A red deer (Cervus elaphus L.) skeleton from seamer carrs, Cleveland, England: Provenance of the skeleton and palaeoecology of the site

A Red deer, Cervus elaphus L., skeleton from Seamer Carrs was excavated and the collagen fraction of one of the bones dated to 4330 ± 100 bp (Birm. 977). The bones were embedded in a limnic sediment that was dated to 7360 ± 120bp(Birm.882). This date was confirmed by the pollen assemblage, which indicated a Flandrian I/II chronozone age. The date of the Cervus bone is explained by its movement vertically downwards in the limnic sediment. Attention is drawn to the number of large mammalian skeletons that have been recovered from Seamer Carrs during drainage operations and subsequently, and to the mesolithic and neolithic artifacts recovered from the slopes around the Carrs.     

Thousand years of vegetation history revealed by pollen in a sandy soil,central Netherlands

Abstract

Within the scope of an interdisciplinary research project to determine the genesis and age of small clusters of oak trees, three soil sections in and three outside oak clusters in an ancient woodland/heath on the Veluwe, central Netherlands, were sampled for palynological analysis. The sections within the clusters show an undisturbed development from the Medieval period onwards, the sections outside the clusters are missing ca. 15 cm because of sod cutting associated with plaggen soil formation. The rate of downward movement of pollen was established, using known dates from the near surroundings.     

Environmental Change Since the Woodland Period in the Mid-Ohio Valley: Results from Patton Bog Sediment Core Palynological Analyses

Palynological analyses of sediment cores from Patton Bog in southeastern Ohio recorded environmental changes from ca. 1000 B.C. to the present, representing the first pollen core analyzed from this region. Pollen data show an increase in prairie species, implying periodic expansion of grassland environments during the Woodland period coeval with the initial collection and eventual domestication of Eastern Agricultural Complex seeds. It is suggested that these environmental changes influenced human decisions concerning plant domestication and diet in the mid-Ohio Valley.     

Chronology during the Bronze Age in the archaeological site Tell Qubr Abu al-‘Atiq, Syria

Archaeosediments are deposits with a direct or indirect anthropogenic component. They provide useful information about past human activities and interaction with the environment. When other materials, such as pottery, are present in archaeosediment layers, the combination of TL ages from pottery and OSL ages from sediments can provide complete data about the occupation and evolution of an archaeological setting. In Mesopotamia, tells are mounds formed by the debris of human occupation and the accumulation of muddy sediments mainly due to the decomposition of mud bricks in ancient towns. Many other materials such as pottery fragments, bones and charcoal can be found in the sediment layers. The combination of OSL, TL and radiocarbon ages can be very useful in the case of the Bronze Age Period in Syria, allowing the occupation sequence of such archaeological sites to be reconstructed. Tell Qubr Abu al-’Atiq, is located on the left bank of the Middle Euphrates River (Syria). The archaeological artefacts found in the sediment layers (pottery) collected during excavations in two areas of the site, indicated the occupation of the tell during the Early and Late Bronze Age by typological pottery classification. The radiocarbon ages of charcoal indicate that human occupation fits the archaeological hypothesis, providing an older and maximum occupation period between 2800 and 2300 BC and a younger period between 1400 and 900 BC. OSL dating of sediments shows ages younger than charcoal, while TL ages of pottery are generally older than sediment and charcoal ages. This can be explained as the different materials correspond to different events. The charcoal and pottery correspond to occupation periods, while sediments correspond to the further destruction of the site.     

UV-fluorescence microscopy and the coherence of pollen assemblages in environmental archaeology and Quaternary geology

UV-fluorescence microscopy provides a powerful tool for the assessment of the coherence of pollen and organic-walled microfossil assemblages in situations where recycling or the intrusion of younger pollen is suspected. It also provides sensitive information about the thermal maturity of pollen, important for assessing whether material has been heated. Examples are given from the Palaeolithic sites at Barnham, Suffolk, UK; Stanton Harcourt, Oxfordshire, UK; High Lodge, Suffolk, UK; Niah Cave, Sarawak, Malaysian Borneo; and Holocene sites at Wadi Dana, Jordan; Milldale and Creswell, Derbyshire, UK; and Dooncarton Mountain, County Mayo, Republic of Ireland.     

