The recovery and interpretation of microvertebrate bone assemblages from archaeological contexts

The analysis of microvertebrate remains recovered from buried contexts is frequently problematic for archaeologists. Diminutive size is a major obstacle to recovering, identifying, and interpreting microfaunal bone materials successfully. Their taphonomic history is often obscure, thus the significance of microvertebrate accumulations for settlement, subsistence, and ecological interpretation is difficult to evaluate. Recognizable and reliable archaeological signatures are sought for assessing the effect of taphonomic history on microvertebrate assemblages. Relevant signatures of bone damage, skeletal survivorship, taxonomic composition, and context are examined in assemblages produced and modified through accidental non-predator-related death, predator accumulation, and postmortem alteration.     

Pitfalls in the environmental interpretation of insect death assemblages

Attention is drawn to the absence of an established basis for the reconstruction of past environments from insect death assemblages. A naïve reconstruction based on a modern death assemblage from a drain in the City of York is tested and shown to be inadequate in a number of respects. Certain of the habitats indicated by the fauna are absent from the surroundings, while the importance of some others is exaggerated. It is concluded that these errors were brought about by the active or passive long distance transport of insects.     

FOCUS: on the use of the petrous bone for estimating cranial abundance in fossil assemblages

Low representation of braincase bones in zooarchaeological assemblages suggests that skulls have been intensively processed by Levantine Epipalaeolithic foragers; most cranial elements are often unidentifiable and are considered poor candidates for quantifying crania. In contrast, the petrous bone is usually found complete, and was found to be easily identifiable to body size category. Use of the petrous bone in fossil assemblages analyses leads to better estimation of the occurrence of cranial elements, and thus of skeletal part representation. We therefore suggest use of the petrous bone for detecting bone destruction and selective transport in faunal assemblages.     

A new experimental study on percussion marks and notches and their bearing on the interpretation of hammerstone-broken faunal assemblages

Preliminary experiments on bone breakage have shown the potential utility of quantifying some of its diagnostic features (percussion marks, percussion notches) for taphonomic inferences about human and carnivore involvement in bone breakage in faunal assemblages. The present study increases the range of experiments undertaken to understand the identification of hammerstone percussion (dynamic loading) and its differences from carnivore bone breakage through tooth pressure (static loading). This study contributes to a better understanding of frequencies of percussion marks, uncovers and quantifies those percussion marks that lack key diagnostic features to be identifiable and that could be mistaken with carnivore tooth marks, quantifies notch types, shows different size ranges for notches on bones from small and large fauna than previously reported, quantifies the proportion of notches bearing percussion marks, and introduces new size data for percussion (impact) flakes and percussion marks. Furthermore, all these variables have been applied to a dual experimental set: one experiment using non-modified hammerstones and another based on the use of modified hammerstones. Results vary considerably according to hammerstone type. Some of these taphonomic variables increase the range of equifinality when identifying marks and notches created by different human and non-human agents. This calls for further caution when using isolated variables and features rather than a holistic approach to make taphonomic inferences.     

The use of multiple discriminant analysis in classifying prehistoric phytolith assemblages recovered from cooking residues

In the investigation of the dispersal of maize (Zea mays ssp. mays) from south-central Mexico to the northern and southern limits of agriculture in the Western Hemisphere archaeologists and paleoethnobotanists are increasingly turning to the microbotanical record. Recent analysis of phytolith assemblages from charred cooking residues on pottery sherds in central New York recovered using 209 rondel phytolith variables has identified maize as early as 2270 ± 35 B.P. In this article we use discriminant analysis to re-classify these rondel phytolith assemblages resulting in only seven variables. The results are consistent with those achieved earlier using many more variables and a less formal statistical approach in terms of classification and in similarity of the original and reduced data matrix as seen by the Mantel test and cluster analyses.     

What goes in does not always come out: The impact of the ruminant digestive system of sheep on plant material,and its importance for the interpretation of dung-derived archaeobotanical assemblages

Abstract

On archaeological sites where livestock dung was a major fuel source, plant material that survives digestion intact may well be preserved in the remnants of dung-fuelled fires. Preserved plant remains which were derived from dung relate to the diet of animals, and thus provide a way of investigating the agro-pastoral economies of the past. In order to improve our understanding of the taphonomic processes to which plant material is exposed to during digestion, we applied archaeobotanical methods to the analysis of dung from sheep fed a known diet of cereal and wild plant material. Two clear patterns emerge from these investigations. First, cereal material (grain or chaff) survives digestion poorly and was rarely found in the dung analysed. Second, large proportions of seeds of various wild species survive digestion in an identifiable form, probably due to their small size and/or protective coating. These findings are crucial for reliable interpretation of dung-derived plant material in archaeological settings.     

