Kangaroo (other)
Kangaroos are four marsupials from the family Macropodidae (macropods, meaning "large foot"). In common use the term is used to describe the largest species from this family, the red kangaroo, as well as the antilopine kangaroo, eastern grey kangaroo, and western grey kangaroo. Kangaroos are indigenous to Australia and New Guinea. The Australian government estimates that 42.8 million kangaroos lived within the commercial harvest areas of Australia in 2019, down from 53.2 million in 2013. As with the terms " wallaroo" and " wallaby", "kangaroo" refers to a paraphyletic grouping of species. All three terms refer to members of the same taxonomic family, Macropodidae, and are distinguished according to size. The largest species in the family are called "kangaroos" and the smallest are generally called "wallabies". The term "wallaroos" refers to species of an intermediate size. There are also the tree-kangaroos, another type of macropod, which inhabit the tropi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Paraphyly
In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and most of its descendants, excluding a few monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia ( reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor, including all extant reptiles as well as the extinct synapsids, ...

Postnatal
The postpartum (or postnatal) period begins after childbirth and is typically considered to end within 6 weeks as the mother's body, including hormone levels and uterus size, returns to a non-pregnant state. The terms puerperium, puerperal period, or immediate postpartum period are commonly used to refer to the first six weeks following childbirth. The World Health Organization (WHO) describes the postnatal period as the most critical and yet the most neglected phase in the lives of mothers and babies; most maternal and infant mortality, newborn deaths occur during this period. In scientific literature, the term is commonly abbreviated to P''x'', where ''x'' is a number; for example, "day P5" should be read as "the fifth day after birth". This is not to be confused with the medical nomenclature that uses G P to stand for number and outcomes of pregnancy (gravidity and parity). A female giving birth in a hospital may leave as soon as they are medically stable, which can be as ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joey (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, nor ...

Pouch (marsupial)
The pouch is a distinguishing feature of female marsupials, monotremes and possibly most extinct non-placental mammals including eutherians like ''Zalambdalestes'' (and rarely in the males as in the water opossumNogueira, José Carlos, et al.Morphology of the male genital system of Chironectes minimus and comparison to other didelphid marsupials. Journal of mammalogy 85.5 (2004): 834-841. and the extinct thylacine); the name marsupial is derived from the Latin ''marsupium'', meaning "pouch". Marsupials give birth to a live but relatively undeveloped fetus called a joey. When the joey is born it crawls from inside the mother to the pouch. The pouch is a fold of skin with a single opening that covers the teats. Inside the pouch, the blind offspring attaches itself to one of the mother’s teats and remains attached for as long as it takes to grow and develop to a juvenile stage. Variations Pouches are different amongst different marsupials, two kinds distinguishable (on the front ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hind Leg
A hindlimb or back limb is one of the paired articulated appendages (limbs) attached on the caudal ( posterior) end of a terrestrial tetrapod vertebrate's torso.http://www.merriam-webster.com/medical/hind%20limb, Merriam Webster Dictionary-Hindlimb With reference to quadrupeds, the term hindleg or back leg is often used instead. In bipedal animals with an upright posture (e.g. humans and some primates), the term lower limb is often used. Location It is located on the limb of an animal. Hindlimbs are present in a large number of quadrupeds. Though it is a posterior limb, it can cause lameness in some animals. The way of walking through hindlimbs are called bipedalism. Benefits of hindlimbs Hindlimbs are helpful in many ways, some examples are: Frogs Frogs can easily adapt at the surroundings using hindlimbs. The main reason is it can jump high to easily escape to its predator and also to catch prey. It can perform some tricks using the hindlimbs such as the somersault and h ...

Black Wallaroo
The black wallaroo (''Osphranter bernardus''), also known as Woodward's wallaroo, is a species of macropod restricted to a small, mountainous area in Arnhem Land, Northern Territory, Australia, between South Alligator River and Nabarlek. It classified as near threatened, mostly due to its limited distribution. A large proportion of the range is protected by Kakadu National Park. Taxonomy The description of the species was published by Walter Rothschild in 1904. The author initially assigned the species to a new genus as ''Dendrodorcopsis woodwardi'', but revision of new material forwarded to England by the collector John Tunney persuaded the mammalogist Oldfield Thomas that the characteristics of the taxon were assignable to ''Macropus''. The specific epithet ''woodwardi'' was preoccupied by another subspecies of the genus ('' Macropus robustus woodwardi''), prompting Rothschild to assign the new epithet ''bernardus''. In 2019, a reassessment of macropod taxonomy determined t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grizzled Tree-kangaroo
The grizzled tree-kangaroo (''Dendrolagus inustus'') is a furry, long-tailed, bear-like mammal native to tropical rainforests on the island of New Guinea (split between Indonesia and Papua New Guinea). Like most tree-kangaroos (genus ''Dendrolagus''), it lives in trees and eats leaves, fruit, and bark. It is a member of the macropod family Macropodidae with kangaroos, and carries its young in a pouch like other marsupials. The tree-kangaroo is uncommon and threatened by hunting and habitat loss. It is found in foothill forests of northern and western New Guinea and is indigenous to some of the offshore islands.Flannery, T. 1995. ''Mammals of New Guinea.'' Reed Books. Description The grizzled tree-kangaroo grows to a length of about with males being considerably larger than females. It resembles a terrestrial kangaroo and its weight varies between about . The head is small, with a flat muzzle, the arms are powerful for climbing, the hind legs are long and the feet are large for ...

Lumholtz's Tree-kangaroo
Lumholtz's tree-kangaroo (''Dendrolagus lumholtzi'') is a rare, long-tailed bear-like mammal found in rainforests in northeastern Australia. Like most tree-kangaroos (genus ''Dendrolagus''), it lives alone in trees and feeds on plant matter. It belongs to the macropod family (Macropodidae) with kangaroos, and carries its young in a pouch like other marsupials. It is threatened by climate change and diseases, and is found in the hilly, fertile Atherton Tableland in Queensland. Name The species name ''lumholtzi'' is after the Norwegian explorer Carl Sofus Lumholtz (1851–1922), who was the first European to record a specimen in 1883. The local indigenous Dyirbal and Yidiny language name may have been either "mabi" or "mapi". Description and habitat It is the smallest of all tree-kangaroos, with males weighing an average of 7.2 kg (16 lbs) and females 5.9 kg (13 lbs). Its head and body length ranges from 480–650 mm, and its tail, 600–740 mm. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wallaby
A wallaby () is a small or middle-sized Macropodidae, macropod native to Australia and New Guinea, with introduced populations in New Zealand, Hawaii, the United Kingdom and other countries. They belong to the same Taxonomy (biology), taxonomic family as kangaroos and sometimes the same genus, but kangaroos are specifically categorised into the four largest species of the family. The term "wallaby" is an informal designation generally used for any macropod that is smaller than a kangaroo or a wallaroo that has not been designated otherwise. There are nine species (eight extant and one Extinction, extinct) of the brush wallaby (genus ''Notamacropus''). Their head and body length is and the tail is long. The 19 known species of Rock-wallaby, rock-wallabies (genus ''Petrogale'') live among rocks, usually near water; two species in this genus are endangered. The two living species of hare-wallabies (genus ''Lagorchestes''; two other species in this genus are extinct) are sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
