The Baghor stone from presumably one of the oldest Shakti shrines in India, and one of the oldest sites of worship yet discovered in the world, is estimated to have been formed during this period (9000-8000 BCE). However, it may predate 10,000 BCE as samples were dated to 11,870 (± 120) YBP in a 1983 publication. The living shrine at which it was found is currently used as a place of worship for Devi by both Hindus and Indian Muslims. The triangular shape of the stone is that of the Kali Yantra which is also still in use across India. The Kol and Baiga tribes consider the triangular shape to symbolise the mother goddess 'Mai', variously named Kerai, Kari, Kali, Kalika or Karika.
