Oligocene birds of Australia

Emuarius is an extinct genus of casuariiform flightless bird from Australia that lived during the early Miocene and late Oligocene. It is one of two known genera of emu. There are two known species in the genus, Emuarius gidju and Emuarius guljaruba. The birds in this genus are known as emuwaries. This name comes from a combination of emu and cassowary. This is due to its cassowary-like skull and femur and emu-like lower leg and foot. Because of these similarities it is phylogenetically placed between cassowaries and emus.

Australotadorna alecwilsoni is an extinct genus and species of bird, in the shelduck subfamily of the duck family, from the Late Oligocene of central Australia. The genus name comes from the Latin australis ("southern" or, derivatively, "Australian") and Tadorna (a genus of shelducks). The specific epithet honours Alec Wilson, pastoral lease holder of Frome Downs Station, who supported palaeontological access to, and investigation of, fossil sites on his property. The type locality is Lake Pinpa in the Lake Eyre Basin of north-eastern South Australia.
