Micro-sampling of human bones for mobility studies: diagenetic impacts and potentials for elemental and isotopic research

The nature of long bone formation and the pathways of interaction between bone samples and the burial environment suggest that portions of the bones disconnected from the arterial system are resistant to diagenetic alteration. Preliminary work on femurs from Early Bronze Age hunter-gatherers in Cis-Baikal, Siberia shows that the nature and progression of chemical changes in the bone matrix due to microbial attack can be analyzed using laser ablation inductively coupled plasma mass spectrometry. Intra-osteon variability in elemental concentrations and strontium isotope ratios (⁸⁷Sr/⁸⁶Sr) indicate the presence of unaltered portions of bone within diagenetically modified bone and suggest that useful data remain accessible. These biogenic signals can potentially be useful for mobility research in broad terms and the smaller timescales within an individual's lifetime (months, years), accessible therein. Laser ablation micro-sampling of femur specimens showed that intra-osteon elemental composition of Ba, Re, and Cs varied within and was correlated between multiple osteons of a single bone. Portions of chemically unaffected bone were identified within, and effectively discriminated from diagenetically altered bone tissue. Areas showing visual alterations and erratic or uncorrelated Ca and Sr elemental results also had anomalous Sr isotope ratios, suggesting diagenetic alteration in those places. Compositional and isotopic analysis of intact portions of bone supports the hypothesis that hunter-gatherer groups in Cis-Baikal made numerous major movements during their lives. Microscopic analysis of long bones clarifies aspects of biodeterioration and correlations between trace elemental results and diagenetic alteration. Micro-sampling of intact portions of bone expands the scope of available materials for research on mobility and other aspects of human past behavior.     

The sponge genus Brachiaster (Pachastrellidae,Demospongiae) and its first known fossil representative,from the late Eocene of southwestern Australia

Pisera, A. & Bitner, M.A., December, 2007. The sponge genus Brachiaster (Pachastrellidae, Demospongiae) and its first known fossil representative, from the late Eocene of southwestern Australia. Alcheringa 31, 365‐373. ISSN 0311-5518.

The pachastrellid genus Brachiaster Wilson (Pachastrellidae, Demospongiae, Porifera) has had until now no known fossil representatives. Here we describe its first known fossil representative from the late Eocene of southwestern Western Australia, assigned to Brachiaster claudelevii sp. nov. Brachiaster claudelevii has well-developed axial canals in the mesotriders, which points to it being intermediate in character between the typical tetraxial desmas of lithistids, and tetraxial spicules of non-lithistid demosponges. This further supports the position of Brachiaster among the Pachastrellidae. The geographic and bathymetric distribution of the extant and newly described fossil representatives of Brachiaster indicates that the Eocene sponge described here is important in understanding the evolution of Indo-West Pacific sponges because it points to a long evolutionary history and complex biogeographic distribution of this lineage of pachastrellid sponges.

Social context of the unchambered megalithic long barrows in Middle Pomerania,Poland

This paper is an attempt at defining the social functions of the unchambered megalithic long barrows found in the ?upowa group of the Funnel Beaker Culture (TRB). The authors assume that their aim can be achieved by employing a cultural ecological approach, which leads to a determination of the following variables: exploitation efficiency of the local population, local territory, and size of that population. The values determined for these variables imply that only a small, limited number of the deceased members of the group were buried in the long barrows discussed. Thus, it is possible that burial functions were not the only and most important ones. The authors try to define the remaining functions of the long barrows.     

The building of the church of St Sophia in Kiev

The subject of this study is the much-debated question of when and under what circumstances the cathedral of St Sophia in Kiev was built. After an analysis of the primary sources and a critical review of the arguments in favour of a date of construction between 1017 and 1031, the author substantiates the view that the entire church, including towers and external ambulatories, was built and decorated between 1037 and 1046, and not, as some think, over a period of nearly a century.Because of the complexity of the sources, the construction of St Sophia is seen against the background of the cultural, political and ecclesiastical history of Kievan Rus' in the late tenth and eleventh centuries, including the building of the cathedrals of Cernigov and Novgorod, and the church of the Tithe and the katholikon of the Caves monastery in Kiev.The study sheds new light on the early history of Kievan stone architecture which, as some reasonably assert, was closely linked with the architectural school of Constantinople. The construction of the capella regia, known as the church of the Tithe in the 990s, by Greek masters, who followed the Porphyrogenite princess Anna to Kiev, was an isolated episode which was followed by a hiatus of forty years. The extensive building programme begun by Jaroslav the Wise after 1036, which continued after his death in 1054, was completed by Byzantine masters with local help, permitting the formation of native cadres of masons, artists and other specialists. It was the project of Faroslav which laid the groundwork for an indigenous stone architecture in Rus'.     

Joseph Retinger's conception of and contribution to the early process of European integration

The origins of the European Union are especially connected to its so-called founding fathers. One of them was Polish politician Joseph Retinger, who represented a functionalist point of view. This article aims to throw light on Retinger's contribution to uniting the Old Continent. The method applied in this article is a comparative analysis of Retinger's ideas with the early phases of integration. Many significant initiatives taken with a view to the future integration of Europe, such as the founding of the European League for Economic Co-operation (1946), the Congress of Europe held in The Hague (1948), the founding of the European Movement (1948), or the establishment of the Council of Europe (1949) to give just a few examples can all be associated with Retinger's activity. The author concludes that the importance of Retinger's European activities (concerning the early period after the Second World War) were so huge that he should be ranked among the pioneers of the modern European Union.     

