Could this be a fossil or a body fossil? The white powdery mineral sticks to wet fingers and the black rock underneath looks kind of segmented and symmetrical. But lumpy. It looks like it has a stem or neck with a flat bottom. Found in western pa. About 1.25” x .75” fairly heavy, dark and dense mineral underneath about a 5 mohs hardness. I know it’s probably nothing but worth a shot. Thank you!

I found this hopefully fossil laying on the ground and picked it up because it was symmetric and realized rocks aren’t normally symmetric so thought it could be bone and that’s when I came here Front view back view right view left view bottom view top view
