With wingspans up to 8 meters and necks as long as 1.5 meters, scientists have always wondered how their unusual bodies allowed them to hunt, walk, and fly. “With size comes all kinds of complicated biological problems,” says Nizar Ibrahim, an anatomist and paleontologist at the University of Portsmouth and a study co-author
