Geochemical impacts to prehistoric iron-rich siliceous artifacts in the nearshore coastal zone

In the Middle Atlantic region of the United States, landscapes drowned by sea level rise contain scores of prehistoric archaeological sites. These sites provide archaeologists with a rare opportunity to investigate various geologic processes. During the transition from a terrestrial to an offshore setting, the materials associated with an archaeological site are exposed to a series of geochemical processes inherent to the formation of tidal marsh. The duration of the geochemical exposure to tidal marsh is largely dependent on the rate of marine transgression. Here we describe the stages associated with the sulfidization and sulfuricization scheme and the impact to iron-rich lithic artifacts from naturally drowned archaeological sites. Sulfidization and sulfuricization should also impact buried archaeological materials as a result of anthropogenic dredge spoil dumping and the creation of man-made tidal marshes along modern coastlines. Our results indicate that the surfaces of an iron-rich artifact, as well as its interior are visually and geochemically altered by prolonged exposure to the anaerobic conditions of a tidal marsh. Not only should researchers be cautious about making lithic material identification on artifacts found within coastal tidal marsh areas, but museum curators should be aware of the damaging impact of long-term aerobic storage. The geochemical tidal marsh scheme that has altered or corroded iron-rich lithic artifacts in the nearshore zone is an expression of a process that has impacted numerous earlier prehistoric sites currently located on the continental shelf or beneath the coastal estuaries around the world.     

The Paleolithic of Dzungaria (Xinjiang,Northwest China) Based on Materials from the Luotuoshi Site

The paper reports the results of an analysis of surface collections of artifacts made at the Luotuoshi site in Dzungaria, Xinjiang, northwest China. The site was discovered in 2004 by a joint Chinese-Russian-American archaeological expedition. A techno-typological analysis of the artifacts was carried out noting aeolian abrasion of the artifacts’ surfaces. This technocomplex is quite homogenous and is characterized by a combination of Levallois-like and subprismatic blade-based reduction techniques. Analogs of the Luotuoshi assemblage have been identified within the lithic industries of the Altai, the Orkhon-1 and Tolbor-4 sites in Mongolia, and at Shuidonggou in the Ningxia Hui Autonomous Region in China, all of which have been attributed to the Early Upper Paleolithic. Luotuoshi is the first site associated with the blade-based Early Upper Paleolithic discovered in northwest China and its particular features make it possible to correlate this technocomplex with those from southern Siberia and northern Central Asia.     

Discoveries of Neolithic prehistoric sites at Pleistocene carbonate rock shelters on the east coast of the UAE

Three newly discovered prehistoric sites on the east coast of the United Emirates (UAE) are described. All are located on surfaces of Pleistocene carbonates or rock shelters that are generally rare along the eastern coast of the Gulf of Oman. Aqqah 1 (Le Meridien al Aqqah Beach Resort), the most important and best preserved of these sites, is a partially collapsed rock shelter with an exposed section, lithic finds and marine molluscs. Deriving an exact date from the material present is difficult because of a lack of comparanda. A bifacial fletched arrowhead made of yellow jasper and the lithic debris of five different raw materials as well as an undecorated ceramic fragment might suggest a date in the Late Neolithic or Early Bronze Age. The presence of many marine bivalves and snails with operculae, which differ from recent coastal species, indicates the collection and consumption of living molluscs by the prehistoric population of Aqqah. Nearby burials may be related to the rock shelters.     

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.     

Migration as an explanatory concept in paleolithic archaeology

Migration is frequently invoked as an explanation for pattern in paleolithic archaeology but the credibility of doing so depends almost exclusively upon acceptance of an analogy between historical process and the processes that have combined to create an ancient archaeological record. It is argued here that paleolithic archaeology cannot be treated as an extension of history and that historical processes are therefore inappropriate analogies for the site formation processes manifest in Upper Pleistocene archaeological contexts. The credibility accorded migration as an explanatory concept varies from one national or regional research tradition to the next. Why this should be so is examined in a discussion of the paradigm concept and how it affects construals of the nature and meaning of pattern.     

Stone Tool Research at the End of the Millennium: Classification, Function, and Behavior

This is the second of the two papers that review the literature of archaeological lithic analysis over the last decade. This paper concentrates on aspects of stone tool research that are not directly related to the production or procurement of the tools themselves. It is divided into classification, functional analyses, behavioral processes, and approaches to the subject currently popular among analysts. As with the previous paper, an attempt has been made to be as comprehensive as is reasonable, though availability of sources has resulted in an emphasis on North American literature.     

