Bettongia pusilla McNamarra

Nullabor Dwarf Bettong (Bettongia pusilla)

The Nullabor Dwarf Bettong was described in 1997 based on subfossil skeletal remains that were found in caves on the Nullabor Plain, an large arid desert region in southern Australia.

The species apparently disappeared shortly after the arrival of European settlers in the region, who brought with them cats and foxes which preyed upon the native mammals and still do so up to this day.

The native people of the Pilbara region allegedly have two names for a very small kangaroo species, weelba respectively wirlpa, which may have originally been used for this species. [1]

Perameles eremiana Spencer

Desert Bandicoot (Perameles eremiana)

The Desert Bandicoot, described in 1897, was restricted to the arid center of Australia; the natives there called it iwurra, mulgaruquirra and waliya.

The nocturnal and flesh-eating species inhabited dry, sandy areas covered with spinifex grass (Spinifex spp.) and other tusock grasses.

The Desert Bandicoot disappeared most likely due to predation by feral cats and Red Foxes (Vulpes vulpes (L.)) introduced from Europe; the last sighting took place in 1943 in Western Australia.
