Prehistoric India to 1000 B.C. c9.4

c9.4

The whole of this epoch constitutes the major geological division of the Quaternary Period and the sub-division known as the Pleistocene phase. Archaeologically the human remains and tools from Pleistocene deposits are classed together as the Palaeolithic or Old Stone Age phase of man’s development, and both the Pleistocene and the Palaeolithic are further divided into two major subdivisions, Lower and Upper. But there are other important subdivisions of the Pleistocene geological sequence, linked to those fluctuations in solar radiation already mentioned.
