New data fails to replicate the small-scale radiocarbon anomalies in the early second millennium CE
Over the last decade, the field of radiocarbon analysis has been revolutionized by the discovery of single-year anomalies, because they can be used as markers of space weather events and as time anchors for exact dating. Brehm et al. (2021) recently analyzed two new anomalies, in the years 1052 CE and 1279 CE. These candidates show consecutive year Δ 14 C increases of 5.9‰ and 6.5‰, respectively. In this study, we measured and analyzed dendrochro…
Findings from an in-Depth Annual Tree-Ring Radiocarbon Intercomparison
The radiocarbon ( 14 C) calibration curve so far contains annually resolved data only for a short period of time. With accelerator mass spectrometry (AMS) matching the precision of decay counting, it is now possible to efficiently produce large datasets of annual resolution for calibration purposes using small amounts of wood. The radiocarbon intercomparison on single-year tree-ring samples presented here is the first to investigate specifically …
Informing Conservation
This study tested whether accurate dating by accelerator mass spectrometry (AMS) radiocarbon wiggle-matching of short tree-ring series (~30 annual rings) in the Medieval period could be achieved. Scientific dating plays a central role in the conservation of historic buildings in England. Precise dating helps assess the significance of particular buildings or elements of their fabric, thus allowing us to make informed decisions about their repair …
Bogs, Bodies and Burnt Mounds
The recording and analysis of a burnt mound and adjacent palaeochannel deposits on the floodplain of the River Soar in Leicestershire revealed that the burnt mound was in use, possibly for a number of different purposes, at the transition from the Neolithic to the Bronze Age. An extensive radiocarbon dating programme indicated that the site was revisited. Human remains from the palaeochannel comprised the remains of three individuals, two of whom…
Assessment of Infinite-Age Bones from the Upper Thames Valley, UK, as 14C Background Standards
It is becoming increasingly clear that in order to generate accurate radiocarbon dates for bone collagen samples it is important to determine a sample-specific background correction to account for the greater complexity and higher number of steps in the pretreatment chemistry of this material. To provide suitable samples for the 14 C community, 7 bone samples were obtained from contexts within British gravel quarries, which according to other dat…

IntCal09 and Marine09 Radiocarbon Age Calibration Curves, 0-50,000 Years cal BP
The IntCal04 and Marine04 radiocarbon calibration curves have been updated from 12 cal kBP (cal kBP is here defined as thousands of calibrated years before AD 1950), and extended to 50 cal kBP, utilizing newly available data sets that meet the IntCal Working Group criteria for pristine corals and other carbonates and for quantification of uncertainty in both the 14 C and calendar timescales as established in 2002. No change was made to the curves…
Extended Radiocarbon Calibration in the Anglo-Saxon Period, AD 395–485 and AD 735–805
Radiocarbon dating has been used infrequently as a chronological tool for research in Anglo-Saxon archaeology. Primarily, this is because the uncertainty of calibrated dates provides little advantage over traditional archaeological dating in this period. Recent advances in Bayesian methodology in conjunction with high-precision 14 C dating have, however, created the possibility of both testing and refining the established Anglo-Saxon chronologies…
The Antler Maceheads Dating Project
This paper reports the first examples of direct radiocarbon measurements from antler maceheads, demonstrating that both the middle Thames specimens and those from northern Britain date to the second half of the 4th millennium cal BC. This suggests a degree of contemporaneity between riverine activity in the south and ‘prestige’ burial in the north, although the possibility that this is a function of the radiocarbon calibration curve cannot be dis…
Radiocarbon Calibration in the Anglo-Saxon Period
Radiocarbon dating has been rarely used for chronological problems relating to the Anglo-Saxon period. The “flatness” of the calibration curve and the resultant wide range in calendrical dates provide little advantage over traditional archaeological dating in this period. Recent advances in Bayesian methodology have, however, created the possibility of refining and checking the established chronologies, based on typology of artifacts, against 14 …
The potential significance of dietary offsets for the interpretation of radiocarbon dates
Early Anglian Catterick and Catraeth
The evidence from scattered excavations undertaken over several decades in Catterick is brought together and assessed. The evidence of both settlement and burial indicates activity in the early Anglian period. Indications of status and ethnicity are discussed, and set within their historical context
