Some Critical and Methodological Aspects of Shoreline Determination: Examples from the Baltic Sea Region

Coastal shorelines worldwide are generally unstable and changing. The study of the precise relation between any archaeological site and the shoreline at the time when the site was used is therefore complicated, but still often not met with appropriate methodological approaches. In this article, we test models based on phosphate analysis and discuss how they can be used to detect ancient shorelines. We propose that a model of increased and oscillating phosphate values at the former water level is considered reliable and useful in areas with advancing shoreline.     

Paleodietary analysis of the sacrificial victims from the Feathered Serpent Pyramid,Teotihuacan

The consumption of different types and quantities of food frequently serves as a practice that expresses and reinforces social distinctions among individuals within complex societies. This study explores the dietary behavior of probable sacrificial victims interred within the offering complex underlying the Feathered Serpent Pyramid as a line of evidence concerning the identities and life experiences of individuals selected for inclusion within one of Teotihuacan’s public monuments. Stable carbon, nitrogen, and oxygen isotope values from rib samples of 12 individuals within the Feathered Serpent Pyramid complex were compared with those of 14 individuals interred in residential contexts within the city. Results provide new information concerning daily subsistence at Classic period Teotihuacan (ca. A.D. 200–600) and highlight the dietary distinctiveness of individuals interred within the Feathered Serpent Pyramid as compared to the general residential population of the site, particularly in terms of the carbon isotope composition of protein sources consumed by a number of the sacrificial victims. Oxygen isotope analysis suggests that most individuals from the Feathered Serpent Pyramid resided within the local Teotihuacan area during the years immediately prior to their deaths, indicating that the unique dietary pattern seen in stable carbon isotope values cannot be attributed to nonlocal residence prior to sacrifice. Rather, these dietary differences may suggest that the group of individuals selected for interment within the Feathered Serpent Pyramid offering complex maintained a distinctive social or economic identity as compared to the rest of the Teotihuacan population during their lives.     

The Kvarnbo Hall: Reconsidering the Importance of the Late Iron Age Åland Islands

This article accounts for and contextualizes a newly discovered monumental longhouse, a potential hall from the Late Iron Age, on the Åland Islands, Finland. The 45 m long building and its location are discussed in regional and historical context, in comparison to the full data set of coeval houses on Åland, and are argued to signal a social stratification, manifesting a higher level of achievement in this Late Iron Age society. This is further examined in the context of Iron Age settlement development. A rapid and large-scale colonization to Åland, evident in the middle of the first millennium AD, is for the first time explanatorily discussed, addressing the question of why this process occurred. Sudden population growth is linked in part to large-scale climatic disturbances, with fatal consequences in those areas of heavy agricultural dependency, forcing population movement to Åland driven by the presence of maritime resources, particularly seals, and available land.     

Provisioning Inka feasts at Tiwanaku, Bolivia: the geographic origins of camelids in the Pumapunku complex

While political integration can be achieved by many means, here we focus on the use of feasting and statecraft in the Inka Empire of the Andean Late Horizon (c. AD 1400-1532) in South America. In order to examine Inka political integration of the Lake Titicaca Basin of Bolivia, we examine paleomobility and paleodiet through radiogenic strontium and stable oxygen and carbon isotope data in archaeological camelid remains from the site of Tiwanaku. Mean radiogenic strontium isotope values from all archaeological camelid enamel and bone samples is ⁸⁷Sr/⁸⁶Sr = 0.70998 ± 0.00179 (1σ, n = 48), mean stable oxygen isotope values from a sub-set of archaeological camelid enamel and bone samples is δ¹⁸O_{carbonate (VPDB)} = −10.0‰ ± 2.6‰ (1σ, n = 18) and mean stable carbon isotope values from a sub-set of archaeological camelid enamel and bone samples is δ¹³C_{carbonate (VPDB)} = −9.0‰ ± 1.7‰ (1σ, n = 18). While many camelids consumed in these feasting events were likely local to the Lake Titicaca Basin, others came from a variety of different geologic zones, elucidating our understanding of Inka statecraft and the role of feasting in political integration in empires in the past.
