Economic and environmental changes during the 4th and 3rd millennia BC: the 25th Jubilee Symposium of the AEA in Bad Buchau,southern Germany

Abstract

This study represents the first detailed published analysis of a relatively large archaeologically derived faunal assemblage in eastern Beringia for the Late Pleistocene/Early Holocene. The faunal remains, dated to 10,100 cal. BP, are well preserved and have highly resolved spatial association with lithics and hearth features. Factors in the formation of the assemblage are assessed through analyses of weathering, presence/absence of carnivore damage, fragmentation patterns, bone density, and economic utility. Taphonomic analyses indicate that human transport and processing decisions were the major agents responsible for assemblage formation. A spatial model of wapiti and bison carcass processing at this site is proposed detailing faunal trajectories from the kill sites, introduction on site in a central staging area to peripheral marrow extraction areas associated with hearths and lithic items. Data from mortality profiles, spatial analysis, and economic analysis are used to interpret general economy and site function within this period in Interior Alaska. These data and intersite comparisons demonstrate that considerable economic variability existed during the Early Holocene, from broad spectrum foraging to efficient, specialized terrestrial large mammal hunting.     

Fremont Hunting and Resource Intensification in the Eastern Great Basin

Empirical tests of resource-intensification models argue for diminishing foraging efficiency among hunter–gatherers in California over the past 2000 years (Basgall, 1987,Research in Economic Anthropology9,21–52; Broughton, 1994aJournal of Archaeological Science21,501–514; 1994bJournal of Anthropological Anthropology13, 371–401). The evidence for this long-term trajectory consists of decreases in the abundance of large, high-ranked prey in archaeofaunal assemblages. This paper presents faunal data from Fremont structural sites in the eastern Great Basin and Northern Colorado Plateau as an additional empirical test of resource intensification patterns and compares them to trends in California and the American Southwest. The measure of resource efficiency used is the artiodactyl index (following Broughton, 1994ab), a tool derived from prey choice models of optimal foraging. Faunal data from Fremont structural sites argue that (1) foraging efficiency declined during the Fremont period, and (2) this decline was due to population growth.     

FOCUS: The Scapula Representation could be the Key: A Further Contribution to the ‘Klasies Pattern’ Debate

Past discussion on the unusual skeletal part representations at Klasies River Mouth is briefly summarized. Recent discussion in this journal, regarding the “Klasies Pattern”, has focused upon the differential destruction of small and large bovid bone epiphyses by carnivore ravaging and density-mediated attrition. Bartram & Marean (1999) argue, from ethnoarchaeological study and consideration of other archaeological sites, that, unless shaft fragments are painstakingly identified, the upper limb bone epiphyses of large bovids will be seriously under-represented. They therefore suggest that the “Klasies Pattern” is likely to be artefact of taphonomic and analytical processes. Klein, Cruz-Uribe & Milo (1999) replied with a defence of the analytical procedures employed during the original Klasies River Mouth analysis. They also state that there was very little evidence of carnivore ravaging at Klasies River Mouth. In this paper, it is pointed out that Bartram & Marean's (1999) study only considered the humerus, radius, femur, tibia and metapodia. However, in the “Klasies Pattern” it is the scapula that is most notably abundant in the small bovid classes and most notably scarce in the large bovid classes. It is argued that, from the study of bone mineral densities and Brain's (1981) carnivore ravaging experiment, there is no reason to expect a differentially greater taphonomic destruction of large bovid scapulae. In fact, exactly the reverse may be true. It is therefore argued that at least this aspect of the “Klasies Pattern” must be considered to represent human differential bone transport, rather than an artefact of taphonomic processes.     

Bone Modifications Resulting from Captive Chimpanzee Mastication: Implications for the Interpretation of Pliocene Archaeological Faunas

In order to obtain chimpanzee (Pan troglodytes) mastication damage on bones, cleaned, disarticulated ribs and long bones of bovids and cervids were coated with food substances found palatable by captive chimpanzees. The bones were then presented to four groups of mixed sex and mixed age chimpanzees from the Tulsa Zoo (Oklahoma) and the Southwest Foundation for Biomedical Research (San Antonio, Texas). In the process of feeding on the coated bones, the chimpanzees inflicted discernible mastication damage on 73·61% of the total recovered bone specimens. Analysis of these chimpanzee-induced bone modifications reveals that non-technological hominoids of the same approximate size and with comparable dentition and bite force to the gracile australopithecines and earliestHomoare very capable of inflicting the same range and degree of damage to bones as are feeding carnivores. This finding implies that zooarchaeologists must take a contextual (configurational) approach when analysing mastication damage on arch-aeological bones, rather than automatically attributing all such damage to carnivores.     

