C14 Radiocarbon Dating - Sample - SUERC-10851

Sample CH06#56 Context 604 Floor layer 604 in Area B (north of the main excavations). Deposit of dark brown sand forming a house floor or old ground surface adjacent to an irregular stone wall (601). It overlay a layer of brown sand (602) and was sealed by a deep deposit of windblown sand (600). Unstratified human bones from Area B have widely differing dates (GU-9822; 3300 ± 55 BP and GU-9823; 1875 ± 45 BP). Site Phase 4. The carbonised barley grain is most likely to have been deposited as the result of activities within the house/structure in which material became charred from contact with the hearth fire. Very little time is likely to have elapsed between the seed's charring and its incorporation into the archaeological context of the floor deposit.
