Evaluating protein residues on Gainey phase Paleoindian stone tools

Blood protein analysis provides a method for acquiring and interpreting archaeological data bearing on human–animal relationships. The present study makes use of cross-over immunoelectrophoresis (CIEP) and a large sample of stone tools (N = 130) from an early Paleoindian site pertaining to the Gainey phase (ca. 11,200 BP) of the Midwestern USA. Results are used to interpret toolkit organization and site structure, and indicate that hafted tools with longer use-life potentialities are more likely to be associated with preserved residues than are tools of a more ad hoc or situational character. Protein residues derived from cervids are the largest category of identified samples, a result consistent with an interpretation that these animals were important first-line resources of Gainey phase populations. The identification of caribou (Rangifer sp.) is notable. Interpretations of subsistence importance, however, must be tempered by an appreciation of the possible confounding effects of tool manufacture and maintenance in early Paleoindian contexts.     

On stone-boiling technology in the Upper Paleolithic: behavioral implications from an Early Magdalenian hearth in El Mirón Cave,Cantabria, Spain

Stone boiling is one of the principal cooking methods used by hunter-gatherer societies. The present paper proposes behavioral and organizational inferences as to how stone boiling was incorporated into hunter-gatherer subsistence practices through an examination of a shallow-basin hearth in an Early Magdalenian level (c. 15,500 ¹⁴C B.P.) of El Mirón Cave, Cantabria (northern Spain). Exploratory analysis of spatial patterns of archaeological remains (bones, lithic artifacts, and fire-cracked rocks) and use-life analysis of fire-cracked rocks demonstrate that the hearth was used and maintained during visits of humans who preyed mainly on ibex and red deer near the site. The relative accessibility of these ungulates and cost-induced technology of stone boiling suggest the implication that stone boiling was employed to maximize the energy and nutrition obtained from carcasses of these game taxa under the circumstance of resource intensification.     

Identifying domestic functional areas. Chemical analysis of floor sediments at the Classical-Hellenistic settlement at Düzen Tepe (SW Turkey)

For over a decade, multi-element chemical analysis of floor sediments in archaeological contexts has been a tool to identify and interpret anthropogenic chemical residues and activities. For the current study, a multi-element chemical analysis was applied to floor samples from a Classical-Hellenistic courtyard building at Düzen Tepe (SW Turkey). Among a series of 19 elements analyzed, K, Mg, Fe, P and Sr are thought to directly reflect anthropogenic chemical residues. The elements Cr, Mg, Ni, Pb and Ti are considered to reflect the geological background of the site, yet their contents seem to vary over different chemical residue zones, making them a suitable tool for delineating activity areas. Overall, the sampling and analysis techniques applied at Düzen Tepe – mild acid sample extraction and ICP-OES analysis – have proven to be fit for this kind of study. The analyses allow human activity zones within the study area to be identified and interpreted and deliver insights into the archaeological contexts that could not be obtained by archaeological research alone.     

Maize and Bone: Residues of Grinding in Northwestern Argentina*

Archaeometric and archaeobotanical analyses of grinding residues inside an archaeological milling stone tool from the Cueva de los Corrales 1 site in northwestern Argentina are shown. Multiple analytical techniques are used to identify ground substances, and their results are compared and complemented. They give direct and reliable evidence of maize (Zea mays L.) and burned bone grinding in the pre‐hispanic Argentine north‐west, although the latter is little related to milling tasks.     

Wooly mammoth mass accumulation next to the Paleolithic Yana RHS site,Arctic Siberia: its geology,age, and relation to past human activity

In 2001, the Yana RHS archaeological site was discovered in the lower Yana river valley, Arctic Siberia. Its radiocarbon age is about 28 000 BP. While enormous amount of Pleistocene mammal bones was excavated from the site, the mammoth bones occurred at an unexpectedly low frequency. That was interpreted as an indication of the limited role of mammoths in the subsistence economy of the Pleistocene Yana people. In 2008, next to the excavation local ivory miners opened a mass accumulation of mammoth accompanied by the artifacts. About one thousand mammoth bones from at least 26 individuals, and few wooly rhinoceros, bison, horse, reindeer, and bear bones have been unearthed there. Stratigraphy and radiocarbon dating provide evidence for cultural layer of Yana RHS and the mass accumulation of mammoth to be coeval. The geology and taphonomy of Yana mass accumulation of mammoth indicate its anthropogenic nature. Discovery of the anthropogenic mass accumulation of mammoth next to the Yana site suggests a greater role of mammoth in the subsistence practices of the Pleistocene Yana people than previously thought.     

