Last year, Xu discovered another species of four-winged dinosaur, also at Liaoning.

Most of them came from the north-eastern province of Liaoning and the capital city of Beijing.

The Olympic torch starts its 3-day relay in Liaoning today.

I was born and brought up in northeast Liaoning, and I thought I might encounter difficulties in the heat of Sichuan.

Then came evidence, thanks to a series of astonishing discoveries in China's Liaoning province over the past five years, that some dinosaurs may have borne feathers.
