This illustration provided by Dinostar Co. Ltd. shows the dinosaur, Yi qi, which is Mandarin for "strange wing." Dinosaurs normally used feathers for flight, but the newly discovered creature evidently had wings made of skin instead, like a bat's, described in a paper released by the journal Nature on Wednesday, April 29, 2015. Though it's not clear whether they flapped or merely let the creature glide.

NEW YORK — A pint-sized dinosaur has a big surprise: It apparently sported a pair of bizarre wings.

Dinosaurs normally used wings mostly made of feathers for flight. But the newly discovered creature evidently had wings made of skin instead, like those of a bat or some ancient flying reptiles.

It's not clear whether they flapped or merely let the creature glide.

A fossil of the two-legged dinosaur was reported Wednesday in the journal Nature. The creature weighed less than a pound when it lived in northeast China some 160 million years ago. The Chinese researchers named it Yi qi, (ee chee), which is Mandarin for "strange wing."

The evidence for the wings comes from bones extending from the wrists like rods, plus some patches of skin.
