尾羽龙

董氏尾羽鸟（Caudipteryx dongi）是一种体型与孔雀相当的驰龙科恐龙，生活于白垩纪早期（1.246亿年前）。它们全身长满羽毛，整体外形极其像鸟类。 该物种的化石最初是在中国东北辽宁省四平市义县组地层中发现的。据推测，董氏尾羽鸟是一种杂食性动物。

Caudipteryx dongi is a genus of peacock-sized oviraptorid dinosaur that lived in the early Cretaceous Period (124.6 million years ago). They were feathered and remarkably birdlike in their overall appearance. Fossils were first discovered in the Yixian Formation of the Sihetun area of Liaoning Province, northeastern China. Caudipteryx is thought to have been an omnivore.
