It’s a dinosaur, it’s a biplane ...
From Times Wire Reports
A new study of one of the earliest feathered dinosaurs suggests it may have had upper and lower sets of wings, much like a biplane.
The dinosaur, known as Microraptor gui, was originally described in 2003 by Chinese researchers as having aerodynamic feathers on both its arms and legs, arranged in flight one behind the other, like a dragonfly. Sankar Chatterjee of Texas Tech University proposed in this week’s online issue of the Proceedings of the National Academy of Sciences that further analysis suggested the legs could have been held below the body in flight, creating two staggered wing sections.
