C14 Radiocarbon Dating - Sample - SUERC-10605

Sample TWT02 11d Context 11 Burnt black charcoal rich deposit over later set of cobbles 21 reflecting last use of the surface. A pair of dates on charred seaweed are requested to investigate east coast marine effect. Two other dates submitted as control. Under hilwash 6. Most probably agricultural domestic waste: within one year of death unless the seaweed was used as a roofing material, in which case the lapse of time would be slightly longer.
