Chinese paleontologists discovered a giant 1,400 kg (3,086 lb) "Big Bird" dinosaur they named Gigantoraptor:
Gigantoraptor is about 300 times as heavy as primitive feathered peers already known to science. [..]
The big, bird-like dinosaur would have stood, at the shoulder, twice the height of a man, with feathers at least on its arm and tail, and probably grew much faster than the likes of Tyrannosaurus Rex.
