a 2000 micron mesh to catch the heavy fraction, with the overflow
feeding into a 500 micron mesh to catch the light fraction. In this
manner, sediment from 43 separate features was floated, often
subdivided into several contexts (50 in total). In total 2006 litres of
sediments were floated from the Botai site.
Sorting and identification of archaeobotanical material took place
at the University of Cambridge in the George Pitt-Rivers Laboratory
for Bioarchaeology. Each flotation sample was sorted individually by
selecting and counting all charred seeds within the sample. All of the
retrieved flotation samples from the sites was sorted and analysed.
The archaeobotanical samples were identified using a low-power
stereomicroscope (x6-x40, the reference collections available at the
George Pitt-Rivers Laboratory for Bioarchaeology and the Digital
Seed Atlas of the Netherland, the Atlas of Seed.
The extensive archaeobotanical investigation conducted at the
Botai resulted in no evidence of domesticated plant remains. The
recovered plants consisted mainly of wood charcoal, and charred
seed of
Chenopodium sp. (goosefoots),
Rumex sp. (docks),
Carex sp.
(sedge),
Polygonum sp. (knotweed),
Stipa sp./
Bromus sp.,) species
that were identified inside living house and could have possibly been
used for food.
Achillea sp. (yarrow),
Artemisia sp. species have both
aromatic and disinfectant properties. Archaeobotanical data are not
suggestive of a quotidian use of food plants by the Botai inhabitants.
The findings are consistent with a heavy dependence upon animal
products in their diet with a very minor contribution of wild plant
foods.
