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. Two species are recognised * ''Perikoala palankarinnica'' Ruben A.

Koala
The koala or, inaccurately, koala bear (''Phascolarctos cinereus''), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats. The koala is found in coastal areas of the mainland'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, spoon-shaped nose. The koala has a body length of and weighs . 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 possibly are separate subspecies, but this is disputed. Koalas typically inhabit open ''Eucalyptus'' woodland, as the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and calor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Chattian
The Chattian is, in the geologic timescale, the younger of two ages or upper of two stages of the Oligocene Epoch/Series. It spans the time between . The Chattian is preceded by the Rupelian and is followed by the Aquitanian (the lowest stage of the Miocene). Stratigraphic definition The Chattian was introduced by Austrian palaeontologist Theodor Fuchs in 1894. Fuchs named the stage after the Chatti, a Germanic tribe.Berry, Edward W"The Mayence Basin, a Chapter of Geologic History" ''The Scientific Monthly'', Vol. 16, No. 2, February 1923. pp. 114. Retrieved March 18, 2020. The original type locality was near the German city of Kassel. The base of the Chattian is at the extinction of the foram genus ''Chiloguembelina'' (which is also the base of foram biozone P21b). An official GSSP for the Chattian Stage was ratified in October of 2016. The top of the Chattian Stage (which is the base of the Aquitanian Stage, Miocene Series and Neogene System) is at the first appearance o ...

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] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