STATISTICAL ASPECTS OF POTTERY QUANTIFICATION FOR THE DATING OF SOME ARCHAEOLOGICAL CONTEXTS*

This paper describes some statistical analyses of a particular archaeological material (pottery) originating at some sites in the city of Tours. An important part of the archaeological study of pottery is the comparison of ceramic assemblages to establish the absolute dates of contexts. In this paper, a statistical model is built to assess this comparison. The statistical procedure uses classical tools (correspondence analysis, linear regression and resampling methods) in an iterative scheme. Archaeologists may find in the paper a useful set of known statistical methods, while statisticians can learn a method of ‘arranging’ well‐known techniques. No method is new, but their combination is characteristic of this application.     

CORRESPONDENCE AND DISCRIMINANT ANALYSES OF SAND AND SAND TEMPER COMPOSITIONS,TONTO BASIN,ARIZONA*

Geologists use petrographic modal analysis to relate fluvial sand composition to source rock composition, thus establishing provenance. Archaeologists seeking to establish provenance of sand temper in pottery can use similar petrographic methods, but their finer scale of investigation requires more precise statistical tools than those employed by geologists. A quantitative method for performing that task is presented. It utilizes correspondence analysis and discriminant analysis of logratio transformed point‐count data to define petrofacies, or sand temper resource procurement zones. The procedure is illustrated with sand and sand‐tempered sherd samples collected from the Tonto Basin, central Arizona; temporal trends in utilitarian ceramic production c. AD 100–1350 are reviewed.     

COMPOSITIONAL CHARACTERIZATION OF FRENCH LIMESTONE: A NEW TOOL FOR ART HISTORIANS*

Limestone from quarries known to medieval craftsmen and from the monuments they built and embellished, as well as from carvings now in museum collections, has been characterized by neutron activation analysis. Specimens from 38 quarries in the Lutetian and Jurassic limestone formations of France and from sculptures in American and French museums have been tested, and the results have been compiled in a data base to which art historians may refer when attempting to determine provenance for sculptures. Multivariate statistical analysis of concentration data shows stone from a particular quarry in the Paris basin to be compositionally homogeneous and distinguishable from other quarries in the same formation. The same approach to data related to quarries near the Burgundian abbey of Cluny finds general agreement between classifications based on compositional and on petrographic data, but the number of samples available for analysis at the time of writing was insufficient to achieve the finer distinctions reported for the Paris basin.     

GC–MS ANALYSIS AND FATTY ACID RATIOS OF ARCHAEOLOGICAL POTSHERDS FROM THE WESTERN GREAT BASIN OF NORTH AMERICA*

The study of organic residues in archaeological pottery has focused on fatty acids due to their relative stability and longevity. However, even these compounds are subject to degradation, which makes assignment of residues to original foods problematic. This paper suggests that the use of ratios of fatty acids that degrade at roughly the same rate can be useful to identify very general categories of foods. It compares independent information on pot function based on ethnography and engineering/technological studies to that reconstructed based on extracted fatty acid ratios. The results support the notion that Great Basin pots were used primarily to boil seeds and that pot shape and pot function were related.     

The Preservation and Identification of Piñon Resins by GC‐MS in Pottery from the Western Great Basin

Gas chromatography — mass spectrometry analysis of a sherd from the Nevada Test Site revealed a high quantity of terpenes, including sesquiterpenoids and diterpenoids, demonstrating that piñon resins were prepared in the pot in prehistoric times. The presence of these biomarkers allowed for a very specific identification of the products prepared in the pot, a level of detail not often achieved in lipid residue analysis. That the terpenes are relatively unoxidized demonstrates that they are quite stable over long periods of time. The study also shows that sherds on the surface of archaeological sites can preserve lipids and terpenes and are amenable to organic residue analysis.     

NEUTRON ACTIVATION ANALYSIS OF SIXTEENTH- AND SEVENTEENTH-CENTURY EUROPEAN BLUE GLASS TRADE BEADS FROM THE EASTERN GREAT LAKES AREA OF NORTH AMERICA*

Sixteenth- and seventeenth-century European blue glass trade beads from aboriginal sites in the eastern Great Lakes area of North America have been analysed non-destructively using low neutron dose instrumental neutron activation analysis, so that the beads could be returned to their keepers. Dark blue (cobalt-coloured) beads are readily separable from turquoise (copper-coloured) beads. Differences in the chemistries of the turquoise blue beads appear to be useful in separating glass beads from the two centuries. Low calcium, sixteenth-century turquoise beads tend to distintegrate by a leaching of the alkali metals.     

