Protarchaeopteryx robusta, a fossil animal discovered in China, had distinct feathers, which helps substantiate the theory that birds evolved from dinosaurs. This small carnivorous ground dwelling dinosaur is more primitive than the Archaeopteryx, the earliest known bird, although its symmetrical feather structure suggests this primitive bird could not fly.
