The people of the Palaeolithic Culture used tools and implements of stone, roughly dressed by chipping. These tools are found throughout the country excepting the alluvial plains of the Indus, Ganga and Yamuna rivers.
They were used for hunting, cutting and other purposes. Some of the important tools of the Palaeolithic Culture include hand axe, cleaver, chopper, flake, side scrapper and burin.
The hand-axe with broader butt-end and narrower working-end was used for cutting and digging purposes. The cleaver, due to its bifaced edge and transversality, proved useful in clearing and splitting objects. The chopper had unificial flanking and was used for chopping purposes.
A chopping tool, used for similar purpose as the chopper, was more effective due to its edge being sharper and bifaced. The flake was a crudely shaped tool produced by applying force on the stone.
ADVERTISEMENTS:
Side scrapper, made of a flake or blade with continuous retouch along a border, was used for scraping barks of trees and animal skins.
The burin, with the working border made by the meeting of two planes, was used for engraving on soft stones, bones or the wall of rock shelters and caves.
Examination of the soil of the Palaeolithic sites and other evidence has revealed a correlation between prevailing climates and the successive levels of tool technology that constitute the Palaeolithic.
The Rohri Hills in Jacobabad (Pakistan), located at the Indus River margins of the Great Indian Desert (Thar), contain a group of sites associated with sources of chert, a principal raw material for tool- and weapon-making.
ADVERTISEMENTS:
Evidence of these chert bands in alluvial plains, otherwise largely devoid of stones, suggests the development of Jacobabad as a major factory centre in the Palaeolithic age. Palaeolithic tools exhibit adaptations for working particular materials, such as leather, wood and bone.
