I found a bone on the Yellowstone River around Reed Point, Montana. I thought it might be a leg bone of a bison or cow. It weighs 12.3 oz. The longest measurement is 9 3/4 inches. It is 4 1/2 inches around in the center of the bone.
Question: what animal does this bone belong to? What might the age be of the bone? Thanks so much for any light you may shed upon my questions and anything I likely forgot to ask.
