A variety of crystal skulls have been discovered in parts of Mexico and Central America, most of them composed of clear rock quartz crystal. The exact purpose and origin of the skulls has yet to be confirmed but it is thought that if genuine they would have had some religious significance to the people who created them, mainly because most of them have been found in tombs. At present around 50 of them have been found.
In 2008 the crystal skulls were brought to a wider audience when they were featured in the fourth Indiana Jones movie. More recently it was revealed that the studies of some of the skulls seemed to suggest that there were created in the 19th century and weren't thousands of years old as previously thought. The exact origins and purpose of the skulls remains something of a mystery.
