Hello Eveyrbody! I have a question about Tyrannosaurus rex teeth. A recent study has shown that T.Rex accounted for about 24% of the creatures in the hell creek formation. T.Rex were more common then edmontosaurus. Yet it is usually the most expensive fossil you can get from the hell creek/lance creek. So if Edmontosaurus were less common then T.rex then how come their fossils are way cheaper?

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.

Got another one than has me stumped from the Lance in Wyoming… any ideas guys? Thanks!

I have two fossils from the lance formation that I need help in identifying. The first one is I think maybe an ankylosaur tooth and the second one seems similar to the one from this topic http://www.thefossilforum.com/index.php?/topic/120940-lance-formation-toe-bone/ but it's bigger, and straight. These fossils were found in the Lance fm of Weston County, Wyoming. Thanks for any help. The tooth And the bone

Hey all, wondering what this is. Ive never seen anything like it. Stumps me. Around 2.25 mm by 3mm Thanks!

I'd gotten this tooth fragment from the lance formation of Weston county, Wyoming, it has some serrations and I think that it might be identifiable. The curvature of the fragment. And with this last one, I'm not sure if I'm doing it right. A photo of the tooth with a millimeter scale to show serration density. (it seems to me that there is around 3 serrations per millimeter) Thanks for any help.

@Nanotyrannus35 just sent me a handful of Lance Formation bone fragments to prep. They were mostly turtle shell and we’re pretty fragile in the loosely consolidated Lance Sandstone. A bit of time under the microscope with the micro jack and some low pressure abrasive worked wonders on the bones. They got a healthy dose of Paraloid B72 stabilizer and are headed back to their home today. Some before and after pics are below.

Lance Formation Tyrannosaur or Raptor tooth with strange wear facet.
Nanotyrannus35 posted a topic in Fossil ID
I'd found this small partial tooth about a half an inch long, it looks like it is a theropod tooth and it has a strange wear facet thing at the bottom. I was wondering if I could get some advice on what this tooth is and what the strange wear facet is. Here are the pics. Thanks for any help -
Given the success I had in the White River fm. the week before, my third and final outing of the summer was just icing on the cake to an already phenomenal fossil hunting session. But what I would come to find is that this figurative cake would be getting a massive dose of that sugary goodness, and man it felt sweet. This time around I would be joined by my best friend Michael (@Mickeyb06)who would be taking on his first ever fossil hunting adventure in Wyoming's Lance fm. While it wasn't my intention for this to be his first experience in the field, we made the most of it and it was gre

Real triceratops bones? Or not?
Josesaurus rex posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone, I would like to know if someone can help me identify if precisely these remains correspond to triceratops, or to some indeterminate ceratopsian at least. They all say they are from the Lance Formation, with no county, state, or anything. They are different types of bone, which I will detail below. 1. Sect of the jaw 2. Section of the upper jaw 3. Mandibular sect 4. Ungual, foot claw I await your comments, and thank you very much in advance. -

I found this tooth while looking through matrix from a productive conglomerate site while at home. At first I had no clue what it could be, but the consensus on its ID thread was that likely belonged to Avisaurus. While its hard to conceptualize birds with teeth from our modern perspective, that was the norm for many genera in the Cretaceous. Glad to have found this one and recognize it as a tooth.-

Another shot of the Pectinodon tooth featured earlier in this album, this specimen was found by my dad and is one of two Troodontid teeth in my collection. -

While far less famous than its horned and frilled relatives, Leptoceratops were interesting small herbivores in their own right, likely utilizing their deep set jaws as a deterrent for predators. So far this is the only tooth from this genus I've found so far. -

Most people think of dinosaurs when they hear Lance formation, but I've found that in many of its channel deposits, freshwater mollusks are incredibly common, like this bivalve. -

My first definitive coprolite from Wyoming, could belong to any assortment of animals so I won't slap a label on it to avoid being inaccurate. -
Found this three years back in the Lance Formation. About 50 miles out of Newcastle, WY on a dig trip. Going through some bones I haven’t tried to ID. Any suggestions on this one? It has nice bone surface in a few spots, but isn’t familiar to me.

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 w

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.

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 o

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 tho

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.

Hi everyone, tonight I want to share with you one of my favorite finds from the summer, this absolutely tiny theropod tooth I found looking through anthill matrix in Wyoming's Lance formation. It's currently the smallest theropod tooth in my collection and it's always an interesting contrast when compared to my largest personally found tooth (a Tyrannosaurid from Judith River). It's about 3 mm in length and a bit over 1.5 mm in width. I believe the serrations have been worn off as they are incredibly faint in some areas and absent in others. I'm not sure if the way the light gleans off t

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.

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
