Is the Soanian techno-complex a Mode 1 or Mode 3 phenomenon? A morphometric assessment

The Soanian is traditionally seen as one of the major (non-Acheulean) Palaeolithic techno-complexes of the Indian subcontinent. Over several decades comparisons of Soanian assemblages have been made with the non-bifacial industries of East Asia and north-west Europe. The chronological status and typo-technological relationship(s) of the Soanian to other Palaeolithic industries have been the subject of much debate. When first named and described the Soanian was considered to contain evidence of Mode 3 Levallois-style core reduction. However, in recent years, the potential Mode 3 component of the Soanian has largely been ignored, and the techno-complex is described under various guises as a core/flake or ‘Mode 1’ techno-complex. Here, a comparative morphometric assessment of selected Soanian cores and other Palaeolithic nuclei is undertaken, to test the hypothesis that this industry contains a definite Mode 3 Levallois element. Discriminant Function Analyses (DFA) of morphometric variables provide robust evidence that at least part of the Soanian techno-complex contains Mode 3 Levallois cores. The implications of these analyses for the relationship between the Soanian and the Acheulean, and the relevance of the Soanian in considerations of the Movius Line are also discussed.     

An Early Palaeolithic site near Saiwan (Sultanate of Oman)

The Author describes a lithic assemblage attributable to the Early Palaeolithic, discovered in the winter of 1984–85 near Saiwan in central-eastern Oman. The chert assemblage, characterized by large-sized artefacts with plain, sloping, striking platform, various types of hand-axes, side scrapers and cores, is probably to be attributed to a late phase of the Acheulian Culture.     

Variability in bifacial technology at Elandsfontein,Western cape,South Africa: a geometric morphometric approach

This study applies a new three-dimensional measurement technique to determine the major source of variation in the Acheulian bifacial tool collection from the Middle Pleistocene site of Elandsfontein, South Africa. This three-dimensional technique is compared with conventional two-dimensional methods to investigate which methods capture morphological variation in the assemblage most comprehensively. Additionally, a set of experimentally produced bifacial tools are incorporated into the analyses to isolate the behavioral pattern underpinning identified variation in the archaeological assemblage. The interpretative breadth of current models explaining morphological variation in bifacial tools is then tested against the pattern identified in the Elandsfontein assemblage. Variation appears to be related to the consistent application of a specific reduction strategy associated with the early stages of bifacial tool manufacture. The intensity with which this strategy was applied seems to have been mediated by the availability of raw material that was suitable for the production of large bifacial tools.     

Archaeology of middle Pleistocene lacustrine and spring paleoenvironments in the Kapthurin Formation,Kenya

A number of key events occur in Africa during the middle Pleistocene including the disappearance of the Acheulian, the appearance of the Middle Stone Age, and the emergence of modern Homo sapiens. However, little is known about either the fossil or behavioral record for this critical time period. Excavation was undertaken at two middle Pleistocene archaeological sites, GnJh 42 and GnJh 50. These sites are located in close proximity to a large fresh water spring, a focal point on the landscape that supported a diverse plant and animal community. The lithic assemblages are dominated by flakes and cores, and lack all formal tools. However, the oldest evidence for systematic blade production can be found at these sites, indicating that important technological innovations were appearing at this time. Tendency to focus on the presence or absence of formal tools, means that assemblages of this age, lacking diagnostic artifacts, are typically subsumed within the Acheulian technocomplex. This practice disguises actual patterns of innovation and technological evolution. It is critical not to overlook this, as small-scale technological innovation allowed for more behavioral flexibility in response to rapid environmental change in a arid, mosaic environment.     

Shifts in Neandertal mobility,technology and subsistence strategies in western France

We propose a reassessment of Neandertal mobility strategies by crossing technological and zooarchaeological data. A broad comparative approach to the Middle Paleolithic series from western France shows that the Levallois and laminar flaking systems, the Mousterian of Acheulian Tradition (MTA) shaping system and the Quina and discoidal-denticulate flaking systems, vary significantly in terms of duration of reduction sequences, blank versatility and tool maintenance. These technological systems, which prevail in this context over different time periods, reflect distinct mobility strategies as a response to differing hunting practices. This new approach to Middle Paleolithic technologies and related mobility patterns gives new insights into Mousterian diversity. It also highlights the determinant role played by large game hunting strategies in the organization of late Neandertal societies.     

