Archaeological excavations of the Early Iron Age site of Kalakača in northern Serbia revealed the presence of numerous pit-features and traces of several possible above-ground structures. A number of pits were interpreted as storage features. Moreover, the charred plant remains in some of them were taken as an evidence of the function of the pits as crop stores/granaries. Archaeobotanical analysis confirmed the presence of a range of crops in the pits; however, the circumstances in which the charred crop remains were found strongly suggest that there is no direct connection between the plant material and the pit-features. No traces of in situ burning were detected in the excavated pits, demonstrating that the charring of plants happened outside. The use of charred plant remains as evidence for the storage of crops in the Kalakača pits can thus be dismissed. The plant material was perhaps charred within the surface structures. The analysis of the type of plant parts re-deposited in the pits reveals the presence of crop products – chiefly millet grain (most likely semi-cleaned) and some barley grain; and crop processing by-products – wheat and barley chaff. Millet grain may have originated from millet stores; cereal chaff may have arrived in the pits as daub temper or as crop processing residue discarded in fire.
The lower part of a sediment core taken from the Ezero lake, next to Tell Ezero, in the Thracian Plain, Bulgaria, covers the period 15500–13500 calBP (Greenland Ice Core Stages G1-1c–1e). The recovery of plant macrofossils as well as pollen grains indicated that, far from a largely treeless grassy steppe vegetation, there were stands of trees and bushes as well as a rich wetland flora. Archaeological, ethnographic and ethnohistoric investigations of over 70 plant taxa showed that 20 taxa had documented use exclusively for food, 14 for exclusively medicinal use and 14 for both uses; moreover, several taxa were utilised or present in coeval sites such as the Franchthi Cave and in southwest Germany. The presumption is that Final Palaeolithic communities in the Thracian Plain would have made good use of such a rich supply of food and medicinal plants. However, there is a variety of reasons – whether taphonomic, research led or pedagogical – for the current absence of any Final Palaeolithic sites in the Thracian Plain. A hypothetical mating network centred on Ezero puts this problem in spatial context.
