The earliest settled portion of Mehrgarh is found in an area called MR.3, in the northeast corner of the immense site. Mehrgarh was a small farming and pastoralist village between 7000-5500 BC, with mud brick houses and granaries. The early residents used local copper ore, basket containers lined with bitumen, and an array of bone tools.
Plant foods used during this period included domesticated and wild six-rowed barley, domestic einkorn and emmer wheat, and wild Indian jujube (Zizyphus spp) and date palms (Phoenix dactylifera). Sheep, goats, and cattle were herded at Mehrgarh beginning during this early period. Hunted animals include gazelle, swamp deer, nilgai, blackbuck onager, chital, water buffalo, wild pig and elephant.
The earliest residences at Mehrgarh were freestanding, multi-roomed rectangular houses built with long, cigar-shaped and mortared mudbricks: these structures are very similar to Prepottery Neolithic (PPN) hunter-gatherers in early 7th millennium Mesopotamia. Burials were placed in brick-lined tombs, accompanied by shell and turquoise beads. Even at this early date, the similarities of crafts, architecture, and agricultural and funerary practices indicate some sort of connection between Mehrgarh and Mesopotamia.
