  • Radiometric dating - The samples from Sivagalai were analyzed by three prestigious research institutions
    • Beta Analytics in the United States
    • Physical Research Laboratory in Ahmedabad
    • Birbal Sahni Institute of Palaeosciences in Lucknow.
  • Advanced dating techniques - The samples from Sivagalai, however, were subjected to advanced dating techniques
    • Accelerometer mass spectrometry radiocarbon (AMS14C) dating for charcoal
    • Optically stimulated luminescence (OLS) dating for ceramics.
  • The Report – Findings of the dating study were presented as ‘Antiquity of Iron: Recent Radiometric Dates from Tamil Nadu’, authored by K Rajan and R Sivanantham.
  • Findings - Radiometric dating of burial urn samples from Sivagalai indicate a thriving Iron Age civilization in southern India in 4th millennium BCE, contemporaneous with copper civilization of  Indus Valley.
  • While the regions to the north of the Vindhyas were still in the Copper Age, southern India may have entered the Iron Age due to a lack of commercially exploitable copper ores.
  • Adichanallur charcoal - Adichanallur in Thoothukudi district, of Tamilnadu produced a charcoal sample associated with iron objects that was dated to 2517 BCE.
  • First smelted iron - For the first time in the world, smelted iron has been dated back to the middle of the third millennium BCE.
  • Hittite Empire (in modern-day Turkey)- This was believed to be the first civilization to use iron, with evidence dating back to around 1,380 BCE.
  • Other Iron regions of India - Brahmagiri in Karnataka and Gachibowli near Hyderabad, were dated to around 2140 BCE and 2200 BCE, respectively.
