You’re next, Atlantis. Archaeologist Damian Evans and a team of researchers in Cambodia have discovered an ancient city that was hidden in the jungle for more than 1,000 years. The lost city of Mahendraparvata is 1,200 years old — 350 years older than Cambodia's treasured Angkor Wat temple complex. The settlement was part of the Hindu-Buddhist Khmer Empire that ruled much of Southeast Asia from about 800 to 1400 A.D. Archaeologists found the ruins using airborne laser mapping technology, and stunned even lifelong residents of the area, who had no idea that their dense tropical landscape hid the priceless remains of an ancient civilization.
