This article presents the results of interdisciplinary analysis of samples from the Czarnówko archaeological site in northern Poland, reporting the first radiocarbon dates for the site in comparison with its relative chronology. The site is of high importance because of its scale and opulence of artifacts. It was used for over 900 yr, from the 7th century BC up to the 3rd century AD, by populations of different cultures (the Lusatian, Pomeranian, Oksywie, and Wielbark). Samples of charcoal, wood, and textile were collected from different features, most of them from burials. Charcoal was taken from cremation pits, while wood was sampled from coffins in skeletal burials. Among samples collected during archaeological excavations in 2008 and 2010, 20 were chosen for14C dating and macro-and microscopic observations. Images taken using a scanning electron microscope revealed the microstructure and preservation level of the specimens. An emphasis was also placed on geomorphological and geological research of the site area to gain information about the environmental conditions influencing the samples’ preservation state, e.g. pH, type, origin and permeability of sediment, and accumulation of organic matter. The obtained calibrated14C ages are in agreement with the relative chronology based on the typology of artifacts and stratigraphic site reconstructions. © 2017 by the Arizona Board of Regents on behalf of the University of Arizona.

Archaeology is a destructive discipline, and, unfortunately, the majority of methods employed by archaeologists to record and preserve the archaeological record consist of two-dimensional representations of three-dimensional (3D) subjects. Recent breakthroughs in 3D technology, however, have the potential to revolutionize the discipline. In recent years, multiple software suites capable of generating spatially accurate, photorealistic 3D models with a series of digital photographs have become available. Following a successful season of field testing in 2011, the Tel Akko Total Archaeology Project (Akko, Israel) expanded the use of Agisoft's PhotoScan Pro-one of the commercially available software suites-to test the accuracy and suitability of the program for archaeological applications at multiple scales. After two years of field testing, it is clear that the implementation of PhotoScan Pro in archaeology facilitates unprecedented accuracy in field recording and digital heritage management, and provides a new outlet for the dissemination of archaeological data. ©Trustees of Boston University 2013.

Multiview (n-view or multiple view) 3D reconstruction is the computationally complex process by which a full 3D model is derived from a series of overlapping images. It is based on research in the field of computer vision, which in turn relies on older methods from photogrammetry. This report presents a multiview reconstruction tool chain composed from various freely available, open source components and a practical application example in the form of a 3D model of an archaeological site. © 2011 Elsevier Ltd.

This paper discusses the results of the investigation of Pleistocene sediments at the Royal Oak Portal (ROP) site on the new Crossrail scheme near Paddington Station, London. The site was sampled and recorded in May 2011 by archaeologists from Oxford Archaeology commissioned by Crossrail Ltd. The investigation revealed a sedimentary sequence associated with cool climate waterlain deposition towards the edge of the River Westbourne floodplain. During excavation an assemblage of around 100 identifiable large mammal bones was recovered, dating to the Late Pleistocene. The major concentration of bones, from bison and reindeer, was located and excavated from a shallow sequence of sediments. Analysis of the bones indicates that they represent a natural death assemblage, scavenged and subsequently disarticulated, transported by water, exposed and further dispersed and broken by trampling. The site is of regional and national importance because the assemblage derives from a well-constrained geological context, with associated dating evidence suggesting accumulation during the later parts of Marine Isotope Stage (MIS) 5 and continuing within MIS 4. The site is also of significance because it is one of a growing number of recently discovered sites away from the main fluvial archive for the British Middle and Upper Pleistocene. These sites have the potential to add significantly to our understanding of parts of the Pleistocene record that remain difficult to document through the investigation of the more active systems associated with major rivers such as the Thames, Severn or Trent. © 2013 The Geologists' Association.

Vegetation History and Archaeobotany | Year: 2014

While conducting a review of published archaeobotanical remains from southern and central England, it became apparent that contamination (intrusion and residuality) was a notable, recurring theme in many assemblages. This problem is most acute in some key periods in which plant assemblages are generally less abundant than in others, such as the Neolithic and the early medieval (Saxon) periods. While most archaeobotanists are aware of the potential for contamination, without direct dates it is often difficult to demonstrate and it is likely to have obscured the true patterns in the data. Contamination becomes particularly problematic once poorly or incorrectly phased data enter the secondary literature. A number of case studies are presented, including newly dated material from a high profile excavation at Durrington Walls, Wiltshire. The importance of direct dating of plant remains is discussed. © 2014, Springer-Verlag Berlin Heidelberg.

High resolution incremental isotopic analysis of the dentine from early forming teeth, especially first molars (M1s), provides a means to assess the effects of poor childhood nutrition and healthcare on individuals in an assemblage where there are no infants to study. This approach is applied to an 18th and 19th century cemetery population associated with St Saviour's Almshouse burial ground in Southwark, London, to assess whether, or how, early dietary history, including weaning age, influenced health and nutritional status. The results show a general pattern in which non-breast milk foods were introduced before or by 6 months of age, as indicated by elevated δ15N during this period. Almost all individuals for which we also have second molar (M2) records, showed lower δ15N values from a very young age (>1 year) until approximately 8-10 years, compared to adult values. The overall results show a significant difference in δ1 3C (p = 0 to 4sf, F=17.327) and a weaker statistical difference in δ15N between males and females (p=0.019, F=5.581). One possible cause of this is a difference in the diet of males and females early in life, or alternatively, a greater susceptibility of males to nutritional deprivation compared to females. The latter argument is strengthened by a significant difference in the incidence of enamel hypoplasia between the males and females, with 7.7% of male teeth showing defects, compared to 3.9% of females. © 2014 Wiley Periodicals, Inc.

Landscapes (United Kingdom) | Year: 2014

Corsham, in rural Wiltshire south-west of Chippenham (UK), is a multilayered above-ground and below-ground site that encompasses historic components relating to nineteenth-and twentieth-century industrial and military heritage. This article focuses on its subterranean side, which is of particular archaeological significance but which we argue can be investigated and experienced as a landscape. Created in the nineteenth century for the mining of Bath stone, in the Second World War its network of deep tunnels and caverns was converted to accommodate an ammunition depot, aircraft engine factory and an RAF command centre. Arguably the most significant use of this vast below-ground domain, however, came during the Cold War, as the UK’s Central Government War Headquarters, (CGWHQ), known at the time under code names such as ‘Burlington’ and ‘Turnstile’. Finally decommissioned by the military in 2004, after almost 40 years of ‘mothballing’ and slow decay, it has now become a focus of heritage study and interest, and (although inaccessible) is emerging as an iconic landscape of memory, parts of which now have statutory protection. This article presents the results of applying landscape-based approaches to the subterranean domain of what is too easily considered purely as a heritage site. © Oxbow Books Ltd 2014.
