During archaeological excavations, artefacts are collected, tagged and stored. Based on these, archaeologists interpret peoples’ social identity, relations and even world view. However, a narrow range of ‘natural objects’ are also collected, often if perceived as essentially different from the surrounding gravel or debris ; that is, if odd or beautiful enough to the excavator. Fossilised Sea-urchins ( Echinoidea ) are such objects and have been recovered from hunter-gatherer-fisher coastal sites dated to Mesolithic and Neolithic. They are predominantly found in refuse layers and floor contexts. In this brief article, based on finds of fossils at recent excavations in Rogaland county, Norway, the fossils are considered as illustrative of the fluidity and transformability of life in a Mesolithic ontology that avoids the separation of nature and culture. Hence, life is stone, and stone is life. Contrasting this is the archaeological practice of separating ‘cultural’ from ‘natural’. Does this limit our understanding of life in the Stone Age ?
Major changes in lithic technologies are often explained by either migration or crisis. Here we argue that continuity and minor adjustments in lithic production can tell equally dramatic tales of altered social situations. We base our interpretations on identified lithic blade production concepts and raw materials at 30 sites dating 7500–5000BC, i.e. from before and after the massive Storegga tsunami hit the coast of western South-Norway around 6150BC. Regional continuation, but also local variations in lithic production are interpreted inspired by a machine-oriented ontological framework. The tsunami disrupts the environment, society and its lithic traditions are affected. Although no immediate major breaks are observed, sometime after the tsunami, societies or lithic production as 'machines' in separate regions had begun to hum to different tunes. We suggest that variation in tsunami impact had created differing local social contexts which in turn pushed the lithic traditions down diverging paths.
<p>Around 8200 years ago, the Storegga tsunami, caused by a massive submarine landslide off the coast of Central Norway, struck the coasts of west Norway, Scotland and Doggerland. This event is well known from wide ranging geological and palaeobotanical work undertaken over the last 30 years. What has been less explored, however, is the potential social impact that this natural freak event had on the Mesolithic hunter-gatherer societies living on the coasts and shores of the North Sea. What happened in the tsunami&#8217;s aftermath? It has been widely assumed to have been a disaster &#8211; but was it? What constituted a disaster in the Mesolithic? In the Mesolithic, people were hunter-gatherer-fishers, they lived by, off, and with the sea. Settlement sites in West Norway were concentrated along the outer coast. People lived on the shores of islands and headlands, or along resource rich tidal currents. Eastern Scottish Mesolithic sites are also found on contemporary coasts, while the coasts of central Doggerland have long since become submerged. What happened to groups in these landscapes on the day the sea became a monster and in the years that followed? In this paper, we will outline a newly started project that will investigate the social impact of the tsunami in areas of the North Sea that have distinctive Mesolithic histories. These coastal inhabitants had, for millennia, developed their own traditions to engage with and learn how to exploit and keep safe from the sea. What can we learn about Mesolithic societies by investigating how communities handled the forces of a tsunami? Responses identified in the archaeological material and environmental archives can potentially inform us of social structures, institutions or ways of living that made the existing societies resilient or vulnerable.</p>
Abstract In this article, we critically review recurrent tropes, implicit frameworks, and unexplained concepts in current research on the process of “Neolithisation” in the western part of southern Norway. Two models are on offer, as also seen elsewhere in the European research: either 1) the transition to agriculture is rapid and substantially carried by migrants, or 2) the Late Neolithic transition builds on a long history of local adaptation. After outlining these models, we scrutinise especially west Norwegian evidence, pointing out ambiguities and limitations in the material which mean that neither of the two models fit. In the final section, we consider which new questions could be asked to move beyond the current, somewhat polarised debate: Who are the actors of the transition, how are boundaries between groups created, and can the acknowledgement of the complexity of the process of ‘migration’ result in new narratives? Addressing these questions remains a fundamental challenge for archaeological migration studies as a whole.
The Storegga tsunami (c. 8150 cal BP) is geologically well attested from various isolation basins across the west Norwegian coast. Ascertaining the impact it had upon the Mesolithic peoples who lived through it, however, remains a difficult proposition; one further complicated by broadly synchronic processes of climate change and sea-level rise. This paper presents a regional scale approach to addressing this matter through a multiproxy study comprising: 1) the performance of a new numerical tsunami run-up simulation for six different focus areas; 2) characterising the impact of the tsunami upon key resource base ecosystems; 3) characterising the potential for complication arising from contemporaneous processes of environmental change caused by the '8.2 ka BP event', and sea-level rise associated with the early-mid Holocene 'Tapes' transgression, and 4) the reconstruction of temporal traditions in site location relative to the contemporary palaeoshoreline within the six focus areas used for the numerical simulation. Severity of run-up and inundation is found to be acutely variable according to coastal geomorphology and topography, bathymetry, and proximity to the propagation centre. Although the tsunami may have had a severely negative impact upon some coastal inhabitants and ecosystems, it is not possible from current evidence to reliably infer unequivocal impacts relating to the tsunami through the archaeological record, nor is it clear that impact upon key ecosystem components was necessarily lasting, widespread, or even entirely negative for coastal hunter-fisher-gatherers. Variability in projected run-up and settlement histories highlight the appeal of regionally based approaches to reconstructing impact, at least where data resolution may permit. The tsunami does not appear to have prompted a lasting shift away from coastally oriented ways of life.
The application of high-resolution imagery from unmanned aerial vehicles (UAV) to classify the spatial extent and morphological character of ground and polished stone tool production at quarry sites in the Shetland Islands is explored in this paper. These sites are manifest as dense concentrations of felsite and artefacts clearly visible on the surface of the landscape. Supervised classification techniques are applied to map material extents in detail, while a topological analysis of surface rugosity derived from an image-based modelling (IBM) generated high-resolution elevation model is used to remotely assess the size and morphology of the material. While the approach is unable to directly characterize felsite as debitage, it successfully captured size and morphology, key indicators of archaeological activity. It is proposed that the classification of red, green and blue (RGB) imagery and rugosity analysis derived from IBM from UAV collected photographs can remotely provide data on stone quarrying processes and can act as an invaluable decision support tool for more detailed targeted field characterisation, especially on large sites where material is spread over wide areas. It is suggested that while often available, approaches like this are largely under-utilized, and there is considerable added value to be gained from a more in-depth study of UAV imagery and derived datasets.
