Diprotodontia

Diprotodontia is an order of marsupial mammals including kangaroos, koalas, wombats, possums, and gliders. Its members are distinguished by large, forward-pointing lower incisors.

Marsupial: A mammal whose young are born at an early stage of development and typically complete development attached to a teat. Diprotodontians belong to this mammal group, though some have reduced or absent pouches.
Kangaroo: A large macropod marsupial adapted for powerful hopping and grazing or browsing. Kangaroos are among the most recognizable members of Diprotodontia.
Macropodiformes: A diprotodontian suborder containing kangaroos, wallabies, and their close relatives. Its members form the hopping branch most associated with the order.
Australian megafauna: Large-bodied animals that lived in Australia during the Pleistocene and became extinct before or around the end of that epoch. Several extinct diprotodontians were prominent members of this fauna.
Dasyuromorphia: An order of marsupials that includes quolls, Tasmanian devils, and most other carnivorous marsupials. Its members contrast with the predominantly herbivorous diprotodontians in diet and dental form.
Diprotodonty: A dental condition characterized by a pair of prominent, forward-pointing lower incisors. This defining feature gives Diprotodontia its name and distinguishes its members from other marsupials.
Koala: An arboreal marsupial that feeds mainly on eucalyptus leaves in eastern Australia. The koala is a specialized diprotodontian whose diet and tree-dwelling life contrast with kangaroos.
Vombatiformes: A diprotodontian suborder containing wombats, koalas, and extinct relatives. This branch groups two living forms with very different diets and lifestyles.
Pleistocene Australia: The Australian continent during the Pleistocene, when its environments supported distinctive megafauna and human populations. Fossils from this period document the recent history of giant diprotodontians.
Peramelemorphia: An order of marsupials containing bandicoots and bilbies. Bandicoots have a different dental pattern and are classified outside Diprotodontia.
