Dinosaurs had feathered, chestnut brown tails with a pale underside, a newly found specimen reveals.
The tip of the tail was found preserved in an ancient blob of amber tree resin.
It belonged to a small, flightless dinosaur that lived in the mid-Cretaceous period around 99 million years ago.

Tyrannosaurus rex, one of history?s most dreaded carnivores, had an odd-looking vegetarian cousin with a tiny head, long neck and stubby fingers, scientists said April 27, admitting its anatomy had them puzzled.
