A huge flightless bird/dinosaur fossil has been unearthed in China. From the USA Today story by Calum MacLeod:

BEIJING — The dinosaur world's latest star had a toothless beak, waved feathered arms incapable of flight and may have hunted only plants. But if you met Gigantoraptor erlianensis in a Mongolian forest 70 million years ago, best to have given it a wide berth. At more than 16 feet tall and roughly 3,000 pounds, the beast could stand eyeball-to-eyeball with a tyrannosaur, Chinese researchers say.

According to the paper in Nature, this find remarkably resembles other finds where feathers are present, hence the designation. It is awfully big to have feathers, though.
