'Four-winged' Dinosaurs

摘要

In succession to their discovery of Microraptor zhaoianus in 2000, Xu Xing and Zhou Zhonghe, both paleontologists at the CAS Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), together with their colleagues reported in Nature (Januanry 20, 2003) a new species of Microraptor with "four wings", that is, its legs have feathers well asymmetrically arrayed, like its other wings. This suggests the creature might be able to glide.
