strange stone, Armenia - solved

EDIT: both GE- Panoramio and GEC databases has gone meanwhile - post become somewhat useless.

***
just as Panoramio user I ask: -What it is?

check GE photo layer after downloading placemark for photos of a big, porous stone (and other stones) on a hilltop somewhere in Armenia.

strange stone Armenia.kmz (867 B)

can it be artificial or caused by natural processes?

quite a lot passive volcanic cones in the wider location (oGEC contribution by user Hayko linked), so might be some volcanic rock, eroded by elements.(?) 

and here we go:

panoramio shot and oGEC layer around 40°30'37.50"N, 44°56'48.18"E

these were to mark a bronze-age settlement complex and panoramio user states that these are Cup-marks on the stones.

any other opinion?
