Ecological Patterns in the Upper Pleistocene and Holocene in the Jebel Gharbi, Northern Libya: Chronology, Climate and Human Occupation

Surveys and test excavations in the Jebel Gharbi have brought to light a large quantity of prehistoric sites indicating intensive human occupation from the Upper Pleistocene to the Holocene. Several radiometric dates (standard ¹⁴C, AMS and U/Th) provide a detailed framework of the absolute chronology of the local peopling of the area. Generalised Middle Stone Age archaeological materials represent the earliest term of reference in the geological series. Aterian complexes are well-represented, being widely spread throughout the mountain range and in the lowlands. Lower Later Stone Age, or “Dabban”, artefacts are also attested to both geological and archaeological sequences. Human occupation continued with the Upper and Final Epipalaeolithic (or “Iberomaurusian”) and later, with Capsian and Neolithic groups. Permanent and seasonal water springs and raw material sources influenced settlement strategy and selected areas offered particularly favourable conditions and became intensively occupied.     

Hunter–gatherer dispersals in the mammoth-steppe: technological provisioning and land-use in the Enisei River valley,south-central Siberia

Late Pleistocene Siberia was characterized by a unique mammoth-steppe biome. Two prevailing hypotheses exist to explain modern human dispersals in the Siberian mammoth-steppe. Upper Paleolithic human populations were either maintained continuously throughout the late Pleistocene or the peopling of this region resulted from multiple dispersal events. Past attempts at explaining the colonization process have resulted in culture-historical interpretations. This article uses lithic technological data from middle and late Upper Paleolithic sites in the Enisei River valley of south-central Siberia to explain human dispersals from a behavioral perspective. Technological provisioning and land-use strategies are reconstructed to help explain dispersal processes. Results of the study demonstrate that hunter–gatherers were using different adaptive strategies before and after the Last Glacial Maximum, indicating that multiple dispersal events shaped the peopling of Siberia.     

Assessing Prehispanic Herding Strategies through Stable Isotope Analysis: A Case Study from the Dry Puna of Argentina

ABSTRACT

The main goal of this work is to study the camelid herding and management strategies employed by the human groups that occupied the Dry Puna of Argentina during the late Holocene. Carbon and nitrogen stable isotope compositions were measured on bone collagen from domesticated South American camelids (llamas: Lama glama) recovered at two archaeological sites (Huirunpure and Chayal Cave). These results were interpreted using an already published data set of δ ¹³C and δ ¹⁵N values measured on bone collagen from modern herds of llamas managed in a traditional way. Our results showed that even though the archaeological sites of Huirunpure and Chayal Cave are located within different settings – at 4020 and 3700?masl respectively – and present different chronologies – 0–650 and 1300–1500 CE respectively – the llamas from both sites exhibit similar δ ¹³C and δ ¹⁵N values. This pattern was explained considering the characteristics of the vegetation communities that grow in the vicinity of both sites as well as the paleoenvironmental records of the Andean highlands. In sum, this work presents and discusses some preliminary results on the study of prehispanic herding practices in the Dry Puna of Argentina during the first 1500 years of the Common Era through stable isotope analysis.     

An Overview of Alaskan Late Pleistocene Archaeology: Historical Themes and Current Perspectives

Alaska has long held an important role in the late Pleistocene prehistory of the New World. Alaska being situated at the juncture between the Old and New Worlds, scholars have long looked to the Alaskan archaeological record to provide clues into the initial peopling of the New World. As such, Alaska figures prominently in most models of the peopling of the New World. In recent years, however, it has become clear that the late Pleistocene archaeological record of Alaska is characterized by great technological and adaptive diversity, and no single interpretive model can adequately explain that diversity. This paper traces the development of Pleistocene Alaskan archaeology by outlining the history of site discoveries and interpretations. In so doing, it provides a historical perspective on current frameworks of Alaskan Pleistocene prehistory. Based primarily on a search for the first inhabitants of the New World, however, the research questions traditionally guiding Alaskan archaeology have tended to complicate rather than clarify the picture. In some cases, this has led to false expectations and oftentimes contradictory interpretations, many of which still persist, and which can only be resolved by addressing the Alaskan record on its own terms.     

