Not sure how one would go about dating drill holes.
I am interested in their shape and what was used to make these holes. Ever find a local example?
Yes, I found a chisel that fits right in these rock holes which are sort of egg shaped from hand drilling or pounding the chisel with it. They didn't have to go very deep for splitting the rocks. Just a few inches down along a rock seam or a scribed line on the boulder or rock face like cutting glass and some sort of wood or leather pounded in the holes then add water letting the expansion split it in a slow process of early masonry.