A palynological investigation of a second millennium BC bank-system in the black moss of Achnacree

Evidence of agricultural activity in Scotland during the Bronze Age is sparse. A bank system of that date, covered by a deep peat accumulation, in Argyllshire, Scotland has preserved a podzolic palaeosol. Palynological investigation of the palaeosol allows a consideration of potential prehistoric land use. The existence of a well developed iron pan in the palaeosol divides the soil pollen into two contrasting groups, suggesting two quite distinctive periods of land use. Also discussed are the problems which the processes of podzolization cause pollen analysts, the dating of buried soils and the possibility of periodicity in pollen movement through a soil.     

Changes in the Abundance and Diversity of Proteaceae in South‐western Australia: a Review of an Integrated Palaeoenvironmental Study

South‐western Australia is a globally significant hotspot of Proteaceae diversity. This review reports on changes in the abundance and diversity of Proteaceae in south‐western Australia. Using palynology, the data were obtained from three sediment sequences from the Eocene, Pliocene and Holocene, as well as a modern pollen rain study, in the context of a vegetation history framework. The total percentages of Proteaceae pollen in pollen counts indicate that the number of Proteaceae in the vegetation are highest at present, slightly lower, yet still high in the Eocene, reduced by the Pliocene and lowest in the Holocene. It was found that Proteaceous genera can contribute up to 50% of the total modern pollen rain. Sediment from Lake Lefroy showed Nothofagus‐dominated rainforest occurred in the Middle to Late Eocene. Proteaceae species were at least as diverse as today, contributing up to a maximum of 42% of the total pollen rain, and varying across small lateral distances. A laminated Pliocene age sequence from Yallalie confirmed other studies that south‐western Australia was covered by a rich vegetation mosaic consisting of heath and wet rainforest elements. Proteaceae species were a consistent component of the counts, although diversity and abundance (maximum 5%) were low. A Holocene record from Two Mile Lake, near the Stirling Range, recorded little environmental change. Proteaceae species were noted in low abundance, at a maximum of 3.5% of the total pollen count. It is likely that both changing pollination mechanisms and changes in associated vegetation are important in determining the dispersal of Proteaceous pollen.     

A bioarchaeological study of a Western Basin tradition cemetery on the Detroit River

Archaeological monitoring of construction in a Windsor city park on the Detroit River led to the discovery of an isolated cemetery containing the remains of eight individuals assigned to the Late Woodland Western Basin Tradition. At the request and consent of the contemporary First Nation community, tissue samples from five individuals were subjected to radiocarbon dating, mtDNA, and stable isotope analysis to confirm cultural affiliation and further understand the subsistence practices of these people. Radiocarbon dating placed the cemetery at the transition from the Younge phase (AD 900–1200) to the Springwells phase (AD 1200–1400). The stable carbon and nitrogen isotope results provide an unexpected but fuller understanding of Late Woodland Western Basin Tradition subsistence. All individuals were as enriched in carbon as those found on Iroquoian horticulturalist sites to the east, suggesting a very high reliance on maize. Nitrogen isotope values indicate that the protein component of the diet was comprised largely of high trophic level food sources, likely fish. An in situ osteological analysis identified a high number of carious lesions in the visible teeth, also suggesting a diet high in carbohydrates. The mtDNA findings support the antiquity of the Western Basin presence in Northeast North America through genetic links with the Hind Site, an Archaic site in southern Ontario. These results underscore the importance of such studies for providing novel insight into the archaeological histories and lifeways of this distinct Late Woodland tradition. This study also emphazises the need to work with descendant communities to provide them with information on the past that reflects their distinct heritage in the lower Great Lakes region.     

