C14 dates: GU-7286 Mixed charcoal from small hearth. BP 2080 +/- 70, d13C -26.0 (which equals 356 BC – 67 AD at 2 sigma).
GU-7283 Mixed charcoal from possible post-hole. BP 2210 +/- 50, d13C -26.0 (which equals 393 BC – 166 BC at 2 sigma).
AA-26971 Birch charcoal from same context as GU-7283. BP 2060 +/- 45, d13C -26.1 (196 BC – 48 AD at 2 sigma).
AA-26972 Hazel charcoal from same context as GU-7283. BP 1980 +/- 45, d13C -26.5 (which equals 92 BC – 127 AD at 2 sigma).
AA-26976 Heather charcoal from same context as GU-7283. BP 2055 +/- 45, d13C -26.6 (which equals 191 BC – 50 AD at 2 sigma).
GU-7285 Mixed charcoal from the fill of the ring-ditch, which contains material from both Neolithic and Iron Age. This -average- date is probably misleading. BP 3770 +/- 80, d13C -26.1 (which equals 2462 BC – 1979 BC at 2 sigma).
AA-26977 Birch charcoal from same context as GU-7285. BP 1805 +/- 45, d13C -26.1 (which equals 86 AD – 339 AD at 2 sigma).
AA-26978 Hazel charcoal from same context as GU-7285. BP 4105 +/- 50, d13C -26.8 (which equals 2875 BC – 2497 BC at 2 sigma).
AA-26979 Alder charcoal from same context as GU-7285. BP 4215 +/- 50, d13C -26.9 (which equals 2912 BC - 2633 BC at 2 sigma).
GU-7284 mixed charcoal from cut interpreted as posthole; 400 to 50 cal BC.
AA-26973 piece of elm from post-hole 150 cal BC to 130 cal AD;
AA-26974 single piece from same context as GU-7284 - 350 cal BC to 20 cal AD; AA-26975 single piece of hazel from post-hole - 110 cal BC to 130 cal AD.
The above calibrated dates (except the last 4) are derived from OxCal 4.2
