A somewhat generic reconstruction of Osteodontornis, but unlikely to be very wrong in any major aspect regardless of these birds' actual relationships

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 Late Paleocene and the Pliocene-Pleistocene boundary.

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 then-recently deceased naturalist Ellison Orr.
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. Also, their internal taxonomy is not well-resolved. An earlier-described pseudotooth bird, Cyphornis magnus from Vancouver Island (Canada), was believed to be of Eocene age but is nowadays assumed to have lived in the Early Miocene, not too long before the Clarendonian (Middle/Late Miocene) O. orri. It may be that Osteodontornis is a junior synonym of Cyphornis. |
