  • Anseriformes ( Anseriformes )
  • Gallinaceous birds ( Galliformes )

The Galloanserae (Latin Gallus = "rooster" and Anser = " Goose" ) are in addition to the Neoaves one of two major clades of Neukiefervögel and include the eponymous orders of Galliformes ( Galliformes ) and Anseriformes ( Anseriformes ) and extinct groups that are closer to them are used as the Neoaves, including possibly an Pelagornithidae and Gastornithidae.

Common derived osteological features of the Galliformes and Anseriformes are in the skull in front: The Basipterygoid - extensions are egg-shaped and fixed, the quadrate has only two Mandibulargelenkknorren on and the lower jaw is long blade-shaped Retroartikularfortsätze. Furthermore, almost all analyzes demonstrate molecular data (eg, mitochondrial DNA; nuclear DNA, DNA -DNA hybridization ) the close relationship between the two groups.

The first evidence for galloanserine Birds are probably represents skeletal remains of the late Cretaceous period, which were described as Palintropus, Vegavis and Austinornis.
