ZHENGZHOU, Dec. 15 (Xinhua) -- Archaeologists have discovered over 40 ruin sites, 60 caves and more than 200 stone artifacts dating back to the Paleolithic Age in the city of Pingdingshan, in central China's Henan Province.

The unearthed relics are believed to belong to the early and middle stages of the Paleolithic Age, based on the characteristics of the artifacts, including chipped stone tools collected from the sites, according to the archaeological team.

The discovery will facilitate research on the relationship between cultural exchange and environmental change during the period, according to the team.

The warm-and-humid climate in Lushan, together with its abundant rainfall, made the place inhabitable for ancient people, said Zhao Qingpo, head of the team.

Started in 2019, the investigation into the Paleolithic cultural relics in Lushan is expected to offer information on the early and middle periods of the Paleolithic Age and the existence of early modern human beings, said Zhao. Enditem