The Lower Acheulian site of Ambrona,Soria (Spain): ages derived from a combined ESR/U-series model

The Lower Paleolithic sites of Ambrona and Torralba (Soria, Spain) are often associated with each other because of their proximity although they do not represent the same morphostratigraphic unit. Systematic and extensive excavations were conducted at these sites by an American team during the 1960s and 1980s. Recently (1989–2000), a Spanish team has reactivated the research by initiating a new interdisciplinary project. In the central sector and west of the Ambrona site a stratigraphy has been established with six units from AS1 at the base to AS6 at the surface, corresponding to fluvial–lacustrine deposits in which abundant fauna associated with Acheulian artefacts were found. The most abundant species were elephant, horse, deer and aurochs. Other species like carnivores occur in small numbers only. The lithic assemblage is relatively sparse and consists of a few bifaces, choppers and several flake tools distributed throughout levels AS1 to AS5. The fauna and the lithic industry therefore document human presence at Ambrona during the Middle Pleistocene. In order to verify the presumed antiquity of the Ambrona deposits, horse teeth sampled in levels AS1, AS2 and AS6 were analysed using combined ESR/U-series (US) methods. The samples from the lower levels (AS1 and AS2) underwent a very recent uranium uptake as indicated by the U-series dates, ranging between 5 and 18 ka. In contrast, a more conventional postmortem uranium uptake was observed in the upper level samples (AS6) in the enamel and dentine tissues, while a light U-leaching was observed in the cementum. The combined ESR/U-series dates obtained on these samples suggest a minimum age of approximately 350 ka, contemporaneous of OSI 9 or the end of OSI 11, for the Ambrona site.     

A late Middle Stone Age artifact assemblage from Sibudu (KwaZulu-Natal): comparisons with the European Middle Paleolithic

It has been suggested that many behavioral innovations, said to appear during the late Middle Stone Age in sub-Saharan Africa, facilitated the expansion of anatomically modern humans from Africa and the Near East into Europe at about 50 kyr; the process eventually led to the replacement of Neanderthals by modern humans and the emergence of the Upper Paleolithic. However, assemblages in this time range are little known in South Africa. In fact, the transition from Middle to the Later Stone Age in Southern Africa is controversial. The early appearance in South Africa of many innovations, such as sophisticated knapping techniques (e.g. the use of soft hammer or indirect percussion in blade production, of composite tools, of microlithic and bladelet technologies) remains to be established through technological analysis.We present here the first results of a project designed to carry out detailed technological studies of several lithic assemblages in South Africa and France dated to the transition period. At this time we have completed the study of a post-Howiesons Poort assemblage from the rock shelter site of Sibudu.The >2 m deep stratigraphic sequence of Sibudu extends from Howiesons Poort at its base to final Middle Stone Age, directly under Iron Age layers. We have analyzed in detail layer RSP (ca. 53 kyr, 1 m above the Howiesons Poort levels) which has provided a large assemblage of several thousand stone artifacts. Compared to published MSA assemblages this industry is unusual for the very high proportions of retouched pieces (15%). The technology is not very elaborate and there is no strong standardization of the end-products. There are no flakes of predetermined shapes; retouch is used to modify irregular flakes to obtain desired edges. Knapping of flakes and blades is done by hard hammer; soft hammer is used only for retouching tools. Interestingly the older Howiesons Poort blades were produced on the same raw materials by soft hammer. Raw material (hornfels and dolerite) was procured from distances of less than 20 km. Unifacial points are the dominant type and there is strong evidence of hafting and use as spear armatures. Detailed comparisons with Middle Paleolithic assemblages of Western Europe show that the late Middle Stone Age technology in South Africa is very similar to that of the Middle Paleolithic; in fact we see no fundamental differences between the two entities, as far as lithic technology is concerned. Implications for the Out of Africa hypothesis are discussed.     

The limits of control: Technological agency,urban terrain,strategy and the state in the 2014 Gaza War

This article reassesses of the role of military technologies both in normative strategic thought and in the critical geopolitics literature by problematising their shared tendency towards representing the power of military technologies in a binary and sometimes hyperbolic way in relation to the complexity of terrain and the emergent intensity of war. In order to do so, it borrows theoretically from Object-Oriented-Ontology, using Harman's concept of “duomining” in dialogue with other understandings of material agency from assemblage theory and Actor-Network-Theory. This interstitial epistemology is applied to analyse the political implications for the State of Israel of its military's decisions on the use of weapons in urban warfare during the 2014 Gaza War. Through this framing, the paper argues that technological agency is ambivalent to the project of state stabilisation, and can act across spatial and temporal boundaries in ways unanticipated by political and strategic decisionmakers. It also demonstrates, counterintuitively, that technological objects can exercise agency as much by their absence as their presence in an event. These findings foreground the need for a more accurate accounting of what technological objects are, not just what they do, alongside a more nuanced consideration of the contingency of their power to shape politics in relation to the complex milieu of human and non-human factors that comprise geopolitical phenomena.     

