Weighing in at one and a half tons, tip-to-tail as long as a school bus, and sporting an impressive coat of feathers. Now that's a big bird.
Yesterday, scientists announced the discovery of Yutyrannus (or "beautiful feathered tyrant"), the largest feathered animal known to man. We know smaller theropods like Velociraptor had feathers and we've even been able to discern the colors and patterns in their down, but Yutyrannus (who lived long before T. rex, in the early Cretaceous) is the first evidence of fully feathered dinosaurs on a large scale. Even terror bird would have bowed to the beautiful feathered tyrant.