Identifying activity areas in archaeological soils from a colonial Virginia house lot using phytolith analysis and soil chemistry

Environmental archaeology methods can uncover both house lot organization and economic adaptation practices when applied systematically in conjunction with traditional archaeological research. This is the first study to employ both phytolith analysis and soil chemistry to interpret activity areas on an archaeological site. The patterning in the phytolith and soil chemistry analyses from the site of Rich Neck Plantation, Williamsburg, Virginia, reveals a set of six activity areas in and around the 17th century house lot, demonstrating a degree of economic diversification generally attributed only to 18th century colonial economic and social transformations.     

δ18O Analyses of the Humpbacked Conch (Gibberulus gibberulus): Evaluating a Proxy for Reconstructing Sea-Surface Temperature at Chelechol ra Orrak,Palau

ABSTRACT

In Palau, Micronesia, marine resources, particularly shellfish, played a vital role in human subsistence for millennia. Despite the vast array of molluscan species in archaeological assemblages, there is a dearth of data on nearshore palaeoecology or prehistoric shellfish foraging practices. In this study, we analysed stable oxygen isotopes (δ¹⁸O) values present in the calcium carbonate shell of Gibberulus gibberulus from the Chelechol ra Orrak archaeological site to reconstruct average nearshore sea-surface temperatures (SST) from approximately 1500–1100 cal BP. Modern shellfish samples and environmental data were collected from intertidal zones near the site and x-ray diffraction (XRD) was employed to identify the biomineralogical composition of G. gibberulus. These steps provide necessary information for the selection of the proper oxygen isotope-to-SST conversion formula. The selected formula was applied to δ¹⁸O samples from archaeological shells to reconstruct prehistoric SST averages. The results of this proxy validation study verify that G. gibberulus accurately records ambient SST and can be used to reconstruct ancient nearshore conditions. These findings also contribute to the establishment of an environmental baseline, which can be used to examine how environmental changes may have influenced the availability of molluscan taxa that in turn influenced human subsistence practices through time.     

Historic landscape management: a validation of quantitative soil thin-section analyses

The archaeological interpretation of past land management practices can be greatly enhanced through examination of soil thin sections. Features relating to manuring practice are among those key to interpreting agricultural practices. The sources and the processes leading to the distribution of these manure materials may further improve knowledge of the past landscape utilisation. The use of quantitative analyses to examine soil thin sections opens the possibility of considering these relationships between manured areas in greater detail and to extract more subtle spatial and temporal changes in past management. In this study the validation of this methodology has been tested with quantitative image analysis methods used to examine manure inputs to a well-documented historical landscape of Papa Stour, Shetland, where intensive manuring has been practised until the 1960s. By using both historic and ethnographic evidence to validate the image analysis protocol, differences in spatial and temporal distribution are examined for the practices of manuring with both fuel residues and with turf. The validation of the hypotheses expected from ethnographic and historical data that quantitative soils-based evidence allows the definition of variations in manuring strategies and provides a more secure basis from which to interpret manuring management strategies in archaeological landscapes.

