<p>Skateholm I and II cemeteries form the core of a notable Late Mesolithic activity area located in southern Sweden on the coast of the Baltic Sea. The burial sites date back to approximately 5,200–4,800 BCE, representing the final stage of the hunter-fisher-gatherer way of life. The cemeteries have been instrumental in advancing our understanding of Late Mesolithic societies in Northern Europe by shedding light on aspects such as material culture, ritual practices, and social organization. For the first time, evidence of perishable soft organic materials such as fur, feathers and plant fibres were investigated in 35 burials in Skateholm I and II. The research was based on the identification of microscopic fibre remains in soil samples that were collected during the excavations in the 1980s. The research provided indications of clothes, headgear, and footwear as well as the use of soft organic materials for grave furnishing and possible wrapping. Microscopic fibres were recovered even in burials that lack other grave goods. Moreover, the species composition was consistent with the reconstruction of human-animal relations based on osteological studies. Our research underlines the importance of microarchaeological analysis of graves in search of highly decomposed organic materials which may facilitate the full recognition of feathers, furs and fibres in archaeological mortuary research. In future, microarchaeological identification of highly perishable organic materials can provide hitherto invisible zooarchaeological find material to widen our understanding of past material culture.</p>
