Photographs of supposedly ancient underwater ruins off the coast of Japan, all around the Pacific, off Indonesia and Malaysia, off India, and in the Mediterranean, the Atlantic and the Caribbean by Graham Hancock. He claims to have dredged artifacts and human bones from the sea floor off India that dated to 9000 years ago.
