Palorchestes Skull
''Palorchestes'' ("ancient leaper") is an extinct genus of large terrestrial, herbivorous Australian marsupial of the family Palorchestidae, living from the Miocene through to the Late Pleistocene. Like other palorchestids, it had highly retracted nasal region suggesting that it had a prehensile lip, as well as highly unusual clawed forelimbs that were used to grasp vegetation. 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life Restoration
Paleoart (also spelled palaeoart, paleo-art, or paleo art) is any original artistic work that attempts to depict prehistoric life according to scientific evidence. Ansón, Fernández & Ramos (2015) pp. 28–34. Works of paleoart may be representations of fossil remains or imagined depictions of the living creatures and their ecosystems. While paleoart is typically defined as being scientifically informed, it is often the basis of depictions of prehistoric animals in popular culture, which in turn influences public perception of and fuels interest in these organisms. The word paleoart is also used in an informal sense as a name for prehistoric art, most often cave paintings. The term "paleoart"–which is a compound of ''paleo'', the Ancient Greek word for "old", and "art"–was introduced in the late 1980s by Mark Hallett for art that depicts subjects related to paleontology, Hallett (1987) pp. 97–113. but is considered to have originated as a visual tradition in early 1800s ...

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 Potoroidae 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proboscis
A proboscis () is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular arthropod mouthparts, mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elongated nose or snout. Etymology First attested in English in 1609 from Latin , the latinisation (literature), latinisation of the Ancient Greek (), which comes from () 'forth, forward, before' + (), 'to feed, to nourish'. The plural as derived from the Greek is , but in English the plural form ''proboscises'' occurs frequently. Invertebrates The most common usage is to refer to the tubular feeding and sucking organ of certain invertebrates such as insects (e.g., Insect mouthparts#Proboscis, moths, butterflies, and mosquitoes), worms (including Acanthocephala, Nemertea, proboscis worms) and gastropod molluscs. Acanthocephala The Acanthocephala, the thorny-headed worms or spiny-headed worms, are characterized by the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symphysis
A symphysis (, : symphyses) is a fibrocartilaginous fusion between two bones. It is a type of cartilaginous joint, specifically a secondary cartilaginous joint. # A symphysis is an amphiarthrosis, a slightly movable joint. # A growing together of parts or structures. Unlike synchondroses, symphyses are permanent. Examples The more prominent symphyses are: * the pubic symphysis * sacrococcygeal symphysis * intervertebral disc between two vertebrae * in the sternum, between the manubrium and body * mandibular symphysis In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis (Latin: ''symphysis menti'') or line of junction where the two lateral ha ..., in the jaw Symphysis disorders Pubic symphysis diastasis Pubic symphysis diastasis is an extremely rare complication that occurs in women who are giving birth. Separation of the two pubic bones during deli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koala
The koala (''Phascolarctos cinereus''), sometimes inaccurately called the koala bear, is an arboreal herbivorous marsupial native to Australia. It is the only Extant taxon, extant representative of the Family (biology), family ''Phascolarctidae''. Its closest living relatives are the wombats. The koala is found in coastal areas of the island's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria (state), Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, dark nose. The koala has a body length of and weighs . Its fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations are possibly separate subspecies, but not all researchers accept this. Koalas typically inhabit open ''Eucalyptus'' woodland, as the leaves of these trees make up mo ...

Claw
A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or Arthropod leg, tarsus for gripping a surface as they walk. The pincers of crabs, lobsters and scorpions, more formally known as their chelae, are sometimes called claws. A true claw is made of a hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense and Personal grooming, grooming, in those and other species. Similar appendages that are flat and do not come to a sharp point are called nail (anatomy), nails instead. Claw-like projections that do not form at the end of digits but spring from other parts of the foot are properly named Spur (zoology), spurs. Tetrapods In tetrapods, claws are made of keratin and ...

Horse
The horse (''Equus ferus caballus'') is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of ''Equus ferus''. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, '' Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE in Central Asia, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, which are horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ruben A
Reuben or Reuven is a Biblical male first name from Hebrew רְאוּבֵן (Re'uven), meaning "behold, a son". In the Bible, Reuben was the firstborn son of Jacob.
