Pelagornithidae
Les (appelés aussi « oiseaux à pseudo-dents » et « oiseaux à dents osseuses ») forment une famille préhistorique de grands oiseaux de mer. Leurs restes fossiles ont été retrouvés dans le monde entier, au sein de roches datant de la fin du Paléocène jusqu'à la limite entre le Pliocène et le Pléistocène. Le trait le plus remarquable de ces oiseaux est la présence de pointes semblables à des dents sur les bords de leur bec.
Pelagornis
Pelagornis (littéralement « oiseau de haute mer ») est un genre fossile d'oiseaux de très grande envergure (), ayant vécu du Miocène au Pléistocène et notamment au Gélasien. Pelagornis a été décrit en 1857 par le paléontologue et préhistorien gersois Édouard Lartet à partir d'un humérus trouvé en Gascogne. Pelagornis est construit sur les mots grecs (« haute mer ») et (« oiseau »). vignette|upright=2|Moulage d'un squelette de Pelagornis miocaenus au Musée national d'histoire naturelle des États-Unis de Washington.
Cyphornis
Cyphornis is a genus of the prehistoric pseudotooth birds. These were probably rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty. Only a single species, Cyphornis magnus, is known to date. It is only known with certainty from a single specimen, the rather abraded proximal part of a left tarsometatarsus which was found at Carmanah Point on Vancouver Island (Canada), where the Juan de Fuca Strait opens into the Pacific.
Dasornis
Dasornis is a genus of the prehistoric pseudotooth birds. These were probably rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty. Almost all known material of this bird is from some 50 million years ago (Ma) and has been recovered from the Ypresian (Early Eocene) London Clay of the Isle of Sheppey (England).
Palaeochenoides
Palaeochenoides is a genus of the prehistoric pseudotooth birds of somewhat doubtful validity. These were probably rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty. Only a single species, Palaeochenoides mioceanus, is known to date. The first fossil assigned to it – a distal right femur piece – was found near the source of the Stono River in Charleston County, South Carolina (United States).
Pseudodontornis
Pseudodontornis is a rather disputed genus of the prehistoric pseudotooth birds. The pseudotooth birds or pelagornithids were probably rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty. Up to five species are commonly recognized in this genus. But actually the genus Pseudodontornis is barely more than a nomen nudum.
Tympanonesiotes
Tympanonesiotes is a somewhat doubtfully valid genus of the prehistoric pseudotooth birds. These were probably rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty. Only a single species, Tympanonesiotes wetmorei, is known to date. The only known specimen (USNM 16809), a distal right tarsometatarsus end, was found in the Cooper River near Drum Island (Charleston) at Charleston, South Carolina (United States).
