The oolacunta, or desert rat-kangaroo (Caloprymnus campestris), is a small marsupial first described in 1843 from an unknown location in South Australia. It was not seen again until 1931, when several specimens were collected over the next few years in the far north-east of South Australia. A few reports of the species were collected from the 1970s and 1980s, but field researchers were unable to find a trace of the species during the 1990s and 2000s, and it was believed to have gone extinct. Robinson and For- rest (2011) detailed a possible sighting of this marsupial in the Peake Hill Mine area by a member of a nature group party camping by the river.
