Could these all be from 1 animal? Found these scattered about in Pierre shale but all within 50ft. Wonder if I should try to find the origin of where they are coming from. The paddle bone looked small compare to the verts. Would this be an adult? ID on parts would be helpful to. Thanks

I found this fossil today in the badlands of south Dakota in a crevice at the bottom of a butte. I did not remove it but am impatient and with the photos I supplied, the paleontologist at the visitors center had a hard time identifying it and I am extremely curious to know what it may be. The round part of the bottom picture continues to be almost perfect oval through the top, however a chunk had broken off there. The discolored brown line in the crevice in the center of the first picture appeared to be bone that just barely breached the surface of the specimen (too hard to picture).

Identification: On the ranch where this tooth was found, only T. prorsus skulls have been found in the 30+ years the company has operated there, lending a very probable, precise identification for this Ceratopsian tooth. (T. prorsus was one of the last dinosaurs, younger than T. horridus. The two species are also stratigraphically separated in the Hell Creek Fm.[2], so it makes sense that one may only find one species in a particular deposit.) For most Ceratopsid teeth (from the Hell Creek Fm., for example), only association with an identifiable skull can allow for identification beyond C

ø 4.5cm. Fox Hills Formation Maastrichtian Late Cretaceous From Cheyenne River, South Dakota, USA I went for a reasonably priced purchase, even though it was only one half. -
I have no idea what bone this is or what critter it came from. Very fossilized. Found in south central SD.

I’m pretty sure this is a tooth but have never seen anything like it

Found in south central SD.

A first for me and the most beautiful tooth I’ve ever found! Pretty excited about this one. Obviously not an expert here but I think I’ve got it narrowed down to juvenile mastodon. Hopefully I can get a positive ID from the experts! Miocene, south central SD.

First bone I have found with this shape. Found in south central South Dakota. Miocene

I have a pretty good idea of what this is but I would like to hear from the experts!

Not sure about this one. Looks a little different than my other horse and bison teeth.

(Posted in SD forum as well, feel free to move) I thought this would be an appropriate addition- my hope is that this map will allow forum users to plan trips to SD! Threw this thing together for you guys in some spare time at work. The map shows the extent of common fossil bearing strata in the state of South Dakota, as well as some "no-go" areas- reservations and the like. If you guys want a certain area zoomed in on let me know! FossilsSD.pdf

I picked up a little Hell Creek lot that hat this fossilized bone in it. I think it might be a theropod toe bone from looking around on the web at Hell Creek bones. Anyone with more experience (most everyone) have any opinions?

I'm restoring a titanothere cervical vert and process, and I want to be accurate. Can anyone suggest a research site? The sites I've found have the articulated spinal columns , which don't have the detail I need. I need at least a front and rear view. Thanks! Barb

Found this near Lewis and Clark lake. We are thinking it's a shark tooth! Anyone have any more details?

Hello, I found a fossil in the fox hills formation (Upper Cretaceous) around 6 miles east of Timber Lake, SD. I believe it is part of a dinosaur bone, or atleast a large vertebrate and was wondering if there was enough of the sample for a positive ID. The area in which I found it in is known to be a lagoonal deposition environment and I found the fossil in a thick bed of bivalves. Mosasaurs have been found in the formation but I'm not sure that this bone belongs to one of those. I tried to mostly clean it off, but there is still some encrustation.

I found this in southwest South Dakota on private property. There are three different items posted here. Appear to be bones. Can you help? Thanks
