The next stage of human life is called Mesolithic or Middle Stone Age which falls roughly from 10000 B.C. to 6000 B.C. It was the transitional phase between the Paleolithic Age and Neolithic Age. Mesolithic remains are found in Langhanj in Gujarat, Adamgarh in Madhya Pradesh and also in some places of Rajasthan, Utter Pradesh and Bihar. The paintings and engravings found at the rock shelters give an idea about the social life and economic activities of Mesolithic people.

In the sites of Mesolithic Age, a different type of stone tools is found. These are tiny stone artifacts, often not more than five centimeters in size, and therefore called microliths. The hunting-gathering pattern of life continued during this period. However, there seems to have been a shift from big animal hunting to small animal hunting and fishing. The use of bow and arrow also began during this period. Also, there began a tendency to settle for longer periods in an area. Therefore, domestication of animals, horticulture and primitive cultivation started. Animal bones are found in these sites and these include dog, deer, boar and ostrich.

Occasionally, burials of the dead along with some microliths and shells seem to have been practiced.
