Short-nosed Bandicoot
The short-nosed bandicoots (genus ''Isoodon'') are members of the order (biology), order Peramelemorphia. These marsupials can be found across Australia, although their distribution can be patchy. Genetic evidence suggests that short-nosed bandicoots diverged from the related Perameles, long-nosed species around eight million years ago, during the Miocene epoch, and underwent a rapid diversification around three million years ago, during the late Pliocene. Species and subspecies While the IUCN lists only three species in this genus, as many as five species in this genus with the two subspecies of ''I. obesulus'' raised to full species. *Golden bandicoot, ''Isoodon auratus'' *Northern brown bandicoot, ''Isoodon macrourus'' *Southern brown bandicoot, ''Isoodon obesulus'' **Quenda or Western brown bandicoot, ''Isoodon obesulus fusciventer'' **Cape York brown bandicoot, ''Isoodon obesulus peninsulae'' References Peramelemorphs Marsupials of Australia Miocene marsupials Mioc ...

Isoodon Obesulus
The southern brown bandicoot (''Isoodon obesulus'') is a short-nosed bandicoot, a type of marsupial, found mostly in southern Australia. A subspecies in Western Australia is also known as the quenda in Southwest Australia, South Western Australia (from the Noongar language, Noongar word ''). This subspecies was elevated to species in 2018. Taxonomy George Shaw (biologist), George Shaw described the species as ''Didelphis obesula'' in 1797. While some authorities list as few as two subspecies (''I. o. obesulus'' and ''I. o. nauticus''), there are currently five recognised species: * ''Isoodon obesulus nauticus'' - restricted to the Nuyts Archipelago * ''Isoodon obesulus obesulus'' - NSW, Victoria, SA * ''Isoodon obesulus peninsulae'' - Cape York Peninsula * ''Isoodon obesulus affinus'' - Tasmania and Bass Strait Islands * ''Isoodon obesulus fusciventer''- southwest WA.

Miocene
The Miocene ( ) is the first epoch (geology), 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 followed the Oligocene and preceded 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 distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marsupials Of Australia
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 kangaroos, koalas, opossums, possums, Tasmanian devils, wombats, wallabies, and 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 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 continent, including mainland Australia, Tasmania, New Guinea, and nearby islands. The remainin ...

Peramelemorphs
The order Peramelemorphia includes the bandicoots and bilbies. All members of the order are endemic to Australia-New Guinea and most have the characteristic bandicoot shape: a plump, arch-backed body with a long, delicately tapering snout, very large upright ears, relatively long, thin legs, and a thin tail. Their size varies from about 140 grams up to 4 kilograms, but most species are about one kilogram. Phylogeny Placement within Marsupialia The position of the Peramelemorphia within the marsupial family tree has long been puzzling and controversial. There are two morphological features in the order that appear to show a clear evolutionary link with another marsupial group: the type of foot, and the teeth. Unfortunately, these clear signposts point in opposite directions. All members of the order are polyprotodont (have several pairs of lower front teeth)—in the case of the Peramelemorphia, three pairs. This suggests that they have evolved within Dasyuromorphia (mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape York Brown Bandicoot
A cape is a clothing accessory or a sleeveless outer garment of any length that hangs loosely and connects either at the neck or shoulders. They usually cover the back, shoulders, and arms. They come in a variety of styles and have been used throughout history for many different reasons. Semantic distinction In fashion, the word "cape" usually refers to a shorter garment and "cloak" to a full-length version of the different types of garment, though the two terms are sometimes used synonymously for full-length coverings. A shoulder cape is thus sometimes called a "capelet". The fashion cape does not cover the front to any appreciable degree. In raingear, a cape is usually a long and roomy protective garment worn to keep one dry in the rain. History The first known usage of capes is unknown, but some early references we know of are from Ancient Roman military uniforms. Later on, capes were common in medieval Europe, especially when combined with a hood in the chaperon. They h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quenda
The quenda (''Isoodon fusciventer''), also known as the southwestern brown bandicoot or western brown bandicoot, is a small marsupial species endemic to Southwest Australia. Though it was originally treated as a subspecies of the southern brown bandicoot (''Isoodon obesulus''), such as by the IUCN where it is given the status of least concern, a 2018 paper proposed to raise it to species rank due to molecular and morphological analysis which revealed it was more closely related to the golden bandicoot (''Isoodon auratus''). It is currently recognised as a separate species by the ASM Mammal Diversity Database, the Australian Faunal Directory and the Atlas of Living Australia. Quenda are one of the few native marsupials that can still be seen in Perth's urban bushland reserves. They are vulnerable to predation by feral foxes and cats and quenda populations can recover where predators are controlled. Description Quenda are small marsupials with a long pointed muzzle; they are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Brown Bandicoot
The northern brown bandicoot (''Isoodon macrourus''), a marsupial species, is a bandicoot found only on the northern and eastern coasts of Australia and nearby islands, mainly Papua New Guinea. It is not, however, found far inland. Description This species can be set apart from other marsupials by two traits; it is both polyprotodont (i.e., several pairs of lower front teeth) and syndactylous. The northern brown bandicoot has typical body and tail lengths of , respectively. On average it weighs . This marsupial has a thick harsh coat but is not spiny. The dorsal pelage is light brown in appearance with speckled black patterns throughout. On the ventral surface it is solid white. The northern brown bandicoot has a reverse pouch so it won't fill with soil when digging. This bandicoot also has short, rounded ears and a short nose. One can easily mistake the northern brown bandicoot for the southern brown bandicoot. The two species differ in both size, with the northern brown ban ...

Golden Bandicoot
The golden bandicoot (''Isoodon auratus''; Yolngu: ''Wan'kurra'') is a short-nosed bandicoot found in northern Australia. It is the smallest of its genus, and is distinguished from the brown bandicoots by its golden colouring and much smaller size. It was once found throughout much of northern, central and western Australia, into south-western New South Wales, but it is now restricted to a few areas in Western Australia (WA) and the Northern Territory (NT). The ''I. auratus auratus'' subspecies, also known as the golden bandicoot (mainland), is found in the Kimberley region of WA, and on three of the Wessel Islands, NT: Marchinbar, Raragala, and Guluwuru Islands. Another subspecies, ''I. auratus barrowensis'' or golden bandicoot (Barrow Island), is found on Augustus, Barrow and Middle Islands off Western Australia (''I. auratus barrowensis''). the classification into subspecies is debated; however the whole species is classed as vulnerable species.

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
