Moving away from Trilobites, I wanted to try my hand at a fish. This is my rendition of Priscacara serrata, a common species of the Miocene, in the Green River Formation. The fish looks like a Perch, or a Bass, because all three are in the Percinae Family. Priscacara is an extinct member.

I've just visited this hill directly north of the Trump National Golf Course (yes, the president owned a golf course in my city ) which I was told by a museum docent had fossil fish scales. Here's what I found which could possibly be fish scale fossils, but I need a full confirmation on this. Some notes -All three rocks are associated- they were all part of a giant piece of shale rock which was broken into pieces when I found it. -The "fish scales" are a more darker or orange brown. -I think I was unable to capture the best possible detail due to the absence of natural lighting which made details more camouflaged. -Each "fish scale" lie on only one layer, throwing off the possibility of it being a crystal. -The black stuff are dendrites or a similar type. -Found in the Palos Verdes Hills, directly north of the Trump National Golf Course. Rock 1 Rock 2 Rock 3 Is this my first ever fossil find or another bust?

Went to the Fossil Fest in Round Rock, and I came home with a kit to clean off a fossil fish. Though it'd be worth a try. The slab is from Wyoming, about 3" tall and 5" long, and they provided a tool that was really just a paintbrush with a steel nail attached to the other end. It's a bit beat up. Some of that was me and my inexperience, some of it was already like that. A lot of fin rays were already broken, and I'm pretty sure some of the fins were outright missing their tips even before I got into here. Maybe something nibbled on the edges a bit? I'm looking for some advice on how to do better, basically. Most of the skin came off, for one thing. There were especially loose flakes of matrix that looked like I could remove them with my fingertips, and whenever I touched one with the nail to take it off, it took the skin with it. I'm not sure if that was my fault or not. It also looks sort of like some of the skin was pulled towards the tail somehow. Damage or not, I think it worked out pretty well for my first try, at least it's mostly intact.

Hi all, I saw this Diplomystus online for sale. I was surprised by the prize: 20$! But then I started to get a little suspicious. Though most fakes are mosasaurs and keichousaurs, I heard that fossil fish from the Green River formation are often re-painted so that they look more splendid. Though I am pretty sure that this specimen here was originally 100% real, I think that it might have been painted on. Is my suspicion right, or is this one 100% natural? Here is the info they gave: What do you think? Thanks, Max

Hi, I just got back from Kemmerer with a large amount of fish fossils to prep and have an Aero scribe. I was wondering if a Micro Jack would be better as the vibration of the Aero knocks some of the scales off. If the answer is yes, which Micro Jack would be best in your opinion. If anyone has other prep suggestions I would also be interested. I've read all of the old posts that I could find on the subject.

Here's a good question. I do have several big fossil fish from the Green River Formation and already have a good idea how to hang those big monsters, but what about the smaller fossil fishes on smaller slabs of rock that are not framed? There has to be a way? @FossilDudeCO Fish like these in the picture and a whole lot more. RB

I have found fish tails previously -- this one is smaller and in quality condition. WHich types of fish moght have a vertical tail like this one.. Salt water? Fresh Water. Approximate size L .8 x W 1.2 Inches Now the JAWS!!! H 1.0 x L 2.3 inches The teeth are 2-3 mm. I have not previously found anything like this.

These have been a long time coming but they arrived just yesterday. These are fish concretions from Morocco. Ive never had any experience with these and have only seen about 3 fish from Morocco that are any good, so this is truly a gamble. But if you don't gamble, you cant win. Im going to go on the prep attack on one of these today and see what happens. im excited and nervous at the same time. Wish me luck. RB

The fish is from Goulmima, Morocco. The size of the specimen is 131/4" by 3" by 11/2" I am wondering if it is Ichthyodectidae

Ok - this topic should stir up some conversation. As I was working on prepping a Green River fossil fish, I noticed some fibers were being removed next to the fish bones by my needle vise. I assume they were 50 million year old tissue still somewhat intact. So I got to thinking that what if it contained ancient pathogens that might have somehow survived since the fish expired. Looking up on the Internet I see that scientists have discovered 30 million year old viruses that have come back to life! The good news is that I appear to still be healthy! But... Is it possible that we fossil hunters could be exposed to something yet unknown and what could result? Just wondering. Has anyone else thought about this or have there been any studies along this line? Maybe me thinks too much!

Does anyone know the id of these fossil fish? they came from Liaoning.

I was cleaning out my garage this past weekend and ran into a fish fossil I collected and put in a box about a decade ago. I collected it with a friend out in the diatomaceous earth quarries near Hazen Nevada. This is where the small Gasterosteus and Fundulus fish are found in great abundance. But from my understanding anything else is pretty rare. This fish is probably about 2 feet in length when assembled from the pieces. See photos, any insights on what I have would be appreciated.

Hi Guys, Just thought id get an opinion or two on my fossil fish from the Green River's "18 inch layer". It's an 8 and a half inch Diplomystus Dentatus that i bought for 75 bucks from an ebay seller who prepares all his fossil fish himself. There was no mention of paint/restoration in the description and the guy seems very reputable but i can't help question if it has been painted. I would ask him myself but it's a bit weird to say "hey mate, you know that fish i got from you like 6 months ago? Yeah, um, was it painted?". So that's why i am asking here. What do you guys think? I've put close up pics of the whole fish as well as a full body shot.
