 | In 2015 scientists unearthed a spectacularly preserved, nearly complete fossil in northeastern China of a feathered dinosaur with wings like those of a bird, although they doubt the strange creature could fly. The researchers said the fast-running meat-eater was about 6 feet (1.8 meters) long and covered with simple hair-like feathers over much of its body, with large, quill-like feathers on its wings and long tail. Finding the dinosaur raises questions about why wings evolved in the first place. |
 | The largest-known dinosaur with wings, it lived about 125 million years ago during the Cretaceous Period. Paleontologists dubbed the dinosaur, named Zhenyuanlong suni, a "fluffy feathered poodle from hell." Birds evolved from small feathered dinosaurs. The oldest-known bird, crow-sized Archaeopteryx, lived about 150 million years ago. |  |
