BEIJING - Thousands of ancient artifacts and wooden poles more than 3,000 years old have been unearthed in China's southern Yunnan province, possibly the world's largest site of a Neolithic community, local media reported on Tuesday.

The poles, found standing 4.6 meters underground, were used as part of building structures for an ancient community that may have covered an area of 4 square km, the China Daily reported, citing Min Rui, a researcher at Yunnan Archaeological Institute, who is leading the excavation team.

The site could be older than the Hemudu community in Yuyao, in Zhejiang province, which is among the most famous in China and is believed to be the birthplace of society around the Yangtze River.

An area of 1,350 sq m has already been uncovered and excavation is ongoing.

"I was shocked when I first saw the site. I have never seen such a big and orderly one," Yan Wenming, history professor at Peking University, was quoted as saying.

Excavation began in January, but the site was actually discovered five decades ago during the construction of a canal along the banks of the Jianhu Lake, about 500 km northwest of the provincial capital Kunming.

Archaeologists have found more than 3,000 artifacts made of stone, wood, iron, pottery and bone, as well as more than 2,000 of the wooden posts.
