Abstract
The discovery of Ancrum Old Bridge (River Teviot, Scotland) in 2018 was a significant archaeological finding for Scotland. Wiggle match radiocarbon dating placed construction of the bridge to around 1340–1360 Cal. AD (95.4 %); a period of political and social instability in the region. Oxygen isotope dendrochronology was applied to refine this date range and to provide a precise felling date for the bridge timbers. Somewhat unexpectedly, a felling date of winter AD 1428/29 was identified. This date was obtained using a reference chronology for the southern United Kingdom and independently verified against a new local isotope chronology developed from native Scottish oak. This new date falls within a more stable period in Scotland’s history which may have been more suited to major construction projects such as Ancrum Old Bridge. These results highlight the importance for radiocarbon end users to consider the nature of dating uncertainty when interpreting results, especially when the probability distribution is multi-modal.
期刊介绍:
Journal of Archaeological Science: Reports is aimed at archaeologists and scientists engaged with the application of scientific techniques and methodologies to all areas of archaeology. The journal focuses on the results of the application of scientific methods to archaeological problems and debates. It will provide a forum for reviews and scientific debate of issues in scientific archaeology and their impact in the wider subject. Journal of Archaeological Science: Reports will publish papers of excellent archaeological science, with regional or wider interest. This will include case studies, reviews and short papers where an established scientific technique sheds light on archaeological questions and debates.
