In India, the prehistoric period is divided into the Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), Neolithic (New Stone Age) and the Metal Age. However, these periods were not uniform throughout the Indian subcontinent. The dating of the prehistoric period is done scientifically. The technique of radio-carbon dating is commonly used for this purpose. It is based on measuring the loss of carbon in organic materials over a period of time. Another dating method is known as dendro-chronology. It refers to the number of tree rings in wood. By counting the number of tree rings in the wood, the date of the wood is arrived at.
Paleolithic or Old Stone Age
The Old Stone Age sites are widely found in various parts of the Indian subcontinent. These sites are generally located near water sources. Several rock shelters and caves used by the Paleolithic people are scattered across the subcontinent. They also lived rarely in huts made of leaves. Some of the famous sites of Old Stone Agein India are:
a. The Soan valley and Potwar Plateau on the northwest India.
b. The Siwalik hills on the north India.
c. Bhimpetka in Madhya Pradesh.
d. Adamgarh hill in Narmada valley.
e. Kurnool in Andhra Pradesh and
f. Attirampakkam near Chennai.
In the Old Stone Age, food was obtained by hunting animalsand gathering edible plants and tubers. Therefore, these people are called as hunter-gatherers. They used stone tools, hand-sized and flaked-off large pebbles for hunting
animals. Stone implements are made of a hard rock known as quartzite. Large pebbles are often found in river terraces. The hunting of large animals would have required the combined effort of a group of people with large stone axes. We have little knowledge about their language and communication. Their way of life became modified with the passage of time since they made attempts to domesticate animals, make crude pots and grow some plants. A few Old Stone Age paintings have also been found on rocks at Bhimbetka and other places. The period
before 10000 B.C. is assigned to the Old Stone Age.
