Attirampakkam, or Athirampakkam is a village near river Kortallaiyar located 60 kilometers away from Chennai, Tamil Nadu, India. [1] [2] The oldest stone tools in India were discovered near the village, [3] [4] which became the type site for the Madrasian culture. [5] [6]
Robert Bruce Foote and his colleague William King of the East India Company's Geological Survey found the first primitive stone tools at Attirampakkam in early 1863. Later, more stone tools were recovered from Attirampakkam over 20 years by archaeologists from the Sharma Centre for Heritage Education in India and other Indian institutions. [7] Due to lack of any hominine fossils or bones recovered yet from the site or South Asia as a whole, it is currently impossible to conclude which hominin species had created these tools. [7]
With the assistance of French scientists, the age of the objects found in the trenches was determined using cosmic ray exposure dating (26Al/10Be). [8] It was the first time in India, the archaeological site in India was dated. By performing a luminescence dating method called Post Infrared Stimulated Luminescence (pIR-IRSL) on about 7,200 artifacts found at Attirampakkam, researchers have made a chronology of Attirampakkam stone tool technology with a span of about 200,000 years. [9] Latest studies indicate that the Levallois technology used at Attirampakkam emerged about 385,000 (± 64,000) years ago, at a period when processes signifying the end of the Acheulian culture occurred and a Middle Palaeolithic culture had emerged.
