A small international team of biologists, geologists and paleontologists has found evidence that a bird-sized dinosaur from the early Cretaceous used its wings to run faster. In their study published in the Proceedings of the National Academy of Sciences, the group analyzed both the footprints and the creature that left them and reported evidence for wing-assisted running.
