Holocene coastal change and geoarchaeology at Howick, Northumberland, UK

The recent discovery of one of the earliest Mesolithic occupation sites in northern Britain, at Howick on the Northumberland coast, in association with multiperiod archaeological evidence nearby, highlights the importance of UK coastal settings as focii of human occupation through the Holocene. Environmental evidence from a nearby river valley (8.15 m of sediment ranging in age from about 12 000 cal. BP to the present) records local and regional environmental change. Twenty-four radiocarbon dates based on plant macrofossils provide a strong chronological framework. Calcareous microfossil assemblages (foraminifera, ostracods) have been recovered from the fine-grained sediments, recording a change from marine through to brackish and eventually freshwater conditions between about 8200 and 6500 cal. BP. A preliminary pollen study of the core has permitted a reconstruction of the regional vegetation as it responded to climatic amelioration and human influence upon the landscape. Radiocarbon dating and sedimentological evidence indicates a major hiatus between approximately 11 000 and 8000 years BP (including the period of Mesolithic occupation), represented by a 30 cm layer of coarse sands and sandstone pebbles, probably the result of a significant high-energy event dated to about 8300 cal. BP. Although not a typical tsunami deposit, the age and context suggests that this may be associated with the Storegga Slide event, already well-documented along the eastern coast of Scotland. The sedimentary and biological remains at Howick record environmental change over much of the Holocene and are compared with other environmental change records from the region to provide an environmental framework for the archaeology of this coastline.

Craig Rhos-y-felin: a Welsh bluestone megalith quarry for Stonehenge

Abstract The long-distance transport of the bluestones from south Wales to Stonehenge is one of the most remarkable achievements of Neolithic societies in north-west Europe. Where precisely these stones were quarried, when they were extracted and how they were transported has long been a subject of speculation, experiment and controversy. The discovery of a megalithic bluestone quarry at Craig Rhos-y-felin in 2011 marked a turning point in this research. Subsequent excavations have provided details of the quarrying process along with direct dating evidence for the extraction of bluestone monoliths at this location, demonstrating both Neolithic and Early Bronze Age activity.

Prehistoric and Dark Age Settlement Remains from Cheviot Quarry, Milfield Basin, Northumberland

Archaeological excavations in advance of quarrying at Cheviot Quarry, Northumb. have produced important evidence for Neolithic, Late Bronze Age and Dark Age settlements. Neolithic pit features containing domestic midden material including broken pottery, lithics and cereal grains from two distinct parts of the quarry have provided evidence for what is interpreted as settlement and subsistence activity from the Early and Later Neolithic periods. Together with the Neolithic remains from the nearby sites at Thirlings and those recently excavated at Lanton Quarry, it provides evidence for significant, and perhaps intensive, settlement on the sand and gravel terraces of the Milfield Plain throughout the Neolithic. Indeed, these sites provide the precursors to the better known ceremonial and henge complex located nearby which probably dates to the Beaker period. Radiocarbon determinations associated with the full sequence of Neolithic pottery have been obtained from Cheviot Quarry and analysis of the residues adhering to the ceramics has provided some of the earliest evidence for dairy farming in the region, as well as information relating to other dietary and subsistence practices. Two substantial roundhouses with porches, internal hearths and pits containing domestic refuse, provide the first evidence for Late Bronze Age lowland settlement in the region. The botanical macrofossil and faunal evidence, together with the pottery residues, show clear evidence for arable and pastoral activity in a small, unenclosed farming settlement. A detailed programme of radiocarbon dating and the application of Bayesian modelling has shown that these two buildings are contemporary and date to the tenth century cal. BC. In addition to this prehistoric archaeology, three Dark Age, rectangular, post-built buildings were also discovered on the site and have been radiocarbon dated to the fifth or early sixth century cal. AD. These substantial, although heavily truncated, structures are thought to represent the homesteads of a small farming community, although the lack of material culture makes understanding their use and cultural attribution problematic. Because of their early date these buildings could have belonged to either post-Roman British inhabitants or perhaps early Anglo-Saxon mercenaries or settlers. A reconstruction of one of these buildings has been built close to the site at the nearby Maelmin Heritage Trail where it can be visited by the public.

The Early Medieval Origin of Perth, Scotland

The radiocarbon results (and Bayesian modeling) of 15 samples of carbonized food residues removed from the external surface of rim sherds of cooking pots indicate that shellyware pottery first appeared in Perth, Scotland, around cal AD 9101020 (95% probability) and that it had disappeared by cal AD 10201140 (95% probability). Previously, it had been suggested that this pottery could not date to before AD 1150. These data, together with 14C analyses carried out on leather artifacts and a sample of wattle from a ditch lining, also demonstrate that there was occupation in Perth about 100 yr or more prior to the granting of royal burgh status to Perth in the 1120s.

