New perspectives on plant-use at neolithic Abu Hureyra, Syria: an integrated phytolith and spherulite study

Abstract Archaeobotanical remains contribute crucial evidence for shifts in human economy from foraging to farming, understanding early village life and the strategies employed by people in the past to cope with changing environmental conditions. However, differential preservation of plant proxies often leads to the over or under representation of some plant types. This research analyses phytoliths and faecal spherulites to provide new perspectives on human economy at the Neolithic site of Abu Hureyra, N. Syria (∼ 11100–6000 bc ) and plant taphonomy by comparing results with those from previous extensively analysed charred plant macro-fossils. This site is of especial importance as one of the earliest and largest pre-pottery Neolithic B farming settlements in the world, however, it was flooded following the construction of the Tabqa dam in the 1970s. This research therefore presents a case study for some of the methods that can be applied to archival material to continue research in areas of high archaeological significance that are no longer accessible. The presence of dung spherulites suggests a background faecal component in sediments throughout the lifespan of the site, and should therefore be considered as a depositional pathway for some of the charred plant macrofossils and phytoliths. Phytolith analyses show that a diverse range of vegetation types were exploited throughout the lifespan of Abu Hureyra, reflecting the site’s favourable position on the border of several ecotones, which likely contributed to its longevity over several millennia.
