Broad-faced potoroo
The broad-faced potoroo (Potorous platyops) is an extinct potoroid marsupial that was found in southwestern Australia. The first specimen was collected in 1839, and described by John Gould in 1844. Only a small number of specimens have been collected since. The last live capture was in 1875. Subfossil remains indicate that it had an extensive distribution around the semiarid coastal districts of Southwest Australia.
The habitat of the broad-faced potoroo is almost entirely unknown, but unlike its relatives, such as the long-nosed potoroo Potorous tridactylus and long-footed Potorous longipes, they do not seem to have lived in dense understories in forests. Preserved specimens indicate that it was smaller than other potoroos at around 300 mm (1 ft) long with a 180-mm tail. Their weight is estimated at 800 g. Their coat was grizzled with yellowish hairs above and greyish white below. Their body was similar in shape to that of other potoroids. Their ears were small and rounded, muzzle fairly short, and cheeks notably puffy.
The first description was published by John Gould, using a specimen obtained by his collector John Gilbert at "Walyema Swamps near Northam, Western Australia". Gilbert visited this inland region while collecting around the recently established Swan River Colony. The site he referred to was determined to be Lake Walyormouring.
The single specimen forwarded to Gould was presented to the Linnean Society of London, and the partial skull and skin of a female was deposited in the British Museum of Natural History. There were few collected after Gould's initial description. There was one animal collected by James Drummond and recorded in a letter in the 1840s, the collector George Masters prepared four specimens in the 1860s, presumably when he made a large collection of taxa at Mordup. The last collection of living Potorous platyops was in 1874, collected by William Webb and are now held at the Macleay Museum in Sydney.
Curator and collector Hedley H. Finlayson described the remains of a potoroine animal found in a South Australian cave, which were similar to the Potorous platyops. However, the bones were retrieved from a site far from where the Potorous platyops was thought to be found, as well as the teeth being different from previously collections specimens. He ended up naming it as a new species, Potorous morgani. The specimen was later identified as a Potorous platyops. The skull that was studied and was held at a South Australian museum, amongst a deposit of multiple taxa from Kelly's Hill Caves, which was collected by A.M. Morgan. The specific epithet morgani refers to the collector. Finlayson's 1934 description recognised a close similarity to this species. When he obtained more specimens, which were collected at the same cave system on Kangaroo Island by Edith May, he obtained a second partial skull. Comparison of the dentition and other morphological characteristics was limited to works published by G. R. Waterhouse (1846), Oldfield Thomas (1888) and B. Arthur Bensley (1903) whose descriptions of P. platyops are recorded at the BMNH.
Common names include broad-faced potoroo and a name from the Nyungar language, moda, which was recorded by Gilbert and noted in Gould's 1844 description as mor-da, and mort or moort by other ecologists writing shortly after its extinction. The name was obtained through an interview with Nyungar peoples at King George Sound by Gilbert. Early records show that it was also named the broad-faced rat kangaroo.
The broad-faced potoroo is a member of the genus Potorous. It is described as having a relatively broad skull and shorter muzzle. The species is presumed to have become extinct sometime after the last recorded capture of the animal in 1875, and sometime before 1905.
The colour of the pelage is greyish brown at the upper-side. Straw-yellow hairs are interspersed through the fur to give a streaked effect. The underside and the flanks are pale grey. The head and body are about 305 millimetres in length, while the tail is about 178 mm long.[clarification needed] Their hind feet are about 54 mm in length and their weight is approximately 800 grams. Their noses are short and blunt, which is an unusual characteristic among potorines and is usually associated with species such as the rufous bettong (Aepyprymnus rufescens) and the desert rat-kangaroo (Caloprymnus campestris).
