Scientists have announced the discovery of a perfectly preserved dinosaur embryo that was preparing to hatch from its egg, just like a chicken.

The embryo was discovered in Ganzhou in southern China and researchers estimate it is at least 66 million years old.

It is believed to be a toothless theropod dinosaur, or oviraptorosaur, and has been named Baby Yingliang.

Researcher Dr Fion Waisum Ma said it is "the best dinosaur embryo ever found in history".
