The second step is to analyse the archaeological assemblages in order to provide a list of taxa present in the natural environment of the site and/or exploited by the inhabitants. We use a low-power microscope to sort the light residues exported with the permission of the iraqi authorities. To identify the floral parts and the taxa we compare the archaeological specimens to atlasesĀ and the reference collection (herbarium) of the Institute of Archaeology of Oxford. We also use regional floras, mostly the Flora of Iraq and the Flora of Lowland Iraq. The main aim of the project is to determine the major crops exploited on the different settlements, according to their occupation period and geographical location.
