Baby bird fossil is 'rarest of the rare'
Scientists have unveiled one of the smallest bird fossils ever discovered.
The chick lived 127 million years ago and belonged to a group of primitive birds that shared the planet with the dinosaurs.
Fossils of birds from this time period are rare, with baby fossils seen as "the rarest of the rare".
Scientists say the discovery gives a peek into the lives of the ancient, long-extinct birds that lived between 250 and 66 million years ago.
