Although it is generally more difficult to date Asian sites than African sites because Asian sites typically lack volcanic materials that can be dated isotropically, the age of the tools has been magnetostratigraphically dated as 1.36 million years. This method hinges upon dated reversals in the Earth's magnetic field.
