Sarutaru site

Sarutaru is a prominent Neolithic site located in the Kamrup district of Assam, Northeast India. Situated on the top of a small hillock along the foothills of the Khasi hill range, it lies close to the border dividing Assam and Meghalaya. This positioning places Sarutaru in a critical ecological zone—a river valley-hill slope interface characterized by heavy monsoonal precipitation, dense tropical vegetation, and rich riverine alluvial soils along the foothills. Excavated in the early 1970s by archeologists from Gauhati University, Sarutaru provided invaluable data regarding the spatial distribution of early farming communities in Northeast India. It demonstrated that Neolithic populations were not restricted to deep hill interiors like Daojali Hading but actively exploited the foothill zones connecting the plains with the mountains.

The Neolithic Phase at Sarutaru

The occupational strata at Sarutaru reveal a well-defined, unstratified Neolithic deposit that offers a clear look into the material culture of the region’s early food-producing societies.

Lithic Technology: Shouldered and Rounded Celts

The stone tool kit discovered at Sarutaru is dominated by ground and polished implements, showcasing an advanced stage of stone-working designed for clearing forests and processing plants.

• Shouldered Celts: Like other major Northeast Indian sites, Sarutaru yielded distinct shouldered axes (adzes). These feature a carved tenon or shoulder at the butt end, enabling secure attachment to split-wooden or bamboo shafts.
• Rounded-Butt Celts: The site is also notable for producing small, rounded-butt stone axes with oval cross-sections. These tools are highly polished, particularly near the cutting edges.
• Raw Materials: The tools were fashioned primarily from locally available metamorphic rocks, specifically slate and fine-grained sandstone, indicating an efficient adaptation to regional resources.

Ceramic Tradition: Coarse Corded Ware

The ceramic industry at Sarutaru is entirely handmade and shares strong cultural characteristics with the broader East Asian Neolithic complex.

• Surface Treatment: The dominant ceramic type is coarse, handmade Cord-Marked Pottery. The exterior walls of the vessels feature distinct impressions of twisted vegetable fibers, cords, or woven mats.
• Fabric and Color: The pottery paste was tempered with coarse sand and crushed quartz to withstand thermal shock during open-fire cooking. The color spectrum of the recovered potsherds ranges from a dull brown to a dark brownish-grey.
• Vessel Typology: The forms are predominantly utilitarian, consisting of round-bottomed vessels and wide-mouthed pots used for boiling food and storing resources.

Subsistence and Shifting Agriculture

Organic remains like animal bones and plant matter degrade rapidly in the highly acidic, monsoonal soil of the Kamrup foothills. However, the presence of specialized tools provides indirect proof of the economic patterns:

• Jhum (Slash-and-Burn) Cultivation: The edge-wear on the heavy polished stone axes indicates they were used to fell trees and clear bamboo groves for shifting hill cultivation.
• Staple Economy: The agricultural strategy relied heavily on the cultivation of primitive strains of rice (Oryza sativa), supplemented by the foraging of wild yams, taro, and tubers.

The Question of Copper-Bronze (Chalcolithic) and Iron Age Transitions

Sarutaru’s stratigraphic placement helps clarify the technological transitions of Northeast Indian prehistory.

The Bypassing of the Chalcolithic Era

Excavations at Sarutaru show a total absence of a copper-bronze or Chalcolithic horizon. The Neolithic layers do not yield any evidence of local copper metallurgy or trade links with the copper-producing centers of central or western India. Due to ecological barriers and regional isolation, the site bypassed the Bronze Age entirely.

Transition to the Iron Age and Megalithic Horizon

The Neolithic material culture at Sarutaru and its surrounding landscape transitioned directly into an overlapping Megalithic and Early Iron Age horizon during the 1st millennium BCE.

• Megalithic Affiliations: The hills surrounding Sarutaru feature extensive non-sepulchral Megalithic structures, such as upright menhirs (Mawbynna), erected by ancestors of the local Khasi-Jaintia populations.
• Iron Implements: The eventual introduction of iron tools (such as socketed hoes, sickles, and heavy axes) allowed later generations to clear the heavy sub-montane forests far more efficiently than the Neolithic stone celts permitted, leading to stable, long-term village settlements in the valley corridors.
