The quokka (/ ˈ k w ɒ k ə /) (Setonix brachyurus) [4] is a small macropod about the size of a domestic cat. It is the only member of the genus Setonix. Like other marsupials in the macropod family (such as kangaroos and wallabies), the quokka is herbivorous and mainly nocturnal. [5] The quokka's range is a small area of southwestern Australia.
Macropodidae (lit. 'long foot') is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, quokkas, and several other groups.These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent (the mainland and Tasmania), New Guinea and nearby islands.
It was thought to be extinct for much of the 20th century, having not been spotted for around a century, until its rediscovery in 1994. The only naturally located population is found in Two Peoples Bay Nature Reserve in Western Australia, where they co-exist with quokkas (Setonix brachyurus), but in 2015 a bushfire destroyed 90% of their habitat.

The northern quoll is still found in the region. [8] The fossil species D. dunmalli , described by Bartholomai in 1971, is the oldest species recovered to date. Its remains were found in Pliocene deposits near Chinchilla in southeastern Queensland.
The only quagga to have been photographed alive was a mare at the Zoological Society of London's Zoo. Five photographs of this specimen are known, taken between 1863 and 1870. [23] On the basis of photographs and written descriptions, many observers suggest that the stripes on the quagga were light on a dark background, unlike other zebras.
The Spanish Flu, the second deadliest pandemic in history after the bubonic plague, along with the aftermath of World War I and ensuing political and social chaos, made 1918 a tough time to be alive.
Robust population data exist only for the last two or three centuries. Until the late 18th century, few governments had ever performed an accurate census. In many early attempts, such as in Ancient Egypt and the Persian Empire, the focus was on counting merely a subset of the population for purposes of taxation or military service. [2]
