Its wings were even more proportionally long and narrow than those of the largest flying birds alive today, the albatrosses. Flight performance of the largest volant bird. It measures 160 to 183 cm (5 feet 3 inches to 6 feet 0 inches) in length, 7.25-15 kg (16.0-33.1 lb) in weight, and 290-345 cm (9 ft 6 in–11 ft 4 in) in wingspan. In having good cranial and limb material, the Oligocene taxon Pelagornis sandersi is among the better known species.Note the difference in size … Modeling the flight patterns of the largest flying bird ever to have lived, Pelagornis sandersi. They just appear, in the Paleocene, out of nowhere. The pseudoteeth are likely an adaptation to grab and hold onto large fish.

The type species Pelagornis miocaenus is known from Aquitanian (Early Miocene) sediments – formerly believed to be of Middle Miocene age – of Armagnac (France).
