The 125-million-year-old feathered dinosaur, named Changyuraptor yangi, sported feathers over its body, including its arms and legs, which made it look as if it had two pairs of wings. [Image Gallery: Dinosaur Fossils] 
 
 The researchers estimate 4-foot-long (1.2 meter) Changyuraptor weighed about 9 lbs. "It's not known yet whether a four-wing body is something unique to microraptorines, or something the common ancestor of birds and microraptorines had, that was later lost in the bird lineage." (4 kilograms), making it the largest four-winged dinosaur found yet, and at least 60 percent larger than the largest microraptorine specimen found previously, Chiappe said. The newfound dinosaur is a microraptorine, a group of predatory, feathered dinosaurs related to Velociraptor and other well-known raptor dinosaurs. "The vast majority of feathered dinosaurs in Liaoning are collected by farmers who live there," said study author Luis Chiappe, a paleontologist and director of the Dinosaur Institute at the Natural History Museum of Los Angeles County.  The largest "four-winged" dinosaur known has been found, and this predator has the longest feathers yet outside of birds, researchers say. Its fossil was unearthed in 2012 in Liaoning province in northeastern China, which has been the center of a surge of discoveries of feathered dinosaurs over the last decade.
– Take the velociraptors made famous by Jurassic Park, make them a bit smaller, add feathers, then change the limbs to wings and you will have something resembling a newly discovered dinosaur species found in China. Researchers say Changyuraptor yangi, a carnivore that lived around 125 million years ago, has the longest feathers ever found outside birds, to which it is very closely related. It's a lot bigger than any other "four-winged" dinosaur species known, reports NBC News. Researchers compare the creature, which was around 4 feet long and weighed about 9 pounds, to "a mid-sized turkey with a very long tail" and say that while it probably couldn't fly the way modern birds do, it could flap its wings and the feathers would have helped it land safely despite its size. "So this does raise the possibility they could glide or 'fly' in a primitive sort of way," a paleontologist tells Reuters. "The way I like to think of it is: if you pushed them out of a tree, they'd fall pretty slowly." (Another newly discovered dinosaur had bony "wings" on its head.)
