TIANJIN, Nov. 28 (Xinhua) -- More than 20 relics were recently discovered in a Paleolithic cave site in north China's Tianjin Municipality, local cultural heritage protection authorities said Thursday.
The site is located on a hill in Guoxiangyu Village, Jizhou District. Ten stone tools were unearthed in previous excavations at the entrance of the cave.
The new round of excavation was conducted by the cultural heritage protection center of Tianjin, the research center for Chinese frontier archaeology of Jilin University and the cultural relics protection and management institute of Jizhou.
Sheng Lishuang, deputy director of the cultural heritage protection center of Tianjin, said more than 100 items of stone tools and animal skeletons were unearthed in a bigger cave, while the others were found in a smaller cave.
The stone implements, including flints, blades, scrapers and drills, have been sent to professional testing institutions.
"The results will be able to tell us how old the site is," Sheng said.
