பெருங்கற்காலக் கற்பதுக்கைகள் – தொல்லியல் கள ஆய்வு

This researcher has done a field work in megalithic cist at thadagam in periyanayakam palayam panchayat and found a sample of urns, graffiti marks and symboled  earthen  pots, carnealian beads, human bones  and pot stand which was very well used by our ancient Tamil people since megalithic stone age. The basic research which was done in the surface level resulted in findings of many artefacts. Hence the researcher insists and requests the Tamil Nadu Archaeological department to do further excavation to find more artefacts.
