Myocastor Obesus
''Myocastor'' is a genus of rodent that contains the living nutria (or coypu), as well as several fossil species. Taxonomy Due to similar cranial morphology, the nutria was once considered a close relative of the Caribbean hutias and placed together with them in the family Capromyidae. Later, it was more accepted to place it in its own family, the Myocastoridae. Recent molecular studies place them in the family Echimyidae, in the tribe Myocastorini. Fossil record Kerber et al.

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally, chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 to 8 million years ago, that is, during the Late Miocene.

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Nutria
The nutria (''Myocastor coypus''), also known as the coypu, is a large, herbivorous, semiaquatic rodent. Classified for a long time as the only member of the family Myocastoridae, ''Myocastor'' is now included within Echimyidae, the family of the spiny rats. The nutria lives in burrows alongside stretches of water, and feeds on river plant stems. Originally native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur farmers. Although it is still hunted and trapped for its fur in some regions, its destructive burrowing and feeding habits often bring it into conflict with humans, and it is considered an invasive species. Nutria also transmit various diseases to humans and animals mainly through water contamination. Etymology The genus name ''Myocastor'' derives from the two Ancient Greek words (), meaning "rat, mouse", and (), meaning "beaver". Literally, therefore, the name ''Myocastor'' means ...

Robert Kerr (writer)
Dr Robert Kerr FRSE FAS FRCSE (20 October 1757 – 11 October 1813) was a Scottish surgeon, writer on scientific and other subjects, and translator. Life Kerr was born in 1757 in Bughtridge, Roxburghshire, the son of James Kerr, a jeweller, who served as MP for Edinburgh 1747–1754, and his wife Elizabeth. He was sent to the High School in Edinburgh. He studied medicine at the University of Edinburgh and practised at the Edinburgh Foundling Hospital as a surgeon. He was elected a Fellow of the Royal Society of Edinburgh in 1788. His proposers were Alexander Fraser Tytler, James Russell and Andrew Dalzell. At this time he lived at Foresters Wynd off the Royal Mile in Edinburgh. He translated several scientific works into English, such as Antoine Lavoisier's work of 1789, ''Traité Élémentaire de Chimie'', published under the title ''Elements of Chemistry in a New Systematic Order containing All the Modern Discoveries'', in 1790. In 1792, he published ''The Animal Kingdom' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hutias
Hutias (known in Spanish as jutía) are moderately large cavy-like rodents of the subfamily Capromyinae that inhabit the Caribbean islands, with most species restricted to Cuba and Hispaniola. Twenty species of hutia have been identified, but at least half are extinct. Only Desmarest's hutia and the prehensile-tailed hutia remain common and widespread; all other extant species are considered threatened by the IUCN. The extinct giant hutias of the family Heptaxodontidae also inhabited the Caribbean, but are not thought to be closely related, with the giant hutias belonging in the superfamily Chinchilloidea. Description Most species have a head-and-body length that ranges from and weigh less than , but Desmarest's hutia has a head-and-body length of and weighs . They resemble the coypu in some respects. Tails are present, varying from vestiges to prehensile. They have stout bodies and large heads. Most species are herbivorous, though some consume small animals. Instead of burro ...

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] |
