Konkan geoglyphs

The thousands of Mesolithic-to-Chalcolithic rock carvings (geoglyphs) etched into the laterite plateaus along the Konkan coast of Maharashtra and Goa, from Ratnagiri south through Sindhudurg. Over 1,500 geoglyphs documented since 2012 by Sudhir Risbud's grassroots survey show animals (tiger, deer, buffalo, elephant, rhinoceros, extinct megafauna), human figures and abstract geometric forms carved up to 20 metres long on the open laterite — some of the largest prehistoric rock art in the subcontinent. Dates range from 10,000 BCE to 2500 BCE. The geoglyphs are under threat from quarrying and road-building; UNESCO tentative list since 2022.
