XI’AN, CHINA—Live Science reports that pieces of an estimated 20 additional warriors in the Terracotta Army have been discovered in a pit situated near the tomb of Qin Shihuangdi, China’s first emperor, who died in 210 B.C. Some 2,000 terracotta warriors have been recovered from three pits unearthed about a mile away from his mausoleum, which is located in northwestern China. Archaeologists estimate there may be as many as 8,000 of them buried at the site. Most of the sculptures in the newly discovered pit represent infantry and chariots, although there are a few generals, who were equipped with more elaborate headgear than the other soldiers.
