Samples of amber in western Canada containing feathers from dinosaurs and birds have yielded the most complete story of feather evolution ever seen.
leven fragments show the progression from hair-like "filaments" to doubly-branched feathers of modern birds.
The analysis of the 80-million-year-old amber deposits is presented in Science.
The find, along with an accompanying article analysing feather pigment, adds to the idea that many dinosaurs sported feathers - some brightly coloured.
