The '''Odontoanserae''' is a [[clade]] that includes [[Odontopterygiformes]] (pseudo-toothed birds) and [[Anseriformes]] (waterfowls). It is the sister [[taxon]] of [[Neoaves]]. The Odontoanserae are most probably the first major group of modern birds that has developed adaptations to aquatic life. Webbed feet and functional salt glands, for instance, are most likely derived characters of this clade, although the degree of development of these structures are known to vary among waterfowls. Similar adaptations have appeared later in the evolution of modern birds, in various neoavian groups.<ref>Bourdon, Estelle (2005) Osteological evidence for sister group relationship between pseudo-toothed birds (Aves: Odontopterygiformes) and waterfowls (Anseriformes), Naturwissenschaften, 92, 586-591</ref> |

The Odontoanserae is a purposed clade that includes the family Pelagornithidae (pseudo-toothed birds) and Anseriformes (waterfowls).[1] The placement of the pseudo-toothed birds in the evolutionary tree of birds has been problematic, with. In 2005 a cladistic analysis had found support in placing pseudo-toothed birds as the sister group to waterfowl.[1] Evidence for this comes from. Furthermore a 2013 study on the growth pattern and structure of the pseudoteeth in Pelagornis mauretanicus shows more support of Odontoanserae as both groups have "soft rhamphotheca, or delayed hardening of the rhamphotheca."[2]
