Still Waters Posted January 13, 2009 #1 Share Posted January 13, 2009 The earliest dinosaur feathers were probably used for visual display, according to a new study. The evidence comes from two 125-million-year-old dinosaur fossils unearthed in north-east China. Writing in PNAS journal, the team says its findings may shed light on the origin of feathers. They identified a previously unknown type of feather on the specimens which, they argue, could not have been used either for flight or for keeping warm. The two specimens belong to the genus Beipiaosaurus, a member of the theropod group of dinosaurs. The study was led by Xing Xu, a palaeontologist from the Chinese Academy of Sciences in Beijing.
