Carbon dating quartz

The anatomically completely accurate skull, with its separate mobile lower jaw was carved from one whole piece of quartz crystal.Anna Mitchell Hedges wished to discover who made the skull, and when, and gave it to the world-renowned company Hewlett-Packard for testing.On 1 January, 1924, Canadian Anna Mitchell Hedges discovered a crystal skull beneath an alter in a pyramid temple in the lost Mayan city of Lubaantun (meaning the city of the fallen stones in the Mayan language).

Because all dating techniques may be subject to considerable error, reliability should be assessed by stratigraphic consistency between results of different dating methods or of the same method.Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.The majority of the time fossils are dated using relative dating techniques.Using carbon dating, they estimate that most of the samples are close to 11,000 years old—the oldest bed-bug samples ever found—which coincides with when the first humans were starting to arrive in North America.Their work was published in the Journal of Medical Entomology on April 4.

Since the crystal contained no carbon, scientists were unable to perform radio-carbon dating, but used different techniques to try to establish when the skull had been made, and using which methods.1.
