Archaeologists S. Rama Krishna Pisipaty and S. Shanmugavelu have researched what may be a key site in a dry lake bed at Singadivakkam, a village some 65 km south of Chennai (Madras). The site is known as Kancheepuram.
The site has so far provided some 200 tools and, crucially, it seems to have no disruption from the Lower Paleolithic (thought to be work of H. erectus) and the Middle Paleolithic (maybe work of H. sapiens), unlike all other sites in the subcontinent. The tools found include hand axes, borers, scrappers, choppers and pointed tools, as well as microliths.
Kancheepuram was ideal for early settlers with its large number of safe water bodies a lifeline for any human settlement, said Pisipaty.
