SHIFTING SETTLEMENT PATTERNS IN THE SOUTHERN JORDAN VALLEY AND DESERT FRINGES OF SAMARIA DURING THE EARLY BRONZE AGE I PERIOD

Abstract

This study deals with the unprecedented settlement activity during the Early Bronze Age I that has been recently recorded in the Jordan Valley and the desert fringes of Samaria. The increase in the number of sites primarily characterises the latter part of the period (Early Bronze Age IB), and is accompanied by two other important phenomena: population inroads into new regions, and the first appearance of fortified sites. A profound crisis at the end of the period resulted in the almost complete abandonment of the valley sites and the concentration of settlement along the eastern foothills of Samaria.     

Aztec period houses and terraces at Calixtlahuaca: The changing morphology of a Mesoamerican hilltop urban center

Abstract

Calixtlahuaca, a Middle–Late Postclassic site in the Toluca Valley of central Mexico, was occupied ca. a.d. 1100–1530. Our excavations reveal some of the processes involved in the creation, functions, and decay of a large hilltop urban center. At its height, the majority of the site’s surface (264 ha) was covered with residential-agricultural terraces supported by a complex water management system. House construction techniques included the use of adobe brick, wattle-and-daub, and stone pavements. Our fieldwork contributes to a growing body of research on hilltop political capitals in Mesoamerica. Using a refined chronology, we illuminate the processes by which people constructed the residential zones of this ancient hilltop city.

Abstract

This article examines the development of urban forms of community organization on the north-central coast of Peru during the 1st millennium b.c. Recent mapping and excavations at the Early Horizon center of Caylán, in the Nepeña Valley, provide insights into the nucleation of human groups at an extensive valley floor complex. The results indicate the establishment of an urban core around cross-cutting avenues, while architectural data point towards the existence of multi-functional residential stone-and-mud walled compounds. The density of the architectural remains combined with the abundance of refuse is indicative of a significant urban population. The Caylán research sheds light on the development of urbanism after the demise of the Chavín sphere of interaction.     

Lead isotope analysis as a new method for identifying material culture belonging to the Vázquez de Coronado expedition

Archaeological evidence has become an increasingly important component of efforts to identify the route of the Francisco Vázquez de Coronado expedition through northern Mexico and the southwestern United States (1540-1542). Here, we report the first high-precision lead isotopic measurements of artifacts from two archaeological sites with strong material evidence for the expedition’s presence: Piedras Marcadas Pueblo in New Mexico and the Jimmy Owens Site in Texas. The analysis of lead and copper armaments from both sites reveals that many artifacts have overlapping or extremely similar isotopic ratios. We propose that the narrow range of lead isotopic ratios measured on these artifacts can be interpreted as a geochemical fingerprint for some of the Coronado expedition’s surviving material culture, and provides evidence that we interpret to suggest the expedition derived lead and copper metal from Mexican sources. Such a geochemical fingerprint presents an empirical method for discriminating between artifacts that belonged to the Coronado expedition and those related to subsequent Spanish, historical, or modern activity in the Southwest U.S. Thus, this method could significantly impact the search for and identification of archaeological sites associated with the Coronado expedition.     

Late Triassic palynoflora from the Pranhita–Godavari Valley,India: evidence from vertebrate coprolites

Vijaya, Prasad, G.V.R. & Singh, K., June, 2009. Late Triassic palynoflora from the Pranhita–Godavari Valley, India: evidence from vertebrate coprolites. Alcheringa 33, 91–111. ISSN 0311-5518.

The Upper Triassic Maleri Formation, represented by red clays and sandstones, has to date not produced any plant macrofossils or palynomorphs. Many spiral and non-spiral coprolites collected during this study from the Maleri Formation of the Pranhita-Godavari Valley were analysed for palynomorphs. Based on shape, nature of coiling and size, the Maleri coprolites are classified into seven groups. Of these, only Group-I, Type 5 (non-spiral) and amphipolar (spiral) types yielded diverse gymnospermous and pteridophytic spores, pollen, other plant debris and sparse fungal spores and algal remains. Occurrences of Antulsporites varigranulatus, Aratrisporites spp., Cadargasporites baculatus, Dubrajisporites isolatus, Enzonalasporites vigens, Foraminisporis coelatus, Grandispora spinosa, Kraeuselisporites saeptatus, Polycingulatisporites reduncus, Staurosaccites spp., Tethysispora unica and Tikisporites balmei confirm a Late Triassic age for the coprolite-bearing red clays. Records of Classopollis classoides and Callialasporites turbatus/dampieri in these assemblages more precisely suggest a Norian to Rhaetian age. The non-spiral coprolites were possibly produced by aquatic piscivorous animals whereas the spiral coprolites may have been produced by an as yet unidentified fish taxon. The coprolite-producing animals (spiral and non-spiral groups) possibly ingested gymnospermous and pteridophytic plant remains passively along with water or their herbivorous prey.     

