Late Cretaceous feathers in amber
Samples of amber in western Canada containing feathers from dinosaurs and birds have yielded the most complete story of feather evolution ever seen.From the BBC.
Eleven 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.