Technological,Functional and Contextual Aspects of the K2 and Mapungubwe Worked Bone Industries

Mapungubwe (AD 1220–1290) is generally regarded as the first urban centre in southern Africa, functioning as the seat of power for an extensive but short-lived polity. More than 80 years of excavations here, and at its nearby predecessor K2 (c. AD 1000–1220), resulted in a substantial assemblage of material remains from elite and commoner contexts. This assemblage includes a large collection of worked bone objects, such as needles, awls, tubes and objects of personal adornment. Of particular interest are the bone arrowheads and link-shafts, of which a significant number of specimens were found complete and intact. Such quantities of well-preserved worked bone objects are unique in the archaeological record of the region. The worked bone assemblages from these two sites provide a rare opportunity to study multiple components of the production process as well as the use context of bone objects. In this paper, we characterise the K2 and Mapungubwe worked bone industries through various morphological, technological, use-trace and contextual approaches and discuss the significance of these aspects in terms of raw material selection and manufacture and archaeological use context. In particular, this study shows the complexity of these worked bone industries over time.     

Lithic Economy and Specialized Activities Among the Iberomaurusian Populations of Tamar Hat Rockshelter (Northeastern Algeria)

Tamar Hat rockshelter (Béjaïa, northeastern Algeria) has yielded a lithic assemblage showing general characteristics of an Iberomaurusian Early Late Stone Age nature. Specific “becs,” which we shall call “becs of Tamar Hat,” appear as an important component of the assemblage in the upper occupations, which occurred at the end of Late Glacial Maximum. These becs, from a technological point of view and especially by their shaping processes, constitute a reliable reference collection, though showing morphological variability resulting in part to the reduction process. The use-wear analysis conducted, based on a microscopic examination validated by experimentation, testifies the becs would have functioned for engraving hard bone, such as those of deer. Other scars observed on the sharp edge and lower face near the active portion of the tool are caused by hafting. Hence, the results of the technological and functional analyses of the becs from Tamar Hat reveal the presence of specialized activities in the upper occupations, related to the animal bone processing. These results are supported by the archaeozoological study, which confirms that the site functioned as a seasonal habitat, where Megacerin deer was exploited in the upper occupations for utilitarian, non-food purposes. The emergence of the use of the becs of Tamar Hat is synchronous with the end of the Upper Paleolithic, prior to the expansion of bec use in the Upper Magdalenian of Europe, where technical and stylistic convergences were observed. This raises the question of the emergence of these lithic implements in North Africa and the possible spread of similar industries elsewhere.     

THE TECHNOLOGICAL AND TYPOLOGICAL BEHAVIOUR OF A NEANDERTHAL GROUP FROM EL SIDRÓN CAVE (ASTURIAS,SPAIN)

This paper presents the first detailed analysis of the lithic industry from El Sidrón Cave. Previously we have published other works concerning Anthropology and Palaeogenetics. The lithic assemblage contains 415 artefacts coming from both unofficial and official excavations and is largely flake‐based. The raw material derives from the immediate cave environment, and is mostly chert, with quartzite in a lesser proportion. To date, 67 artefacts have been refitted, including some tools and cores. The spatial distribution of the refitted lithic artefacts confirms, on the one hand, the unity of the assemblage and, on the other, its secondary context.     