The goodness of fit and statistical significance of seriation solutions

This paper presents a method for determining the statistical significance and goodness of fit of seriation solutions based on correspondence analysis. The basic assumption is that seriation solutions corresponding to relative chronological sequences should have unimodal distributions of types across assemblages in a sequence. In order to evaluate significance of chronological signal in data, the observed number of modes of a seriation solution based on correspondence analysis is compared to a distribution of number of modes generated by randomization of the original data table. A quantitative measure of the goodness of fit is presented. The method is tested on two data sets: 1) archaeological data with a known chronological ordering 2) non-archaeological data without a chronological patterning. The method successfully detected a significant chronological signal in the former, and failed to detect it in the latter.     

Using multi-criteria cost surface analysis to explore past regional landscapes: a case study of ritual activity and social interaction in Michigan,AD 1200–1600

Major advances have occurred in the analytical use of GIS in archaeology, particularly in uses of this tool for furthering understandings of past social landscapes. A major focus of these efforts has been visibility studies and archaeologists have paid less attention to how GIS can facilitate the study of another important socio-spatial component, movement. This paper examines the GIS application of multi-criteria cost surface analysis as a robust technique for modeling past movement and applies this approach to the Late Prehistoric period (ca. AD 1200–1600) in Michigan as a case study. This analysis extends understandings of the role of localized connections and tribal territoriality with the spread of maize agriculture in this period and adds further support to the proposal that earthwork enclosures served as uniquely accessible ritual centers for social, economic and ideological interaction between separate tribal communities within the Late Prehistoric regional organization. By showing this technique can build on and validate models of past social developments, grant real insights into social connections and affiliations, and stimulate new directions for future research, this specific case illustrates the general heuristic value of multi-criteria cost surface analysis for exploring regional landscapes in archaeology.     

Persistence of the cultural landscape in Campania (Southern Italy) before the AD 472 Vesuvius eruption: archaeoenvironmental data

Cultural landscapes were prominent during the Early Roman period when agronomic knowledge allowed the spread of intensive land exploitation in most of the available land. The aim of this contribution is to explore whether for the Campania region (Southern Italy) archaeoenvironmental data would support continuity or change in the cultural landscape of Roman tradition in the 4th and 5th centuries. To do so, new data from two sites located on the northern slopes of the Vesuvius, both buried by the AD 472 eruption have been investigated. Charcoal analysis, ¹⁴C dating, and chemical analysis of organic residues were carried out in order to study the landscape and the food production at these sites. The results suggest the persistence of the Roman cultural landscape until the 4th and 5th centuries in this area. The landscape is in fact strongly marked both in agriculture and woodland exploitation and management, being characterized by managed chestnut forests as well as valuable cultivations of walnut, large vineyards, olive groves, and probably orchards and crops. The integrated approach with archaeobotanical and archaeometric analyses proves to be a powerful method for the study of the past landscapes, providing a good insight into the environment. Furthermore, this study provided the most ancient evidence of chestnut silviculture for wood.     

Laser ablation depth profiling of U-series and Sr isotopes in human fossils

We have explored laser depth profiling to obtain data sets for U-series as well as Sr analyses. Laser probing with an 81 μm spot size allows for the exploration of low uranium domains of up to 400 μm below the outer surface in tooth enamel. These low U domains will contain Sr isotope compositions of the individual, that are least affected by diagenetic Sr overprints. The small holes drilled for U surveying are not visible to the naked eye. Using larger spot sizes of around 233 μm, laser drilling can be used to obtain reliable U-series isotope data to a depth of approximately 1000 μm in enamel and around 1300 μm in bone. Furthermore, meaningful ⁸⁷Sr/⁸⁶Sr isotope data can also be obtained with this spot size. Using our sampling strategy, the overall damage to a human tooth is minute, as demonstrated on a Neanderthal tooth from Moula-Guercy. We expect that laser ablation depth profiling will become routine for gaining insights into the age of human fossils and the migrations of ancient humans.
