"An ancient feathered creature dug up in northeastern China is the largest winged dinosaur ever found, researchers say.
The fossil of the prehistoric raptor is so well preserved that scientists have been able to reconstruct its impressive plumage, from the tiny feathers on its head and neck, to the larger quill pen-like feathers that sprout from its tail and substantial wings."
"The specimen poses a conundrum for researchers, because despite its impressive wings, the animal was probably incapable of flight. Brusatte said their function was a mystery, but they might have been used in colourful sexual displays, just as peacocks parade their tail feathers to court peafowls. Another possibility is that the dinosaur used its wings to protect its eggs."
