Archaeologists have discovered a large Old Stone Age site, dating back 10,000 to 30,000 years, in northeast China.
The ruins, covering more than 40,000 square metres, were found in a mountainous area in Kangle Village, Muleng City in Heilongjiang Province, said Ni Chunye, director of the city's administration of cultural heritage.
A total of 136 stone tools in various shapes were collected from the surface of the site, state-run Xinhua news agency reported.
The findings and geological features indicated the site belongs to the Upper Paleolithic period, said Chunye.
Of the unearthed large paleolithic sites in China, the Muleng site is furthest east, providing important evidence for research on human development, according to archaeologists.