A side-scan sonar and high-resolution Chirp sub-bottom profile study of the natural and anthropogenic sedimentary record of Lower Lough Erne,northwestern Ireland

A geophysical survey (side-scan sonar and high-resolution sub-bottom profiling) combined with established chrono- and bio-stratigraphic markers are used to reconstruct the evolutionary history of Lower Lough Erne, northwestern Ireland since the end of the last glacial. Discrete acoustic units define four prominent sedimentation cycles, one Late-glacial and three Holocene, within the seismic stratigraphy. Basin development is predominantly controlled by climate until the Mid Holocene when the effects of cultural activity are related to pronounced signatures in the seismic record. An enhanced reflector marking the termination of the Early Holocene sedimentation cycle is associated with the elm decline and forest clearance during the Neolithic (between approximately 5800 cal. BP and 5300 cal. BP). The associated increase in sediment input, by infilling minor topographic lows and basins, has a smoothing effect on the morphologic expression of the original basin. Onlapping and truncated reflectors in the penultimate acoustic unit define further modification of lake bed relief by removal of sediment from the system during engineered lowering of the lake levels that began in the 1880s. Acoustic anomalies identified on the side-scan sonar data are linked with cultural activity and are identified as having the potential to facilitate the recent establishment and migration of invasive zebra mussels through the Erne system.     

Differentiating between anthropogenic calcite in plaster,ash and natural calcite using infrared spectroscopy: implications in archaeology

Infrared spectroscopy provides information not only on the type of calcium carbonate polymorph, but also on the extent of atomic order. In calcite, three major infrared absorption peaks are identified: ν₃, ν₂, and ν₄. It was shown that the ratio between ν₂ and ν₄ bands reflects the order of the calcite crystal structure. In this paper we analyse this ratio in geologically formed calcites, archaeological plasters, modern plasters and experimentally prepared plasters. For the geological calcite, the values of the ν₂/ν₄ ratio are around 3, whereas for the experimentally prepared plasters, the values are around 6.5. The ν₂/ν₄ ratio for archaeological plasters varies from 3 to 6. This shows that a high ratio is indicative of disorder in the crystal, and implies that the calcite was formed from calcium oxide at high temperatures. It also implies that this disorder can be preserved for at least 14,000 years. The ν₂/ν₄ ratio of calcite from archaeological sites can thus be used to differentiate between anthropogenic calcite, such as in plaster, mortar and wood ash, from geogenic calcite, such as in limestone. The ratio may also be used to identify plaster or ash that still retains its original crystals and therefore carbon-14 content.     

The chronology of the Valley Enclosures: implications for the interpretation of Great Zimbabwe

The recent structuralist model of the social organization of space at Great Zimbabwe, proposed by Huffman, is critically examined in the light of new chronological data. Architectural histories of the Western and Central Valley Enclosures (Posselt and Phillips Ruins respectively) are used to show the complex changes that occur through time in the social meaning of spatial organization. It is argued that these changes are not adequately accounted for in Huffman's model. The Western Valley Enclosure, dated on the basis of a large piece of blue-on-white Chinese porcelain of the Honghzi period (Ming Dynasty, AD 1488–1505) recovered from a sealed context, was still occupied when most other areas of Great Zimbabwe were abandoned. Huffman's incorporation of these enclosures into a synchronic structuralist interpretation of the site is therefore probably invalid. These new data highlight the importance of chronological control in the development of structural and symbolic interpretations of Great Zimbabwe.

Résumé Le modèle structuraliste de l'organisation sociale de l'espace à la Grande Zimbabwe proposé récemment par Huffman est examiné de façon critique, en fonction de données chronologiques récentes. Les histories architecturales des enclos des vallées Ouest et du Centre (Posselt et Phillips Ruins) sont utilisées afin de démontrer les changements complexes subit au cours du temps par la dimension sociale de l'organisation de l'espace. Les auteurs proposent que ces changements ne sont pas reflétés de manière convaincante par le modèle de Huffman. L'enclos de la vallée de l'Ouest est daté par la présence d'un fragment de porcelaine chinoise large, bleu sur blanc, appartenant à la période Houghzi (Dinastie de Ming 1488–1505 AD), trouvé dans un contexte scéllé; ceci prouve que le site était encore occupé alors que la plupart des autres quartiers de la Grande Zimbabwe étaient déjá abandonnés. L'incorporation par Huffman de ces enclos dans l'interprétation synchronique structuraliste du site n'est donc probablement pas correcte. Ces données nouvelles mettent en lumière l'importance du control chronologique pour le développement d'interpretations symboliques et structuralistes de la Grande Zimbabwe.

