In view of the post-diagenetic changes of flood-plain silts capping the Boulder Conglomerate (Gravel I) of the Lower Narmada Group and the occurrence of a few mammalian species in the Boulder Conglomerate like *Hexaprotodon sivalensis* (Dassarma and Biswas, 1978) which are totally absent in the Upper Group, it appears that the Boulder Conglomerate/Red Clay has a far greater antiquity than the Upper Group. Thus the Lower Group could be tentatively dated as late Middle Pleistocene to early Upper Pleistocene (150000 to 40000 B.P.). The Stone Age tools found in the Boulder Gonglomerate belong to this period and therefore represent one of the earliest remains of Stone Age Man in peninsular India.
