8,000-year-old shell mound unearthed

Archaeologists have discovered a prehistoric shell mound that is 8,000 years old at the Jingtoushan ruins in Zhejiang province, they announced on Saturday. The ruins, in Ningbo, were discovered in 2013 during a drilling survey to prepare for the construction of a factory. Archaeologists later identified the site as the earliest and most deeply buried shell mound site in coastal China. Tests by the carbon-14 lab at Peking University concluded the site was between 7,800 and 8,300 years old. A large number of exquisite artifacts such as pottery and stone tools, along with animal remains, have been unearthed since digging began in September.