Carbon and nitrogen isotope composition of natural pastures in the dry Puna of Argentina: a baseline for the study of prehistoric herd management strategies

This study represents an isotopic survey of modern plants developed to establish baseline isotopic values in order to explore prehistoric herd management strategies employed by the South American camelid herders that occupied the southern Andean highlands during the past 3000 years. We present carbon (δ¹³C) and nitrogen (δ¹⁵N) isotopic compositions of natural pastures collected from different plant communities along an altitudinal gradient in the dry Puna of Argentina. Our results show that C₃ plants are the most abundant along the whole altitudinal gradient and that C₃ and C₄ plants exhibit a differential distribution, the latter being less abundant in those sites located above 3900?meters above sea level (masl). At the same time, plants growing at low-altitude sites with low water availability exhibit higher δ¹⁵N values than plants growing at high-altitude sites with higher water availability. These results explain the negative correlation found between altitude and South American camelid bone collagen δ¹³C and δ¹⁵N values published in previous studies. This work represents a fundamental step towards the building of an isotopic ecology for the dry Puna area with the ultimate goal to explore herd management strategies employed by human groups in the past. In this sense, modern plant and South American camelid tissue isotopic compositions would provide a frame of reference to interpret isotopic compositions measured on archaeofaunal remains recovered at pastoral sites, with the aim to explore mobility and pastureland use by prehistoric herders.     

Identifying palaeo-environments and changes in Aboriginal subsistence from dual-patterned faunal assemblages,south-western Australia

Palaeo-environments and past human subsistence patterns are difficult to determine from dual-patterned faunal assemblages where human and non-human predators have accumulated and intensively modified animal bones. This paper examines such records in the Leeuwin–Naturaliste Region of south-western Australia, where a thin belt of coastal limestone contains caves and rock shelters with rich faunal deposits. The Late Pleistocene and Holocene part of this record derives from four archaeological sites: Devil's Lair, Tunnel Cave, Witchcliffe Rock Shelter and Rainbow Cave. Correspondence analysis combined with cluster analysis enables a preliminary assessment of habitat changes using simple species abundances in the faunal assemblages and comparison with indices of past human activity in the sites and the species’ present habitat preferences. These inferred changes, consistent with previous analyses of faunal remains and tree charcoal, suggest that late Holocene sites document Aboriginal occupation in coastal heath, scrub and woodland. Late Pleistocene deposits record hinterland occupation at times of low sea-level when the coast was up to 30 km seawards of its present position and the surrounding vegetation was open-forest or woodland. As rainfall increased and vegetation changed in the Holocene, species foraging in open-woodland declined or became locally extinct, while species requiring closed canopy habitats increased. Rank-order correlations of taxa and archaeological remains from depositional sequences before and after the environmental change indicate that the occupiers of late Holocene sites favoured the same generalist species that occupiers of Late Pleistocene sites had favoured, which were available at all times. Prey habitats, foraging behaviours and historic records of ethnographic hunting and settlement pattern suggest that this local continuity is consistent with maintenance of a “dispersive mode” subsistence pattern in the region.     

The palaeogeography and Neolithic archaeology of Herm in the Channel Islands

Abstract

The small Channel Island of Herm combines several distinct habitats ranging from steep rocky coasts and a rolling upland plateau in the south to a dune-fringed sandy lowland in the north. Where upland and lowland meet, a line of megalithic tombs constitutes the island’s most striking archaeological feature. Four seasons of fieldwork (2008–2011) have sought to determine the environmental history of northern Herm since the last glacial period and to place the tombs within the broader context of Neolithic activity. A series of trenches and boreholes has revealed the changing morphology of the prehistoric land surface that lies buried beneath the extensive deposits of aeolian sand that cover this part of the island. Results indicate that much of the lowland plain was initially occupied by a shallow marine inlet that was cut off from the sea and progressively infilled starting in the 4th millennium b.c. Pollen and soil sequences reveal how the wooded early Holocene landscape around the edges of this inlet was steadily degraded by human impact and climate. Traces of settlement and cultivation (plowmarks) suggest the megalithic tombs were situated within an agricultural landscape. This finding has relevance for theories that have proposed that islands were favored places for burial by communities visiting from the neighboring mainland. Herm was a locus for settlement and farming as well as for burial during the Neolithic period.     

Submerged Paleoindian and Archaic Sites of the Big Bend,Florida

Abstract

The discovery and investigation of submerged prehistoric sites in the Big Bend region of the Gulf coast of NW Florida has revealed occupation ranging from the latest Pleistocene to the middle Holocene age. A summary of the local prehistoric record and the history of sea level rise are used to present the kinds of sites that may exist offshore and how far out on the continental shelf they might be discovered. A local paleoriver channel (the PaleoAucilla) has been traced offshore and parts of it have been surveyed for archaeological sites with excellent results. The local offshore environment is described, the history and methods of research are presented, and the results of selected analyses are briefly discussed.     

