The Organization of Later Stone Age Lithic Technology in the Caledon Valley, Southern Africa

Paleoclimatic data indicate that the Pleistocene/Holocene transition was a period of considerable ecological change in the Caledon Valley of the southern African interior. Stone artefact assemblages from sites in one part of this region, the Phutiatsana ea Thaba Bosiu (PTB) Basin of western Lesotho, were analyzed in order to investigate whether changes in settlement and subsistence strategies during this period are also reflected in the organization of lithic technologies. It appears that although technological solutions to the problems of subsistence risk may have been emphasized during the late Pleistocene, social means, such as exchange, dominated at the Pleistocene/Holocene boundary. Subsequent innovation or adoption of new formal tool types suggests that both strategies were important from the middle Holocene onwards.Dans la vallée de Caledon à l'intérieur sud-africain les données paléoclimatiques indiquent que la transition du pléistocène à l'holocène était une période de changement écologique considérable. Les résultats des analyses des outils lithiques découverts aux gisements dans une partie de cette région, le Bassin de la Phuthiatsana ea Thaba Bosiu (PTB) du Lesotho occidentale, sont présentées pour examiner si des changements aux stratégies de subsistance et de l'occupation des sites se réfletent à l'organisation des technologies lithiques. Il semble que on a employé les solutions technologiques pour éviter les risques de subsistance pendant le pléistocène tardif, mais que des solutions sociales, comme l'échange, prédominaient à la frontière pléistocène-holocène. L'innovation ou l'adoption plus tard des nouvelles outils lithiques suggère que tous les deux stratégies étaient importantes depuis le début du moyen Holocène.     

Late Classic Maya lithic production and exchange at Rio Bec and Calakmul,Mexico

Abstract

The organization of production and exchange of everyday lithic items is important in defining Classic period lowland Maya economic organization, but the current debate relies on the study of a few lithic workshops, whereas little is known about the consumers’ quotidian acquisition of everyday tools. I suggest looking at the problem from the point of view of the household and distinguishing local from nonlocal production by comparing experimental and quantitative data. Examination of the chert collections from households at Rio Bec and Calakmul enabled me to distinguish two different types of chert biface production and distribution during the Late Classic period (a.d. 650–800), namely by means of markets and itinerant craftsmen. Both sites had very different political organizations, but households from both cities acquired lithics through similar networks, showing that this particular aspect of the domestic economy probably had little to do with political power and centralization in the region.     

From Crafting to Caching: Technological and Iconographic Analyses of Blue Creek Cache 37

This paper presents technological and iconographic analyses of a Late Classic (a.d. 600–830) lithics cache recovered from the ancient Maya site of Blue Creek, Belize. The cache consisted of 21 obsidian prismatic blades and a number of chert artifacts, including 21 stemmed bifaces, a large laurel leaf biface, and a tridentate eccentric. The technological analysis of the stemmed bifaces identified three distinct stem production techniques that may be attributable to a combination of idiosyncratic knapping gestures and laterality, or handedness. A survey of Maya iconography demonstrated that large laurel-leaf bifaces and tridentate eccentrics occur in scenes depicting sacrifice and the burning of human remains, often by ritual specialists titled ch’ajoom, or “person of incense.” It is suggested that the presence of a large laurel-leaf biface and tridentate eccentric in the cache may indicate that Blue Creek was the residence of ch’ajoom at some point during the Late Classic period.     

Settlement networks and the organization of lithic tool production in the Late Prehistoric period (a.d. 1000–1780), Lower Nueces River Valley,South Texas

Abstract

Evidence from one of several Late Prehistoric settlement networks in the Lower Nueces River Valley in Texas demonstrates that base camps were surrounded by smaller-sized temporary camps. Local groups utilized nearby stone quarries, moved raw material to their settlements and reduced cores, preforms, and bifaces into tools for domestic use and portable toolkits. The Lower Nueces River Valley settlement organization and tool production during this period suggest restricted mobility, base camp sedentism, and abundant resource supply. This organizational structure promoted a complex foraging economy and perhaps the emergence of territorial clustering.     

