Feathered dinosaurs in a tangle

Abstract

A dramatic feathered dinosaur fossil from the Jurassic of China resolves a 'temporal paradox'. But it adds intriguing complications to the debates on the evolution of feathers and flight in birds. Birds are dinosaurs. That's hardly the stuff of headlines any more, as data have streamed in revealing anatomical similarities between birds and the theropod dinosaurs from the tips of their noses to the tips of their feathered tails.
