Tubulidentata
Orycteropodidae is a family of afrotherian mammals. Although there are many fossil species, the only species surviving today is the aardvark, ''Orycteropus afer''. Orycteropodidae is recognized as the only family within the order Tubulidentata (Latin: "tube" (tubulis), "tooth" (dentis)), so the two are effectively synonyms. Evolution The first aardvark fossil discovered was originally named ''Orycteropus gaudryi'' (now ''Amphiorycteropus'') and was found in Turolian deposits on the island of Samos. Since then, representatives of the order Tubulidentata have been located from the Oligocene in what is now Europe, and it is believed that the order probably originated around 65–70 million years ago or in the Paleocene. They are thought to be closely related to the now extinct Ptolemaiida, a lineage of carnivorous afrotheres. The family arose in Africa in the Early Miocene epoch, and spread to Eurasia later in the Miocene. Most of the family's diversity had become extinct by the ...

Aardvark
The aardvark ( ; ''Orycteropus afer'') is a medium-sized, burrowing, nocturnal mammal native to Africa. It is the only living species of the order Tubulidentata, although other prehistoric species and genera of Tubulidentata are known. Unlike most other insectivores, it has a long pig-like snout, which is used to sniff out food. It roams over most of the southern two-thirds of the African continent, avoiding areas that are mainly rocky. A nocturnal feeder, it subsists on ants and termites, which it will dig out of their hills using its sharp claws and powerful legs. It also digs to create burrows in which to live and rear its young. The animal is listed as "least concern" by the IUCN, although its numbers are decreasing. Aardvarks are afrotheres, a clade which also includes elephants, manatees, and hyraxes. Name and taxonomy Name The aardvark is sometimes colloquially called the "African ant bear", "anteater" (not to be confused with the anteater, South American anteater), ...

Amphiorycteropus
''Amphiorycteropus'' (Latin for "near aadvark") or the wooly aadvark is an extinct genus of mammals in the family Orycteropodidae within Tubulidentata. The genus is known from fossils dating from Middle Miocene to Early Pliocene, found in Africa, Asia and Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions.

Afrotheria
Afrotheria ( from Latin ''Afro-'' "of Africa" + ''theria'' "wild beast") is a clade of mammals, the living members of which belong to groups that are either currently living in Africa or of African origin: golden moles, elephant shrews (also known as sengis), tenrecs, aardvarks, hyraxes, elephants, sea cows, and several extinct clades. Most groups of afrotheres share little or no superficial resemblance, and their similarities have only become known in recent times because of genetics and molecular studies. Many afrothere groups are found mostly or exclusively in Africa, reflecting the fact that Africa was an island continent from the Cretaceous until the early Miocene around 20 million years ago, when Afro-Arabia collided with Eurasia. Because Africa was isolated by water, Laurasian groups of mammals such as insectivores, rodents, lagomorphs, carnivorans and ungulates could not reach Africa for much of the early to mid-Cenozoic. Instead, the niches occupied by those groups on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptolemaiida
Ptolemaiida is a taxon of wolf-sized afrothere mammals that lived in northern and eastern Africa during the Paleogene. The oldest fossils are from the latest Eocene strata of the Jebel Qatrani Formation, near the Fayum oasis in Egypt. A tooth is known from an Oligocene-aged stratum in Angola, and Miocene specimens (of '' Kelba'') are known from Kenya and Uganda The origin of the Ptolemaiida is obscure, and debated. The type species was originally thought to be a primate, but, later, when elongated skulls with long canines of ''Ptolemaia'' and '' Qarunavus'' were found, they were then thought to be hyaenodontids, or giant, carnivorous relatives of the pantolestids '' Palaeosinopa'', and of modern shrews The family Ptolemaiidae was elevated to order level in 1995, although some experts later placed the Ptolemaiidae within the pantolestids. Recently, Ptolemaiida has been placed within Afrotheria on the basis of paleobiology, as the taxon was endemic to Africa, and because of so ...

Anatomical Terms Of Location
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Tibia
The tibia (; ), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle. The tibia is found on the medial side of the leg next to the fibula and closer to the median plane. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute ''tibia''. It is the second largest bone in the human body, after the femur. The leg bones are the strongest long bones as they support the rest of the body. Structure In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints. The ossification or formation of the bone ...

Myrmecophagy
Myrmecophagy is a feeding behavior defined by the consumption of termites or ants, particularly as pertaining to those animal species whose diets are largely or exclusively composed of said insect types. Literally, myrmecophagy means "ant eating" (Ancient Greek: ', "ants" and ', "to eat") rather than "termite eating" (for which the strict term is termitophagy). The two habits often overlap, as both of these eusocial insect types often live in large, densely populated nests requiring similar adaptations in the animal species that exploit them. In vertebrates Myrmecophagy is found in a number of land-dwelling vertebrate taxa, including reptiles and amphibians (horned lizards and blind snakes, narrow-mouthed toads of the family Microhylidae and poison frogs of the Dendrobatidae), a number of New World bird species (Antbirds, Antthrushes, Antpittas, flicker of genus ''Colaptes''), and several mammalian groups (anteaters, aardvarks, aardwolves, armadillos, echidnas, numbats, pangolins ...

Diaphysis
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs. Ewing sarcoma tends to occur at the diaphysis.Physical Medicine and Rehabilitation Board Review, Cuccurullo Additional images Illu long bone.jpg File:EpiMetaDiaphyse.jpg, Long bone See also *Epiphysis *Metaphysis The metaphysis is the neck portion of a long bone between the epiphysis and the diaphysis.
