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.[3] 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.[4] Because of these similarities it is phylogenetically placed between cassowaries and emus.[5]
