Mesomys Hispidus
''Mesomys'' is a genus of South American spiny rats in the family Echimyidae. The genus name ''Mesomys'' derives from the two ancient greek words (), meaning "middle of, between", and (), meaning "mouse, rat". It refers to the fact that this rodent — literally the "middle mouse" — has been considered as an intermediate form related both to mice and jumping rats. Extant Species Phylogeny ''Mesomys'' is a member of the Echimyini clade of arboreal Arboreal locomotion is the locomotion of animals in trees.

Johann Andreas Wagner
Johann Andreas Wagner (21 March 1797 – 17 December 1861) was a German palaeontologist, zoologist and archaeologist who wrote several important works on palaeontology. Career Wagner was a professor at the University of Munich, and curator of the Zoologische Staatssammlung (State Zoology Collection). He was the author of ''Die Geographische Verbreitung der Säugethiere Dargestellt'' (1844–46). Wagner was a Christian creationist. Pikermi In his travels to the fossil beds of Pikermi, Wagner discovered and described fossil remains of mastodon, '' Dinotherium'', ''Hipparion ''Hipparion'' (Greek, "pony") is an extinct genus of horse that lived in North America, Asia, Europe, and Africa during the Miocene through Pleistocene ~23 Mya—781,000 years ago.

Mesomys Leniceps
The woolly-headed spiny tree-rat (''Mesomys leniceps'') is a species of rodent in the family Echimyidae. It is endemic to Peru. The etymology of the species name corresponds to the Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages.

South American
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. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Panama ...

Echimyidae
Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. They presently exist mainly in South America; three members of the family also range into Central America, and the hutias are found in the Greater Antilles in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles, probably until the arrival of Europeans. Characteristics In general form, most spiny rats resemble rats, although they are more closely related to guinea pigs and chinchillas. Most species have stiff, pointed hairs, or spines, that presumably serve for protection from predators. Many echimyids can break off their tails when attacked. This action may confuse predators long enough for the spiny rat to es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echimyini
Echimyini is a tribe of echimyid rodents, proposed in 2016, and containing 13 extant genera: all of the tree rats ''Echimys'', ''Phyllomys'', '' Makalata'', ''Pattonomys'', '' Toromys'', ''Diplomys'', ''Santamartamys'', and ''Isothrix'', the long recognized dactylomines ''Dactylomys'', ''Olallamys'', and '' Kannabateomys'', and the enigmatic and previously classified as eumysopines '' Lonchothrix'' and ''Mesomys''. All these spiny rats genera are arboreal. Worth of note, the arboreal genus ''Callistomys'' – the painted-tree rat – does not belong to the tribe Echimyini. Because it is phylogenetically closer to ''Myocastor'', ''Hoplomys'', ''Proechimys'', and ''Thrichomys'' than to the above-mentioned Echimyini genera, it is classified in the tribe Myocastorini. Phylogeny Five assemblages can be distinguished in the genus-level cladogram of Echimyini: * ''Echimys'' is closely related to ''Phyllomys'', ''Makalata'', ''Pattonomys'' and ''Toromys''. This clade is in accordance w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arboreal
Arboreal locomotion is the Animal locomotion, locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on n ...
