 "Pelagornis" meanwhile, described from wing bones, was traditionally placed in a monotypic "pelecaniform" family Pelagornithidae.This was often assigned either to the gannet and cormorant suborder Sulae (which was formerly treated as superfamily Sulides in suborder Pelecanae), or to the Odontopterygia.The sternum of "Gigantornis" was placed in the albatross family (Diomedeidae) in the order of tube-nosed seabirds (Procellariiformes).
