Seasonality of birth and diet of pigs from stable isotope analyses of tooth enamel (δO, δC): a modern reference data set from Corsica,France

Since domestication during the mid 11th millennium BP in the Near East and the 8th millennium BP in China, the pig has played an important role in human diet and economy. The objective of this study is to evaluate the potential of stable oxygen and carbon isotopes sequential analyses of pig tooth enamel to investigate pig seasonality of birth and diet, as these are important parameters for the reconstruction of pig herding strategies in ancient societies.     

Ritual practices and collective consumption of animal products at the Iron Age rural settlement of Mas Castellar de Pontós (Girona,Spain) (5th–4th centuries BC)

Abstract

Animals have played an important role in certain ceremonies or rites in the past. During such activities, animals may have been alive, dead or been used as raw material. The disposal of detritus from these practices can lead to the formation of faunal assemblages with a particular taxonomic and anatomic composition. At the Iron Age ‘Mas Castellar de Pontós’ site (Girona, Spain), associations of archaeological materials excavated from Pit feature FS362 were suggestive of deposits arising from collective ceremonial consumption. Analysis of the 1309 mammal remains recovered from this feature is used to determine the nature and dynamics of the ceremony. At the same time, the relationship of these faunal remains with the other archaeological materials recovered in the pit will allow light to be shed on the significance and importance of these ceremonies in the framework of the social and political relations that governed the life of the inhabitants of this settlement.     

Harvesting molluscs in the Eneolithic: a study of freshwater bivalve accumulations from the tell settlements of Borduşani-Popină and Hârşova (Romania, 5th millennium BC)

Freshwater bivalve shells are frequently identified in faunal assemblages from Neo-Eneolithic tell settlements along the Danube River valley in South-East Romania (5th millennium BC). Up until now, significant accumulations of freshwater bivalve shells have been identified only in household refuse areas of the settlements, where they form consistent shell layers. The origin and formation of such shell accumulations and, more generally, the role of bivalves in the animal economy of the prehistoric populations that inhabited the settlements, are poorly understood. Two freshwater bivalve shell accumulations were studied in household refuse areas of Eneolithic tell settlements, one at Bordu?ani-Popin? and the other at Hâr?ova tell. The occurrence of similar accumulations in the two settlements indicates generalized practices between the two communities. This first study of such accumulations addresses the relationship between bivalves and other animal species used in alimentation by the two Eneolithic communities, as well as the relationships between these communities, their environment, and the evolution of the settlements. Bivalves were harvested in the close vicinity of the settlements and large quantities were obtained only towards the end of the summer season. During this season there is an inverse relationship between high water levels in the river and the availability of bivalves for harvesting. Bivalves played an important role in the alimentation of the prehistoric populations – at Hâr?ova tell their contribution to alimentation in terms of energetic yield surpasses that of fish, at least for the short period of time represented by the stratigraphic sequence analysed. Bivalve shells were used, along with other types of household refuse, in construction techniques aimed at limiting soil humidity in the settlements and inside the dwellings.     

A bioarchaeological approach to the Iron Age in Switzerland: stable isotope analyses (δ<Superscript>13</Superscript>C, δ<Superscript>15</Superscript>N, δ<Superscript>34</Superscript>S) of human remains

In Switzerland, a large number of Iron Age burial sites were found in the last century. Changes in living conditions and socio-cultural behavior may have occurred over time and space and could be reflected in the dietary habits, social stratigraphy within populations and migration patterns. This study attempts to shed light on these aspects with the application of stable isotope analyses. Human remains from 11 different burial sites (n?=?164) in the area of today’s Swiss Plateau and Swiss Alpine regions were investigated. Temporal and geographical variations as well as sex and age-related dietary differences were analyzed through isotopic studies (δ¹³C, δ¹⁵N, and δ³⁴S). In total, the data of 129 individuals could be evaluated. Highly significant differences between the burial sites were found, with higher δ¹³C and δ¹⁵N values in the Alpine regions. Cultural and/or climatic changes as well as the different geological conditions might have led to distinct patterns of crop cultivation and animal husbandry and consequently to significantly different dietary habits in the Plateau and the Alpine regions. The data indicate a higher intake of millet and animal protein including early dairy production in the southern regions, probably influenced by the Mediterranean world. Cultural exchange between geographical regions might have been facilitated by migration during the Iron Age as suggested by the δ³⁴S.
