added by archaeologs A complex of Neolithic settlements on the Bosnia River near Sarajevo, Bosnia. Obre I comprises four occupation horizons, the first with Starcevo pottery, dating c 4500-4200 BC. It has rectangular houses similar to those at Karanovo I and Anza, and arranged in rows. Obre II represents the most complete development of the Butmir culture yet discovered, with nine habitation horizons in three main periods (dated c 4250-3950 BC, c 3900 BC, and c 3800 BC). This 1300-year cut through the Bosnian Neolithic sequence provides details on the evolution of timber-framed architecture, subsistence economy, and exchange systems. The pottery is interpreted as reflecting possible transhumant pastoralism.
