Ancient Secrets Of Indy's Return
THE skulls had moving jaws and could talk and sing. But they were lost when Mayan civilisation collapsed. Some are thought to be under the sea and others in private collections.
A CRYSTAL skull of Aztec origin is kept in the British Museum. It was bought from Tiffany's in New York after being looted from an ancient site in Mexico.
A CRYSTAL skull is still used in special ceremonies by Lacandon priests who believe it can help ward off sickness and halt the deforestation of their land.
ACCORDING to an ancient Mayan legend, the world will end at midnight on December 21, 2012, unless the wisdom of the combined skulls is heeded.
