Largest and Fastest Moving Dinosaurs

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.
