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.

Hello People Looking for help with identifying the owner of this Atlas bone found in the White River Formation in Wyoming.
-
Last season was a great season at the quarry. For those who dont know, our quarry is in the Fossil Butte member of the Green River Formation in southern Wyoming. We ended up with three turtles coming out. Two of them were large turtles, 48" (Apalone heteroglypta) and 52" (Chisternon undatum), and they were found stacked above one another, separated by only 7 inches, and a tiny little guy that is a new species. I will post pictures of these amazing fossils as they are finished up. We have Brock @ebrocklds doing the preparation work for us on these three amazing fossils. Here are pictures of the Apalone. You can see it took us a bit of time to excavate and collect all of the tiny pieces. It was in a large fracture zone in the rock. Enjoy.

The wife and I finally got to explore a hill that I had been looking at for years. This was in early September of 2016. The back roads of Northern Colorado enjoy the scenery. Didn't take very long to start finding things. All I had with me was a water bottle for size. The ridge we were standing on.

Been lurking here on your forum for a long time. I really enjoy the pictures and stories. Back in 2013 I was exploring, fixing fence on a ranch in the Shirley Basin area of Wyoming. Not to far from the famous Como Bluffs. Found this in the creek. At one time I had contacted a gentleman (Neil Lander)? from the museum of natural science I believe was in New York. He gave me the name and the time it lived. My computer crashed and I lost it all. If one of you could help I would appreciate it. The large one with the spikes. About 13 inches across, spikes are 2 inches. Thanks

Diplomystus dentatus Fish Fossil GREEN RIVER formation, Kemmerer, Wyoming USA Eocene age (56 Million years ago) Diplomystus is an extinct genus of freshwater clupeomorph fish distantly related to modern-day extant herrings, alewives, and sardines. The genus was first named and described by Edward Drinker Cope in 1877. There are seven species of Diplomystus: D. dentatus (Cope, 1877), D. birdii, D. dubetreiti, D. shengliensis (Chang 1983), D. kokuraensis (Uyeno 1979), D. primotinus (Uyeno 1979), and D. altiformis. D. dentatus (Cope, 1877) is well known from lower Eocene deposits from the Green River Formation in Wyoming. Specimens range from larval size to 65 cm and are commonly found in close association with the extinct herring Knightia sp. The Green River Formation is the remnant of a large lake whose mud would eventually be transformed into soft calcite-bearing shale. D. kokuraensis (Uyeno 1979), D. primotinus (Uyeno 1979), and D. altiformis were dominant members of an Early Cretaceous lake fauna (the "Diplomystus-Wakinoichthys Fauna") in what is now Japan and Korea. Dimensions: 4.6 Inches Long & 3 Inches Wide (Plate) Fish is 4.2 Inches Long & 1.5 Inch Wide. Diplomystus Dentatus morphology, including its upturned mouth, is prototypic of a surface feeding fish. The genus is herrings that likely fed on small surface-dwelling fish as Knightia is evidenced by numerous fossils found with Knightia is the stomach or mouth. The unusual chemistry of fossil lake prevented decay and scavenging of dead organisms while millimeter-thick layers of alternating limestone matter slowly accumulated. The result is laminated limestones that contained the highest concentration of fossil fish in the world. These fish, other aquatic organisms, and associated geologic features make Fossil Lake the world's best Paleogene record of the freshwater lake ecosystem.

My family stumbled across quite a few pieces of fossilized bone over the weekend in Southeast Wyoming. We counted 40+ pieces that are between 2-6” in height and oval in shape. They were spread out over an area approx 40’ wide. We also found what might be a tooth along with sereral other unidentifiable pieces. This was a very exciting find for us and I would love to learn more about what (or who) we found! Please let me know if you need additional photographs or any other info.

Phareodus encaustus fish fossil Green River Formation, Kemmerer Wyoming Eocene Age (56 Million Years ago) Phareodus is a genus of freshwater fish from the Eocene to the Oligocene of Australia, Europe and North America. This genus includes at least four species, P. testis (Leidy, 1873) and P. encaustus of North America, P. muelleri of Europe, and P. queenslandicus of Australia. Representatives have been found from the middle Eocene to the Oligocene of Australia, Europe and North America, including the Green River Formation in Wyoming, United States P. testis was a freshwater fish with an oval outline, a small head, and a slightly pointed snout. Its dorsal and anal fins were situated posteriorly, with the anal fin being larger. Its caudal fin was slightly forked. It had small pelvic fins but long, narrow pectoral finsPhareodus belongs to the osteoglossids, which are represented today by the Arawana. Arawana is found in tropical and semitropical fresh waters of South America, central Africa, Southeast Asia, and northern Australia. Phareodus lived during the Eocene Epoch and is about 55 million years old They can be found in the fine-grained limestone layers of the River Formation. Fifty million years ago ancient Fossil Lake existed in what is now southwest Wyoming. Of its estimated maximum extent of 930 square miles, approximately 500 square miles of sediment remain. The 230 square miles across the center of the ancient lake-bed contain exceptionally fossiliferous sediments and associated geologic features including deltas, beaches, springs, and rocks from the center and near shore environments. Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Infraphylum: Gnathostomata Superclass: Osteichthyes Class: Actinopterygii Family: Osteoglossidae Genus: †Phareodus Species: †encaustus
