The first settlement at Yorghan Tepe was founded on virgin soil during the Ubaid Period (5th millennium BCE). Since only a limited exposure was possible at Yorghan Tepe, the excavators also dug soundings at the nearby site of Kudish Saghir, where Ubaid levels were at the surface. Characteristic of this period are painted jars, double-mouthed jars with knobbed surface decoration (seen above), and baked clay tools for grinding grain. This knobbed-ware jar is from Yorghan Tepe; of the two clay mullers (grinding tools), one is from Yorghan Tepe, and one from Kudish Saghir.
