Description

In this National Geographic News article, read about the discovery of a 90-million-year-old skeleton of a rooster-size feathered dinosaur. The fossil's absence of true wings suggests that flight might have evolved separately in reptiles and birds. Links to other stories, photos, videos and Web sites are also found on this page.
