Until the publication of Professor Xu Xing's findings this week in the journal Nature, the last living dinosaur discovered with feathers was the Beipiasaurus,
which lived about 125 million years ago. Now Xing's newest feathered
discovery, found in the same region of Liaoning Province in China, is
about 40 times larger than the man-size Beiplasaurus, and has been named Yutyrannus huali, "beautiful feathered tyrant."
