LOS ANGELES, Oct. 6 (UPI) -- The earliest bird species lived alongside the dinosaurs, but scientists continue to disagree on exactly how much flying these ancient birds were doing. New research may offer some clarity on the subject.
Analysis of an exceptionally well-preserved bird wing fossil suggests at least some ancient bird species were capable of the kinds of aerial maneuvers modern flyers perform. In other words, prehistoric birds could ascend to considerable heights, and once there, could swoop, dive, pitch and roll.