Late Pleistocene Technology at Rose Cottage Cave: A Search for Modern Behavior in an MSA Context

Recent excavations at Rose Cottage Cave, located in the Free State, South Africa, have revealed both a transitional assemblage, dated to ca. 20,000 bp, and a final Middle Stone Age (MSA) assemblage, dated to ca. 28,000 bp. Preliminary analysis of these assemblages was undertaken to determine if the current European model of a cultural revolution for the emergence of the Upper Palaeolithic can be applied to the southern African evidence. Examination of these assemblages revealed that differences occurred between the transition in Europe and that in southern Africa in both the chronology of the transition and the degree to which this complete cultural package is linked to the emergence of Late Stone Age (LSA) technology. The methods of lithic production, the chronology of the MSA/LSA transition, and the associated behavioral characteristics were examined and results indicated that the technological change which occurred during the MSA/LSA transition was not a dramatic innovation in technology but, rather, a shift in the emphasis of production from a level of technology already in place and demonstrate a level of continuity between the MSA and the LSA. As a gradual occurrence, the MSA/LSA transition does not seem to fit the time frame for the European Upper Palaeolithic; it both occurs at a later period and takes longer to transpire. In addition, the origins of symbolic use of lithics appear to lie within the MSA, indicating that a more complex set of behavioral adaptation was occurring in the late Pleistocene in southern Africa, and that the MSA/LSA transition in this region does not adequately conform to the model of a revolutionary shift in behavior and technology that is proposed for the Middle/Upper Palaeolithic transition in Europe     

Technological Change and Economy in the Epipalaeolithic: Assessing the Shift from Early to Middle Epipalaeolithic at Kharaneh IV

Epipalaeolithic hunter-gatherer communities in the Southern Levant exhibit numerous complex trends that suggest that the transition to the Neolithic was patchy and protracted. This paper explores the changing nature of occupation at the Epipalaeolithic site Kharaneh IV, Jordan, through an in-depth analysis of the lithic and faunal assemblages. Focusing on the analysis of a single deep sounding (unit AS42), we address how Kharaneh IV occupations link to the local landscape and environmental changes. As an aggregation site, Kharaneh IV represents an interesting locale to explore the changing nature of aggregation and social cohesion prior to the origins of agriculture, as well as changes in technology and subsistence between the Early and Middle Epipalaeolithic. We explore the tempo and nature of transition from one archaeological culture to the next through changes in technology and how this reflects the people making and using tools, to understand how foragers adapted to a changing landscape.     

A Russian Before and After the Revolution: P. P. Efimenko,a Pioneer of Levantine Prehistoric Research

ABSTRACT

This paper offers a reappraisal of the Levantine prehistoric chronological sequence constructed by Pyotr Petrovich Efimenko (1884–1969). As a young Russian prehistorian, Efimenko visited Palestine in 1913, collected material from several sites and, in 1915, published a synthesis in which he compared the prehistory of Europe with that of the Near East. This was part of his comprehensive monograph on the Prehistory of Eurasia which was also based on his work at the sites of Mezin and Kostenki and the Palaeolithic of Russia. The current paper also attempts to evaluate the career of Efimenko particularly in light of the unfamiliarity of his work among prehistorians working in the southern Levant.     

The Europeanization of Prehispanic tradition: Bernardino de Sahagún’s transformation of Aztec priests (tlamacazque) into classical wise men (tlamatinime)

The Nahua wise men known as tlamatinime have been treated as core figures of Prehispanic indigenous culture in Mexico. Most scholars, basing their opinions heavily on the works of Bernardino de Sahagún (Historia general de las cosas de Nueva España, Coloquios y doctrina cristiana, and the Florentine Codex) portraying the tlamatinime as scholars, philosophers, scribes, poets, and physicians who reflected the advanced and highly civilized nature of Prehispanic Mexico. However, in this article, I argue that in their search for indigenous intellectuals, scholars have overlooked one of Bernardino de Sahagún's pet projects: ‘taming’ or domesticating Aztec religious authorities, turning them from threatening shaman-like figures into misguided but otherwise professional teachers, thinkers, and public speakers, thereby stripping them of their religious authority.
