Beijing, June 30: The mummified remains of a middle-aged man, believed to be 1,700 years old, have been unearthed on a less frequented section of the ancient Silk Road on the edge of Chi’s Qinghai-Tibet plateau. The body was found at a construction site in the town of Mang’ai, reports Xinhua news agency. “It is in good shape, perhaps the oldest and the best preserved mummy discovered on the Qinghai-Tibet Plateau,” a senior official said. The body measures 1.62 metres, and features perfectly preserved skin and hair remnts. The man was believed to be in his 40s when he died. His hands are crossed over the abdomen.
