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 The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.

Phascolarctid
The Phascolarctidae (''φάσκωλος (phaskolos)'' - pouch or bag, ''ἄρκτος (arktos)'' - bear, from the Greek ''phascolos'' + ''arctos'' meaning pouched bear) is a family of marsupials of the order Diprotodontia, consisting of only one extant species, the koala, and six well-known fossil species, with another six 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.

Phascolarctos
''Phascolarctos'' is a genus of marsupials with one extant 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 synonymy 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).

Koalas
The koala (''Phascolarctos cinereus''), sometimes inaccurately called the koala bear, is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family '' Phascolarctidae''. Its closest living relatives are the wombats. The koala is found in coastal areas of the island's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, dark nose. The koala has a body length of and weighs . Its fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations are possibly separate subspecies, but not all researchers accept this. Koalas typically inhabit open ''Eucalyptus'' woodland, as the leaves of these trees make up most of their diet. This eucalypt diet has low nut ...

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Marsupial
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including Kangaroo, kangaroos, Koala, koalas, Opossum, opossums, Phalangeriformes, possums, Tasmanian devil, Tasmanian devils, Wombat, wombats, Wallaby, wallabies, and Bandicoot, bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to Placentalia, placentals. The evolutionary split between placentals and marsupials occurred 125-160 million years ago, in the Middle Jurassic-Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Price and Scott A. Hocknull in 2011 The year marked the start of a Arab Spring, series of protests and revolutions throughout the Arab world advocating for democracy, reform, and economic recovery, later leading to the depositions of world leaders in Tunisia, Egypt, and Yemen ....

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 around 16–10 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] |
Nimiokoala
''Nimiokoala greystanesi'' is an extinct marsupial, closely related to the extant koala, that inhabited northwestern Queensland in the early-middle Miocene (23–16 million years ago). It is the only species assigned to the genus ''Nimiokoala''. Along with species of sister genus '' Litokoala'', it is the smallest representative of family Phascolarctidae. Based on cladistic analysis, ''Nimiokoala'' is one of the more basal genera of Phascolarctide. It died out due to climate change rendering the environment more arid. It probably had a more generalized diet than that of the modern species, but its exact food preferences are unknown. Etymology The generic name, ''Nimiokoala,'' is derived from the Latin word ''Nimio'' "excessive" referring to its complex molar morphology relative to other koala species. The specific name, ''greystanesi,'' honors Greystanes High School. History of research As of 2013, the fossil record of extinct koalas consists of 163 specimens across 5 ...

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. He held office as Liberal Party of Australia, leader of the Liberal Party an ..., and supporter of the research that discovered the genus.
