Pangalliformes

Pangalliformes is the scientific name of a provisional clade of birds within the group Galloanserae. It is defined as all birds more closely related to chickens than to ducks, and includes all modern chickens, turkeys, pheasants, and megapodes, as well as extinct species that do not fall within the crown group Galliformes.

==Classification== Galliform-like pangalliformes are represented by extinct families from the Paleogene, namely the Gallinuloididae, Paraortygidae and Quercymegapodiidae. In the early Cenozoic, some additional birds may or may not be early Galliformes, though even if they are, it is rather unlikely that these belong to extant families: †Argillipes (London Clay Early Eocene of England) †Coturnipes (Early Eocene of England, and Virginia, USA?) †Paleophasianus (Willwood Early Eocene of Bighorn County, USA) †Percolinus (London Clay Early Eocenee of England) †"Palaeorallus" alienus (middle Oligocene of Tatal-Gol, Mongolia) †Anisolornis (Santa Cruz Middle Miocene of Karaihen, Argentina)
