A possible case of renal osteodystrophy in a skeleton from medieval Wharram Percy,England

The skeletal remains of a child aged 13–15 years, recovered from Wharram Percy, England, and dating from AD 960–1700, were examined using gross observation, radiography and scanning electron microscopy. Lesions suggestive of renal osteodystrophy were found. Palaeopathological recognition of renal disease has hitherto relied upon the identification of soft tissue lesions or the presence of urinary calculi. This appears to be the first palaeopathological identification of renal insufficiency on the basis of skeletal changes alone. Copyright © 2007 John Wiley & Sons, Ltd.     

The Tune Viking Ship Reconsidered

The Tune Viking ship has been a riddle for more than 150 years, since being found within a burial in the Oslo fjord area in 1867. It was long thought that the ship's freeboard was too low for it to have crossed the North Sea. Advances in documentation methods and a detailed study of the preserved parts of the ship have provided new data, and this article outlines a new proposal for how the ship looked when it was built in the early 10th century AD. The Tune ship is reinterpreted as a seagoing vessel, in no way inferior to the Oseberg or Gokstad Viking ships.     

Discrimination of Ceramic Surface Finishing by Vertical Scanning Interferometry

Finishing techniques are significant markers of the technological ‘know‐how’ involved in the production of the traditional, clay‐based ceramic ware. In order to provide a reliable tool to discriminate among two main surface processing techniques—that is, smoothing and burnishing—vertical scanning interferometry (VSI), a recently developed non‐destructive technique for analysing the surface roughness and topography, is applied. The smoothed areas have an obvious roughness expressed by linear structures. The latter are made of parallel ridges and trenches with an average depth of 15–20 μm. Burnishing leads to a lower topography and a lower roughness compared to the smoothed surface section. VSI quantifies the spatial distribution of the surface building blocks, which consist of phyllosilicate aggregates of variable size. The statistical treatment of the roughness data obtained by VSI shows that the surface topography provides significant information on the pottery processing and a clear qualitative and quantitative discrimination between different surfaces. VSI supports the reconstitution of the chaîne opératoire for traditional ceramic pottery and the recognition of the surface finishing techniques.     

Scanning electron microscopy of dry hide working tools: The role of abrasives and humidity in microwear polish formation

This paper presents the results of the scanning electron microscopy of a series of experimental tools designed to investigate the role of abrasive agents and humidity in microwear polish formation. The tools—35 end scrapers—were divided into four groups and used to work dry hide. It was found that both humidity and abrasive agents are two basic variables in the development of the microwear polish.     

Comparison of coordinate measurement precision of different landmark types on human crania using a 3D laser scanner and a 3D digitiser: Implications for applications of digital morphometrics

A total of 11 340 Cartesian coordinates of 42 homologous landmarks on five excavated human crania were recorded by three observers using a three‐dimensional (3D) digitiser and computer models created with a 3D laser scanner. The aim was to compare the errors of the coordinate data of landmarks of different types recorded with these two techniques. The results showed that digitiser‐based and 3D model‐based coordinate measurements had overall standard deviations of, respectively, ±0.79 and ±1.05 mm. However, the 3D digitiser yielded the most precise coordinate data for landmarks defined primarily by biological criteria (Type I landmarks), while the 3D laser scanner models yielded the most precise coordinate data for landmarks defined primarily by geometric criteria (Type III landmarks). These findings are likely to influence the research design of future craniometric studies, as they indicate that the suitability of certain landmark types as reference points for geometric operations, such as partial Procrustes analysis, depends on the method by which they are measured. This information is particularly important for retrospective research or for combined databases such as FORDISC or CRANID, which may integrate different types of landmarks recorded by different researchers and/or instruments. Crania displaying poor preservation and surface discoloration yielded larger measurement errors, especially for the 3D model measurements. This is not surprising given that landmarks on 3D models cannot be located using tactile means, but have to be located solely on a visual basis. Nonetheless, even though the digitiser measurements exhibit an overall precision slightly greater than the 3D model measurements, both techniques yield coordinate data with a precision sufficient for most craniometric research.

Three-dimensional (3D) visualisation: the application of terrestrial laser scanning in the investigation of historical Scottish farming townships

Recent developments in digital technologies are heralding significant changes in the way we acquire, visualise and analyse archaeological data. Terrestrial laser scanners can be used to create photo-realistic virtual copies of landscapes, and archaeological features, and offer the potential to improve our understanding of three-dimensional (3D) spatial relationships at study sites. Here we present a methodology for the integration of a high-resolution 3D site model with soil chemical data obtained from an abandoned settlement site located in the Central Highlands of Scotland. At this site, the multi-element concentration in soil, co-visualised within a topographic setting, has an important role to play in elucidating settlement layout and activity. The methods described here are also of significance in archiving sites of archaeological/historical importance where development activities and/or environmental processes may destroy remains, or where access to field sites is restricted.     

Virtual skeletons: using a structured light scanner to create a 3D faunal comparative collection

Appropriate comparative animal skeletons are not always available to faunal analysts for use in identifying archaeofaunal remains. This is especially pertinent when working in locations where no comparative collections are available locally, and the archaeological assemblage cannot be transported to another facility. In order to fill this gap, we are building a virtual comparative faunal collection using a structured light scanner to scan modern skeletal material in 3D. The resulting high resolution 3D color models are a valuable resource for identifying fossil specimens. Scan data can be converted into a variety of formats for viewing and can be transported on a portable digital device for use at field or laboratory localities. In addition, scans can be printed three dimensionally to produce a replica of the scanned skeletal part. A particular advantage of this digital technology is that we can eventually create a complete 3D representation of a taxon's skeleton from scans of several components of what are incomplete skeletons of one animal taxon in a museum collection. The results of our project thus far are available to other researchers and educators by means of the internet. A variety of interested parties could benefit from such a collection, including zooarchaeologists, paleontologists, biologists, teachers and museum curators.     

Flights into the past: full-waveform airborne laser scanning data for archaeological investigation

Airborne Light Detection and Ranging (LiDAR) is a quite recent (mid-1990s) remote sensing technique used to measure terrain elevation. Recent studies have examined the possibility of using LiDAR in archaeological investigations to map and characterize earthworks, to capture features that may be indistinguishable on the ground and to aid the planning of archaeological excavation campaigns.     

The Newport Medieval Ship,Wales, United Kingdom

The Newport Ship is the most substantial late medieval vessel excavated and recovered in Britain in recent years. It was abandoned after extensive salvage, possibly following attempts at repairs to the hull. More than 23 m of the clinker‐built ship were recovered, along with significant artefact and environmental assemblages. Finds point to strong Iberian connections during the active life of the ship, which arrived in Newport in the Severn Estuary, after the spring of AD 1468. The dismantling and recovery of the ship has enabled detailed recording using innovative 3D digital techniques and approaches to hypothetical reconstruction. Publication includes a digital archive hosted by the Archaeological Data Service, a substantial report and this article.
