Explanation: Adichanallur:

The burial mound at Adichanallur yielded the following:

• Urns and pottery of various kinds in large numbers.
• Iron implements, including spades and weapons (daggers, swords, spears and arrows). Some stone beads and a few gold ornaments
• Bronze objects representing the domestic animals such as buffalo, goat or sheep and cock, and wild animals like tiger, antelope and elephant.
• Traces of cloth and wood.
• Paiyampalli is a village in Tirupathur taluk, Vellore district. The Archaeological Survey of India carried out an excavation in the 1960s and unearthed black and red ware pottery in this megalithic site. A large number of urn burials were also found in this region. The date of this culture, based on radio carbon dating, is 1000 BCE.
• Kodumanal, 40 km from Erode, is located on the northern bank of Noyyal River, a tributary of the Cauvery. A series of excavations were carried out during the 1980s and 1990s. The most recent was in 2012. In habitation trenches and megalithic burials of Kodumanal, the goods unearthed included pots, weapons, tools, ornaments, and beads, particularly carnelian, akin to those found at Mohenjodaro. Since carnelian was not known to this region in ancient times, it may have been brought to Kodumanal from outside.
