The only relevant excavated site in this region is Saraikhola whose Period I has ground stone celts, terracotta wheels and toy-cart frames, microlithic tools, bone points, handmade pottery with basketry-impressed base, and no metal. The transition to Period II was gradual, handmade pottery being replaced with wheelmade type. An example of this kind was a red jar with a short neck and a large elliptical/ovoid body, and painted black at the neck and shoulder. This is a typical ‘Kot Diji’ form, more of which has been found in this period, along with some copper, terracotta and shell bangles, microlithic and ground stone artefacts, terracotta cattle figurines, toy-cart frames, sling pellets, stone beads, etc. There is no radiocarbon date but Period II should belong to the second half of the third millennium BC.
