New excavation work has begun in the Zhoudkoudian caves located near Beijing, where the skulls of Peking Man were found in the 1920s and 30s. Apart from looking for new relics, one of the cave walls will be shored up to prevent possible collapse.
Researchers will excavate 20 square meters along the western wall of the site, called Locality 1, Gao Xing, deputy director and research fellow of the Chinese Academy of Sciences Institute of Vertebrate Paleontology and Palaeoanthropology, said yesterday.
Locality 1, where the first complete skull of Peking Man was found, used to be a 20-meter-wide, 140-meter-deep cave, but the ceiling collapsed. The four-month project aims to protect the western wall from further collapse, he said.
