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.
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).
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).
Pelagornithidae
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. Most of the common names refer to these birds' most notable trait: tooth-like points on their beak's edges, which, unlike true teeth, contained Volkmann's canals and were outgrowths of the premaxillary and mandibular bones.
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.
Osteodontornis
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. O. orri was named after the naturalist Ellison Orr (1857-1951). The bony-toothed or pseudotooth birds were initially believed to be related to albatrosses in the Procellariiformes, but actually they seem to be rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty.
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).
