Archerus
''Archerus'' is a genus of extinct marsupials from Miocene Australia. It is known from jawbones and partial skulls from the Riversleigh World Heritage Area in Queensland, dated to between . These are sufficient to identify it as a phalangerid, perhaps more closely related to the brushtail possums than to the cuscuses, but with many distinctive skeletal features that make the latter relationship uncertain; it may have lived before the two branches of the living family diverged from one another. It is estimated to have weighed around , similar to the living scaly-tailed possum, and the shape of its teeth suggest that it had a similarly omnivorous An omnivore () is an animal that regularly consumes significant quantities of both plant and animal matter.

Phalangeridae
The Phalangeridae are a family of mostly nocturnal marsupials native to Australia, New Guinea, and Eastern Indonesia, including the cuscuses, brushtail possums, and their close relatives. Considered a type of possum, most species are arboreal, and they inhabit a wide range of forest habitats from alpine woodland to eucalypt forest and tropical jungle. Many species have been introduced to various non-native habitats by humans for thousands of years. Characteristics Phalangerids are relatively large, compared with other possums. The smallest species, the Sulawesi dwarf cuscus, is cat-sized, averaging in length, while the largest, the black-spotted cuscus, is around long, and weighs . Besides the large size, other key features distinguishing phalangerids from other possums include the presence of bare skin on at least part of the tail, and low-crowned molar teeth. They have claws on the fore feet, but none on the hind feet, although these do have an opposable first toe to help ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Dentary
In jawed vertebrates, the mandible (from the Latin ''mandibula'', 'for chewing'), lower jaw, or jawbone is a bone that makes up the lowerand typically more mobilecomponent of the mouth (the upper jaw being known as the maxilla). The jawbone is the skull's only movable, posable bone, sharing joints with the cranium's temporal bones. The mandible hosts the lower teeth (their depth delineated by the alveolar process). Many muscles attach to the bone, which also hosts nerves (some connecting to the teeth) and blood vessels. Amongst other functions, the jawbone is essential for chewing food. Owing to the Neolithic advent of agriculture (), human jaws evolved to be smaller. Although it is the strongest bone of the facial skeleton, the mandible tends to deform in old age; it is also subject to fracturing. Surgery allows for the removal of jawbone fragments (or its entirety) as well as regenerative methods. Additionally, the bone is of great forensic significance. Structure ...

Riversleigh World Heritage Area
Riversleigh World Heritage Area is Australia's most famous fossil location, recognised for the series of well preserved fossils deposited from the Late Oligocene to more recent geological periods. The fossiliferous limestone system is located near the Gregory River in the north-west of Queensland, an environment that was once a very wet rainforest that became more arid as the Gondwanan land masses separated and the Australian continent moved north. The approximately area has fossil remains of ancient mammals, birds, and reptiles of the Oligocene and Miocene ages, many of which were discovered and are only known from the Riversleigh area; the species that have occurred there are known as the Riversleigh fauna. The fossils at Riversleigh are unusual because they are found in soft freshwater limestone which has not been compacted. This means the animal remains retain their three-dimensional structure, rather than being partially crushed like in most fossil sites. The area is loc ...

Brushtail Possum
The brushtail possums are the members of the genus ''Trichosurus'' in the Phalangeridae, a family of marsupials. They are native to Australia (including Tasmania) and some small nearby islands. Unique among marsupials, they have shifted the hypaxial muscles from the epipubic to the pelvis, much like in placental mammals, meaning that their breathing cycle is more similar to the latter than to that of other non-eutherian mammals. In general, they are more terrestrially oriented than other possums, and in some ways might parallel primates. The genus contains these species: * Northern brushtail possum, ''T. arnhemensis'' * Short-eared possum, ''T. caninus'' * Mountain brushtail possum, ''T. cunninghami'' * Coppery brushtail possum, ''T. johnstonii'' *Common brushtail possum The common brushtail possum (''Trichosurus vulpecula'', from the Ancient Greek, Greek for "furry tailed" and the Latin for "little fox", previously in the genus ''Phalangista'') is a nocturnal, semiarbore ...

Cuscus
Cuscus ( or ) is the common name generally given to the species within the four genera of Australasian possum of the family Phalangeridae with the most tropical distribution: * '' Ailurops'' * '' Phalanger'' * '' Spilocuscus'' * '' Strigocuscus'' The name comes from the word ''kusu'' or ''kuso'' in some local related languages spoken in the Maluku Islands like Bacan and Ambonese Malay. It is also applied in parts of Indonesia to the Sunda slow loris, where people do not distinguish this from the "kuskus" possums. Note however, that the loris, being a primate, is unrelated to the other cuscus species. Cuscus are marsupials, even though they have some appearances, traits and attributes like those of lemurs of Madagascar, which are prosimians, due to convergent evolution.

Scaly-tailed Possum
The scaly-tailed possum (''Wyulda squamicaudata'') is found in northwestern Australia, where it is restricted to the Kimberley. They are light grey over most of the body and have relatively short ears and muzzle. The mostly hairless tail is able to curl around the branches of trees as the possum forages for food, its grasp is aided by rasp-ilke scales and is strong enough to hold its own weight. The species favours complex rocky terrain with dense thickets of vines and the fruiting trees that provide much of their diet. Taxonomy The new species was presented to the Royal Society of Western Australia in 1918 by the biologist Wilfred Backhouse Alexander, while he was employed by the Western Australian Museum, and published in the society's journal in the same year. The description was accompanied by a reproduction of a painting by George Pitt Morison, and two photographs of the specimen's skull were also included. The holotype was reported to have been collected in the Kimberle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omnivorous
An omnivore () is an animal that regularly consumes significant quantities of both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms ( Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. ...
