Ruins of 4,300-year-old prehistoric city found in China
Chinese archaeologists have discovered the ruins of a prehistoric city dating back an estimated 4,300 years in southwest Sichuan province, state press said.
The find provided evidence that the region along the upper reaches of the Yangtze River, with the Chengdu Plain at the core, played an important role in the origin and development of Chinese civilization, experts said.
The ancient city of Yandian measures 700 metres from north to south and 500 metres from east to west, the Xinhua news agency reported.
It covers an area of more than 300,000 square metres.
Chen Jian, an official with the relics and archaeological team in the Sichuan capital Chengdu City, said the site is next to a river at an elevation of three metres above the river bank.
This indicated that ancient people considered the availability of water and flood prevention when deciding where to build cities, he said.
Archaeologists unearthed a number of pieces of inscribed pottery, polished stone axes, chisels and spears at the site.
They also found chips of human skulls on the city wall but were unable to explain how they got there.
