The bird family Casuariidae has four surviving members: the three species of cassowary and the emu.
All living members of the family are very large flightless birds native to Australia-New Guinea.

Systematics and evolution
The fossil record of casuariforms is interesting, but not very extensive.
Some Australian fossils initially believed to be from emus were recognized to represent a distinct genus, Emuarius, which had a cassowary-like skull and femur and an emu-like lower leg and foot.
