ID would be great or any info, location B----- Ranch Microsite USA. Is this a quality tooth, was thinking of making a pendant with it.

Hi everyone, I found this little, mostly complete vertebra in the Hell Creek formation of South Dakota in 2019. I don't really know what to make of it as it's very porous, and amphiplatyan (flat on both sides), although I'm not sure how much of that could be attributable to wear. I believe it's safe to cross of squamate (due to lack of concavity) and champsosaur (overall shape) off the list. While most of the crocodilian verebrae I have found in the hell creek have have a convex and concave end, I am aware that some can be found that are flat sided. The porosity of the bone makes me hopeful that it's theropod, but am not by any means discounting mammal, croc or any other possibility. Dimensions are 1 cm in length, .8 cm in height from base to the end of the process and about 1.2 cm. I would like to know the opinions of my fellow members.

Another tiny toe found in a North Dakota Hell Creek microsite, this little digit is 1 cm in length and about 5 mm in width. I know it's difficult to identify isolated digits but I was hoping we could potentially narrow it down to a general ID, turtle, croc, champ or other.

I found this tiny, slender bone at a Hell Creek microsite during my trip to the Dakotas in 2019 with PaleoProspectors. I'm not sure what it came from, but I'm hoping it's theropod, avian or otherwise. It's missing a section of the outer layer of bone and I believe the interior is hollow & filled in with the ironstone common in the formation. The dimensions are 1.7 cm in length and about 3 mm in width. I would appreciate any feedback you may have. In situ shot from the site: The closeup shots did not come out exactly how I wanted them lighting and detail wise. If you would like me to retake them or get different angles I'll happily do so.

Here's an interesting fossil I found from the summer which I am just getting around to posting. I believe it's a piece of turtle beak based on its shape and the numerous holes which I believe are part of the vascular structure of the beak, rather than just the standard cancellous tissue of bone. Here's a modern one I found online for comparison. And one from a marine turtle on the Oceans of Kansas website.

Hello everyone, I found this nice claw in South Dakota over the summer and have yet to find a definitive match for its identity. It's about a centimeter and a half long.

Hey everyone, I found this little jaw section at a microsite in North Dakota's Hell Creek formation this past summer and I'm finally getting around to posting about it. I believe it's fish, possibly gar, but I'm not sure. I'd like to know people's opinions. It's about 1.3 centimeters long. Thanks, Noel

Hey everyone, I found this spit tooth in Montana's Judith River formation over the summer and believe it belongs to a ceratopsid as it looks similar to ones I've found in Hell Creek and Lance. This would be cool as they are significantly rarer in this formation than in HC & L , despite a wider variety of species. Let me know what you think. It's about 1.5 cm long and 1 cm wide.

I just "rediscovered" what I believe to be a cretaceous mammal tooth, I placed it with the triceratops and edmontosaurus spit teeth thinking it was a sliver of one. Taking a closer look I think it could be the crown of a small mammal's tooth. I want to know what you think (It's about 7 millimeters long).

Here's the second piece of crocodilian osteoderm I found in Montana in the summer of 2017. It may also be from Leidyosuchus. -

This osteoderm may belong to Leidyosuchus. -

Here we have the tooth tip from a Tyrannosaurid I found at a microsite in Northern MT. Teeth, especially fragmentary ones like these are nearly impossible to identify accurately as the differences between those of Gorgosaurus and Daspletosaurus (the two species of tyrannosaur from the JRF) are difficult to distinguish.-

This little tooth likely comes from the alligatoroid Leidyosuchus. However I could be wrong and I'm basing that idea off of it being the only crocodilian other than deinosuchus described from the formation. -

I found this on an anthill and initially thought it was a croc/alligator tooth but after closer inspection I believe it's a premax tooth from the ornithopod. Thescelosaurus neglectus Late Cretaceous (Maastrichtian~ 66 mya) Lance formation -

After cleaning some of the excess dirt off the fossil I found that it had a tooth still unerupted. One of the cooler fossils I found on this trip. Late Cretaceous (Maastrichtian~ 66 mya) Lance formation -

I found this piece and initially thought it could be champsosaur, later on some forum members believed it to be crocodilian so it likely belonged to Borealosuchus, Brachychampsa or another unnamed genus. Late Cretaceous (Maastrichtian~ 66 mya) Lance formation -

Jury is still out about the identity of this digit but I believe it's either crocodilian (Borealosuchus, Brachychampsa or other) or a turtle (numerous species). Late Cretaceous (Maastrichtian~ 66 mya) Lance formation -

cf. Lonchidion selachus Late Cretaceous (Maastrichtian~ 66 mya) Lance formation Hybodonts were a group of sharks which lasted an incredibly long period of time, however many went extinct with the non-avian dinosaurs. Lonchidion is a freshwater variety which went extinct at the end of the Cretaceous. -
