I found this in some matrix from the Lance Formation in Wyoming and wondered if it is an ankylosaur tooth. The hash marks are 1mm. Thanks for any help.

Asineops (Greek for "donkey-faced") squamifrons was first described by Cope as having an affinity to the pirat perch family. Later, with more detailed study, this species was found to lack the diagnostic characters of that family. Thus it is not yet clearly assignable to order. Although this species is much rarer in the Fossil Lake sediments than in Lake Gosiute deposits, the specimens from Fossil Lake are much larger than those from Lake Gosiute.

This partial mandible was found on private land in the Willwood Formation of the Bighorn Basin. It is likely a right M1 and partial M2. I've been able to identifying it down to Perissodactyla indet. but cannot go further. I'm leaning towards something like Cardiolophus but I'm not sure. Would appreciate any help.

I'll be honest, I've put off writing this trip report for far too long. Between work, school and general procrastination I have delayed this post for over 7 months. Perhaps there's a silver lining to me writing this in the middle of winter, it could act as a nice break from the grey & cold conditions many of us are facing this season. Hopefully you all enjoy a dose of warmth from a trip which I enjoyed greatly. Ok ready? Let's go. My morning started around 4:30, ungodly hours for me generally, but I woke up excited for what lay ahead. Less than a half hour later we were on our way headed south to Boston. While we always leave much earlier than I would like. there's something peaceful about being able to drive through the streets of the greater Boston area without having to deal with its notoriously bad drivers. We made it to Logan and I gave my parents a goodbye hug after we pulled my bags from the car. The flight was smooth and with only 1 layover, I had made it to Rapid City by early afternoon. Soon after I landed in SD, I caught a ride to Newcastle with PaleoProspectors Founder and Director, Dr. Steve Nicklas. When we reached our destination across the border in Wyoming, I quickly began to acclimate to the motel room which would be my home for the next three weeks. This week I would meet and befriend several new people including Quincy @Opabinia Blues, another paleo enthusiast my age, and several of Steve's archaeology students who came to help him dig on a titanothere bonebed. This week would be spent mostly on the Lance formation, with one day spent on the White River. Week 1, Day 1: We started the morning at some hillside exposures overlooking a plain along the Little Cheyenne River. This is one of my favorite areas on the ranch. I started the day off hot with a nice sized turtle claw, unfortunately missing the tip. Brachychampsa alligatoroid tooth. A view of the slope I was hunting. A nice ceratopsid spit tooth. A tiny crocodilian tooth. Myledaphus (guitarfish) tooth. As the morning turned into afternoon, I made my way to the base of the exposures.

I found this odd vertebra in Wyoming's Lance fm. over the summer. I was told by a guide that it may be a turtle cervical vertebra, but I wanted to see what other forum members thought. It's about 1.5 cm long and around 1.3 cm in width.

This past summer's trip to Wyoming provided no shortage of interesting and bizarre finds. This tooth was found at a channel deposit in the Lance fm. and is about 5 mm in length and 2 mm in width. It appears to be a theropod tooth based on the overall morphology, but lacks serrations unlike the all the non avian theropods in the formation. I'm not sure if the serrations were worn off or were never there in the first place. Or perhaps based on the small size it belonged to a young individual with developing teeth. The theropod it most closely resembles in my opinion is Richardoestesia, as it's only slightly curved and the base is similar to examples of that genus in my collection. I'd appreciate any input you may have.

