The heaviest known flying bird ever lived, Argentavis magnificens (“magnificent Argentine bird”, or more literally “magnificent silver bird”), was more than twice Pelagornis’ weight but had a shorter wingspan. It had an estimated wingspan of 5.09-6.07 m (16.7-19.9 ft), a height of circa 1.5-2 m (4.9-6.6 ft), and a mass of approximately 70-72 kg (154-159 lb).