Levallois Lithic Technology from the Kapthurin Formation,Kenya: Acheulian Origin and Middle Stone Age Diversity

The earliest fossils of Homo sapiens are reported from in Africa in association with both late Acheulian and Middle Stone Age (MSA) artifacts. The relation between the origin of our species during the later Middle Pleistocene in Africa and the major archaeological shift marked by the Acheulian-MSA transition is therefore a key issue in human evolution, but it has thus far suffered from a lack of detailed comparison. Here we initiate an exploration of differences and similarities among Middle Pleistocene lithic traditions through examination of Levallois flake production from a sequence of Acheulian and MSA sites from the Kapthurin Formation of Kenya dated to ∼200–500 ka. Results suggest that MSA Levallois technology developed from local Acheulian antecedents, and support a mosaic pattern of lithic technological change across the Acheulian-MSA transition.Les premiers restes fossiles d’Homo sapiens sont rapportés d’Afrique aussi bien à des avec des outillages de l’Acheuléen final que du Middle Stone Age (MSA). La relation entre l’origine de notre espèce au Pléistocène moyen final d’Afrique et le changement majeur marquée par la transition Acheuléen-MSA est par conséquent un moment clé de l’évolution humaine qui a manqué jusqu’ici d’analyses comparatives détaillées. Nous nous proposons ici de commencer à explorer les différences et les similarités qui peuvent se faire jour au Pléistocène moyen dans les traditions techniques à l’examen des productions à éclats Levallois, dans une séquence de sites acheuléens et MSA de la formation de Kapthurin (Kenya), datée de 200–500 ka. Les resultants obtenus suggèrent que la technologie Levallois MSA s’est développée sur ce substrat acheuléen et renforce cette perception que l’on peut avoir d’une mosa?que de changements technologiques jalonnant la transition Acheuléen-MSA.     

Early Neolithic obsidians in Sardinia (Western Mediterranean): the Su Carroppu case

All the obsidians from the undisturbed Early Neolithic (Cardial ware phase I) layer of the Su Carroppu rock-shelter (Sardinia island) were studied. Their elemental composition and that of obsidians from the Monte Arci (Sardinia) volcanic complex was determined by ion beam analysis (PIXE). A comparison between the composition of Su Carroppu artefacts, analysed non-destructively, and that of Western Mediterranean analysed in the same conditions shows that the archaeological material belongs to the SA, SB2 and SC Monte Arci-types, to the exclusion of the SB1 type. The typological/technological study of this industry allowed us to reconstruct two chaînes opératoires, for the production of blades (using predominantly SC obsidians) and of flakes (based exclusively on SA and SB2 obsidians), respectively, but on the whole, assemblage blade/bladelet production was performed somewhat preferably with SA and SB2 types. Thus, in the earliest EN culture known on the island, ancient man had, for the making of its obsidian toolkit, a highly adaptive behaviour applied to the reduction of different useful obsidian sources.     

Hunting behavior and Neanderthal adaptability in the Late Pleistocene site of Pech-de-l'Azé I

The late Mousterian of Acheulian tradition (MTA) site of Pech-de-l'Azé 1 shows a very particular stratigraphic sequence characterized by numerous elements not usually found in Mousterian contexts such as avifauna exploitation and the use of hundreds of mineral pigments. Recent zooarchaeological and skeletochronological analyses provide new insights into the evolution of subsistence behaviors and settlement patterns of the Neanderthals that inhabited the shelter. Due to changes in hunting season, Neanderthals adapted their hunting strategies, exploiting various red deer populations which presented very different behavior. The evolution in the seasonal occupation of the shelter may have been the results of major modifications of its (series of roof collapsed) which induced a shrank in inhabitable space., which forced the Mousterians to adjust the way they used the cavity to its characteristics in order to optimize its exploitation. The conclusions underline the excellent adaptability of the Neanderthals to their physical environment.     

The Early Middle Pleistocene Site of Gombore II (Melka Kunture,Upper Awash,Ethiopia) and the Issue of Acheulean Bifacial Shaping Strategies

The Gombore II site dates to circa the Brunhes Matuyama Reversal and is one of the Acheulean localities of the Melka Kunture (Upper Awash, Ethiopia) archaeological complex, known since the 1970s. In 2001, this locality was selected as the site for an Open Air Museum and thus excavated. The excavation area has yielded an abundant Acheulean lithic assemblage manufactured on volcanic raw materials in close association with numerous paleontological remains. A technological analysis was carried out on a fraction of the bifacial tools (bifaces and cleavers) which could be temporarily removed from the displayed surface in the museum. This set of artefacts reveals new data about the bifacial shaping strategies adopted at the beginning of the Middle Pleistocene in Ethiopia. The use of obsidian and the systematic manufacturing of twisted bifaces are original features of the assemblage. These data are discussed in the framework of penecontemporaneous East African sites.     

