The koala is a robust animal with a large head and vestigial or non-existent tail. [11]: 1 [31] It has a body length of 60–85 cm (24–33 in) and a weight of 4–15 kg (8.8–33.1 lb), [31] making it among the largest arboreal marsupials. [32] Koalas from Victoria are twice as heavy as those from Queensland.
The giant koala (Phascolarctos stirtoni) is an extinct arboreal marsupial which existed in Australia during the Pleistocene epoch. Phascolarctos stirtoni was about one-third larger than the contemporary koala , P. cinereus , [ 2 ] and has an estimated weight of 13 kg (29 lb), which is the same weight as a large contemporary male koala.
The extinct species are presumed to have similar diet and habits to the modern koala, the largest Australian folivore, which was exceeded in size by the even more robust P. stirtoni. [11] The tail of koalas is almost absent, an unusual characteristic for a tree climbing mammal, although other anatomical features are well suited to that habitat.
Brain size usually increases with body size in animals (i.e. large animals usually have larger brains than smaller animals); [4] the relationship is not, however, linear. Small mammals such as mice may have a brain/body ratio similar to humans, while elephants have a comparatively lower brain/body ratio. [4] [5]

A typical precocial mammal has a gestation period almost four times longer than a typical altricial mammal of the same body size. [20] Precocial mammal species generally have greater adult body weights than altricial mammals as precocial mammals have markedly longer gestation periods than altricial mammals. [21]

In the absence of postcranial fossils, the size of Nimiokoala has been estimated from measurements of its surviving teeth. It is estimated to have body length of about 25–30 cm (9.8-11.8 in), and a weight of about 3.5 kg (7.7 lb), one third the size of modern koalas and more than 10 times smaller than the largest known representative of Phascolarctidae (Phascolarctos yorkensis).
