概览
此内容目前仅提供英文版。
Yutyrannus huali lived in north-eastern China in the Early Cretaceous, in the Yixian Formation of Liaoning. Xu Xing and colleagues named it in 2012 from three nearly complete skeletons of two growth stages, said to come from a quarry near Batuyingzi, Beipiao.
It was a primitive relative of Tyrannosaurus, with a skull like later tyrannosauroids but three fingers on each hand. All three skeletons show long, simple filamentous feathers, up to about 20 cm long, on several parts of the body.
It was the first direct evidence that a gigantic dinosaur was extensively feathered, which opened the question of whether later giant tyrannosaurs such as T. rex also had feathers. The Yixian climate is reconstructed as relatively cool, which may have favoured an insulating coat.
名称含义
"Beautiful feathered tyrant", from Mandarin yǔ ("feather") and Greek tyrannos ("tyrant"), with huáli ("beautiful") for the plumage (Xu et al. 2012).

新陈代谢
The feathers of Yutyrannus helped it keep warm in a cool climate.
证据等级:假说The Yixian climate is reconstructed as relatively cool; insulation is one possible function of the feathers, display is another.
