European researchers said in LONDON at July 1, Even though ostriches has their wings but they can't fly, how they use their wings when running offers clues to how two-legged dinosaurs may have moved,.
Britain's Society for Experimental Biology announced, Ostriches used their wings as sophisticated air rudders and braking aids.Likewise, techniques may have been used by their bi-pedal, or two-legged, dinosaur ancestors.
Some of the largest and fastest-moving dinosaurs, such as the 25-foot-long Gigantoraptor, may have used feathered forelimbs for increased stability and maneuverability when moving at speed, a study suggests.
