Fig 1. Soil sample locations within and outside of the multi-individual grave.

(A) Cross-sectional view of sample locations. Samples were collected along three lateral transects (orange stars), within the disturbed grave soils (purple hexagons), and below the grave floor (gray squares) during excavation. Shading within the grave indicates the approximate depth of donor placement. Soils along lateral transects were collected from surface (0‒5 cm) and subsurface (30‒35 cm) soils. Soils within the grave were also collected at the base of the grave (70‒75 cm) and below the grave (85‒90 cm). (B) Top down map view of sampling locations and transect orientations.
