An tomb dating back some 2,000 years has been found in Northwest China's Qinghai province, local authorities said Thursday.

The tomb was discovered by a construction team on Nov 23 in a village of Datong Hui and Tu autonomous county, according to Chen Rong, deputy head of the county's cultural relic management bureau.

The occupant of the tomb was confirmed as a male around 50 years old. Alongside this complete skull, cultural workers also found bricks and pottery that date the tomb to the Han Dynasty (206 BC - 220).

Chen said, it was the tomb of a rich man, but his identity remains unknown.

He added that the eastern Qinghai, where Datong is located, is an important gateway linking China's inland and western regions, so further excavation and confirmation of the occupant's identity will contribute to the study of cultural exchange between the two areas during the Han Dynasty.
