Radiocarbon-Based Chronology for Dynastic Egypt

The historical chronologies for dynastic Egypt are based on reign lengths inferred from written and archaeological evidence. These floating chronologies are linked to the absolute calendar by a few ancient astronomical observations, which remain a source of debate. We used 211 radiocarbon measurements made on samples from short-lived plants, together with a Bayesian model incorporating historical information on reign lengths, to produce a chronology for dynastic Egypt. A small offset (19 radiocarbon years older) in radiocarbon levels in the Nile Valley is probably a growing-season effect. Our radiocarbon data indicate that the New Kingdom started between 1570 and 1544 B.C.E., and the reign of Djoser in the Old Kingdom started between 2691 and 2625 B.C.E.; both cases are earlier than some previous historical estimates.

I själva verket stämmer siffrorna mycket bra med den konventionella kronologin. Däremot går de inte alls ihop med den s k "ultralåga" kronologin som lanserats det senaste årtiondet, men det har ju varit tydligt att den stämmer dåligt med C14-dateringarna redan tidigare.
