Tapirus Mesopotamicus
''Tapirus mesopotamicus'' is an extinct species of tapir that lived in South America during the Pleistocene. It is considered a possible ancestor of all extant South American tapirs. Description This species was originally described by B. S. Ferrero and J. I. Noriega in 2007. Their description was based on quite complete cranial pieces exhumed from sediments of the Luján River in the Diamante department, in the province of Entre Ríos, in central-eastern Argentina. The type specimen is CICYTTP-PV-M-1-23, a skull and proximal fragment of the right jaw. Its type locality is the north bank of the Ensenada stream, on a Pleistocene lake-fluvial horizon in the "Arroyo Feliciano formation" of Argentina. It is described as having a long and robust skull, with a short rostrum with respect to the total length of the skull. The skull has a single, non-arched sagittal crest, large flat parietal bones on the anterior skull cover, with the temporal crests converging very close to the fr ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), 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 Great American Interchang ...

Mandibular Condyle
The condyloid process or condylar process is the process on the human and other mammalian species' mandibles that ends in a condyle, the mandibular condyle. It is thicker than the coronoid process of the mandible and consists of two portions: the condyle and the constricted portion which supports it, the neck. Condyle The most superior part of the mandible, the condyle presents an articular surface for articulation with the articular disk of the temporomandibular joint; it is convex from before backward and from side to side, and extends farther on the posterior than on the anterior surface. Its long axis is directed medialward and slightly backward, and if prolonged to the middle line will meet that of the opposite condyle near the anterior margin of the foramen magnum. At the lateral extremity of the condyle is a small tubercle for the attachment of the temporomandibular ligament. The articular surface of the condyle is covered by fibrous tissue, and interfaces with an articu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tapirus Rondoniensis
''Tapirus rondoniensis'' is an extinct species of large sized tapir that lived in northwestern parts of Brazil during the Pleistocene. Fossils of the species were found in the Río Madeira Formation of Rondônia, after which the species is named. Characteristics This species was originally described by Elizete Celestino Holanda, Ana Maria Ribeiro, and Jorge Ferigolo, in 2011, using materials from the Upper Pleistocene of the Madeira River Formation, in Araras, Nova Mamoré municipality, Rondonia state, Brazil. The type specimen of ''Tapirus rondoniensis'' is an almost complete skull with a unique combination of characteristics that differ from those of current and fossil species of ''Tapirus'' described in South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent.

Tapirus Terrestris
The South American tapir (''Tapirus terrestris''), also commonly called the Brazilian tapir (from the Tupi ''tapi'ira''), the Amazonian tapir, the maned tapir, the lowland tapir, the ''anta'' (Portuguese), and ''la sachavaca'' (literally "bushcow", in mixed Quechua and Spanish), is one of the four recognized species in the tapir family (of the order '' Perissodactyla'', with the mountain tapir, the Malayan tapir, and the Baird's tapir). It is the largest surviving native terrestrial mammal in the Amazon. Most classification taxons also include ''Tapirus kabomani'' (also known as the little black tapir or kabomani tapir) as also belonging to the species ''Tapirus terrestris'' (Brazilian tapir), despite its questionable existence and the overall lack of information on its habits and distribution. The specific epithet derives from ''arabo kabomani'', the word for tapir in the local Paumarí language. The formal description of this tapir did not suggest a common name for the species. ...

Tapirus Haysii
''Tapirus haysii'', commonly known as Cope's tapir, is an extinct species of tapir that inhabited North America during the early to middle Pleistocene Epoch (~2.5–1 Ma). The fossil remains of two juvenile ''T. haysii'' were collected in Hillsborough County, Florida on August 31, 1963. It was the second largest North American tapir; the first being '' T. merriami''. Taxonomy ''Taprirus haysii'' is placed in the subgenus ''Helicotapirus'', which also includes ''Tapirus veroensis'' and ''Tapirus lundeliusi ''Tapirus lundeliusi'' is an extinct species of tapir that lived in Florida in the early Pleistocene.

Tapirus Indicus
The Malayan tapir (''Tapirus indicus''), also called Asian tapir, Asiatic tapir and Indian tapir, is the only tapir species native to Southeast Asia from the Malay Peninsula to Sumatra. It has been listed as Endangered on the IUCN Red List since 2008, as the population is estimated to comprise fewer than 2,500 mature individuals. Taxonomy The scientific name ''Tapirus indicus'' was proposed by Anselme Gaëtan Desmarest in 1819 who referred to a tapir described by Pierre-Médard Diard. ''Tapirus indicus brevetianus'' was coined by a Dutch zoologist in 1926 who described a black Malayan tapir from Sumatra that had been sent to Rotterdam Zoo in the early 1920s. Phylogenetic analyses of 13 Malayan tapirs showed that the species is monophyletic. It was placed in the genus ''Acrocodia'' by Colin Groves and Peter Grubb in 2011. However, a comparison of mitochondrial DNA of 16 perissodactyl species revealed that the Malayan tapir forms a sister group together with the ''Tapirus ...

Tapirus
''Tapirus'' is a genus of tapir which contains the three living American tapir species. The Malayan tapir is usually included in ''Tapirus'' as well, although some authorities have moved it into its own genus, ''Acrocodia''. Extant species The Kabomani tapir was at one point recognized as another living member of the genus, but is now considered to be nested within ''T. terrestris''. Evolution ''Tapirus'' first appeared in the Late Miocene in North America, with ''Tapirus webbi'' perhaps the oldest known fossil species. ''Tapirus'' spread into South America and Eurasia during the Pliocene. It has been suggested that the tapirs that inhabited North America during the Late Pleistocene may be derived from a South American species that remigrated north, perhaps ''Tapirus cristatellus''. Tapirs suffered large-scale extinctions at the end of the Pleistocene, and went completely extinct north of southern Mexico. Fossil species *†''Tapirus arvernensis'' Croizet & Jobert, 1828 *† ...

Zygomatic Process
The zygomatic processes are three processes (protrusions) from other bones of the skull which each articulate with the zygomatic bone. The three processes are: * Zygomatic process of frontal bone from the frontal bone * Zygomatic process of maxilla from the maxilla (malar process) * Zygomatic process of temporal bone from the temporal bone The term ''zygomatic'' derives from the Greek ''Ζυγόμα'', ''zygoma'', meaning "yoke". The zygomatic process is occasionally referred to as the zygoma, but this term usually refers to the zygomatic bone or occasionally the zygomatic arch. Zygomatic process of frontal bone The supraorbital margin of the frontal bone ends laterally in its zygomatic process, which is strong and prominent, and articulates with the zygomatic bone. The zygomatic process of the frontal bone extends from the frontal bone laterally and inferiorly. Zygomatic process of maxilla The zygomatic process of the maxilla [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 said they ...

Canine Tooth
In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, or (in the context of the upper jaw) fangs, eye teeth, vampire teeth, or vampire fangs, are the relatively long, pointed teeth. They can appear more flattened however, causing them to resemble incisors and leading them to be called ''incisiform''. They developed and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in a mammal's mouth. Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. The four canines in humans are the two maxillary canines and the two mandibular canines. Details There are generally four canine teeth: two in the upper (maxillary) and two in the lower (mandibular) arch. A canine is placed laterally to ...
