Bones found in Central Montana around the Missouri River, near the Upper Missouri River Breaks national monument

I found this bone late one evening hiking with a friend, we had known there were “dinosaur” bones found within the rock in the area that we had seen before, but then we kept stumbling and found this crazy thing! It was near the very top layer of the geological layers seen in the picture. I was just curious if anyone had any idea what it could be, I can give more information on the location if needed. Pictures 1-8 are the first bone, I included some photos of the area and layer it was found in.

I also have attached a second picture, this one was found down low, maybe a half mile from the river and it is ground level. The last three pictures are of this bone, I tried to include where it was found as well.

I was just curious if anyone had any ideas or thought about either bone, thanks!
