Yutyrannus

Feathers preserved around the skeleton of Yutyrannus huali make it the largest feathered dinosaur yet found, at roughly 9 meters and near 1,400 kilograms. Its name means beautiful feathered tyrant. As an early member of the tyrannosaur lineage from the Early Cretaceous of China, roughly 145 to 100 million years ago, this carnivore shows that even large-bodied tyrannosaurs could bear a coat of filament-like feathers, challenging the assumption that big theropods had bare, scaly skin. Xu Xing and colleagues described it in 2012 from Liaoning Province, and its discovery reshaped debate over how widespread feathers were among giant predators.
