Scientific Dating In Archaeology

A variety of techniques have been developed to provide scientific chronologies of archaeological sites and material culture. These chronologies under-pin the narratives that are generated for prehistoric and other periods. The application of Bayesian statistical analysis to scientific chronologies has been hailed as ‘a revolution in understanding’, and has brought renewed emphasis onto how we generate scientific chronological data, how these data are applied into wider narratives, and the epistemological importance of these data. This volume will provide a timely review of the methods, applications and challenges of applying different scientific dating techniques to archaeological sites and material culture. It will then provide an introduction to Bayesian modelling, and highlight a series of considerations in the application of scientific dating techniques.

Archaeologists and archaeology students have long since needed an authoritative account of the techniques now available to them, designed to be understood by non-scientists. This book fills the gap and it offers a two-tier approach to the subject. The main text is a coherent introduction to the whole field of science-based dating, written in plain langauge for non-scientists. Additional end-notes, however, offer a a more technical understanding, and cater for those who have a scientific and mathematical background.

It is difficult for today's students of archaeology to imagine an era when chronometric dating methods were unavailable. However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision. Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians. Although there are several techniques of using artifacts from superposed strata to measure time, these are rarely if ever differentiated. Rather, common practice is to categorize them under the heading `stratigraphic excavation'. This text distinguishes among the several techniques and argues that stratigraphic excavation tends to result in discontinuous measures of time - a point little appreciated by modern archaeologists. Although not as well known as stratigraphic excavation, two other methods of relative dating have figured important in Americanist archaeology: seriation and the use of index fossils. The latter (like stratigraphic excavation) measures time discontinuously, while the former - in various guises - measures time continuously. Perhaps no other method used in archaeology is as misunderstood as seriation, and the authors provide detailed descriptions and examples of each of its three different techniques. Each method and technique of relative dating is placed in historical perspective, with particular focus on developments in North America, an approach that allows a more complete understanding of the methods described, both in terms of analytical technique and disciplinary history. This text will appeal to all archaeologists, from graduate students to seasoned professionals, who want to learn more about the backbone of archaeological dating.
