Multi-method Analysis of Avian Eggs as Grave Goods: Revealing Symbolism in Conversion Period Burials at Kukruse,NE Estonia

Eggshells are unusual finds in the Iron Age of eastern Europe (500 BC–1200 AD) deserving extra attention in terms of analysis as well as interpretation. This paper discusses two rare eggshell finds, discovered in female burials at the conversion period (12th–13th century AD) cemetery at Kukruse, NE Estonia. Our multianalytical study combining FT-IR, SEM(-EDS), microscopy and ZooMS provides an overview of methods applicable for identifying egg species, their predepositional history and curation. Based on the analytical results and the comparative analysis of the content and context of these two burials, we argue that different aims and connotations lay behind depositing eggs as burial goods, allowing well-supported interpretations of both pagan and Christian religious worldviews simultaneously.     

Late Holocene subsistence and social integration in Sierras of Córdoba (Argentina): the South-American ostrich eggshells evidence

Zooarchaeological research carried out on South-American ostrich eggshells from late pre-Hispanic site Arroyo Talainín 2 (ca. 1100–300 BP, Sierras of Córdoba, Argentina) is presented in this paper. The resource importance has been assessed focusing mainly on its economic and political dimensions for social-unit integration rather than its classical use as a seasonal indicator. Eggshells taxonomic identification was performed by quantifying shell-pore density, and determining two Rheidae species: greater rhea (Rhea americana) and lesser rhea (Rhea pennata). High frequencies of burned eggshell fragments indicate an unequivocal association between this resource and the human occupations recorded at this site. Regional-scale data suggests that egg consumption took place disassociated from the main-residential camps. These locations were rock-shelters occupied by small-dispersed household groups or large-group food processing and consumption sites such as Arroyo Talainín 2. Thus, a flexible approach for a food-consumption study is required to account for its spatial dimension. Only a regional-scale archaeological research will allow advances to be made in our understanding of the subsistence patterns and socio-political organization of late pre-Hispanic human societies.
