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

I'd found this partial tooth from the lance formation and was wondering if it would be identifiable. It's pretty partial so I wouldn't be surprised if it's unidentifiable. Here are the pictures The side The front The top And the bottom Thanks for any help.

I have found 2 vertebral arches in my box of matrix from the lance fm. I was wondering if it is possible to identify the arches without the centrums. Here are the pictures, the fossils are from weston county, wyoming Vertebral Arch 1 And vertebral arch 2 Thanks for any help!

I had found this vertebra in the box of matrix I'd gotten for my birthday. I think that it might be either a crocodile or a Pachycephalosaurus caudal vertebra, I was hoping that you guys might be able to identify it. It was found in the Lance formation of Weston County, Wyoming. Here are the pictures. Scale is in millimeters. Thanks for any help!

What's the difference between the Lance fm and the Hell Creek fm?
Nanotyrannus35 posted a topic in Questions & Answers
So what is the difference between the lance fm and the hell creek fm? They both have the same dinosaur species and from what I can tell, other vertebrate species. The only difference that I can think of is that the lance fm is in Wyoming while the hell creek fm is in South Dakota, Montana, and North Dakota. -
I'd found this partial tooth in some lance fm matrix. It doesn't look like crocodile so I think that it might be Richardoestesia. Here are the pictures. It's about a half inch long.

Hey everybody! I wanted to make a thread sharing with you some of the smaller fossils in my collection, many of which I've photographed using my digital microscope. Some of these I've found in the field at microsites or channel deposits, while others I've found at home searching through matrix. I hope you enjoy! Our journey begins in Wyoming's Lance formation: A Pectinodon tooth my dad found in 2017. A tooth that was identified by other forum members as potentially Avisaurus, also found in 2017. A tooth I initially called Paronychodon, although the small & worn denticles may suggest otherwise. Found in 2020. A tooth which was once the smallest in my collection at around 3 mm., potentially Acheroraptor but currently is indeterminate. Found in 2020. Probably my smallest crocodilian osteoderm in good shape, found in 2019. A tiny dermal denticle, potentially from Myledaphus. Found in 2020. The smallest mammal tooth in my collection, an itty bitty multituberculate I found at home working on conglomerate matrix in 2019. A nodosaur tooth (Denversaurus) found in 2020. A collection of small fish mouth plates (cf. Cyclurus) from 2020. A salamander premaxilla (cf. Scapherpeton) found in 2020. A Thescelosaurus premax tooth from 2020. A view of some of the Lance fm. anthill matrix I brought home to search, with a piece of fish mouth plate in the center

For Christmas, I'd gotten a box of matrix from the Lance formation. I have some fossils that I am not sure what they are and would like to get your opinions. All of these fossils are from the Lance formation of Weston Co. WY. The first one is I think a theropod ungual, missing both the distal and proximal ends. Here are the pictures. The second one I'm pretty sure is a partial Edmontosaurus metacarpal. The The third one might be a ornithischian ungual. And here is the final one, I think that it might be a jaw section.

Why are there so many late Cretaceous dinosaur fossil bearing formations in the western usa? In just Montana alone, there is the Hell Creek fm, the Lance fm, the Judith River fm and the Two Medicine fm. The fauna in these different formations are also similar, it's kind of confusing.

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.

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.

I came upon this bone while sorting my old boxes. It looks like the dorsal edge of a turtle marginal. I say this because of the slit on the inner surface resembles the split marginals make. It is the surface pattern that puzzles me. I am unfamiliar with the freshwater turtles from this area and hoping someone can identify this.

Hey guys, I saw this Tyrannosaurid tooth from the Lance creek formation, USA. I was wondering if it was a juvenile T. rex tooth. It’s 0,5 inches long. Thanks for the imput

Hello, anyone able to help with this one? Going through my old "fossil" folder, I found this one I got 10 years ago bought as "Albertosaurus" from Lance Formation. Now, looking online I'm seeing Albertosaurus as not being from Lance. Indeed, only valid Tyrannosaur from there is looking like Rex Would this be better labelled as Undetermined Tyrannosaur, a T rex, or has Albertosaurus actually been found there? Apologies for pictures. The actual fossil is in storage box at my UK home, I'm in Taiwan and wont be going back there until COVID is over. So, hopefully these two older pics are enough to narrow it down. There are some serrations, which I believe seperates it from the juvenile teeth usually sold as Aublysodon?

I found this in some Lance formation matrix. Might it be an ankylosaurus tooth? If not, what do you think it may be? Thanks for any help. The hash marks are 1mm.

Hello I have a juvenile rex tooth from Lance Formation to trade looking for dinosaur fossils thats are not from morocco.

Hello this bones are form lance formation what could they be form? Thanks.

Hello all, I am new to the fossil forum ( obviously). A little bit about myself: I have formal training and education in vertebrate Paleontology. I double majored in Geology/ Zoology in college and continued to get a Phd in vertebrate Paleontology. I was the adjunct professor of dinosaur Biology at the local community college until the shutdown. My specialization is theropod dinosaurs, but I have experience with a variety of fossil animals. My area of least experience is probably fossil mammals, so you will likely see me posting some pics of bones on here for second opinions. When it comes to dinosaurs I've worked with basically everything. If you can think of a dinosaur, I've probably dug up something like it. I've also worked on mapping sauropod and pterosaur tracks of the Morrison fm. Since moving to Oregon ( United States) I have had difficulty finding work in my fields of study, so I decided to start trying to survive on my own. I am a bit out of practice ( 5 years of not practicing paleo), but have recently started getting back into the swing of things. I have begun research into reconstructing paleo climate of the oregon coast using bivalve shells, specifically pecten, as a biological index for measuring chemical changes in sea water. I have mainly been looking into the newportian stage of the Astoria fm ( 15-18 million year old rocks). This represents the mid- Miocene. I have collected several vertebrate fossils on the coast, most of which haven't been prepped or I'd yet, but I know for a fact that I have a couple of whale vertebrae ( one juvenile, one mature) as well as a large juvenile pinniped/ walrus, a deep sea fish vert cross section ( complete with diploe), a section of shoulder blade and rib from (?), a vertebra from something like an otter, and a bone I have yet to make any decisions on. I look forward to getting to know all of you, and share knowledge.

Tip was missing and was repaired. White marks are from plant roots pulling minerals off the surface.

Going through finds that haven’t been ID-ed yet from a trip to the Lance Formation. The find looks scute like, but I’m not an expert. It appears this maybe ID-able by its features. Let me know your thoughts. Thanks!

I found this tooth in some matrix from the Lance formation from Wyoming. It reminds me a little of a croc tooth, but could it be something else. The division markers are 1mm. Thanks

I found this tooth in some matrix from the Lance formation in Wyoming. It doesn't have any serrations and it isn't as round as most of the crocodile teeth I have found. Any ideas? The scale is 1mm. Thanks.

Hey everyone! If someone could post a pic of what a HC champsosaur tooth looks like that would be appreciated. I have not found one yet (I thought I did a while ago but they turned out to be from Melvius) but I am interested to see what they really look like as most of what I see online look like fish teeth or crocodile teeth. Thanks, Noel
