Rocks are heavy: transport costs and Paleoarchaic quarry behavior in the Great Basin

Central place foraging models are used to investigate assemblage variability at two Paleoarchaic (terminal Pleistocene/early Holocene) dacite quarries in the central and eastern Great Basin. Our analyses focus specifically on biface reduction and how varying degrees of reduction relate to the costs of transporting the resulting products upon departing the quarry. Our results suggest that when the distance to be traveled to a residential base is great, reduction will proceed further at the quarry than if the residential base is fairly close. Further, a residential site assemblage will consist of bifaces at later stages of reduction than its associated quarry.

The social selectivity of migration flows affecting Britain's larger conurbations: An analysis of the 1991 census regional migration tables

Little is known about the social composition of migration affecting British cities, despite the currently high political salience of this issue. This is principally because of the very limited availability of reliable city‐scale data on such migrant characteristics as occupation and income. This paper uses the Regional Migration Tables from the 1991 Census to document the migration of labour force members to and from Britain's larger conurbations, distinguishing six main Social Groups defined on the basis of occupation. It is found that all eight areas were net losers of economically active people, that all six Social Groups were generally contributing to these net losses and that, in every case except London, there was a strong positive relationship between social status and the rate of net out‐migration to the rest of Britain. This latter case suggests the need for further work, which would benefit from the more detailed migration datasets that are promised from the 2001 Census.     

Commentary. The Diseases of Alexander the Great

The accompanying articles that speculate that Alexander the Great had a traumatic carotid dissection or congenital cervical scoliosis demonstrate the difficulties in retrospective diagnosis as a historical enterprise. The extant primary sources were written centuries after Alexander’s death and are ambiguous in their original languages, and even more so in translation. Thus we cannot be certain what illness Alexander actually had. Furthermore, anachronistic diagnosis removes Alexander from the medical context of this time, telling us little of historical significance about him. Such investigations also illustrate the more general limits that the absence of context imposes on the study of ancient history.     

The Greek-Albanian Archaeological Project on Maligrad: Shaping the Cultural Heritage in the Tri-National Zone of the Great Prespa Lake

Abstract

This paper aims to analyse the collaboration of the Greek-Albanian Archaeological Expedition with the local community of the tri-national district (FYROM-Greece-Albania) of the Great Prespa Lake, in South-eastern Albania, conducted by the Institute for the Transbalkanic Cultural Cooperation (Greece) and the Institute of Archaeology of Tirana (Albania). It is argued that local cultural heritage, including the heritage of the archaeological past, can play a significant reconciliatory role in an extremely delicate national and environmental landscape throughout the work of all the bipolar participants: locals and ‘foreign experts’.     

Archaeobotanical evidence of prehistoric maize (Zea mays) consumption at the northern edge of the Great Plains

Analysis of starch granules, phytoliths, and plant macrofossils from archaeological features and carbonized food residue provides important new insight into the extent of prehistoric maize (Zea mays) consumption on the North American Great Plains. These data suggest that consumption of maize, and probably other cultigens, was widespread on the eastern Canadian Prairies between approximately AD 1000 and 1600. Domesticated plants may have been grown locally, acquired through trade, or transported into the region following dispersal of family groups from horticultural villages located elsewhere. However, the lack of strong artifactual evidence of gardening, and the small-scale nature of sites on the eastern Canadian Prairies indicate that local horticulture, if practiced, was non-intensive.     

The technology of Stone Age colonization: an empirical,regional-scale examination of Clovis unifacial stone tool reduction,allometry, and edge angle from the North American Lower Great Lakes region

There is now broad consensus that the appearance of Clovis in Northeastern North America (Great Lakes, New England) represents a colonization pulse into recently deglaciated landscapes. Due to the increased resource uncertainty that comes with colonizing unfamiliar landscapes, it was hypothesized that the majority tool component of Clovis assemblages, unifacial stone tools, should have been knapped on tool blanks possessing the design properties of longevity and functional flexibility to facilitate exploration mobility and guard against the absence of toolstone sources in the new landscape. These properties are optimized by large, flat flakes, possessing large surface area relative to flake thickness. Since discarded and, at times, exhausted unifacial stone tools do not preserve the original dimensions of the blank upon which they were created – necessary items for a true test of blank morphology selection – this study presents a set of predictions for inferring whether Clovis unifacial stone tool blanks were selected for the properties of longevity and functional flexibility based on evidence that Clovis people actually capitalized on those properties. Due to the nature of Clovis unifacial stone tools, tool size was of necessity used as a proxy for tool reduction, on the grounds that smaller tools are more likely to have been resharpened than larger tools, at least in the case of unifacial flake tools. The results showed that less resharpened tools possessed flatter, less spherical shapes than the more resharpened tools, which possessed more globular, spherical shapes, suggesting Clovis foragers exploited the retouch potential afforded by the larger, flatter blanks. Edge angles showed no relationship with tool reduction, suggesting that Clovis foragers exploited the functional flexibility afforded by flatter blanks by adjusting the edge angle to be either higher or lower as needed. These results are consistent with the notion that human colonizers, who did not know the abundance or location of stone outcrops prior to settling an unfamiliar territory, not only “geared up” before leaving a stone source, but geared up as efficiently as possible by carefully selecting the blanks they chose to carry. Broader implications for such careful unifacial stone tool blank selection are discussed.

Middle Holocene Taphonomy and Paleozoology at the Prairie-Forest Border,the Itasca Bison Site,MN

The Itasca Bison site near the prairie-forest border in central Minnesota is important to understanding the cultural and ecological role of bison in the upper Midwest during the middle Holocene. Recent reanalyses of this assemblage support the original interpretation of a taphonomically complex, fluvially modified site. Despite this taphonmic complexity, the role of humans in the butchering and possible accumulation of some of the bison fauna is also supported, although not as the only mechanism of accumulation. The bison assemblage is slightly biased toward males, and seasonality estimates are spread throughout the year. New direct accelerator mass spectrometry dates indicate a minimum of two highly mixed depositional events: one at 7970–7790 cal B.P. and an earlier event between 8520 and 8180 cal B.P.
