Attirampakkam was identified by the British geologist Robert Bruce Foote in 1863. The Indian researchers took nearly a decade of holistic study of the site to understand the archaeology in relation to paleo-environment. Among the more than 3,500 quartzite tools recovered from the site, the most common ones were the oval and tear-drop shaped bifacial hand-axes, cleavers, and small fakes (small chipped stones). Quite a number of tools discovered at the lowest buried Acheulian levels indicate that they were brought from elsewhere and only the final shaping was done at Attirampakkam. This is not unexpected: hominins using Acheulian tools were highly mobile.
