Madakoala
''Madakoala'' is a genus of extinct phascolarctid marsupials with three known species, ''Madakoala devisi,'' ''Madakoala wellsi'' ''and'' ''Madakoala robustus''. It is allied to extinct genera ''Invictokoala, Koobor, Litokoala, Nimiokoala, Perikoala, Phascolarctos'' and ''Priscakoala'', along with ''Phascolarctos'', the genus of the existing koala. ''Madakoala'' went extinct around 280,000 years ago in the Pleistocene epoch. They are known to exist by limited cranial material in fossils, so the existence of some of the subspecies is questionable because of missing dental data.

Phascolarctid
The Phascolarctidae (''φάσκωλος (phaskolos)'' - pouch or bag, ''ἄρκτος (arktos)'' - bear, from the Greek ''phascolos'' + ''arctos'' meaning pouched bear) is a family (biology), family of Marsupialia, marsupials of the order Diprotodontia, consisting of only one extant species, the koala, and six well-known fossil species, with another five less well known fossil species, and two fossil species of the genus ''Koobor'', whose taxonomy is debatable but are placed in this group. The closest relatives of the Phascolarctidae are the wombats, which comprise the family Vombatidae. The fossil record of the family dates back to the Middle Miocene or Late Oligocene.

Perikoala
''Perikoala'' is an extinct genus of marsupials, related to the modern koala. The genus diverged from a common ancestor of the other koala genera ''Nimiokoala'', ''Litokoala'', and ''Phascolarctos'', which contains the living koala.

Phascolarctos
''Phascolarctos'' is a genus of marsupials with one living species, the koala ''Phascolarctos cinereus'', an iconic animal of Australia. Several extinct species of the genus are known from fossil material, these were also large tree dwellers that browsed on ''Eucalyptus'' leaves. Taxonomy The genus was named by French zoologist Henri Marie Ducrotay de Blainville in 1816. The type species, the modern koala, was named as '' Lipurus cinereus'' by G. A. Goldfuss in 1817, later combined as ''Phascolarctos cinereus''. Goldfuss published this name with a reproduction of John Lewin's 1803 illustration of the species in New South Wales. An accepted synonomy of other generic names referring to ''Phascolarctos'' was published in 1988. The koala is listed in national conservation legislation as "''Phascolarctos cinereus'' (combined populations of Qld, NSW and the ACT)", previously determined in 2012 to be "a species for the purposes of the EPBC act 1999" (EPBC). The koala was classified as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsupial
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, bandicoots, and the extinct thylacine. Marsupials represent the clade originating from the last common ancestor of extant metatherians, the group containing all mammals more closely related to marsupials than to placentals. They give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time. Close to 70% of the 334 extant species occur on the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 30% are found in the Americas—primarily in South America, thirteen in Central America, and one species, the Virginia opossum, in North America, n ...

Invictokoala
''Invictokoala monticola'' is an extinct phascolarctid marsupial mammal from the middle Pleistocene of central-eastern Queensland, Australia. The holotype was found during cave excavations at Mount Etna (a local mountain in central-eastern Queensland which was named after the famed Sicilian volcano). It was first named by Gilbert J.

Litokoala
''Litokoala'' is an extinct genus of marsupials, and along with '' Nimiokoala'', is closely related to the modern koala. The three genera may have diverged at an earlier date, although the drying of the continent and the expansion of ''Eucalyptus'' forests towards the late Miocene may have delayed the evolution of cranial features unique to the modern genera. This indicates that either fossil genus could be an ancestor of the modern genus, or the modern genus has a common ancestor to both. More material needs collection to improve their taxonomical relationships. The genus lived about 10–16 million years ago in the middle Miocene Riversleigh of Queensland. This area is described as a rainforest habitat at time of sediment deposition. It had a different diet to the modern species, with the dental symphysis unfused, indicating a diet that was properly varied in nature, unlike the specialised nature of ''Phascolarctos''. The size is estimated to be only half of the modern ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priscakoala
''Priscakoala'' is an extinct genus of koala from the Early Miocene of Riversleigh, Australia. As cited in It has one species: ''Priscakoala lucyturnbullae''. The prefix "''prisca''" comes from the Latin meaning old, ancient, primeval or primitive. It was used to indicate that this genus is one of the oldest and simplest form of the koala. The species ''P. lucyturnbullae'' was named for Lucy Turnbull a businesswoman, wife of former Prime Minister Malcolm Turnbull Malcolm Bligh Turnbull (born 24 October 1954) is an Australian former politician and businessman who served as the 29th prime minister of Australia from 2015 to 2018.

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...