Cultural transmission, copying errors, and the generation of variation in material culture and the archaeological record

Archaeologists are adept at analyzing variation in artifacts. The discipline has well established and tested methods to track change through time and to evaluate the function of artifacts that depend upon measures of variation in the archaeological record. Although a critical concept, the means by which variation in material culture is generated is not well understood. This paper explores one source of variation, copying errors, and systematically examines how cultural transmission processes act to amplify, reduce, or maintain such variation. Using simple models, we generate expected distributions for the amount of variation that occurs through time under varying circumstances. This variation is caused by small errors that are transmitted from one person to another in the propagation and replication of cultural traits. These baseline values provide useful null models for explaining variation in prehistoric assemblages of artifacts. We use measurements of projectile points from Owens Valley and Woodland ceramics from Illinois to demonstrate the value of this approach.     

Cultural Origins of the Egyptian Neolithic and Predynastic: An Evaluation of the Evidence from the Dakhleh Oasis (South Central Egypt)

The debate surrounding the origins of the Egyptian Neolithic and Predynastic has, over the past few decades, come to rest on the neighboring Saharan region as the most likely source of influence. Although there is some evidence for the appearance of domesticates in the Western Desert before food-producing communities emerged in Upper and Lower Egypt, there is a strong case for the introduction of Saharan artifacts and technologies to the Nile Valley communities. This paper examines this argument in relation to the Western Desert region of the Dakhleh Oasis (South Central Egypt). The intent of the paper is to recognize the role Dakhleh played in the cultural development of the Egyptian Neolithic and Predynastic and whether this can clearly be seen through artifact parallels. Les parties débattant des origines de l'Egypte néolithique et pré-dynastique ont fini, au cours des dernières décennies, par conclure que la région voisine du Sahara était leur source d'influence la plus vraisemblable. Bien que certaines preuves existent de l'apparition de plantes et d'animaux domestiques dans le Désert occidental avant l'émergence de communautés produisant des aliments en Basse et Haute Egypte, de solides arguments émergent en faveur de l'introduction d'objets fabriqués et de technologies dans les communautés de la Vallée du Nil. L'exposé en question examine cet argument par rapport à la région du Désert occidental de l'Oasis de Dakhla (centre-sud de l'Egypte). Le but de cet exposé est de reconnaître le rôle de Dakhla dans le développement culturel de l'Egypte néolithique et pré-dynastique et de déterminer si oui ou non celui-ci peut clairement être identifié, de façon parallèle, au travers d'objets fabriqués.     

Maps,Mapping, Modernity: Art and Cartography in the Twentieth Century

While the history of cartography has freed itself from debilitating debates over the scientific and artistic status of maps, considerations of the relationship between art and cartography have continued to focus largely on pre‐modern maps, avoiding critical examination of twentieth‐century art and science in cartography and leaving intact the impression that these followed distinct paths in the modern period. In this paper, however, I have drawn on theoretical work in Science Studies and taken account of modern art's separation from aesthetics to suggest that an examination of art and cartography in the twentieth century should focus on mapping practices rather than on maps as such. A summary overview of modern‐art movements and selected works indicates a continued, if critical, engagement of avant‐garde artists with cartography, and the examination of more popular newspaper artwork produced in the context of the intensely modern visual culture of mid‐twentieth century Los Angeles indicates a similarly close connection between modernity, art and cartography.     

Getting “Out of Africa”: Sea Crossings,Land Crossings and Culture in the Hominin Migrations

Palaeoanthropologists and archaeologists have advanced a wide range of explanatory narratives for the various movements of Homo erectus/Homo ergaster, and the first modern Homo sapiens, “Out of Africa”—or even back again. The application of Occam's razor—a parsimonious approach to causes—gives a more cautious approach. There is nothing in the available evidence that would require the ability for a human water crossing from Africa before the later Pleistocene, whether across the Strait of Gibraltar, the Sicilian Channel or the southern Red Sea (Bab el-Mandab). A parsimonious narrative is consistent with movements across the Sinai peninsula. The continuous arid zone from northern Africa to western Asia allowed both occupation and transit during wet phases of the Pleistocene; there is no requirement for a “sponge” model of absorption followed by expulsion of human groups. The Nile Valley as a possible transit route from East Africa has a geological chronology that could fit well much current evidence for the timing of human migration. The limited spatial and temporal opportunities for movements “Out of Africa,” or back again, also puts particular difficulties in the way of the gene flow required for the multiregional hypothesis of the development of modern Homo sapiens.     

Evidence for Interaction from Recent Hunter-Gatherer Sites in the Caledon Valley

Evidence for contact between hunter-gatherers and agropastoralists from excavated sites in a well-documented frontier zone in the eastern Free State, South Africa, reveals varied intensities of interaction. These interactions range from clientship to relative autonomy. Comparison between recent (eighteenth- to early twentieth-century) hunter-gatherer occupations of rock shelters in the Caledon Valley also suggests that a variety of social relationships between hunter-gatherers and farmers, known ethnographically, occurred simultaneously.
