sites in Bihar, West Bengal and Orissa. Its
industry, bone tools and worked antler pieces, semi-precious stone beads,
reed and mud houses, rice as the principal crop, miscellaneous terracotta and
stone objects. In Orissa this level has not yet been extensively excavated, but
in Bihar and West Bengal there are very large number of sites.
    • There are 70-odd reported Chalcolithic and Iron Age Black-and-Red
        Ware sites in West Bengal. What is interesting is that, with the
        exception of Bangarh in the Barind plain of the northern part of the
        state, which shows only a piece of this pottery on the surface, they are
        distributed mostly in the area to the west of the Bhagirathi.
    • The most impressive evidence of crops has occurred in the
        Chalcolithic context at Senuar—rice, barley, wheat, sorghum, millet,
        peas, lentil, sesamum and linseed. On the whole, the Neolithic–
        Chalcolithic assemblage of the Gangetic plains of Bihar is remarkably
        interesting. From approximately the middle of the third millennium BC
        there were fully agricultural and pre-metallic villages with a wide
        range of crops, on the river banks of a substantial area of Bihar.
Uttar Pradesh
In eastern UP the protohistoric evidence in the northeastern segment of the
trans-Sarayu plain which touches the area of ancient Kapilavastu is not
particularly clear except that the Piprahwa- Ganwaria excavations have
isolated a deposit of Black-Slipped and Grey Wares. Another fixed point of
the protohistoric archaeological sequence of the trans-Sarayu plain has been
obtained at Imlidih, Narhan and Sohgaura in the southern segment of the
region. Narhan lies straight on the northern bank of the Sarayu; Imlidih is on
the bank of the Kuwana whereas Sohgaura lies at the junction of the Ami and
the Rapti.
                              OCP CULTURE
  In western UP village life begins with the Ochre Coloured Pottery (OCP)
  level and the ‘late Harappans’, if not with the end phase of the mature
  Harappan itself. The easternmost occurrence of the OCP level is at
  Sringaverapura near Allahabad, whereas the late Harappan distribution
