The study presents archaeobotanical analyses of four Early Neolithic sites (Koprivets, Orlovets, Dzhulyunitsa, Samovodene) from Northeast Bulgaria. Those archaeobotanical data are linked to comprehensive series of 14C dates for the early Neolithic in northeastern Bulgaria allowing their attribution to high resolution radiocarbon chronology. In the considered sites the dominating cereal crop during the Early Neolithic is hulled barley (Hordeum vulgare var. vulgare), followed by einkorn (Triticum monococcum) and few emmer (Triticum dicoccum) what is a clear difference from the southern parts of Bulgaria where during the early Neolithic the dominating cereal crops are einkorn and emmer. Further principal crops, present from the earliest phases of the Neolithic in the region are lentil – Lens culinaris, pea – Pisum sativum, grass pea – Lathyrus sativus/cicera and flax – Linum usitatissimum. Wide spectrum of finds of gathered plants (at least 11 taxa) reflects the use of the natural vegetation resources. Useful for reconstructing the vegetation and land use in the Neolithic are also wood charcoal identifications, indicating apart of oak forests also presence of open vegetation, riparian forests and wetlands. The relatively open vegetation in the surrounding of the early Neolithic settlements could be one of the reasons why the corresponding locations were chosen by the Neolithic people to settle there. On the other hand this open vegetation could be caused by the Neolithic land use and animal husbandry, which have also led to certain reduction of the forests in the immediate surroundings of the settlements.

The present study aims to evaluate the effect of archaeological structures in the preservation and recovery of bird remains, in particular by considering the overall shape, open or enclosed, of the structure. Indeed, hollow structures, sometimes of an enclosed shape that may be constructed in masonry, are supposed to have a protective effect on the fragile bones of birds. This is evaluated by considering different variables, such as the ratio of bird remains compared to those of the main domestic mammals used as meat suppliers, the number of bird taxa, or the identification rates for different types of archaeological structures. In a second step, once the impact of the type of structure is evaluated, the same variables are examined according to the social status, to verify their relevance to document this aspect. It transpires that the bird to mammal remains ratio is strongly influenced by the type of structure, as it is higher in enclosed structures. However, some open structures also deliver high bird ratios, in particular at high status sites. In contrast, the bird identification rate is lower in enclosed structures, but this is probably related to the recovery method. Finally, the number of taxa seems more affected by the social status of the consumers responsible for the accumulation of an archaeological assemblage than by the kind of archaeological structure the faunal assemblage was discarded into. This has implications for sampling strategies since open structures, when sieved, sometimes yield high bird to mammal ratios as well as a high number of bird taxa. Therefore, more systematic sieving of large samples of sediment should be applied not only to enclosed structures but also to open contexts such as refuse layers or floors, especially in sites of (potentially) high social status.