Middle Holocene hunter-gatherers of Cis-Baikal, Siberia: An overview for the new century

The paper examines Middle Holocene hunter-gatherer adaptive strategies in the Baikal region of Siberia based on diverse data (radiocarbon, mortuary, geochemical, genetic, human osteological, and zooarchaeological) accumulated over the last 10–15 years. The new model emphasizes the cyclical nature of the long-term changes and recognizes similarities between the Early Neolithic and Late Neolithic–Early Bronze Age cultures. The overall impression seems to be that change in the region was rapid rather than gradual. A number of interesting correlations between various cultural and environmental variables have been identified. During the Early Neolithic and Late Neolithic–Bronze Age, the spatial distributions of mortuary sites, open landscape, and good fisheries are all correlated and both intervals are coeval with periods of environmental stability. For the Early Neolithic two additional sets of correlated variables have been identified: (1) the uneven distribution of fish resources, uneven distribution of the human population, and cultural heterogeneity; and (2) poorer overall community health, more extensive male travel and heavier workloads, and higher reliance on fishing. For the Late Neolithic–Early Bronze Age, the sets of correlated variables are somewhat different: (1) more even distribution of terrestrial game resources (herbivores), more even distribution of the human population, and cultural homogeneity; and (2) better overall community health, less travel and lighter workloads, more equitable distribution of labor between males and females, and higher reliance on game hunting. Viewed together, these patterns emphasize the much more dynamic pattern of hunter-gatherer cultural variability, temporally and spatially, compared to what was known before.     

Record of the meso- and neoholocene palaeoenvironmental changes in the Jesionowa landslide peat bog (Beskid Sądecki MTS. Polish Outer Carpathians)

The paper presents an analysis of depositional sequences of landslide peat bog situated in the depressions developed within the landslide landforms Jesionowa in the Beskid Sądecki Mts. (Outer Carpathians). The peat bog, with depositional sequence 2.80 m long, started to form at the beginning of the Atlantic Phase ca. 6390–5910 cal BC. Palynological and lithological analyses as well as several (14) radiocarbon age determinations of different horizons in the sediments enabled the reconstruction of palaeoenvironmental changes during the Meso-and Neoholocene. The increase in climate humidity at the beginning of the Subboreal and Subatlantic Phases was observed as delivery of minerogenic material to the peat bog basin and formation of a mineral horizon and an illuvial level within the peat. The particularly intensive delivery of allochthonous material to the peat bog took place at the beginning of the Subboreal Phase and was the result of both significant humid climate and increased human impact (colonization of the Funnel Beaker Culture) in the landslide area. Similar influence of younger colonisations of landslide area (Przeworsk Culture and, later, Valachian colonisation) was also recorded within the deposits of peat bog (illuvial and mineral horizons) in the early Subatlantic Phase. Rejuvenation of the landslide zone and formation of the younger landslide were connected with the increase in climate humidity at the beginning of the Subboreal Phase. The peat bog deposits situated within this younger landslide, which are ca. 1.8 m thick, are significantly contaminated with mineral material.     

Human taphonomy at Khuzhir-Nuge XIV,Siberia: a new method for documenting skeletal condition

This paper employs a new three-part method for documenting skeletal condition in order to examine human taphonomy at the Glaskovo (5000–3700 BP, calibrated) cemetery of Khuzhir-Nuge XIV, located in the Lake Baikal region of Siberia (Russia). Relationships among three distinct aspects of condition – completeness, fragmentation, and articulation – and 15 identified taphonomic factors are investigated in order to explain the high variability observed at the site. Intrinsic skeletal characteristics such as element type and age at death were found to be responsible for some of the variable condition, but cultural activities, particularly mortuary practices, appear to have played even greater roles – both direct and indirect. Articulation, in particular, appears to have been an aspect of skeletal condition which was directly affected by a number of cultural practices. In addition to applying a new method of documenting skeletal condition to human taphonomic analyses, this research explains much of the variable condition observed at Khuzhir-Nuge XIV and emphasizes the significance of cultural practices as taphonomic agents affecting human remains.     

Avian Remains from Late Pre-colonial Amerindian sites on Islands of the Venezuelan Caribbean

ABSTRACT

This paper presents the results of the analyses of 3793 bird remains archaeologically recovered from seven late pre-Hispanic sites (～AD 1000–1500) on islands of the Venezuelan Caribbean. In order to address subsistence and manufacturing uses of bird bones, we first discuss the recovery process of this unique sample. We proceed to investigate the bones' archaeological contexts as well as the taphonomy in play and analyze diverse bone categories. We found that indigenous peoples consistently targeted several families of birds for food or feathers or both, and that avian bones were used for fashioning tools and adornments. We also discuss possible signatures of island campsite seasonal occupancy as inferred from the bio-ecology of the identified bird taxa. The data suggest that the differentiation of nesting grounds between the Red-footed and Brown Booby in the Southeastern Caribbean may be a result of anthropogenically-induced adaptation. The findings discussed in this paper open challenging avenues for assessing long-term changes in bird communities including the dynamics of resident and wintering bird populations.
