Abstract

Highlights: Microscopic fibres and hairs can be detected from archaeological soil samples. Animal hairs and feathers complement osteological data. Modern textile fibres have been accumulated in soils from various sources. The dating of minuscule fibres is challenging. Contamination needs to be controlled at every stage of the research. Abstract: Microscopic animal and plant fibres detected in archaeological contexts are a valuable source of information regarding textile production, use-histories of artefacts and in studying mortuary practices. At the same time, recent research on microplastic pollution has revealed the ability of fibres to move even long distances and accumulate in various terrestrial and aquatic contexts. In this paper we discuss the accumulation of 100–1000-µm-long animal hairs, bird feather barbules and textile fibres at Kvarnbo Hall, a Nordic Late Iron Age high-status settlement site in the Åland Archipelago, Finland. The hairs and barbules detected in soil samples reveal important information on the use of furs and downy feathers at the site. However, our study reveals that the microparticles sampled in the 6th–11th-century contexts represent not only the prehistoric phase of the site but can also be ascribed to the later land-use history of the area. We also speculate that long-distance air-borne particles might be one possible contamination source of fibres.
