Lower Palaeolithic Sites: Attirampakkam, Didwana, Belan Valley, Bhimbetka, Chirki-Nevasa, Hunsgi and Krishna Valley

The Lower Palaeolithic period in India spans from approximately 2.5 million years ago to 100,000 years ago. This era is characterized by the Acheulian tradition, defined by the manufacture of bifacial handaxes and cleavers. The tools were primarily fashioned from quartzite, basalt, and limestone.

Attirampakkam, Tamil Nadu

Located in the Kortalayar River valley, this is the most important Lower Palaeolithic site in South India. It provides a long chronological sequence of human occupation. Excavations have revealed a transition from archaic handaxe industries to more refined flake-based technologies. The site is crucial for understanding the chronological depth of the Acheulian tradition in the southern peninsula.

Didwana, Rajasthan

Situated in the Thar Desert region, the site of Singi Talav near Didwana has yielded extensive evidence of Lower Palaeolithic activity. The presence of tool-bearing sediments within the Amarpura Formation provides insight into early human adaptation to arid, fluctuating environments. The industry found here is characterized by the use of quartz and quartzite for producing handaxes and cleavers.

Belan Valley, Uttar Pradesh

The Belan Valley is one of the few regions in India that provides a continuous stratigraphic sequence from the Lower Palaeolithic through the Neolithic periods. It is located in the northern fringes of the Vindhya Range. The site has provided abundant lithic evidence, including handaxes and choppers, embedded in alluvial deposits along the river.

Bhimbetka, Madhya Pradesh

Famous primarily for its rock paintings, Bhimbetka also contains extensive archaeological deposits from the Lower Palaeolithic. Excavations in the rock shelters have unearthed thousands of stone tools, including massive handaxes and cleavers. The deep deposits indicate that these shelters served as recurring habitation sites for early humans for tens of thousands of years.

Chirki-Nevasa, Maharashtra

Located in the Pravara River basin, this site is a prime example of a primary context Acheulian workshop. Large numbers of tools were found in their original location of manufacture rather than being transported by water. The abundance of waste flakes and unfinished tools allows researchers to reconstruct the specific knapping techniques used by early hominins in the Deccan Plateau.

Hunsgi and Krishna Valley, Karnataka

The Hunsgi and Baichbal valleys are renowned for their high density of Acheulian sites. The geology of this region consists of limestone, which was the primary raw material for tool production. Because limestone is more fragile than quartzite, the tools found here provide a unique look at delicate flaking techniques. The concentration of sites near seasonal water sources suggests that these populations organized their territory based on water availability and game movement.

Comparative Overview of Key Sites

Cultural and Technological Context

• The Lower Palaeolithic period in India is broadly divided into the Soanian tradition of the north and the Acheulian tradition of the peninsula. The Soanian tradition is identified by its focus on choppers and chopping tools made from river pebbles.
• In contrast, the Acheulian tradition, seen at sites like Attirampakkam and Hunsgi, is identified by the standardization of handaxes and cleavers.
• Early humans of this period were mobile hunter-gatherers. Their subsistence relied on foraging plant foods and hunting small to medium-sized game.
• The spatial distribution of these sites confirms that early populations favored river valleys and plateaus where raw materials for stone tools were naturally available.
• The Hathnora site in the Narmada Valley remains the most important site for fossil evidence. It yielded a partial hominin cranium, which is the only substantial fossil evidence from this period in India.
• This discovery confirms the presence of archaic humans in the Narmada Valley during the Middle Pleistocene.The transition from the Lower Palaeolithic to the Middle Palaeolithic is marked by the gradual replacement of large, heavy bifaces with smaller, more specialized flake tools.

This technological change occurred as hominins developed more sophisticated methods of stone reduction, such as the Levallois technique. These improvements allowed for greater efficiency in hunting and the processing of animal hides and carcasses. Most sites show a steady increase in the refinement of tools, indicating an accumulation of knowledge across generations.
