Liyamayi Dayi
''Liyamayi dayi'' is a mammal species of the Thylacomyidae family known from fossils located at the Riversleigh World Heritage Area in northeast Australia. The discovery of the specimens was identified as deposited around fifteen million years ago, revising the earliest record of this peramelemorphian lineage from those of species that existed around ten million years later. Taxonomy A fossil species assigned to a new genus, ''Liyamayi'', in a description by researchers at the Riversleigh fossil area, K. J. Travouillon, S. J. Hand , M. Archer and K. H. Black, who identified distinctions in the dentition from other named genera, for a new species of Riversleigh fauna was published in 2014, the authors proposing the specific epithet for Robert Day in gratitude for support toward the research project. The gender of the genus name ''Liyamayi'' is stated to be masculine, and combines two terms from the Waanyi language, spoken by peoples of the Riversleigh region, ''liya'' and ''m ...

Thylacomyidae
''Macrotis'' is a genus of desert-dwelling marsupial omnivores known as bilbies or rabbit-bandicoots; Unabridged they are members of the order Peramelemorphia. At the time of European colonisation of Australia, there were two species. The lesser bilby became extinct in the 1950s; the greater bilby survives but remains endangered. It is currently listed as a vulnerable species. The greater bilby is on average long, excluding the tail, which is usually around long. Its fur is usually grey or white; it has a long, pointy nose and very long ears, hence the reference of its nickname to rabbits. Taxonomy ''Macrotis'' means ‘big-eared’ ( + ‘ear’) in Greek, referring to the animal's large, long ears. The genus name was first proposed as a subgeneric classification, which after a century of taxonomic confusion was eventually stabilised as the accepted name in a 1932 revision by Ellis Troughton. In reviewing the systematic arrangement of the genus, Troughton recognised ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 locat ...

Riversleigh Fauna
Riversleigh fauna is the collective term for any species of animal identified in fossil sites located in the Riversleigh World Heritage Area. Faunal zones The presence of the Riversleigh in the Oligo-Miocene has been exceptionally well preserved throughout a number of time periods. These has been classified by four "faunal zones", and may be summarised as, * Faunal Zone A (FZA): late Oligocene, a period 23.03–28.4 million years before present * Faunal Zone B (FZB): early Miocene, 15.97-23.03 myr * Faunal Zone C (FZC): middle Miocene, 11.608-15.97 myr * Faunal Zone D (FZD): late Miocene, 5.332-11.608 myr More recent fossil specimens has also been coded to the period of deposition, * Pliocene (PLIO), a period 2.588-5.332 myr * Pleistocene (PLEIS), 0.0117-2.588 myr * Holocene, noted as (HOLO) to indicate the period dated as following the Pleistocene, from the present day to 11,700 years ago. Faunal lists The following are incomplete lists of mammals, birds, fish, and invertebr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waanyi
The Waanyi people, also spelt Wanyi, Wanji, or Waanji, are an Aboriginal Australian people from south of the Gulf of Carpentaria in Queensland and the Northern Territory. Language The Waanyi language, although earlier thought to be extinct, was found in the 2016 Australian census to have 16 speakers. This was down from the recorded peak of 40 in the 2011 Australian census. It is classified as one of the Garrwan languages. Country The Waanyi territory was in well-watered limestone and sandstone country, including parts of the Gregory River. In Norman Tindale's estimation, the Waanyi held about of territory, extending from the vicinity of the south of the upper Nicholson River, west of Corinda, and at Spring and Lawn Hill creeks. Their eastern extension lay at the Barkly (Barclay) River, Lawn Hill and Bannockburn. Their western frontier was at Old Benmara, and south-west they roamed as far as Mount Morgan. They lay south of the Kunindiri and Garrwa people, west of the Inji ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaeropodidae
''Chaeropus'', known as the pig-footed bandicoots, is a genus of small mammals that became extinct during the 20th century. They were unique marsupials, of the order Peramelemorphia (bandicoots and bilbies), with unusually thin legs, yet were able to move rapidly. Two recognised species inhabited dense vegetation on the arid and semiarid plains of Australia. The genus' distribution range was later reduced to an inland desert region, where it was last recorded in the 1950s; it is now presumed extinct. Taxonomy The genus was proposed by William Ogilby in a presentation to the Linnean Society of London of a new species tentatively assigned to a genus of bandicoots, the long-nosed ''Perameles'', and was forwarded to John Gould, then at Sydney, for a more detailed examination. Ogilby submitted a drawing by collector Major Mitchell, who also supplied extensive remarks on the animal's form and habits, and identified the unusual pig-like toes of the forelimbs as the basis for a new genu ...

Peramelidae
The marsupial family Peramelidae contains all of the extant bandicoots. They are found throughout Australia and New Guinea, with at least some species living in every available habitat, from rainforest to desert. Four fossil peramelids are described. One known extinct species of bandicoot, the pig-footed bandicoot, was so different from the other species, it was recently moved into its own family. Characteristics Peramelids are small marsupials, ranging in size from the mouse bandicoot, which is 15-17.5 cm long, to the giant bandicoot, which at 39–56 cm in length and up 4.7 kg in weight, is about the size of a rabbit. They have short limbs and tails, smallish, mouse-like ears, and a long, pointed snout. Peramelids are omnivorous, with soil-dwelling invertebrates forming the major part of their diet; they also eat seeds, fruit, and fungi. Their teeth are correspondingly unspecialised, with most species having the dental formula Female peramelids have a pouch th ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Alveolus
Dental alveoli (singular ''alveolus'') are sockets in the jaws in which the roots of teeth are held in the alveolar process with the periodontal ligament. The lay term for dental alveoli is tooth sockets. A joint that connects the roots of the teeth and the alveolus is called ''gomphosis'' (plural ''gomphoses''). Alveolar bone is the bone that surrounds the roots of the teeth forming bone sockets. In mammals, tooth sockets are found in the maxilla, the premaxilla, and the mandible. Etymology 1706, "a hollow," especially "the socket of a tooth," from Latin alveolus "a tray, trough, basin; bed of a small river; small hollow or cavity," diminutive of alvus "belly, stomach, paunch, bowels; hold of a ship," from PIE root *aulo- "hole, cavity" (source also of Greek aulos "flute, tube, pipe;" Serbo-Croatian, Polish, Russian ulica "street," originally "narrow opening;" Old Church Slavonic uliji, Lithuanian aulys "beehive" (hollow trunk), Armenian yli "pregnant").
