I don’t see any worked edges. It’s not an artifact; just a rock.How could this be?
I get your point, but yes, I usually see shadows on top of things. I hold my hand between the sun and my car: shadow on top of my car. But no, I don’t normally see items cast a shadow on top of themselves. Semantics? LOLThat's easy. Look at the "suspended" boulder. Ever see a shadow on the *top* of an object?
