Palorchestids
Palorchestidae is an extinct family of diprotodont marsupials whose members are sometimes referred to as marsupial tapirs due to their superficial similarity to true tapirs. Genera The family consists of the following four genera: * '' Propalorchestes'' (Murray, 1986) * ''Ngapakaldia ''Ngapakaldia'' is an extinct genus of diprotodontid marsupials, related to the modern koala and wombat.

Palorchestes
''Palorchestes'' ("ancient leaper or dancer") is an extinct genus of terrestrial, herbivorous marsupials of the family Palorchestidae. The genus was endemic to Australia, living from the Miocene through to the Pleistocene epochs. Taxonomy The generic name was coined in 1873 by anatomist Richard Owen, who first found what he thought was the fragmentary jaw of a prehistoric kangaroo and derived the name from ancient Greek terms for "ancient" and "leaper". Despite Owen explicitly stating the etymology of the name in his description, palaeontologist Harold Fletcher published a translation as "the ancient dancer" in 1945. When more postcranial elements were found, ''Palorchestes'' was realized as not a macropod, but a diprotodontid. Owen's description as a giant kangaroo was revised in 1958 by Jack T. Woods of the Queensland Museum, allying the genus to the Diprotodontia order. Another genus is probably ancestral to these species, thus named ''Propalorchestes''; it shared some c ...

Diprotodont
Diprotodontia (, from Greek "two forward teeth") is the largest extant 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 late Oligocene, but their genesi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsupial
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, bandicoots, and the extinct thylacine. Marsupials represent the clade originating from the last common ancestor of extant metatherians, the group containing all mammals more closely related to marsupials than to placentals. They give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time. Close to 70% of the 334 extant species occur on the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 30% are found in the Americas—primarily in South America, thirteen in Central America, and one species, the Virginia opossum, in Nort ...

Tapir
Tapirs ( ) are large, herbivorous mammals belonging to the family Tapiridae. They are similar in shape to a pig, with a short, prehensile nose trunk. Tapirs inhabit jungle and forest regions of South and Central America, with one species inhabiting Southeast Asia. They are one of three extant branches of Perissodactyla (odd-toed ungulates), alongside equines and rhinoceros. Only a single genus, ''Tapirus'' is currently extant. Tapirs migrated into South America during the Pleistocene epoch from North America after the formation of the Isthmus of Panama as part of the Great American Interchange. Tapirs were once widespread in North America until the arrival of humans at the end of the Late Pleistocene, around 12,000 years ago. Species There are four widely recognized extant species of tapir, all in the genus ''Tapirus'' of the family Tapiridae. They are the South American tapir, the Malayan tapir, Baird's tapir, and the mountain tapir. In 2013, a group of researchers sai ...

Propalorchestes
''Propalorchestes'' is a fossil genus of Diprotodontidae, mammals that existed in Australia. Overview The type species is ''Propalorchestes novaculacephalus''. The genus is probably ancestral to ''Palorchestes'' and resembles ''Ngapakaldia'', another palorchestid that existed during the Miocene epoch. Evidence for the transitional connection between earlier and later phylogenies was discovered amongst the Riversleigh fauna, including a more complete maxilla within the unworn dentition of a juvenile. The marsupial appears to have existed from the early to mid Miocene in material obtained in north-eastern Queensland, in fossil deposits at Riversleigh. A largely complete cranium, providing anatomical evidence of the rostral morphology that distinguished the lineage of ''Propalorchestes'' and ''Palorchestes'' from similar groups of the diprotodont order of marsupials. The dentition of the specimen links the form of molars found in the early wynyardiids with those of the palorchest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ngapakaldia
''Ngapakaldia'' is an extinct genus of diprotodontid marsupials, related to the modern koala and wombat. Around the size of a sheep, it was a ground-dwelling herbivore that lived around the vegetated shores of lakes in Central Australia during the Late Oligocene. The genus was established in 1967 by R. A. Stirton when describing a fossil species ''Ngapakaldia tedfordi''. The name refers to the source of the type material, Lake Ngapakaldi, located in Lake Ngapakaldi to Lake Palankarinna Fossil Area __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 region.

Prehistoric Vombatiforms
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] |

Miocene Marsupials
The Miocene ( ) is the first 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 is preceded by the Oligocene and is followed by 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 a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.