     

The use of forest resources in central Iberia during the Late Iron Age. Insights from the wood charcoal analysis of Pintia,a Vaccaean oppidum

Charred woods may be used to effectively reconstruct past wood acquisition strategies. We used anthracological data from the pre-Roman settlement of Pintia (Padilla de Duero, Valladolid) to examine the use of forest resources at the local scale. Palaeoecological data revealed heterogeneous landscapes in the inland northern meseta with environments that offered diverse sources of wood for the inhabitants of Pintia, one of the first cities of inland Iberia. Pines (Pinus pinea/pinaster and Pinus sylvestris/nigra) and both evergreen and deciduous Quercus L. and Juniperus L. were the main taxa identified as both fuelwood and construction elements, but the assemblages and frequencies of these taxa differed depending on their use. We also examined the potential of models from human ecology by considering the frequency, handling time and the relative technological value of each taxon to model how people gathered wood resources. The results suggest that although local availability affected the forest resources that were used by the Vaccaei people, specific taxa were positively selected for specific uses.     

A method for chronological apportioning of ceramic assemblages

Artifact assemblages from long-inhabited sites may include ceramic types and wares from multiple time periods, making temporal comparisons between sites difficult. This is especially problematic in macro-regional data sets compiled from multiple sources with varying degrees of chronological control. We present a method for chronological apportioning of ceramic assemblages that considers site occupation dates, ceramic production dates, and popularity distribution curves. The chronological apportioning can also be adjusted to take into account different population sizes during the site occupation span. Our method is illustrated with ceramic data from late prehispanic sites in the San Pedro Valley and Tonto Basin, Arizona, U.S.A., compiled as part of the Southwest Social Networks Project. The accuracy of the apportioning method is evaluated by comparing apportioned assemblages with those from nearby contemporaneous single component sites.     

The impact of mining activities on the environment reflected by pollen,charcoal and geochemical analyses

This article presents results of a multi-proxy study of a fen deposit in the former mining district of Falkenstein near Schwaz in the Tyrol, Austria. The aim of the study in the framework of the special research program HiMAT (The History of Mining Activities in the Tyrol and Adjacent Areas – Impact on Environment & Human Societies) was to disclose the ecological impact of mining in pollen and heavy metal diagrams and to create a model combining the changes in palaeoecological proxies with historical evidences for mining. The application of this palaeoecological–historical model to prehistoric times allowed us to reconstruct the impact of mining and metallurgic activities in the surroundings of the fen during the last millennia. The results of stratigraphy, radiocarbon dating, LOI, pollen and micro-charcoal analyses as well as geochemical analyses of scandium, lead and lead isotopes validated by historical and archaeological data are hereby presented.     

The farmer interpretation of Danish history

This paper is an overview of the Anglo‐Icelandic fishery disputes from 1952–1976. Its main emphasis is on the negotiations between the British and the Icelandic governments but it also addresses other aspects of the disputes, such as the effects they had on Iceland's relations with NATO and the United States and the effect on the balance of power between the Eastern and Western bloc in the North‐Atlantic.

The role of the museum in interpretation: The problem of context

The key questions in interpreting objects in museums are: What are they doing there? and Where did they come from? National and local importance are not mutually exclusive: the critical difference is between intrinsic value, and value through context or association. Context is an integral part of interpretation. Experts can visualise an original location or environment; ordinary museum visitors need the context of people, or place, or familiar activities, to be able to relate to unfamiliar objects. Is seeing a good replica as good as seeing the original?     

Ashes to ashes, charcoal to dust: micromorphological evidence for ash-induced disintegration of charcoal in Early Neolithic (LBK) soil features in Elsloo (The Netherlands)

Charcoal and other forms of charred organic material - an important part of the archaeological record - consist of benzenoids. Such components are unstable in basic or alkaline conditions. Since ashes are alkaline, this means that archaeological charcoal may have been disintegrated and lost if they were buried together with ashes, e.g. as in fireplaces. Ash may also cause clay translocation in decalcified loess because of the disaggregating effect of K⁺ ions in the soil solutions. We investigated the interplay of these two processes, using micromorphological samples from the Early Neolithic site at the Joannes Riviusstraat in Elsloo. Evidence for charcoal disintegration was found in the form of cavities in charcoal fragments, most commonly filled in with thick reddish limpid clay coatings. The combination of cavities and clay coatings are evidence for the disintegration of charcoal under the influence of ash. Ash may also have been instrumental in preserving small bone fragments in these decalcified well-drained loess soils. The evidence of ash-induced charcoal disintegration implies that charcoal preservation in the archaeological record is dependent on (1) whether or not is was buried alongside with ashes, and (2) on various soil characteristics that determine that determine how quickly the ash-derived alkalinity and potassium ions are leached.
