The broad-faced potoroo is also an extinct species of marsupial and this species lived in Australia. Preserved specimens indicate that it was smaller than the other potoroos at around 24 cm long with an 18-cm tail. The coat was grizzled grey above and dirty white below, the body similar in shape to that of a large rat. The habits of the broad-faced potoroo are almost entirely unknown. The first specimen was collected in 1839 and described by John Gould in 1844, but even then it was rare.
