Early Bronze Jericho: High-precision ¹⁴C dates of short-lived palaeobotanic remains

Reliable series of high-precision radiocarbon dates in a stratified archaeological context are of great importance for interdisciplinary chronological and historical studies. The Early Bronze Age in the Near East is characterized by the beginning of the great civilizations in Egypt and Mesopotamia, as well as by urbanization in the Levant. We present stratified high-precision dates of short-lived material of Tell es-Sultan (Jericho), covering Late Proto-Urban/EB I, EB II and EB III layers from Trench III. Our calibrated dates, refined by Bayesian sequence analysis involving Gibbs sampling, are ca. 150-300 yr older than conventional archaeological age assessments. The corpus of ¹⁴C dates measured in the first decades after the discovery of ¹⁴C dating should not be taken too seriously. The ¹⁴C dates of Jericho measured by the British Museum ¹⁴C laboratory in 1971 appear to be erroneous.
