An almost complete human skull fossil that could date back 100,000 years has been unearthed in China, state media said on Wednesday, hailing it as the greatest discovery since Peking Man.

Last month's find in Xuchang, in the central province of Henan, was made after two years of excavation just as two archaeologists were leaving for the Lunar New Year break, the China Daily said.

"We expect more discoveries of importance," Li Zhanyang, archaeologist with the Henan Cultural Relics and Archaeology Research Institute, was quoted as saying.
