Potoridae
Potoroidae is a family of marsupials, small Australian animals known as Bettong, bettongs, Potoroo, potoroos, and rat-kangaroos. All are rabbit-sized, brown, jumping marsupials and resemble a large rodent or a very small wallaby. Taxonomy The potoroids are smaller relatives of the kangaroos and wallabies, and may be ancestral to that group. In particular, the teeth show a simpler pattern than in the Macropodidae, kangaroo family, with longer upper incisors, larger canine (tooth), canines, and four cusps on the Molar (tooth), molars. However, both groups possess a wide diastema (dentistry), diastema between the incisors and the cheek teeth, and the potoroids have a similar dental formula to their larger relatives: In most respects, however, the potoroids are similar to small wallabies. Their hind feet are elongated, and they move by hopping, although the adaptations are not as extreme as they are in true wallabies, and, like rabbits, they often use their fore limbs to move abou ...

Diprotodontia
Diprotodontia (, from Greek language, Greek "two forward teeth") is the largest extant order (biology), order of marsupials, with about 155 species, including the kangaroos, Wallaby, wallabies, Phalangeriformes, possums, koala, wombats, and many others. Extinct diprotodonts include the hippopotamus-sized ''Diprotodon'', and ''Thylacoleo'', the so-called "marsupial lion". Characteristics Living diprotodonts are almost all herbivores, as were most of those that are now extinct. A few insectivore, insectivorous and omnivore, omnivorous diprotodonts are known, and the Potoridae are almost unique among vertebrates in being largely Fungivore, fungivorous, but these seem to have arisen as relatively recent adaptations from the mainstream herbivorous lifestyle. The extinct Thylacoleonidae, thylacoleonids ("marsupial lions") are the only known group to have exhibited Carnivore, carnivory on a large scale. Diprotodonts are restricted to Australasia. The earliest known fossils date to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bettong
Bettongs, species of the genus ''Bettongia'', are potoroine marsupials once common in Australia. They are important ecosystem engineers displaced during the colonisation of the continent, and are vulnerable to threatening factors such as altered fire regimes, land clearing, pastoralism and introduced predatory species such as the fox and cat. Conservation status All species of the genus have been severely affected by ecological changes since the European settlement of Australia. Those that have not become extinct became largely confined to islands and protected reserves and are dependent on re-population programs. The diversity of the genus was poorly understood before their extirpation from the mainland, and new taxa have been identified in specimens newly discovered and already held in museum collections. In 2021 August, 40 Bettongs were released in different parts of South Australia; they were raised in captivity to increase their numbers. Taxonomy Four extant species ar ...

Herbivorous
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material. A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This flora is made up of cellulose-digesting protozoans or bacteria. Etymology Herbivore is the anglicized form of a modern Latin coinage, ''herbivora'', cited in Charles Lyell's 1830 ''Principles of Geology''.J.A. Simpson and E.S.C. Weiner, eds. (2000) ''The Oxford English Dictionary'', vol. 8, p. 155. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. ''Herbivora'' is derived from Latin ''herba' ...

Borungaboodie
''Borungaboodie'' is an extinct genus of potoroo that lived in Southwest Australia during the Pleistocene. The genus is represented by a single species known as ''Borungaboodie hatcheri'', or more informally, the giant potoroo. Discovery and naming Remains of ''Borungaboodie'' were found in Tight Entrance Cave in southwestern Australia. While the cave was explored since the 1970s, it wasn't until 1991 that Lindsay Hatcher and his team at the Western Australian Speleological Group (WASG) discovered that the cave contains fossils of extinct species. The first fossils of ''Borungaboodie'' were subsequently discovered in 1996. The name ''Borungaboodie'' is derived from the Nyoongar ''borunga'', meaning "very big", and ''boodie'' the word for the living bettong. The specific name honors Hatcher. Description ''Borungaboodie'' was significantly larger than any living potoroo, reaching a size comparable to that of a koala The koala or, inaccurately, koala bear (''Phascolarctos ...

Rufous Rat-kangaroo
The rufous rat-kangaroo or rufous bettong (''Aepyprymnus rufescens'') is a small, jumping, rat-like mammal native to eastern Australia. It is the only species in the genus ''Aepyprymnus''. The largest member of the rat-kangaroo family (Potoroidae), it is about the size of a rabbit. The rufous rat-kangaroo is active at night when it digs for plant roots and fungi, and like other marsupials it carries its young in a pouch. Though its range is reduced, the population is healthy and stable. Taxonomy The rufous rat-kangaroo is the only member of its genus, and is the largest of all the potoroids. It is generally grey with a hint of reddish brown and its scientific name means "reddish high-rump". It was once thought of as a solitary, nocturnal animal, but recent observation indicates that the rufous rat-kangaroo may form loose, polygynous associations. It feeds mostly on tubers and fungi, but also on leaves and other vegetation. Description A species of the family Potoroidae (rat ...

Their hind feet are elongated, and they move by hopping, although the adaptations are not as extreme as they are in true wallabies, and, like rabbits, they often use their fore limbs to move about at slower speeds. The potoroids are, like nearly all diprotodonts, herbivorous. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeopotorous
''Palaeopotorous priscus'' is a fossil species of a diprotodont marsupial, known from specimens obtained in central Australia. The animal was similar to the modern species of the family Potoroidae, the potoroos and bettongs. Taxonomy The only known species of its genus, ''Palaeopotorous'', which has been allied to the subfamily Potoroinae or as the type of a subfamily, Palaeopotoroinae, in the potoroid family. Description The dental evidence of the species indicates it was a similar size to a small to medium 'rat-kangaroos' that were common into the twentieth century. Since its first discovery, the species has been suspected of representing an early lineage of the macropods. The finds have been placed to the late Oligocene 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 ... pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bettongia Gaimardi
The eastern bettong (''Bettongia gaimardi''), also known as the southern or Tasmanian bettong, is a small, hopping, rat-like mammal native to grassy forests of southeastern Australia and Tasmania. A member of the rat-kangaroo family (Potoroidae), it is active at night and feeds on fungi and plant roots. Like other marsupials, it carries its young in a pouch. The eastern bettong is under pressure by introduced predators and habitat loss. The subspecies on mainland Australia (''B. g. gaimardi'') is extinct, but populations of the Tasmanian subspecies (''B. g. cuniculus'') have been reintroduced there.Rose, R. (1997). Metabolic rate and thermal conductance in a mycophagous marsupial, ''Bettongia gaimardi'''. The World Wide Web Journal of Biology 2: 2-7. The animal is called ''balbo'' by the Ngunnawal, an Aboriginal people who used to keep them as pets.
