LHASA, Aug. 10 (Xinhua) -- More than 60 artifacts thought to be around 2,000 years old have been found in ancient tombs in southwest China's Tibet Autonomous Region, local authorities said Friday.

Researchers found the artifacts at two tomb sites in Zanda County of Ngari Prefecture after two months of excavation. There are more than 10 ancient tombs at the two sites, according to the local cultural heritage department.

"The artifacts include pottery, bronzeware, goldware and accessories, and are similar to findings at another site in Ngari dating back around 2,000 years," said Loden, head of the county cultural heritage department.

Further confirmation of the age of the artifacts is underway at the regional cultural heritage institute.

"The artifacts offer important evidence for studying the early culture in western Ngari," said Shaka Wandu, assistant researcher at the regional institute.
