Taxonomy

The description of the population was revised in 2019, separating a central western population as Chaeropus yirratji and recognised two earlier descriptions as subspecies Chaeropus ecaudatus ecaudatus (found in southeastern Australia) and Chaeropus ecaudatus occidentalis (found in western and southwestern Australia).[2]

Description

It has been believed to be extinct since the mid-20th century, having reportedly vanished from its final refuge in southern Australia by 1945.[3] It was presumably the first of the two species of Chaeropus to go extinct.

It is thought to have been distributed in shrubland habitats in the southern regions of Australia's deserts, and its range likely extended to Western Australia. It physically closely resembled the northern pig-footed bandicoot (C. yirratji), but it had fewer holes on its palate and shorter feet. It also had a different dentition than C. yirratji, indicating that it may have had a different diet. The two species were formerly considered conspecific until a study released in 2019 found them to be separate species.[4][5] This species likely went extinct due to predation by introduced red foxes and feral cats, as well as habitat degradation by introduced livestock.[6]

gollark: So you admit it *could* be used for bad things?
