Palaeoethnobotanical studies of the Neolithic settlement in Hidden Valley, Farafra Oasis, Egypt

The Neolithic site at Hidden Valley, Farafra Oasis, Egypt (6028±150 – 5163±374 cal B. C.) on the shores of a playa (dry lake basin in the desert), yielded a large quantity of carbonized plant remains from post-holes, hearths, querns and a corridor. The plant remains could have become carbonised during food preparation, or when fuel included seeds. Rich and diverse floras were retrieved from 40 soil samples, in all 534 seeds, grains, spikelets, culm fragments and leaflet fragments which were attributed to 30 taxa in the flora of Egypt. Wild grasses from almost all samples represent 83% of the plant remains. Quantitative correlation between plants remains and archaeological contexts is discussed. The highest density of plant remains was recorded from pot-holes (in which pots were stood), while sediments recovered near querns show the lowest. The economy of the site was apparently based mainly on herding associated with the gathering of grasses which suggests that the climate at Farafra during the middle Holocene (6077–4511 cal B. C.) was wetter than today's, with winter and summer rainfall. A reconstruction of the vegetation around the site comprises reed plant cover, aquatic and wetland plants and desert savanna.