Identifying Threshing Floors in the Archaeological Record: A Test Case at Iron Age Tel Megiddo,Israel

Abstract

The identification of activity areas in archaeological sites is an important part of archaeological research contributing to the reconstruction of past ways of life. The threshing floor is an activity area that relates to subsistence practices in agricultural societies, yet identifying threshing floors in the archaeological record is difficult. We present a geoarchaeological study conducted at an Iron Age layered feature unearthed in 1998 at Tel Megiddo, Israel, in which we tested a previous assumption that it represents the remains of a threshing floor. Using micromorphology, mineralogy, elemental analysis, phytoliths, and dung spherulites, we show that the materials comprising the bulk of the layers in the Megiddo feature include large amounts of wood ash and the inorganic remains of livestock dung. Based on these results, coupled with ethnographic data on threshing floors and observations on the macroscopic traits of the feature under consideration, we conclude that the layered feature at Megiddo does not represent a threshing floor but a single-household trash heap. We suggest that the interpretation of similar features at other archaeological sites as threshing floors be reevaluated.     

Refining the definition of cultural levels at Karabi Tamchin: a quantitative approach to vertical intra-site spatial analysis

The visual identification of archaeological levels can be difficult when stratigraphy is complex. This study emphasizes the importance of three-dimensional intra-site spatial analysis as a means of testing the integrity of archaeological levels, including the identification of palimpsest deposits. A geographical information system (GIS) is applied to a three-dimensional spatial analysis of lithic and bone distributions from Karabi Tamchin, a Middle Palaeolithic site from the Crimea, Ukraine. K-means statistical clustering is combined with a series of data transformations to identify and interpret the vertical and horizontal spatial organization of the site. The results indicate that K-means cluster analysis, used in conjunction with GIS, provides an exceptional method of identifying discrete clusters of archaeological materials in three dimensions. Through an analysis of cluster contents within levels, it is possible to reconstruct and compare patterns of spatial organization at Karabi Tamchin, contributing to current debates regarding the cognitive complexity of Neanderthal populations.     

Investigating crop processing using phytolith analysis: the example of rice and millets

The application of crop processing models to macro-botanical assemblages has traditionally been used to interpret past husbandry practices and organisation of labour involved in crop-processing. Phytoliths offer an alternative method of analysis because they are durable in most environments, regardless of whether plant parts are charred, and the identification of plant types and plant parts allows them to be used in much the same way as macro-botanical remains. Indeed macro-remains and phytoliths are complementary datasets for examining the input of plant parts, such as crop-processing waste, into archaeological deposits. We outline crop-processing models in relation to macro-remains and then develop the framework for their application to archaeological phytolith assemblages. Rice and millet processing models are explored in relation to patterns expected in both macro-remains and phytoliths. The utility of these models is demonstrated with archaeological evidence from the site of Mahagara, an early farming site in North-Central India. The results indicate a way to employ phytoliths in archaeology which complements the fragmentary evidence available from plant macroremains.     

Late Holocene subsistence and social integration in Sierras of Córdoba (Argentina): the South-American ostrich eggshells evidence

Zooarchaeological research carried out on South-American ostrich eggshells from late pre-Hispanic site Arroyo Talainín 2 (ca. 1100–300 BP, Sierras of Córdoba, Argentina) is presented in this paper. The resource importance has been assessed focusing mainly on its economic and political dimensions for social-unit integration rather than its classical use as a seasonal indicator. Eggshells taxonomic identification was performed by quantifying shell-pore density, and determining two Rheidae species: greater rhea (Rhea americana) and lesser rhea (Rhea pennata). High frequencies of burned eggshell fragments indicate an unequivocal association between this resource and the human occupations recorded at this site. Regional-scale data suggests that egg consumption took place disassociated from the main-residential camps. These locations were rock-shelters occupied by small-dispersed household groups or large-group food processing and consumption sites such as Arroyo Talainín 2. Thus, a flexible approach for a food-consumption study is required to account for its spatial dimension. Only a regional-scale archaeological research will allow advances to be made in our understanding of the subsistence patterns and socio-political organization of late pre-Hispanic human societies.     