The impact of human activities on the natural environment of the Canary Islands (Spain) during the pre-Hispanic stage (3rd–2nd Century BC to 15th Century AD): an overview

Abstract

This paper presents a brief review of archaeological evidence for the impact of the pre-Hispanic population on the environment of the Canary Islands. Prior to human colonisation, the archipelago was an untouched environment with high botanical and faunal biodiversity. The first human settlement can be traced to the early 1st millennium BC; this period of settlement finished at the end of the 15th century AD when the Spanish Crown conquered the archipelago. It has often been assumed that the pre-Hispanic population had little significant impact on the islands' ecosystems. However, abundant evidence for faunal extinctions, deforestation and soil erosion has been recovered from archaeological sites across the islands. This indicates that pre-Hispanic colonisers introduced cultivated plants, opened up the forests to create fields and cut woody vegetation for fuel. They also introduced domestic animals and alien predators resulting in a major depletion of native fauna.     

Multi-Ethnic Settlement and Interregional Exchange in Pimampiro,Ecuador

Abstract

This paper reports on recent archaeological investigations at the sites of Shanshipampa and La Mesa in the Pimampiro district of northern Ecuador, a zone rich in archaeological resources about which relatively little is known. Within the context of Andean archaeology, this region is particularly significant insofar as it is described in early historic accounts as an important center of interregional trade. The role of trade in the shaping of ethnic identity and the evolution of complex societies has received relatively little attention in Andean scholarship. The present study expands our understanding of the modes, content, and significance of interregional interaction in the Andes by directing attention to the evidence for long-distance trade, trans-zonal connections, and multi-ethnic settlement in the northern highlands.     

Post-Pleistocene Archaeology and Geomorphological Processes on the Namib Desert Coast of South Western Africa

ABSTRACT

The Namib Desert coast is rich in potential food resources, but its extreme aridity imposed severe limits on human settlement in the past. It appears that intensive use of the coast began in the Middle Holocene, although there is evidence of intermittent occupation from the Middle Pleistocene. Coastal sites were closely linked to the desert interior and movement between the two was mainly via the linear oases of ephemeral river systems. Contact was at first sporadic but regular trade with merchant vessels was established in the mid-eighteenth century AD. Coastal geomorphological processes determined the location and accessibility of marine resources used by hunter-gatherer and nomadic pastoral communities. At the same time, marine, fluvial, and aeolian processes have influenced the visibility and survival of archaeological evidence on the coast.     

Paired Mississippian Communities in the Lower Ohio Hinterland of Southern Illinois

Abstract

Millstone Bluff and Hayes Creek are principal sites in a late Mississippian complex in the upper Bay Creek watershed in southern Illinois. These and other settlements represent a 13th century expansion of Mississippian settlement away from large stream valleys into remote interior locations. Although contemporaneous and very close to one another, these sites are very different and have a complex history. These two sites were explored in six seasons of excavation and here we summarize that work, focusing on commonalities and differences in architectural patterning and community structure. These reveal that the two sites appear to have varied as a function of nature of initial settlement, adherence to a village layout, and respective roles in the larger settlement system.     

New Data on South American Camelid Bone Size Changes during Middle‐Late Holocene Transition: Osteometry at Peñas Chicas 1.5 (Antofagasta de la Sierra,Argentinian Puna)

Approaching the study of camelid bone size change in the meridional portion of the South Central Andes is a significant subject especially when the assemblages are associated to radiocarbon dates placed at a time of social transition from an extractive to a producer economy. In this sense, this paper presents the results of applying osteometric techniques on a set of 10 elements from the Peñas Chicas 1.5 site dated around 3800 BP . The analysis shows the presence of at least three individuals, one of which corresponds to an Andean guanaco (Lama guanicoe) morphotype. The second and the third are similar in size to a modern llama (Lama glama) in their ‘intermediate’ and ‘cargo’ morphotypes. This is consistent with patterns already seen for sites from the Argentinian and Chilean Puna where the identification of larger individuals than the Andean guanaco modern standard shows the early stages of an increasingly bone size variability of South American camelids. This paper contributes with new data to understand the complex processes that occurred in the South Central Andes that led to the domestication of one of the most conspicuous animals in the archaeological record of the Argentinian Northwest.

Earliest hunters and gatherers of South America

Traditional syntheses of the archaeology of the late Pleistocene period in South America have focused primarily on the peopling of the continent by North American cultural groups and on identifying associations among regional sites. This focus has tended to ignore the widespread culture diversity of the period and the possible effects of different paleolandscapes on human migration and colonization, such as the presence of unglaciated tropical and temperate environments in the northern lowlands, the gateway to the interior. The earliest known cultural assemblages are characterized by various unifacial and bifacial lithic industries that may represent regional processes reminiscent of an Archaic lifeway. The major archaeological sites and associated artifact assemblages are examined in terms of regional and continental patterns of environmental and cultural change. Results suggest that the Pleistocene archaeological record of South America must be explained in its own terms and that the events and processes producing this record either occurred earlier than previously thought or are very different from those in North America.     

