Sthenurinae
Sthenurinae (from ''Sthenurus'', Greek for 'strong-tailed') is a subfamily within the marsupial family Macropodidae, known as 'short faced kangaroos'. No members of this subfamily are extant today, with all becoming extinct by the late Pleistocene. ''Procoptodon goliah'', the largest macropodid known to have existed, was a sthenurine kangaroo, but sthenurines occurred in a range of sizes, with '' Procoptodon gilli'' being the smallest at the size of a small wallaby. The short, robust skull of sthenurines is considered to be indicative that they were browsers that fed on leaves. Some species may have been able to reach above their heads and grasp branches with their semiopposable paws to assist in procuring leaves from trees. A single hoofed digit is present on the feet of sthenurines. Taxonomy The subfamilial arrangement Sthenurinae was circumscribed by Ludwig Glauert in 1926. Locomotion Unlike modern macropodids, which hop (either bipedally or quadrupedally), sthenurines seem t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature (journal)
''Nature'' is a British weekly scientific journal founded and based in London, England. As a multidisciplinary publication, ''Nature'' features peer-reviewed research from a variety of academic disciplines, mainly in science and technology. It has core editorial offices across the United States, continental Europe, and Asia under the international scientific publishing company Springer Nature. ''Nature'' was one of the world's most cited scientific journals by the Science Edition of the 2019 ''Journal Citation Reports'' (with an ascribed impact factor of 42.778), making it one of the world's most-read and most prestigious academic journals. , it claimed an online readership of about three million unique readers per month. Founded in autumn 1869, ''Nature'' was first circulated by Norman Lockyer and Alexander Macmillan as a public forum for scientific innovations. The mid-20th century facilitated an editorial expansion for the journal; ''Nature'' redoubled its efforts in exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcoota Fauna
__NOTOC__ The Alcoota Fossil Beds are an important paleontological Lagerstätte in the Northern Territory of Australia located on Alcoota Station in the locality of Anmatjere about north-east of Alice Springs in the Central Australia region. It is notable for the occurrence of well-preserved, rare, Miocene vertebrate fossils, which provide evidence of the evolution of the Northern Territory’s fauna and climate. The Alcoota Fossil Beds are also significant as a research and teaching site for palaeontology students. The Alcoota deposit is a series of intermittently interconnected lakes within a large basin. Evidence suggests that the concentration of fossils is due to a phenomenon called ‘waterhole-tethering’: During dry periods, animals concentrated in the immediate area of the continually shrinking, spring-fed lake, resulting in the death of many animals. The Alcoota and Bullock Creek fossil faunas provide evidence that aridification was in progress in northern Austr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Kanunka
__NOTOC__ The Lake Ngapakaldi to Lake Palankarinna Fossil Area is a group of fossil sites located in the Australian state of South Australia within the Tirari Desert in the north-eastern part of the state's Far North (South Australia), Far North region. The group has an overall area of and is located about east of Lake Eyre and about north-north-east of Marree, South Australia, Marree, off the Birdsville Track near Etadunna Station. Description The area consists of four lakes grouped into two areas located about apart. They are surrounded by extensive areas of sand dunes in a flat, arid landscape. The lake beds are largely unvegetated and usually dry. Low cliffs on the western margins of the lakes have produced a variety of Tertiary vertebrate fossils ranging in age from the late Oligocene to the Pleistocene. Lakes Kununka, Ngapakaldi and Pitikanta The following three lakes are located on the west side of the gazetted locality of Mulka, South Australia, Mulka with Lak ...

Prehistoric Macropods
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pleistocene Marsupials
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Taxa Named By Richard Owen
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
