Calibration is a core element of radiocarbon dating and is undergoing rapid development on a number of different fronts. This is most obvious in the area of 14C archives suitable for calibration…
Radiocarbon-Based Chronology for Dynastic Egypt
This work 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, which indicates that the New Kingdom started between 1570 and 1544 B.C.E. and the reign of Djoser in the Old Kingdomstarted between 2691 and 2625 B.E.; both cases are earlier than some previous historical estimates.

An Iranian stalagmite record spanning 5.2 ka to 3.7 ka is presented, dated with 25 U/Th ages that provide an average age uncertainty of 31 y (1σ), and finds two periods of increased Mg/Ca, beginning abruptly at 4.51 and 4.26 ka, and lasting 110 and 290 y, respectively.

Radiocarbon dating at the Tell el-Daba site in the Nile Delta has created an enigma for many years. Despite great efforts, the difference of about 120 yr between the chronology based on 14C dates and…
A 5700 year-old human genome and oral microbiome from chewed birch pitch
A 5,700 year-old piece of chewed birch pitch from Denmark is reported from which a complete ancient human genome and oral microbiome DNA is sequenced and it is found that the individual who chewed the pitch was female and that she was genetically more closely related to western hunter-gatherers from mainland Europe thanhunter-gathererrs from central Scandinavia.
High-Precision Bayesian Modeling of Samples Susceptible to Inbuilt Age
The findings of this study suggest that successful corrections can be made for the inherent age offsets of radiocarbon dates on samples susceptible to inbuilt age.

Absolute dates for the end of the Early Bronze Age ancient Near East are of crucial importance for assessing the nature and extent of mid- to late 3rd millennium BC transitions in the Near East and…
Dating the Thera (Santorini) eruption: archaeological and scientific evidence supporting a high chronology
The date of the Late Bronze Age Minoan eruption of the Thera volcano has provoked much debate among archaeologists, not least in a recent issue of Antiquity (‘Bronze Age catastrophe and modern…

This work moves beyond this age-old debate using an interdisciplinary approach that tackles broader questions to advance the understanding of treponemal infection (syphilis, yaws, bejel, and pinta) and its impact on people through time.
Rapid mantle-driven uplift along the Angolan margin in the late Quaternary
Mantle flow can warp Earth’s surface. Reconstructions of surface deformation in Angola over the past 45,000 years reveal rapid uplift of about 2 mm per year, implying that mantle-induced uplift may…
