The bone on the right appears to be a bovid (bison, cow) metatarsal, while the bone on the left is a humerus, perhaps from a horse. Here's an image of a three-toed horse humerus . . . the contours, if not the overall size, of this bone will be similar to the same bone of a Pleistocene-Recent equus horse.
