Paleogene birds

Presbyornis is an extinct genus of presbyornithid bird from North America during the Paleogene period, between the Late Paleocene and Early Eocene.

Anatalavis is genus of prehistoric birds related to ducks and geese, perhaps to the magpie-goose (Anseranas semipalmata) in particular. Alternatively, it might have been a more basal lineage of Anserimorphae distinct from the living waterfowl, similar or even related to the roughly contemporary Conflicto antarcticus from the Danian of Antarctica.

Odontopteryx is a genus of the extinct pseudotooth birds or pelagornithids. 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.