Hi everyone, I found this small tooth over the summer in a Lance formation channel deposit in Wyoming. In the field I didn't know what to make of it, too recurved and compressed to be croc, no visible serrations either so probably not a non avian theropod. Months later I took a closer look at it and continued to search for its potential identity. I thought to myself could it be a mammal canine. After some online browsing I couldn't find a match for anything in the Hell Creek/Lance fauna. However, after posting it on an instagram story, I got a few suggestions. One of the more intriguing of those suggestions came from @Mioplosus_Lover24 who believed it was probably a varanoid lizard, potentially Palaeosaniwa. I looked for any images of Palaeosaniwa teeth online and came up empty handed, but I did find some similarities between my tooth and that of the Cretaceous Mongolian varanoid Estesia and a modern example of a monitor teeth. The length is approximately 6 mm and the width at the base is 2 mm. monitor skull I found online Estesia mongoliensis skull described in a 2013 paper by Norell & Yi

Hello, my name is Michael and I'm from New Hampshire. This past summer I was hunting with PaleoProspectors in Wyoming with my best friend @PaleoNoel in mostly the White River and Lance formation. One day in the Lance formation we found what appears to be a piece of claw from an Ornithomimid. It looks like the leftmost claw of the foot with a gradual curve and a large groove running down the side possibly due to erosion. I'd love to hear if anybody has any ideas on what this could be and I'd greatly appreciate an ID. The width is 1.7 cm at the base and 1.0 cm at the top. It is 2.6 cm long.

A while back I collected a group of bivalves from the Frontier Formation (Cretaceous) just south of Kemmerer (Lincoln County) Wyoming and I am having some trouble pinning down an ID. The formation is known for containing Crassostrea soleniscus and Inoceramus, but these are neither of those. Based on my Texas Cretaceous Bivalves book, they could be some species of Panopea but I am not at all certain of that. Unfortunately, although I have quite a number of samples, there aren't any that expose the dentition so that is a bit of a disadvantage. I'm hoping one of our Wyoming experts and/or bivalve experts have seen these before as I'm pretty sure they are not uncommon. My internet searches have failed me so far. Or if anyone can suggest a good literature source for Wyoming Cretaceous bivalves, I am happy to to do some reading and deciphering. Thanks very much for any help you can provide. The first two pictures are two views of the same specimen, the third picture is a seperate one.

Hello, Last week, I found this baculite eroding out of a concretion in Casper, WY along the recreational bike path. The shale erodes out of the hillside and is presumably part of the Cretaceous Cody Fm. Can someone help me verify and identify this baculite? Are there any references to the stratigraphy and or fossil assemblages in the Casper area? Sorry for the poor photo quality. Thank you!

I found this interestingly pitted piece of bone in Wyoming's Lance formation over the summer and my initial thoughts were ankylosaurian osteoderm. I've been wrong in the past with various Ceratopsid skull elements deceiving me, but I am hopeful to add this to my comparatively short list of remains from these living tanks. I'd appreciate any feedback from my fellow forum members. Dimensions are about 8 cm in length, 5 cm in width, ~3 cm in depth.

I found this in 1989 on the upper Powder River in Wyoming. It was in an area with lots of these baculite-shaped things. I thought it would make a great knife handle so that's what I did. However, I've never seen anything like it. It has the general shape of a baculite but the exterior seems to be covered by something. I get the "sense" of a type of sea weed, or a jelly fish or something, but I doubt very seriously something soft like that could fossilize. So I am looking for an expert to tell me what I have. Also interesting, is different aspects of the "raised" features are different colors. If you can enlarge these pictures, you might be able to see the roundish darker thing. Thanks in advance for any input.

I think I was here long ago because it said my email was in use. I am back seeking information on a fossil I found. I found it in 1989 on the upper Powder River in Wyoming.

Also interesting, is different aspects of the "raised" features are different colors. I will post in the fossil ID forum after I figure out how to reduce the size of my photographs. If you can enlarge these pictures, you might be able to see the roundish darker thing. Thanks in advance for any input.

