About 120 million years ago, during the Early Cretaceous, a small dinosaur called Microraptor lived in what is now Liaoning, China. Its body carried long feathers not just on its arms, but also on its legs, giving it a strange four-winged design unlike anything seen in the same way today. Those feathers likely helped it glide, and some later studies have even suggested it may have been capable of powered flight.
