C14 Radiocarbon Dating - Sample - AA-45626

Right humerus plus right femur (Sample SK7) of an extended, partially articulated, supine burial of an immature individual aligned North-west to South-east (head in NW). The grave (342) was cut into a sandy midden 309/311 which was then rapidly redeposited as a virtually indistinguishable fill (f341). The burial was then sealed by 318/325, a sandy shell midden layer. Unlike SK5 and SK6 a small stone upright has been placed either side of the head. This burial was articulated so presumably little time elapsed between death and burial.
