Could Dinosaurs Fly?

Some dinosaurs may not have been restricted to life on the ground and instead could have launched into the air for quick flights, researchers have found. "They probably could not sustain flight for long or go very far," said study lead researcher Michael Habib, an assistant professor of cell and neurobiology at the University of Southern California. Birds are the descendants of theropods — dinosaurs that walked on two legs and mostly ate meat, including Velociraptor and Tyrannosaurus rex.
