In a modest-sized university lab in the southern Indian state of Tamil Nadu, researchers are using a tiny drill to scrape away enamel from a 2,500-year-old tooth, BBC reported.
Researchers at Madurai Kamaraj University say the tooth belongs to one of two human skulls that they have used as models to digitally reconstruct faces to understand what the region's early inhabitants might have looked like.
The skulls, both belonging to men, were excavated from Kondagai, an ancient burial site about 4km (2.5 miles) from Keeladi - an archaeological site that has become a political flashpoint in India.
Tamil Nadu state department archaeologists say an urban civilisation dating back to 580BC existed in Keeladi, a claim that adds a new dimension to the story of the Indian subcontinent, according to BBC.
