Desert Rat-kangaroo

Caloprymnus campestris

Extinct

No living individual remains anywhere in the world.

Spotted something wrong?

The desert rat-kangaroo was a small marsupial of the deserts of central Australia, the only representative of its genus. It is one of the least known mammals in the world: it was described in 1841 from a handful of specimens and then vanished for ninety years, until in 1931 the naturalist Hedley Finlayson found it again in north-eastern South Australia. The last reliable sightings are from 1935. It lived in a shallow nest made of grass, without digging burrows, on bare, scorched plains.

Fun facts

  • fisiologíaIt can live its whole life without drinking, getting all the moisture it needs from metabolising the dry seeds it eats.
  • In 1931 Finlayson described how one individual ran for kilometres without any sign of tiring, leaving a horse at full gallop behind.
  • It is known only from a handful of specimens and from a few months of observations spread over almost a century: it disappeared before anyone could study it.
