The Broad-faced Potoroo (Potorous platyops), is an extinct mammal that was (according to sub-fossil remains) believed to be widely distributed from the semi-arid coastal districts of South Australia to the Western Australia coast, and possibly as far north as North West Cape. It was recorded as a rare species in 1844 and the last known specimen was collected in 1875.
The habits of the Broad-faced Potoroo are unknown as it significantly declined in population before the settlement of Australia. It is clear that it avoided forested areas that its relatives (Long-nosed and Long-footed Potoroos) inhabit. Preserved specimens indicate that it was smaller than other Potoroos. The coat was grizzled grey above and dirty white below, the body similar in shape to that of a large rat. The ears were small and rounded, the muzzle fairly short, and the cheeks notably puffy.
