Pettinain Knocking Stone
Scott Jacobson of Archaeological Heritage Services Ltd has identified a large hollow stone vessel during evaluation trenching conducted in advance of a housing development at Pettinain, South Lanarkshire. This vessel, the base of which was missing, may represent a broken or worn knocking stone, used in the processing of cereal. The stone was found within the fill of a large pit measuring some 4m across by 1.4m deep, which was also found to contain green glaze and brown stoneware pottery, along with glass and clay pipe fragments.
