New feathered dinosaur discovered 中國又發現有羽毛的恐龍Epidexipteryx
http://news.bbc.co.uk/2/hi/science/nature/7684796.stm
The fossil of a "bizarre" feathered dinosaur from the era before birds evolved has been discovered in China.
Epidexipteryx was very bird-like, with four long ribbon-like tail feathers - probably used in display.
But the pigeon-sized creature shows no sign of the flight feathers seen in other bird-like dinosaurs, according to a report in the journal Nature.
its limbs lacked contour feathers - a feature common to most modern birds.
The discovery highlights the diversity of species present in the Middle to Late Jurassic, just before birds arose.
