Shuvuuia is a genus of bird-like theropod dinosaur from the late Cretaceous period of Mongolia. It is a member of the family Alvarezsauridae, small coelurosaurian dinosaurs which are characterized by short but powerful forelimbs, possibly specialized for digging. The type (and only known) species is Shuvuuia deserti, or "desert bird". The name Shuvuuia is derived from the Mongolian word shuvuu meaning "bird". The fossil of Shuvuuia has feather traces, proving that Alvarezsauridae were among the theropod lineages with feathery or downy integument.