Three Scenarios Of The Middle To Upper Paleolithic Transition The Middle to Upper Paleolithic Transition in Africa and the Early Peopling of Eurasia by Anatomically Modern Humans

Previous papers of this cycle describe the Middle to Upper Paleolithic transition in Eurasia and in the Sino-Malayan zone. Archaeological evidence from Africa however, suggests a completely different model of the transition. Despite the variability of Paleolithic industries in Africa, the maintenance of the Middle Paleolithic strategy of core reduction constitutes a common trend. The transitional industries in North and East Africa are characterized by Aterian points and backed geometric implements.     

On official corruption in the Yuan dynasty

The vicious cycle of official corruption got worse unprecedentedly in the Yuan dynasty (ca. 1279–1368). Corrupt officials at all levels from the local to the central governments were “extremely shameless and greedy.” Even many court ministers got involved in the vicious cycle of corruption. The top officialdom was polluted and degenerated badly because the Mongolian nobles made their “Sauqat” (taking gifts) tradition and the Semu, both official and merchant groups, took bribes as a way to amass wealth. Although the Mongol Yuan rulers did make a set of anti-corruption policies such as detailed rules of censorship and inspection relating to corruption crimes, these didn’t work well. Of all the reasons of the Yuan official corruption, the old Mongolian steppe traditions play the most important role, which formed the context for the low salary, improper selection and poor quality of the officials and of bending the law wrongly to pardon official misconduct. __________ Translated from: Nankai Xuebao Zhexue Shehui Kexue Ban 南开学报: 哲学社会科学版 (Nankai Journal, Philosophy and Social Science Edition), Vol.5, 2004, by Zhang Weiwei     

An integrated approach to reconstruct the role of the heat treatment within the reduction sequence of chert artefacts: The case of the early Neolithic site of Lugo di Grezzana (north-eastern Italy)

The lithic assemblage from the well-known site of Lugo di Grezzana (Italy) attributable to the Fiorano group (5,300–4,900 BC cal) is analysed to shed new insights on the early Neolithic lithic technology in North-Eastern Italy. Techno-typological data are discussed allowing detailed reconstruction of the reduction sequence, thanks also to several refittings. A complex laminar production with several technical objectives has been identified. Whereas clues for the heat treatment of lithic materials have been identified, we verified it by a combined experimental approach. In the first place, we used density measurements, which already proved to be useful for prescreening analysis, to detect potentially heated artefacts. Afterward, we performed Fourier Transform Infrared (FT-IR) spectroscopy tests to assess the actual (de)hydration condition of the siliceous materials. Reflectance spectra have been acquired, analysing any item and avoiding any constraint related to both morphology and thickness of the sample. The archaeometric results, combined with the reduction sequence reconstruction, provide new indications on the technical capabilities and knowledge of the human groups that inhabited the region during the early Neolithic.     

Prehistoric hunters and gatherers of Brazil

Although carbon-14 dates prior to 13,000 B.P. have been obtained from several sites east and south of Amazonia, their reliability is uncertain. By about 11,000 B.P., however, two lithic traditions were widespread. The Uruguai tradition, characterized by bifacial stemmed projectile points, was associated with open vegetation in the south; the Itaparica tradition, emphasizing well-formed unifacial artifacts, had dispersed over the eastern tropical parklands. An enormous amount and variety of rock paintings and/or engravings are associated with the latter. Around 7000 B.P., two new traditions emerged to exploit new habitats. The Humaitá tradition, characterized by large bifacial tools and an absence of stone projectile points, expanded over the broad-leaved forests in the south, leaving the open landscapes dominated by the projectile point-using Umbu tradition. The sambaqui (shell midden) tradition, also emphasizing large bifaces, developed along rugged portions of the southern coast. By 4000 B.P., groups along the coast of Rio de Janeiro and Espírito Santo were using domesticated or semidomesticated plants, perhaps sweet manioc. Maize was being grown in Minas Gerais by about 3500 B.P. Carbon-14 dates from numerous sites indicate, however, that the hunter-gatherer way of life persisted in many places long after the advent of pottery-making horticulturalists. The existence of large temporal and spatial gaps even in regions with considerable investigation makes it difficult to reconstruct the process of evolution reflected in these archaeological complexes. Correlations between cultural traditions and environmental fluctuations indicate, however, that adaptation to changing conditions was a significant challenge faced by prehistoric Brazilian populations.
