The Pelagornithidae, commonly called pelagornithids, pseudodontorns, bony-toothed birds, false-toothed birds or pseudotooth birds, are a prehistoric family of large seabirds. Their fossil remains have been found all over the world in rocks dating between the Early Paleocene and the Pliocene - Pleistocene boundary.
Pelagornis, the type genus of the family Pelagornithidae, was long unrecognized as a pseudotooth bird as it was known mainly from arm bones. Thus, though the Pelagornithidae were long recognized as very distinct, they were allied with the cormorant and gannet in suborder Sulae (or superfamily Sulides in suborder Pelecanae) before it was ...

Gigantornis eaglesomei is a very large prehistoric bird described from a fragmentary specimen from the Eocene of Nigeria.It was originally described as a representative of the albatross family, Diomedeidae, but was later referred to the pseudotooth or bony-toothed bird family, Pelagornithidae.
Pelagornis sandersi comparison with the Andean condor (Vultur gryphus) and the wandering albatross (Diomeda exulans). The sole specimen of P. sandersi has a wingspan estimated between approximately 6.06 and 7.38 m (19.9 and 24.2 ft), [9] giving it the largest wingspan of any flying bird yet discovered, twice that of the wandering albatross, which has the largest wingspan of any extant bird (up ...
With an estimated wingspan of about 1 meter (3.3 feet), Protodontopteryx was the size of an average gull—much smaller than all post-Paleocene pelagornithids. It had a much stouter humerus than a typical pelagornithid, indicating it was less specialized toward sustained soaring.
But if the evolutionary scenario outlined above is correct, the family name Pelagornithidae could be restricted to the giant lineage, and the Odontopterygidae reestablished as name for the smaller lineage. Macrodontopteryx was initially also included in the Odontopterygidae, but if not a distinct genus it is more likely a young individual of ...
Osteodontornis is an extinct seabird genus.It contains a single named species, Osteodontornis orri (Orr's bony-toothed bird, in literal translation of its scientific name), which was described quite exactly one century after the first species of the Pelagornithidae (Pelagornis miocaenus) was.
