The dates have been achieved by the methods described in Law and Hedges (1989), Hedges et ai. (1 989; 1992). Determinations with OxA numbers greater than 2095 were measured on the CO, gas ion-source (Bronk and Hedges 1989) rather than on the previous iron-graphite system. In accordance with international radiocarbon convention all dates are expressed in radiocarbon years before AD 1950 (years BP) using the half-life of 5568 years. Errors are quoted as one standard deviation and are based on an assessment of all the contributions to the error in the laboratory isotope ratio measurement. Natural fractionation of carbon isotopes is accounted for by measuring the 613Cvalues relative to PDB (only to within k 0.5-1.0%0)except in a few cases where 6I3Chave been estimated. All combining procedures and significancetests are based on Ward and Wilson (1978). Comments composed by the Laboratory on the basis of information supplied by
