Description The feathered raptor

Microraptor (Greek , μικρός, mīkros: "small"; Latin , raptor: "one who seizes") is a genus  of small, four-winged dromaeosaurid  dinosaurs . Numerous well-preserved fossil  specimens have been recovered from LiaoningChina . They date from the early Cretaceous  Jiufotang Formation  (Aptian  stage), 125 to 120 million years  ago. Three species have been named (M. zhaoianus, M. gui, and M. hanqingi), though further study has suggested that all of them represent variation in a single species, which is properly called M. zhaoianus. Cryptovolans, initially described as another four-winged dinosaur, is usually considered to be a synonym of Microraptor.[2]

Like Archaeopteryx , well-preserved fossils of Microraptor provide important evidence about the evolutionary relationship between birds  and earlier dinosaurs. Microraptor had long pennaceous feathers  that formed aerodynamic surfaces on the arms and tail but also on the legs. This led paleontologist Xu Xing  in 2003 to describe the first specimen to preserve this feature as a "four-winged dinosaur" and to speculate that it may have glided  using all four limbs for lift. Subsequent studies have suggested that Microraptor was capable of powered flight as well.

Microraptor was among the most abundant non-avialan  dinosaurs in its ecosystem, and the genus is represented by more fossils than any other dromaeosaurid, with possibly over 300 fossil specimens represented across various museum collections.[3]
