State-run media in China reports a construction crew working at Beijing's main airport has unearthed the fossilized bone of an elephant that roamed the area 30,000 years ago.

The Xinhua news agency quotes a spokesman for the Beijing Natural History Museum as saying the thigh bone belonged to a palaeoloxodon, which once lived in throughout parts of modern-day China.

The discovery came as construction workers continued building a new terminal for Beijing's main airport ahead of the 2008 Summer Olympics in the Chinese capital.

According to the report, a complete palaeoloxodon skeleton was once discovered in China's northern Hebei province.
