C14 Radiocarbon Dating - Sample - SUERC-2434

A sheep bone (Sample 34785), found in a middeny fill 3358 within a shallow depression 3304. Sealed by a lens of loamy midden 3361. The whole earth sample taken from fill 3358 contained an angler fish jaw, sheep bone and a fragment of human radius. Charred grain was also present. The deposit is located at the base of a series of upcast deposits deriving from the digging of the broch ditch. The bone is likely to have been deliberately included in the fill deposit.
