Reanalysis of fossil remains suggests that the earliest flying dinosaurs used two sets of wings like a biplane.

The research, published by Sankar Chatterjee of Texas Tech University and R. Jack Templin in this week’s online issue of Proceedings of the National Academy of Sciences, argues that Microraptor gui, one of the earliest known gliders dating to 125 million years ago, utilized four wings to glide between treetops.

“Like the Wright 1903 Flyer, Microraptor, a gliding relative of early birds, took to the air with two sets of wings,” the authors write. “Aircraft designers have mimicked many of nature’s flight ‘inventions,’ usually inadvertently. Leading edge slats delay
stalling, as does the alula of birds; birds’ feet act as airbrakes, and streamlining reduces drag. Now, it seems likely that Microraptor invented the biplane 125 million years before the Wright 1903 Flyer.”
