Just another piece of Sandstone?

Here is one more foto of "just another piece of sandstone" or a tool as some people see it. I picked it up from the stone heap (piled up when digging) on the base of the moon pyramid.
It fits smoothely into one hand and could be used as tool, like hammer or grinding device. There is a scar,like an edging on one side of the stone - the stone is not broken - which could result from a rope being tied in order to hold a handle.
It could as well be just a nice looking piece of sandstone, washed by the sea or river to get this peculiar shape.text+foto G.Lukacs
