This paper focuses on the controversy surrounding the chronological interpretation of two subdivisions of a North African Epipaleolithic culture: Typical Capsian and Upper Capsian. Although originally defined as two evolutionary phases on the basis of stratigraphy, since the development of absolute dating methods they have been considered as contemporaneous. A new approach to the lithic technology of collections from the classic sites of Bortal Fakher, El-Mekta, Relilaï, and Aïn Dokkara allows us to redefine the industry and the traditional chronology. A wide-reaching comparison including major Capsian sites, and based on cultural attribution, chronology, and lithic technology, supports our preliminary results. Around 8000 B.P., a technological change occurred, corresponding with an environmental shift, and calls into question the contemporaneity of Typical and Upper Capsian. The causes, mechanisms, and implications of this technological change are integrated into a broader discussion leading to more questions about the way of life of the makers of the Capsian, their cultural evolution, and their persistence as hunter-gatherers in a Neolithic world. 相似文献

A new classification system is proposed to describe the volumetric formats of clastic lithic products of geological and archaeological origin. In order to build this operative classification, the rectangular block or cuboid is established as the standard geometric format to represent their three‐dimensional format (the X‐axis being length or long diameter, the Y‐axis being the width or intermediate diameter, and the Z‐axis being the thickness or short diameter) on a two‐dimensional diagram. To obtain this graph, each absolute coordinate (X, Y, Z) defining the prisms is projected on to an auxiliary plane with a new set of relative coordinates (x, y, z), expressed as the percentage of their sum. The projection generates a triangular diagram on which the indices of elongation and flatness are represented. A geometric transformation converting the triangular diagram into a quadrangular diagram has been produced in order to better represent the scatter points. Then, a double scale is necessary: (i) an absolute scale to quantify the indices, and (ii) a relative scale to calculate where the graphic locus is projected. This new graph also allows us to work with statistical parameters. Finally, two classic examples of applications selected from the literature are shown. 相似文献

In north-western Patagonia, obsidian was used during the entire Holocene, and its importance increased with time. Recent fieldwork discovered a new obsidian source located in the Río Grande, which was called ‘Coche Quemado' (CQ). The results indicate that the CQ source has a different geochemical signal than all other sources in the region. Its use is spatially restricted to piedmont and, to a lesser extent, the plains. Chronologically, CQ was exploited in the middle and late Holocene, and its use accounts for a range of spatial distribution between 150 and 200 km. 相似文献

This paper compares the quantification of different raw materials in a chipped stone assemblage by weight and by number at the site of Brno-Štýřice III in Moravia, Czech Republic. The use of the same reduction technology for all raw materials means that the Brno-Štýřice III assemblage is a good case study. The result demonstrates that semi-local raw material tends to dominate numerically, but in terms of weight, there is a significant change in the predominant raw material. The paper contextualizes the results in relation to other assemblages and discusses the possible reasons for this phenomenon. 相似文献

Hedmark County is a large inland district in southeast Norway that represents the southern part of the Sámi settlement area, and a Sámi–Norse borderland. Centred on the municipalities Rendalen and Engerdal, the study investigates the long-term cultural and social processes involved in the construction and maintenance of a borderland using theories of ethnicity and cultural tradition. Over time, different groups of people have used the diverse landscapes, and two periods are highlighted: the Late Neolithic and the Bronze Age (2350–500 BC), and the Iron Age and the Middle Ages (500 BC–AD 1500). The focus is on how different groups of people used the landscapes as seen through variation in settlement, subsistence, borders and contact networks with neighbouring and distant regions. 相似文献

We present experimental data examining the energetics and identification of axial bipolar reduction in contexts of lithic miniaturization on milky quartz. These experiments answer two specific questions. First, does bipolar reduction provide any benefits over freehand reduction? Second, can axial bipolar reduction be distinguished from freehand reduction? Our data show that bipolar reduction requires significantly less time to reduce a percentage unit of core mass and to produce a millimeter of cutting edge on milky quartz than freehand reduction. Milky quartz bipolar reduction surpasses even the cutting edge production efficiency of obsidian pressure blades. We outline a series of quantitative criteria for identifying bipolar cores and flakes. Our results show that bipolar cores and flakes can be distinguished from those produced using freehand reduction by quantifying platform crushing, distal flake rebound scars, bulb shearing, as well as axial, bipolar, and splintered flake terminations. Our results challenge the widely held perceptions about the wastefulness of bipolar reduction and provide clear guidelines for identifying this reduction strategy in archaeological milky quartz assemblages. 相似文献

Late Postclassic period (a.d. 1350–1525) Tarascan economic activities often included higher degrees of political involvement and territorial control compared with other ancient Mesoamerican societies. Here I examine Tarascan obsidian economies through an analysis of lithic production and consumption patterns from structures excavated on and near the Great Platform at the imperial capital of Tzintzuntzan. Four spatially distinct patterns are evident. Great Platform residents used high-quality obsidian blades as ceremonial items or burial offerings and scrapers for craft production. Lower elite residents of Structure F, outside the Great Platform, produced their own blade tools and consumed a higher percentage of green obsidian than residents of the Great Platform. Excavations at Yacata 3 recovered bifacial arrowheads and obsidian bloodletters associated with disturbed offerings. The spatial distributions of lapidary preforms and highly polished fragments combined with accounts from the Relación de Michoacán (a.d. 1541) suggest that lower elites produced obsidian jewelry near the Great Platform. 相似文献

Two stone flakes partly covered in birch-bark-tar and a third without tar on it were discovered in fluvial gravel and clay in central Italy, in association with the bones of a young adult female Elephas (Palaeoloxondon) antiquus and several micromammals. The probable chronology of the stone flakes is compatible with the late Middle Pleistocene suggested by the site's small mammals and geological context. The fauna indicates a cool stadial episode before isotope stage 6. That age means the flakes are the oldest ever found hafted with tar and indicate a greater capacity for late Middle Pleistocene hominins to utilize raw materials available during cold phases. 相似文献