Activity-induced musculoskeletal stress markers (MSM) and subsistence strategy changes among ancient Hudson Bay Eskimos

Although archaeological evidence may express the results of several seasons of activity, the human skeleton, when correlated with archaeological and ethnographic data, provides information concerning daily activities performed throughout an individual's lifetime. Studies in occupational and sports medicine, along with electromyographic analysis of movement, have shown that different activities place different amounts of stress on human bone. In the present study, analysis of upper extremity musculoskeletal stress markers (MSM) has been used to clarify habitual activity patterns of two ancient Thule Eskimo groups from northwest Hudson Bay, Canada. Distinct pattern differences in muscle use occurred between Thule adult males and females and suggest possible gender-specific activity patterns that are not always discernible from the archaeological record alone. Temporal applications of the MSM data for Early and Late Period Thule support McCartney's theory of a substantial change in subsistence strategies through time, particularly among the adult males.     

Strontium isotope analysis of human tooth enamel from Barsinia: a late antiquity site in Northern Jordan

The archaeological site of Barsinia represents a model of a mixed subsistence strategy in the late antiquity of Jordan. Contrary to historians' belief that the late antiquity economy was stagnated, archaeological evidence at the site of Barsinia points to wealth accumulation as mirrored by the local wine industry and trade. As the economic growth may enhance population dynamics, the study tests the population mobility at the site using strontium isotope ratios from the human tooth enamel. The study comprised 12 right upper third molars and 12 rodent teeth samples. The results confirm that all of the sampled individuals were local to the area (raised in the area) and whose diets were probably obtained from spatially restricted localities in the region.     

Microscope observations and DNA analysis of wine residues from Roman amphorae found in Ukraine and from bottles of recent Tuscan wines

Morphological analysis by light and electron microscopy was conducted on wine residues from second century Roman amphorae found in Myrmekion (Ukraine). The results of the archaeological samples were compared with residues formed in bottles of wine from Tuscan vineyards, corked between 1969 and 1977 without filtration and enzyme or biochemical processing. Staining and histochemical observation of the archaeological and recent residues detected nucleic acids. Molecular analysis was also performed using nuclear microsatellite SSRs markers having high polymorphism to study genetic relationships. Genotype profiles of archaeological and recent residues were compared with contemporary cultivars in a data bank. Low homology of genotype profiles of all residues, and oral evidence, confirmed the presence of autochthonous varieties in recent wines and enabled indirect assessment of varieties detected in the archaeological material. The results confirmed that the archaeological material could be related to Sangiovese and indicated Roman wine trade as far afield as Ukraine, whereas the recent residues provided evidence of disappearing native Tuscany cultivars like Gorgottesco, Mammolo, Verdello, Rossone and Tenerone, used for table wines until the late seventies.     

The Ethnoarchaeology of Reptile Remains at a Lake Turkana Occupation Site, Kenya

The role of reptiles in hominid hunter–gatherer subsistence in Pleistocene Africa has been largely overlooked. This study examines the reptile component of a modern lake shore camp (site 20) assemblage of low archaeological visibility. Site 20, located on the eastern shore of Lake Turkana, has been observed from its creation to burial. The site is an ideal modern analogue for the interpretation of African prehistoric archaeological sites. Patterns of element loss, and patterns of bone modifications, namely burn, cut and slice marks, are examined. From this baseline data, three conclusions are drawn regarding the interpretability of reptile remains found at archaeological lakeside sites: (1) the MNI of crocodile remains at a site is likely to be similar to the original number of individuals which contributed to the deposited assemblage; (2) the MNI estimates of the turtle component will be much less than the original number of individuals in the deposited assemblage; and (3) patterns of bone modifications can be related to hominid food procurement and processing activities.     

Post-Roman crop production and processing: Archaeological evidence from Goldthorpe,South Yorkshire

The remains of a ditched field system dating from the late Iron Age to the early post-Roman period, and two associated corn drying ovens (dating to the 5th–6th centuries AD) were revealed during archaeological excavations at Goldthorpe, South Yorkshire. The site was excavated during 2012 and 2013, during which bulk environmental samples were taken in order to retrieve any surviving botanical remains from deposits associated with the corn drying ovens, and other features across the excavated area. Early post-Roman occupation is under-represented in the archaeological record, especially in northern England, as such human activity and subsistence during this period are currently not well understood. This paper combines evidence for the field system, the physical remains of the corn drying ovens and their associated botanical remains to further understand early post-Roman change and continuity in landscape use and crop production and processing practices.
