The complex processes of cultural and historical development that took place at the end of the Mesolithic and the beginning of the Neolithic to the east of the Prut River are reflected in the character of materials from the sites of Sǎrǎteni, Bilichenii Vechi 12, Sacarovca 4 and Chişcǎreni 5. While their stone inventories are still typical of the Late Mesolithic, some other finds coupled with the available radiocarbon dates give grounds to think that the inhabitants of these sites co-existed and probably interacted with the Criş culture people, who were the first Early Neolithic settlers in the region.