Living on the Edge? Transformation of a Marginal Pleistocene Landscape Into a Settlement Area in the Northeastern Part of the Netherlands

ABSTRACT

This paper will examine settlement location during the Iron Age in the northeast part of the Netherlands, an area shaped by Pleistocene geology. In recent years, a number of Late Iron Age/Early Roman settlements situated on the low lying slopes of sand ridges and nearby stream ridges revealed traces of an earlier Iron Age occupation. Palynological data revealed that this part of the landscape was used by humans before it was transformed into an area of settlement. An analysis of excavation data from two key sites at Denekamp-De Borchert and Groningen-Helpermaar, as well as other known sites, lead to the conclusion that the transformation of ‘peripheral landscapes’ into permanent settlement locations was preceded by a phase of arable cultivation which left no trace of permanent habitation. It is also suggested that the impact of human behaviour on the natural landscape in the Early and Middle Iron Age was much bigger than previously anticipated. When excavating this type of settlement areas dating to the Late Iron Age, archaeologists must be aware that only of a small group of archaeological features exist. The proposed model for the choice of settlement location may be more widespread, because of similarities in landscape between the study area presented here and other landscapes in Northwest-Europe (e.g. parts of Germany and Denmark).     

Deglaciation and Colonization: Pioneer Settlements in Northern Fennoscandia

We present new data on Early Mesolithic settlements in northern Sweden and discuss the process of pioneer colonization. A new set of radiocarbon dates from archaeological sites push deglaciation of northern Fennoscandia further back in time and demonstrate the rapid arrival of pioneer settlers. Environmental data reveal a highly productive early postglacial setting with plant communities unmatched in present ecosystems. The chronological and technological setting supports immigration from the north and northwest with pioneers relying on a long history of enculturating northern subarctic landscapes.     

Archaeological trends in the Southern Cone of South America

Current major research directions and findings in three areas of Southern Cone archaeology are discussed: (1) the entry of humans in Late Pleistocene times and early hunter-gatherer society, (2) the emergence of chiefdom societies, and (3) the Inca state. These themes are considered broadly in terms of local and interregional models of economic mobility and sociopolitical organization. Although emphasis is given primarily to the Andean regions of Argentina, Chile, and Bolivia, new studies and developments in the Argentinian Pampa and Patagonia are discussed.     

Farm mounds of the harstad area

The farm mounds of coastal North Norway are settlement accumulations produced by long period settlement on the same location. The majority seems to have come during medieval and later periods, but there are a few of early iron age origin.

There has been no total excavation of a farm mound, only minor trenches. This paper summarizes the efforts done on exploring the context and characteristics of farm mounds, based on surveys in one central part of North Norway, the Harstad area.

Questions like economical reconstruction and causes of accumulation are discussed.     

Reconstructing Prehistoric Population Movements: Seeking Congruence in Genetics,Linguistics, and Archaeology

Books discussed here focus upon the initial peopling of the Americas and the worldwide development of food production. They examine postulated historical instances in which genes, languages, and cultural elements appear to correlate, indicating major population movements in prehistory. Recognized experts in historical linguistics, archaeology, and molecular genetics review current methodology, available data, and models of global and regional population history. A more holistic approach and a greater understanding of human population dynamics are called for to improve our reconstruction of these past events.     

Prehistoric Investigations in Cantabrian Spain

Abstract

The rich Paleolithic record from Cantabrian Spain has long been interpreted in light of the phylogenetic, chronological scheme developed largely in the Périgord region of SW France, despite important differences in industries, environments, and faunas. This paper outlines the development of prehistoric research in Cantabria from its beginnings a century ago to the present, from the early work of establishing a regional chronology to the on-going attempts to understand and explain the changing regional adaptations of Pleistocene and early Post-Pleistocene hunter-gatherers. Cantabria is usually treated only in passing in syntheses of the prehistory of Western Europe, and its extensive literature is far less widely known than that of SW France. We hope in part to remedy the situation by providing a concise regional overview and an extensive bibliography of classic and modern references.

Preliminary conclusions from archaeological investigations and allied paleoenvironmental research by members of the La Riera Paleoecological Project are also discussed. The La Riera Project is an example of a modern, problem-oriented regional approach to the study of prehistoric human adaptation. It was designed to generate and test hypotheses about Late and Post-Pleistocene ecosystems in Cantabrian Spain. These hypotheses examine the relationships among habitat selection, site location, and climatic change, test for periodicity in prehistoric occupation, and examine patterns of covariance in artifact and faunal debris categories with the objective of isolating changes in adaptation recoverable from the 12,000 year record at the La Riera cave, and at other sites of comparable antiquity in the Cantabrian zone. Preliminary results define patterns of site-functional variation at La Riera related to prehistoric activity sets. These patterns appear to cut across the culture/stratigraphic units upon which much Upper Paleolithic research in western Europe is based.
