Yixianosaurus

Yixianosaurus (meaning "Yixian lizard") was a maniraptoran dinosaur genus from the Early Cretaceous (Aptian stage, 122 million years ago) of China. It is known only from a pair of fossilized arms complete with fossilized feathers. Its exact placement within Maniraptora is uncertain, though its hands resemble those of another feathered dinosaur, Epidendrosaurus.

The type species, Yixianosaurus longimanus, was formally described by Xu X. & Wang Xiao-lin in 2003. The partial skeleton was recovered in Liaoning, in northeastern China.
