Two animal teeth with man-made holes came to light after having been buried for 72 straight years among other relics in the cave of Beijing Man (formerly called Peking Man) at Zhoukoudian, 48 kilometers southwest of Beijing.
The animal teeth could be decorations belonging to the Beijing Man living approximately 500,000 years ago, said Yang Haifeng, director of Beijing Man Relics Site Management Office.
Experts also discovered fossils of 12 rabbit skulls and more than 70 pieces of rabbit shanks and 40 rabbit jaw bones.
The two animal teeth with man-made holes and 12 rabbit skulls were believed to be sorted out by Pei Wenzhong, a forerunner on Beijing Man studies, in 1933. The relics then were stored aside because of ensuing wars.
The Office has all along been looking for fossils of the Beijing Man. The relics are expected to be displayed at the newly built Zhoukoudian Relics Museum.
The discovery of the 500,000-year-old Beijing Man was one of the most decisive steps in the scientific quest to trace man's prehistoric development from the apes.
