Xiaochangliang
Xiaochangliang () is the site of some of the earliest paleolithic remains in East Asia, located in the Nihewan Basin in Yangyuan County, Hebei, China, most famous for the stone tools discovered there.
==Stone tools==
The tool forms discovered include side and end scrapers, notches, burins, and disc cores. 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.
