Orders

The Galloanserae ( Lat. Gallus = "cock" and Anser = "goose") are next to the Neoaves one of two large groups of the new jaw birds and contain the eponymous orders of the hen birds (Galliformes) and geese birds (Anseriformes) as well as extinct groups that are closer to them are related than to the Neoaves, including possibly the Pelagornithidae and the Gastornithidae . The young of the Galloanserae are fleeing nests.

Common derived osteological features of the fowl and geese are found in the skull: the basipterygoid processes are egg-shaped and firmly attached, the quadratum has only two mandibular joint cartilages and the lower jaw shows long, blade-shaped retro-articular processes. Furthermore, almost all analyzes of molecular data (e.g. mitochondrial DNA; DNA of the cell nucleus; DNA-DNA hybridization) confirm the close relationship between the two groups.

The first evidence for galloanserine birds is likely to be found in skeletal remains from the late Cretaceous period, which were described as Palintropus , Vegavis and Austinornis .

In March 2020, Belgian scientists described a dove-sized 66.7 million year old fossil bird ( Asteriornis maastrichtensis ) that shows features of geese and chickens.

Systematics

According to the review by Mayr (2009), the Galloanserae show the following relationships (supplemented by Ichthyornis and the Carinatae according to Benton, 2005):

 Carinatae  

 Ichthyornis


  Neornithes  

 Great jawbirds


  New pine birds  

 Neoaves


  Galloanserae  

 Chicken birds


   

 ? Pelagornithidae


  Anserimorphae  

 ? Gastornithidae


   

 ? Dromornithidae


   

 Goose birds
