Calling on Scotland folks who know the geology and/pre-historic past. I saw an unusual rock picked up on the beach in Scotland and have the area listed. Ayershire and Inverclyde. Not usual for me to be this stumped on an ID. Ideas? I’ll go back there in Reddit to pass along any ideas. #Geology#Geologist#Scotland#Mineral#Rock#Archaeology#Reddit

Other side of the mystery stone in previous photo shows a large area filled in with a green mineral that is almost crystalline and green.
Mystery stone picked up on a beach shows scored parallel lines on the hard stone.
