The Casuariiformes /kæsjuːˈæri.ɪfɔːrmiːz/ is an order of large flightless birds that has four surviving members: the three species of cassowary, and the only remaining species of emu. They are divided into either a single family, Casuariidae, or more typically two, with the emu splitting off into its own family, Dromaiidae.
All four living members are native to Australia-New Guinea,[3] but some possible extinct taxa occurred in other landmasses.