Isenya: état des recherches sur un nouveau site acheuléen d'Afrique orientale

Résumé Isenya est le premier site acheuléen fouillé sur les hauts plateaux du Kenya. Sa richesse en vestiges lithiques et fauniques en fait dès maintenant un gisement important pour la connaissance des hominidés du Pléistocène moyen. Isenya est inclus dans un contexte sédimentaire fluviatile, indiquant que les hommes préhistoriques se sont installés sur une barre sableuse, le long d'une rivière qui était alors peut-être pérenne. La convergence des informations géologiques et archéologiques permet d'expliquer la mise en place des vestiges, la positionin situ de plusieurs niveaux d'occupation superposés, le faible degré de perturbation qu'ils ont subi, et l'origine essentiellement anthropique des associations os/pierres. L'industrie lithique est caractérisée par une grande abondance de bifaces et de hachereaux dont les proportions varient dans le temps. Une première analyse de l'ensemble apporte d'ores et déjà des indications sur les comportements techniques: les chaînes opératoires sont décryptées, depuis l'acquisition des matériaux jusqu'à l'obtention des outils. La faune associée à cet outillage est dominée par des animaux de savane ouverte (Alcelaphini etAntilopini). Son étude détaillée mettra en évidence les stratégies d'acquisition du gibier et son mode de consommation. Attirés, entre autres raisons, par la proximité de l'eau et des affleurements de phonolite, source principale de matière première pour l'outillage, les hominidés ont occupé cet enfroit de façon répétée dans un court laps de temps, selon une périodicité à rapprocher sans doute des comportements de subsistance.

Isenya is the first Acheulian site excavated in the Eastern Highlands of Kenya. Very rich lithic and faunal remains in a fluviatile sedimentary context indicate hominid activity on a sandy bar next to a river, which was perhaps perennial. Microstratigraphy and archaeological data permit reconstruction of the processes by which the remains were deposited. Severalin situ occupation layers show only a slight degree of perturbation. The bone assemblage is of anthropic origin, and the lithic industry is characterized by an abundance of bifacial pieces, level VI being particularly rich in cleavers. From the analysis of the lithic industry we can obtain some idea of hominid technological behaviour, most notably the operational chains of tool production from the procurement of raw materials to the knapping sequences. The fauna associated with the lithic materials is dominated by animals of the open savanna (Alcelaphini andAntilopini); and its detailed study will allow us to specify the strategies used in the procurement of game and its subsequent consumption. Without doubt, the reasons for hominid occupation at this particular site will be impossible to explain fully. However, choice of this location, where evidence for several different activities has been uncovered, should be considered in terms of the proximity both of water and of outcrops of phonolite, the principal raw material for tool-making. Repeated occupation by hominids over a short time may, perhaps, correspond to the periodicity of their subsistence behaviour.

     

A history of failed innovation: continuous cooking and the Soviet pulp industry, 1940s–1960s

Abstract

In the years before and after the Second World War, chemical and related industries in a variety of countries experienced a surge in innovation and development. As a result, the pulp industry became a space for considerable innovation. In Sweden, Johan Richter developed the Kamyr digester, a pulp cooker that could run continuously and was adopted by industry within a decade. Prior to Richter, Soviet engineer Leonid Zherebov designed a similar cooker. But after 25 years of experiments, Zherebov’s design failed, and Soviet factories began to produce pulp using imported Kamyr digesters. This article examines the history of continuous pulp cooking in the Soviet Union as a means to understand the nature of Russian technological innovation and its failures. The paper contends that his effort failed because of the technological system developed by Soviet forestry – a system characterized by a lack of open communication among its main institutional actors and a scarcity of resources to facilitate innovation.     

The Spanish telephone sector (1876-1924): A case of technological backwardness

This article explains the often neglected history of the Spanish telephone sector. Its main purpose is to examine the factors that determined the technological choices that were made in this sector, and to describe and analyze the growth of telephone networks in Spain and the rest of Europe between 1876 and 1924, a period marked by the internationalization of technology. It concludes that a complex range of factors, varying in their specific importance over the period, determined the pattern of technological diffusion in this sector. In the period dominated by Bell's patents, the sector was characterized by a high degree of technological homogeneity. However, once the licenses on these patents expired, a greater variety of technological devices were adopted in the sector, although this variety was limited by the control that the larger firms wielded over the market and policies of international cooperation. Spain, unable to keep pace with technological developments elsewhere in Europe, failed to establish its own national industry of telephone materials and equipment.
