I found this rock just outside of Riverton, Wyoming in an area with a lot of chalcedony. I believe the surrounding material is from the Wind River formation. I am unsure if this is some sort of fossil or an interesting rock. Any information would be helpful.This was from the same location as the rock in my previous posting: I believe the surrounding material is from the Wind River formation.

So I recently bought this fish fossil from an antique shop, supposedly, from the Green River formation in Wyoming. The specimen is about 17 centimeters or 6 inches long, I purchased it because of its relatively low price, but most of all, it's quite large! I'm very limited in knowledge of fish, so I figured I would post it here on the forum, any ideas? I'll also add more photos if needed, thanks in advance.

Hi Everyone, I suddenly have a work trip to the Black Hills of South Dakota coming up next week and I'd like to get out and collect some fossils along the way. I'm driving from Denver to Lead, SD and will be driving north on HW 85 and 18 through Newcastle. I'd be really happy to get a few stops in along the way and any potential information would really be great. Unfortunately, I won't have a ton of time to be able to stop and really dig, so some road cuts or target formations would be super helpful for surface collecting. I'm open to every type of fossil. I know there's a lot of fossils in that section of the state so I'm looking forward to hopefully finding some decent stuff! Thanks! Caleb

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.

Hi all! I returned from my trip out west a few days ago and wanted to have some fossils identified before I do my big recap of my experience and my photos from the field. Here are some specimens I found of which I'm not certain of their identity. (This will not be my last post of this type from this trip). 1. Small theropod tooth (Richardoestesia sp.?, Acheroraptor temertyorum?). (There appear to be serrations on the front of the tooth but the majority of them seem to have worn off or did not extend further than midway through the tooth). (Near Newcastle, WY, Lance Fm.). 2. Turtle/Croc toe bone? (Near Newcastle, WY, Lance Fm.). 3. Larvae? (Douglas Pass, Green River Fm.).

FYI @Ptychodus04 @RJB I have some Herkimer Green River Formation fish I just dug up last month and they look really nice but half of them are covered in the sedimentary limestone. There's a bunch that are halfway covered. The matrix is real sticky and just doesn't want to come off. I tried pulling off chunks with some dental tools but had to quickly stop as that was damaging the fossil. Every time I pull up a chunk it takes the fossil with it. I'm thinking about getting a nice air scribe. I found a nice Chicago Pneumatic CP-9361 but have heard that these scribes can be tough on fossils. All these fish are from the split fish layers and I've heard this layer can be challenging to work with. Should I pickup the CP-9361 or go for another scribe such as an AERO/ARO? I can't seem to find an AERO/ARO anywhere. Paleotools sells a modified ARO but those are about $650 and that's a bit past my budget. What are your thoughts? I was also going to get a decent sized air compressor that goes up to 125 PSI. Thanks everyone. Here's a picture with some of the fish. The bottom right fish are good but the rest need to be prepared out.

The REAL Bigfoot. A nearly meter-wide Sauropod dinosaur foot, unearthed 20 years ago from mudstone in northeastern Wyoming, is the largest yet found is described in the attached paper. The other dinosaur skeletons found at the site have yet to be identified, but the size and shape of the foot bones indicate that it once belonged to a brachiosaur. https://peerj.com/articles/5250/ Maltese A, Tschopp E, Holwerda F, Burnham D. (2018) The real Bigfoot: a pes from Wyoming, USA is the largest sauropod pes ever reported and the northern-most occurrence of brachiosaurids in the Upper Jurassic Morrison Formation. PeerJ 6:e5250

Hello, I’m a new member and a novice fossil hunter. I’m headed on a trip thru Colorado, to southwest Wyoming, and then down southern Utah. I know about the pay sites in Wyoming, does anyone have any suggestions fossil sites from central thru northwest Colorado, and eastern Utah. Sorry if this is a pretty broad question.

Fossil Forum Friends, I put some fish up for possible trading on the trades section and wise @Fossildude19 reached out to me with a possible identification as a Amphiplaga brachyptera. This species makes up less than 1% of the known fish collected in the Green River Formation. Upon closer inspection it appears to be that species or it might just be a disarticulated Knightia. I really can't tell as I'm not a fish expert. Please provide your input. If it is a A. brachyptera can someone please PM me with a quote for preparing the fish and once it's prepared I'll get it framed at Michael's craft shop in a custom frame with an identification plaque. Shouldn't be a tough prep job. The fish is small and the matrix soft I just don't want to screw it up if it is a rare one. See attached. FYI @Ptychodus04 @sseth @FossilDudeCO @RJB

Utah trilobites and Wyoming fish surplus
Fossil-Hound posted a topic in Member-to-Member Fossil Trades
I have a surplus of fossils from Utah and Wyoming. From UT I have a bunch of Elrathia and Asaphiscus trilobites. From Wyoming fossil fish mainly Knightia but I do have one Mioplosus. What I'm looking for are trilobites outside of Utah, ammonites, and shark teeth or any other kind of tooth such as Therapod, Cetacean, crocodile, etc. Here's a picture of some of the fossils. I also have some Chesapecten from Maryland sitting in my desk drawers.

