Key Facts

  • Gudiyam Survey (Tiruvallur, TN): Prehistoric activity recorded at 18 of 40 surveyed sites over four months.
  • Early Iron Age Art: Rock paintings (>3,000 years old) depicting human figures and geometric patterns found at Kuralchavadu Sunai, Pasumaadu Parai, and Kannithoppu.
  • Vavaal Cave & Inscription: Documented an 11.87-metre tunnel-like cave and a ~700-year-old 14th-century inscription noting spring excavation by carpenter Veera Gangathattan.
  • Ancient Food Culture: Pottery residue analysis from Keeladi (6th–2nd century BCE) and Gottiprolu (2nd–1st century BCE) revealed cow milk consumption and plant processing (including groundnut-linked organic residues at Keeladi) from 600 to 100 BCE.

GK Context

  • Gudiyam Caves are famous: Palaeolithic–Iron Age rock shelters located near Poondi in Tiruvallur district, first excavated by the ASI in the 1960s (K.D. Banerjee).
  • Keeladi (Sivaganga district, Vaigai: river valley) is a major Sangam-era urban settlement excavated since 2014–15, pushing back Tamil urbanism and literacy to at least the 6th century BCE.

Static GK

  • Gottiprolu: Early Historic fortified settlement in Tirupati/Nellore region of Andhra Pradesh excavated by the Archaeological Survey of India (ASI).
  • Palaeolithic sites in Tamil Nadu: Attirampakkam (Tiruvallur), Gudiyam, Pallavaram (discovered by Robert Bruce Foote in 1863).

Mains Analytical Framework

  • Scientific Archaeology in South India: Biomolecular and lipid residue analysis of pottery transforms understanding of Sangam-age diet, pastoralism, and trade.
  • Heritage Conservation: Documenting fragile rock-art sites like Gudiyam inside forest areas requires joint ASI–Forest Department protection.
