In terms of Palaeolithic studies, the Mehran Plain is already known due to the discovery of the Amar Merdeg site in 1999. But in spite of the high potential for occupation in different periods, the prehistoric settlement patterns of the plain had not been identified until the present survey in 2010, which resulted in the discovery of 15 Palaeolithic sites. Of these, 9 sites contain both Lower and Middle Palaeolithic remains and 3 more sites are attributed to the Middle Palaeolithic as well 3 sites to Upper Palaeolithic period and beyond. The distribution pattern indicates that easy access to raw materials, which are now visible among the chert pebbles scattered over hillocks on the plains, was the main reason to establish settling.