Reconstructing Battles and Battlefields: Scientific Solutions to Historical Problems at Bannockburn, Scotland

Abstract The need for scientists to add objective data to historical studies is argued using as a case study the battle of Bannockburn in 1314. The terrain was critical in this battle, as in so many others, but cannot be understood from the few primary sources, which are not contemporary and are strongly biased. Scientific techniques can cut through hyperbole. The methodology and techniques used to better understand the landscape around the battle are briefly discussed, particularly new advances in radiocarbon dating which enable analysis to approach the chronological precision of the archaeologist, if not the historian. Our data are argued to have clarified muddled interpretations.

Report on the Excavation at the Duggleby Howe Causewayed Enclosure, North Yorkshire, May—July 2009

The Neolithic round barrow at Duggleby Howe comprises a substantial mound surrounded by a large causewayed ditch. The mound covers a rich Middle Neolithic burial sequence, as revealed by Mortimers nineteenth-century excavations, and occupies a position on the northern valley side of the Gypsey Race, near to the streams source. Following the recent radiocarbon dating of the burial sequence and primary mound building, a small research excavation was undertaken across the ditch of the large, penannular causewayed enclosure that surrounds the mound primarily in order to obtain artefactual and ecofactual material from which to construct a relative and absolute chronology for the ditch sequence(s).

Late Bronze Age Pottery Production: Evidence from a 12th–11th century cal bc Settlement at Tinney's Lane, Sherborne, Dorset

Excavations at Tinneys Lane, Sherborne in 2002 uncovered extensive evidence for Late Bronze Age settlement and pottery production, dating from a short time period probably within the 12th or 11th century cal bc . Well-preserved deposits of burnt stone, broken vessels, and burnt sherds, together with resulting debris redeposited in associated pits, were accompanied by a series of post-hole structures interpreted as round-houses and four-post settings. Environmental evidence in the form of charcoal, charred plant remains, and molluscs has provided important information concerning sources of fuel and water for pottery production as well as allowing a reconstruction of the local vegetation. Finds of fired clay, metal, stone, shale, flint, and bone include items from distant sources, informing topics such as site status and exchange, and include many categories of tools and equipment that would have been used within the pottery-making processes. Analysis of the spatial distribution of these finds amongst the structures and surviving layers of burning has allowed the definition of a series of industrial activity areas, each comprising one or more round-houses, a four-post structure, bonfire bases or pits used for firing, and other pits with specific related functions. Altogether the site has provided some of the best evidence for pottery production within prehistoric Britain.

The development of the Pictish symbol system: inscribing identity beyond the edges of Empire

The date of unique symbolic carvings, from various contexts across north and east Scotland, has been debated for over a century. Excavations at key sites and direct dating of engraved bone artefacts have allowed for a more precise chronology, extending from the third/fourth centuries AD, broadly contemporaneous with other non-vernacular scripts developed beyond the frontiers of the Roman Empire, to the ninth century AD. These symbols were probably an elaborate, non-alphabetic writing system, a Pictish response to broader European changes in power and identity during the transition from the Roman Empire to the early medieval period.

Radiocarbon Wiggle-Match Dating in the Intertidal Zone

ABSTRACT Radiocarbon wiggle-match dating is a technique that can combine the versatility of radiocarbon dating with chronological information from tree-rings. This makes it useful in contexts where timbers are preserved, but dendrochronological dating is impossible. As intertidal and marine timbers are waterlogged, this can favor their preservation and hence allow wiggle-match 14C dating, which can be of significant help in deriving relatively precise chronologies for a range of coastal structures. As the technique depends on making multiple radiocarbon measurements towards a single date, efficiency in application is the key and hence a number of practical considerations need to be taken into account in advance of conducting a dating program. This paper discusses some of these practical concerns and reviews them in the context of the intertidal crannogs in the Firth of Clyde on the west coast of Scotland.

Early medieval shellfish exploitation in Northwest Europe: investigations at the Sands of Forvie Shell Middens, Eastern Scotland, and the role of coastal resources in the First Millennium AD

ABSTRACT Coastal shell middens represent a well-known element of the archaeological record of island and coastal regions across the world and shellfish have been an important resource for subsistence since the mid Holocene. However, the factors that influence shellfishing remain poorly understood and in many regions investigations into the role of shellfish gathering often have remained focused on prehistoric examples to the detriment of shell middens of later dates. This article reports on the emerging evidence for large-scale exploitation of shellfish during a hitherto understudied period for shell midden archaeology in northwest Europe: the first millennium AD. The article includes a review of a series of previously unknown large mussel-dominated middens in eastern Scotland, an outline of their chronology and character, including Bayesian modeling of dates, and a synthesis of the emerging evidence for shellfish gathering in northwest Europe during the first millennium AD. The research represents the first investigation of large-scale early Medieval middens in Britain and the first review of their international parallels and the important new information they can provide for the early Medieval economy.