Ornithischian vertebra - Lance Fm. Thescelosaurus? Hadrosaur?
Opabinia Blues posted a topic in Fossil ID
Hello! This is a very worn, very eroded ornithischian vertebra from the Lance Formation of Wyoming. It was in three pieces that I recently glued back together, I found all the pieces wrapped in foil together in the box I brought back from the trip. It’s from my trip there this summer, though I don’t remember collecting this specific bone. My immediate thought based on size and shape is Thescelosaurus, though I have seen some small Hadrosaur verts that look kind of like this one. I just hope it isn’t too worn/eroded that no guesses at an ID can be made! Thanks!

Happy New Year everyone. Tonight I thought I might post a fossil whose identity I wanted to confirm. I found it in Wyoming's Lance formation this summer and someone told me it might be a Pachycephalosaur premaxillary tooth because of it's carinae and ridges at the base. However after comparing my tooth to examples I could find online I felt that this ID was incorrect. Eventually I looked back over one of @Troodon's threads and found a jaw labelled as parasaniwa and those teeth matched what I had found. My tooth is about 6 mm long and about 3 mm wide.

My latest completion. I like this one but still prefer the Mioplosus. I'm looking for a Priscacara next. Maybe Santa will bring me a fossil for Christmas!

Hi everyone. I found this little fossil recently while working through a sandy conglomerate matrix I brought back from this summer's hunt in Wyoming's Lance fm. I believe it's a dermal denticle from some variety of cartilaginous fish, my first guess would be the Hybodont shark Lonchidion, but the guitarfish Myledaphus is also incredibly common in these sediments, however I haven't seen any pictures of denticles belonging to the latter or close relatives. It's about 2 mm long and about 1.5 mm tall. I would love to hear some input. Thanks, Noel

Yesterday we decided to get out a bit for the first time in months and go to the Wyoming State Museum. We were the only visitors so we had the museum to ourselves, which was pretty nice. It houses a rich history of Native Americans, wildlife, mining, military, and fossils. I'm only going to post the fossil related photos though.

I dug this up in Wyoming and was told it's a Mioplosus. The soft sandstone came off with only a bit of effort. Now I'm on to a harder crystalized matrix around the most delicate areas. I don't want to lose any of the carbon so I'm asking for help. I've used dental tools and pen razors so far. I see amazing, beautifully completed fossils on this site with no sandstone on them at all. Is there a method or tool I am unaware of?

I bought this prepare your own fossil fish either knightia or diplomystus so I could prepare something for the first time which is why it looks like this don’t judge. I was wondering two things actually, one is it a knightia or diplo? And two are all green river fish this hard? I know I didn’t do a good prep job but was the fish poorly preserved as well? It was paper thin in some places and the fish doesn’t look whole it looks like its bones got moved after it died. Oh it’s also about 3 inches from the mouth to the “end” of the tail

Green River Fish question
fossilguy312 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello all, I have been long searching for an exceptionally high/museum quality aspiration example from Green River. I recently have found myself with the opportunity to acquire this specimen. I've been told that there is a small amount of restoration on the tail of the Priscacara but I don't know exactly how much/what it entails yet. I'd ideally prefer a specimen with 0% restoration but I don't know how realistic that is. For scale, the diplo is 18" long, I'm told. It's obviously pretty cool that this is a Priscacara aspiration as my understanding is that this is pretty uncommon. I'd be very curious to hear your feedback on this piece in general, your thoughts on the restoration, and to hear your suggestions on whether or not this is the "right" piece to add to my collection (last part is a personal decision, I know...). I don't mind waiting to find the perfect piece... but I also don't know how realistic it is to find one much better as this one seems pretty nice to my eye. I wish the tail were poking out a bit farther but hey I guess I give the diplo credit for getting it that far down before expiring... Really appreciate your thoughts.

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 picture on FossilsForSale.com that is pretty much identical, and is listed as a crocodile.

Another bargain from our favorite auction site. I didn't have any fish from the 18 inch layer, and the price was right. It is also exceptionally preserved, with all fins present. Knightia eocaena Green River Formation, Eocene. Wyoming. Fish is 4 inches (10 cm) in length.© © 2020 Tim Jones