@Ptychodus04 is preparing a fossil fish in exchange for some on the side web development (web page). Here's where he is at with the preparation and I must say that I'm very pleased with the results. This is going to turn out to be one amazing fish. Here's a before and after. The before was a fish that was broken in half and in need of some restoration and repair but is mostly there. Kris is really working his magic on this one.

I was fortunate enough to be able to visit the American Fossil quarry in Kemmerer Wyoming this past week and had an amazing time. @sseth and his business partners do an incredible job running the quarry and made my experience there a memorable one by giving me the opportunity to find some beautiful fossils over the two days I was there. These finds include a nice Mioplosus, a beautiful Phareodus and dozens of Knightia. I highly recommend the American Fossil Quarry and I am looking to make a second trip back this next summer.

I found this interesting piece of rock while hiking in the Snake River Canyon NE of Alpine, Wyoming. My first thought was it might be a coral so I looked at images of fossilized corals and it most closely resembled Rugose Coral from the Devonian. Please check out the photos and let me know what you think. Thanks!

Last summer on my trip out west, I found these teeth at a Lance Formation microsite in Wyoming. Many of the fossils were found through splitting a yellowish-orange concretion filled matrix, while others were free from it. This site was on the same ranch where I found my theropod hand claw but in separate locality. It's rather late (EST) at the time I'm posting this but wanted to show some of the teeth I found and was hoping I could get some help identifying them. 1. Pectinodon bakkeri 2. Richardoestesia sp. (?) 3. Lizard/ Worn Herbivorous Dinosaur Tooth (?)

Had a phenomenal time digging up Eocene freshwater vertebrae fossils in Wyoming this past weekend at @sseth and @FossilDudeCO famous American Fossil Quarry. Managed to convince my cousin, his two sons, and my family to join. @sseth set us up with our own rocks to split and he was very informative, showing us how to split the rock and what to look for. We all had a really good time. Here are some of the highlights. Matt's two sons Logan and Wesley had a blast. Here's their cart full of Knightia's. A sneak peak at some of the multi slabs I hauled away. On the bottom is a slab with five complete fish. There's one hiding in the sun and another top right that needs to be prepared out. Some of the finds. Some of these fish need some prep work to fully uncover. A personal favorite was the largest Diplomystus I have ever found. I should of put something in the picture for scale but this fish is nearly a foot wide. The heartbreaker of the day was this well preserve Mioplosus. The top and bottom halves of the head are missing! Still a nice looking fish and I'll use it for referencing the species in the years to come. Wesley holding up a decent sized Knightia. A view of the limestone rocks we were splitting. @sseth recovered a crocodile tooth from a small slab such as the ones pictured here some time ago. Matt trimming down his finds on the rock saw. My cousin Matt and his son Wesley showing off some of their prized fish. A front view of the rock quarry. There's a lot to offer at the site. Wes lining up fish for his dad to cut. Matt sawing away. The remains of the slabs after we split them down. We kept revisiting and respiting slabs. It was a lot of fun. The Seth clan hanging out under the shade, escaping the hot sun and dust. Couldn't resist snapping this photo. I really need to get one of these decals. @sseth on the left side. He was super helpful in showing us what to look for. That Mososaur skull on his shirt was recovered my him in Morocco. That is super neat. I'm holding up a large Knightia near Logan and Wes. Matt and his sons getting pumped to descend 50 million years into the Eocene. At 9:00am we were among the first on sight and we were all super excited to get to the digging and exploring. Wes (left) and Logan (right) braving the dust and sun to find Eocene fossils. Have to start them off young! Having dinner at a local Mexican restaurant in Kemmerer. The food was really good. We ordered Carne Asada that came with spicy salsa. Matt kept telling the waitress to bring out the "Gringo" salsa.

Hey guys!! My UPS box of everything I brought back from my pay-to-dig trip in Wyoming came in today!! Here's what I ended up with fully unboxed. I brought home a bunch of half fish to work on my preparing skills before I tackle the complete ones. The last two big pieces at the end measure 24x18 approx and have 6 or 7 fish on them. I'll take more pictures of them tonight as I un(bubble)wrap them.

Over the holiday weekend we managed to head North to Wyoming. A few pictures and a few "finds" enjoy Started off with a Badger Headed to a place called "talking rock" Checked out some of the indian work and took a few pictures. The Indians would sit in these spaces and work on there arrowheads. Not much shade to be found out on the prairie. Lots of small pieces covering the ground that had been worked.