CHARACTERIZATION OF NATURAL PRODUCTS ON NATIVE AMERICAN ARCHAEOLOGICAL AND ETHNOGRAPHIC MATERIALS FROM THE GREAT BASIN REGION,U.S.A.: A PRELIMINARY STUDY

Although documentary evidence provided by ethnographers makes reference to the source of adhesives, sealants, dyestuffs and medicines used by the communities of the Great Basin, much of it is sporadic and unspecified. However, observations of amorphous deposits surviving on stone tools, ceramics, basketry and wooden artefacts have prompted an investigation of their identity, procurement and use. The aim initially is to study samples from a number of archaeological and ethnographic contexts from the region. Comparative material includes higher plant and insect resins. The study provides a unique opportunity to document use patterns in plant and animal resources in the Great Basin region.     

How Did Mississippians Prepare Maize? The Application of Compound‐Specific Carbon Isotope Analysis to Absorbed Pottery Residues From Several Mississippi Valley Sites

A newly developed compound‐specific stable carbon isotope technique allows the detection of maize in absorbed organic pottery residues. This method was applied to absorbed organic residues from a variety of Mississippi Valley potsherds, and successfully identified maize components. Maize was cooked in sampled vessels less often than expected, but otherwise fitted expected patterns of maize use derived from stable carbon isotope analysis of human bone from the region. Absorbed organic pottery residue analysis is useful in determining pottery use, particularly in concert with other analytical methods.     

MICROCHEMICAL CHARACTERIZATION OF BUILDING STONE FROM SEVILLE CATHEDRAL,SPAIN

Enrichment diagrams for trace elements have been proposed as a useful and straightforward procedure to identify ores and stones. The identification of the diverse stone of the exterior of the Cathedral of Seville has been achieved by this means. Fourteen trace elements have been analysed, from both quarry and building material samples, using atomic absorption and flame emission spectrometry in order to apply enrichment diagrams for identification purposes.     

A PROVENANCE STUDY OF POTTERY FROM ARCHAEOLOGICAL SITES NEAR CANOSA,PUGLIA (ITALY)*

Studies have been carried out to assess the provenance of selected pottery excavated at archaeological sites near Canosa, Puglia (Italy). Sixty-six sherds, ranging in date from the mid-seventh century BC to the beginning of the third century BC, were analysed by atomic absorption spectroscopy and 16 elements were determined. The analysis data were subjected to multivariate classification procedures. Tests showed that the majority of the examined sherds came from ancient local kilns; a probable Ionian origin was established for some other sherds, while the rest were of unknown origin.     

Revisiting the Exploitable Threshold Model: 14th century resource procurement and landscape dynamics on Perry Mesa,Arizona

Abstract

This study presents a revision of Dean E. Arnold’s (1985, 1993) Exploitable Threshold Model, which attempts to explain the selection of raw materials for pottery production. Arnold’s model posits that potters’ preferences for materials are largely determined by the linear distance to individual resources. We argue, however, that potters’ choices are, at least in part, determined by spatial relationships among the necessary resources rather than the distances to them. This study of 14th century pottery production on Perry Mesa, Arizona demonstrates that potters selected materials based on the co-occurrence of readily available sources of temper, clay, and fuel. Lack of water and fuel sources on the mesa top compelled local residents to eschew the use of readily available basaltic sands to temper their plainware pottery. Instead, Perry Mesa potters selected granitic sands from the river valley nearly 300 vertical meters below their settlements.     

PROVENANCE STUDIES OF ROMAN AFRICAN RED SLIP WARE USING NEUTRON ACTIVATION ANALYSIS

African Red Slip ware (ARS) from Carthage and San Sisto Vecchio (Rome) was analysed by neutron activation analysis. The Carthage tableware was linked with Oudna and the type 1 lamps were probably from a northern ARS/lamp factory other than the sources currently investigated. Two samples were central Tunisian, probably manufactured at El Ala. The San Sisto samples divided into three groups and three outliers of undetermined provenance. Group 1 was central Tunisian, probably from El Ala, and was composed entirely of terra sigillata chiara C forms. Group 2 was of unknown origin within northern Tunisia. Group 3 was the largest subset and most of its constituent samples were associated with El Mahrine. Additionally, four samples were linked with Oudna.     

ARTIFICIAL NEURAL NETWORKS AS A TOOL FOR ARCHAEOLOGICAL DATA ANALYSIS*

Artificial neural networks (ANN) offer a supplement to traditional classification algorithms applied to archaeological data. Because of their flexible architecture, non-linearity and independence from the distribution of the underlying data, neural networks have unique advantages for such applications. In particular, ANN models are well suited for use with the sparse data sets common in archaeological work. Combining multivariate techniques with networks for data validation, pre-processing and classification exploits the merits of both and provides a comprehensive approach to the analysis and classification of archaeological data.
