    Death and Display in the North Atlantic: The Bronze and Iron Age Human Remains from Cnip, Lewis, Outer Hebrides

    YesThis paper revisits the series of disarticulated human remains discovered during the 1980s excavations of the Cnip wheelhouse complex in Lewis. Four fragments of human bone, including two worked cranial fragments, were originally dated to the 1st centuries BC/AD based on stratigraphic association. Osteoarchaeological reanalysis and AMS dating now provide a broader cultural context for these remains and indicate that at least one adult cranium was brought to the site more than a thousand years after the death of the individual to whom it had belonged

    Atlas Toolkit: Fast registration of 3D morphological datasets in the absence of landmarks

    Get PDF
    Image registration is a gateway technology for Developmental Systems Biology, enabling computational analysis of related datasets within a shared coordinate system. Many registration tools rely on landmarks to ensure that datasets are correctly aligned; yet suitable landmarks are not present in many datasets. Atlas Toolkit is a Fiji/ImageJ plugin collection offering elastic group-wise registration of 3D morphological datasets, guided by segmentation of the interesting morphology. We demonstrate the method by combinatorial mapping of cell signalling events in the developing eyes of chick embryos, and use the integrated datasets to predictively enumerate Gene Regulatory Network states

    Archaeological signatures of landscape and settlement change on the Isle of Harris

    Between 2004 and 2011, a programme of archaeological investigation by the University of Birmingham on the Isle of Harris, a distinctive island forming part of the Western Isles of Scotland, has allowed the archaeological remains of this enigmatic place to be further characterised and understood. Despite intensive archaeological interest in the archipelago for a number of decades, the Isle of Harris has been overlooked and only now are we beginning to identify the archaeological resource and make comparisons to the wealth of published data from islands such as the Uists, Barra and Lewis. This paper highlights some generic overall patterns of archaeological signatures on the Isle which has been identified through a range of archaeological methods including field walking, intrusive excavation, aerial reconnaissance, geophysical and topographical survey, and documentary research. Several key case studies will be introduced including upland shieling complexes and mulitperiod settlement sites on the west coast machair systems. The purpose of the paper is not to present a gazetteer of the results of the work to date, but to highlight some of the key findings with a view to demonstrating that the Isle of Harris is directly comparable with the archaeologically rich landscapes of the other islands

    A Model of Coastal Wetland Palaeogeography and Archaeological Narratives : Loch Spynie, Northern Scotland

    This paper presents a new model for the palaeogeography of an important archaeological region in northern Scotland – the former Loch Spynie, Moray. The method employed refines existing glacio-isostatic adjustment and relative sea-level models for the Holocene with open data sources of geomorphological, geotechnical and archaeological data to constrain the proposed former extent of marine, estuarine and other wetland environment through time. The study area is shown to be an important isolation basin that is highly likely to preserve dateable relative sea-level index points. The resulting palaeogeographic model for the former Loch Spynie estuary is then used to develop an archaeological narrative of coastal and maritime activity in later prehistory critiquing and supporting an emergent paradigm in understanding later prehistory in northern Scotland. This study demonstrates how it is possible to develop palaeogeographic models at scales useful for site-based archaeological interpretation bridging a problematic gap in archaeological narratives
