Radiocarbon dating calibration methods az chaffey dating football scottsdale
The first excavations were performed prior to WWII, and supported the biblical chronology.
When Kathleen Kenyon came away from her study in the 1950s and essentially announced ‘I see no evidence for the destruction of Joshua here,’ she was basing her opinions, in part, on the new field of radiocarbon dating.
I read the scientific article on the carbon dating done on the Jericho site written by Bruins and Van Der Plicht.
The current internationally-ratified radiocarbon calibration curve for terrestrial samples from the Southern Hemisphere is SHCal04.
For the remaining period 12,400-26,000 cal yr BP, the curve is derived from independently dated marine samples such as foraminifera and corals.
A new internationally-ratified calibration curve (Int Cal09) covering the whole radiocarbon timescale (~50,000 cal yr) is being prepared by the Int Cal Working Group.
See: The walls of Jericho, The story of Jericho, and Q and A pages on the Ice Age and radiometric dating.

This curve covers the past 11,000 cal yr, which is based on the dendrochronologically-dated tree rings for the last millennium and on model ages for the remaining period.
