The Early Anglo-Saxon Period is characterized archaeologically by the regular deposition of artefacts in human graves in England. The scope for dating these objects and graves has long been studied, but it has typically proved easier to identify and enumerate the chronological problems of the material than to solve them. Studying the evidence anew using a co-ordinated suite of dating techniques, both traditional and new, Anglo-Saxon Graves and Grave Goods of the 6th and 7th Centuries AD seeks to address many of these issues.

Part of the Historic England series of Advice and Guidance on using scientific techniques for understanding the Historic Environment, this document provides guidelines for good practice in the use of radiocarbon dating and chronological modelling in archaeology. It gives practical advice on the application of these methods within archaeological projects. It should be used in conjunction with advice given by radiocarbon laboratories and modelling specialists on specific projects. It contains an introduction to the fundamental principles of radiocarbon dating, methods of measurement, and the results produced by laboratories. It then explains radiocarbon calibration, reservoir effects, and provides guidance on the citation of radiocarbon dates. The need for Bayesian Chronological Modelling in the interpretation of radiocarbon dates is then explained, with the components of models identified and methods of model calculation, validation and comparison outlined.A step-by-step guide is then provided to the Bayesian process for employing radiocarbon dating and chronological modelling in archaeology and guidance is then provided in the reporting and citation of radiocarbon dates and Bayesian chronological models.Finally, a range of case studies of varying complexity illustrate the Bayesian process in practice on different kinds of site, from standing buildings, to prehistoric settlements, to geoarchaeological investigations.

This volume holds a datelist of 1202 radiocarbon measurements carried out between 2006 and 2010 on behalf of the Research Department of English Heritage (including 125 undertaken in support of research funded by the Aggregates Levy Sustainability Fund (ALSF) between April 2007 and March 2010). It contains supporting information about the samples and the sites producing them, a comprehensive bibliography, and two indexes for reference and analysis. An introduction provides discussion of the character and taphonomy of the dated samples and information about the methods used for the analyses reported and their calibration.The datelist has been collated from information provided by the submitters of the samples and the dating laboratories. Many of the sites and projects from which dates have been obtained are now published, although further chronological modelling and synthesis may be undertaken on the basis of these data. The purpose of this volume is to provide easy access to the raw scientific and contextual data which may be used in further research.

This volume holds a datelist of 1285 radiocarbon determinations carried out between 1981 and 1988 on behalf of the Ancient Monuments Laboratory of English Heritage. It contains supporting information about the samples and the sites producing them, a comprehensive bibliography, and two indexes for reference and analysis. An introduction provides discussion of the character and taphonomy of the dated samples and information about the methods used for the analyses reported and their calibration.The datelist has been collated from information provided by the submitters of the samples and the dating laboratories. Many of the sites and projects from which dates have been obtained are published, although, when many of these measurements were produced, high-precision calibration was not possible. At this time, there was also only a limited range of statistical techniques available for the analysis of radiocarbon dates. Methodological developments since these measurements were made may allow revised archaeological interpretations to be constructed on the basis of these dates, and so the purpose of this volume is to provide easy access to the raw scientific and contextual data which may be used in further research.

This volume holds a datelist of 882 radiocarbon determinations carried out between 1988 and 1993 on behalf of the Ancient Monuments Laboratory of English Heritage. It contains supporting information about the samples and the sites producing them, a comprehensive bibliography, and two indexes for reference and analysis. An introduction provides discussion of the character and taphonomy of the dated samples and information about the methods used for the analyses reported and their calibration.The datelist has been collated from information provided by the submitters of the samples and the dating laboratories. Many of the sites and projects from which dates have been obtained are published, although, when some of these measurements were produced, high-precision calibration was not possible for much of the radiocarbon timescale. At this time, there was also only a limited range of statistical techniques available for the analysis of radiocarbon dates. Methodological developments since these measurements were made may allow revised archaeological interpretations to be constructed on the basis of these dates, and so the purpose of this volume is to provide easy access to the raw scientific and contextual data which may be used in further research.

This volume holds a datelist of 476 radiocarbon determinations carried out between 2002 and 2004 in support of research funded by English Heritage through the Aggregates Levy Sustainability Fund. It contains supporting information about the samples and the sites producing them, a comprehensive bibliography, and two indexes for reference and analysis. An introduction provides information about the scientific dating undertaken, and methods used for the analyses reported. Details of technical reports available for programmes of luminescence dating and amino-acid racemization funded under this scheme are also provided.The datelist has been collated from information provided by the submitters of samples and the dating laboratories, in order to provide easy access to raw scientific and contextual data which may be used in further research. Many of the sites and projects from which dates have been obtained are published, or are in the process of publication. Full references are given to these reports for those requiring further detail.
