First Contributions of Charcoal Analysis to the Study of the Specialised Fishing Site of Bayovar-01 (5th–8th Centuries AD), Extreme Northern Coast of Peru
Résumé
Recent archaeological excavations carried out at the site of Bayovar-01 (occupied from the 5th to 8th centuries AD) in the Sechura Desert provide new data on the activities and adaptations of the desert’s ancient inhabitants. The presence of two small structures, a large activity area containing a significant amount of fish remains and traces of large hearths, indicate that Bayovar-01 was an opportunistic settlement, benefitting from favourable environmental conditions and serving as a specialised site for fishing and the preparation of fish. The analysis of charcoal remains from features corresponding to large hearth remains sheds light on practices of firewood gathering and usage. Taxonomic and morphological analyses reveal strong preferences for certain taxa, possible gathering strategies combining dead wood collection and tree felling, the usage of several different tree parts, and consistent combustion conditions across the processing features. Despite selection biases, taxa composition suggests the existence of different environmental conditions in the desert in the past, related to the presence of a palaeo-lagoon. Anthracological analysis thus has a potential that exceeds mere taxonomic identification of firewood, revealing gathering and usage practices, as well as insights into taxa availability that have implications for ecological and environmental variations.
