18” layer never disappoints. This good sized Diplomystus has 2 Knightia on top of it. I’m going to try to save both but I’m concerned that the right hand one is covering most of the Diplo’s skull. If that’s the case, the little guy will have to go! This is after about 90 minutes of scribe work.

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 watercol

Cockerellites I prepped roughly a month ago
KompsFossilsNMinerals posted a topic in Fossil Preparation
This is a Cockerellites I prepped about a month ago. I used a dremel lightly to get the top layer of matrix off, then used a regular pick for the finer preparation. For my second Cockerellites prep ever, I think I did a pretty good job. The coolest part of this piece is that there is a long piece of coprolite(?) ontop of its head. I have no clue if this would bring up the value, I kind of doubt it would though. -
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

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.

Hey everybody! I realized I never made a thread for my internship at the Field Museum in Chicago this summer. I interned as a fossil preparator under Akiko Shinya in the McDonald’s Fossil Preparation Laboratory (that’s the “fish bowl” lab on the second floor right next to Evolving Planet with the big window). There were some amazing things being prepared in the lab - an Antarctic Lystrosaurus, lots of Dicynodonts, Green River fish (some massive Phareodus), Sauropod femurs and ribs, a massive slab containing several sturgeon and paddlefish - but I’m not sure if I am allowed to post p

What is the proper name for Priscacara/Cockerellites fish, Priscacara or Cockerellites?
-
My wife and I took a wonderful trip to the American Quarry near Kemmerer, Wyoming this September. One of the most unusual finds we made was this teeny tiny Priscacara baby. I do love finding the big fish, but this tiny little guy has a lot of attitude. He was by far the smallest fish we found on the trip. edit - for those of you not familiar with US coins - fish is approx. 15 mm nose to tail.

Well what a quick dig. We started our trip to Yellowstone and Mt. Rushmore with a couple of stops and our Search for fossils as we searched for two dig sites on our way. Our first stop was U-dig Fossils in Utah. Here we were suppose to hunt for trilobites but after to talking to a couple of people leaving the site they were very disappointed and found only a couple in their 2 hours. So because I had another site to check out we passed on digging there. Plus at 80.00 per person per day it didn’t not fit our plans. So our next stop ended up at the Fossil Safari in Wyoming where we we

From the album: Green River Formation
This is a very small 2.5 inch long Priscacara indet. These fish can easily be mistaken for a Knightia or an Amphiplaga because of the similarity in shape. -
I just have to brag about @Ptychodus04 a bit more. This man is a master at preparing fossil fish. Someday I hope to be a fraction as good as he is. Here's what he ended up with on the Priscacara I sent him. This was not an easy prep. The right side was completely covered with matrix and the left side exposed. He glued the pieces back together and started prepping on the right side top down. Excellent job Kris. Here's what he sent me.
