Oreamnos
''Oreamnos'' is a genus of North American caprines. The mountain goat (''Oreamnos americanus'') is the only living species. Until the end of the Pleistocene The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.

Mountain Goat
The mountain goat (''Oreamnos americanus''), also known as the Rocky Mountain goat, is a hoofed mammal endemic to mountainous areas of western North America. A subalpine to alpine species, it is a sure-footed climber commonly seen on cliffs and ice. Despite its vernacular name and both genera being in the same subfamily (Caprinae), the mountain goat is not a member of ''Capra'', the genus that includes all other goats, such as the wild goat (''Capra aegagrus''), from which the domestic goat is derived. Instead, it is more closely allied with the takins (''Budorcas'') and chamois (''Rupicapra''). Classification and evolution The mountain goat is an even-toed ungulate of the order Artiodactyla and the family Bovidae (along with antelopes, gazelles, and cattle). It belongs to the subfamily Caprinae, along with true goats, wild sheep, the chamois, the muskox and other species. The takins of the Himalayan region, while not a sister lineage of the mountain goat, are nonetheless ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Harrington's Mountain Goat
Harrington's mountain goat (''Oreamnos harringtoni'') was a species of North American Goat-antelope, caprine that resided in the Southwest of the continent during the Pleistocene epoch. A relative of the modern mountain goat, which is the only existing species in the genus ''Oreamnos'', ''O. harringtoni'' became extinct around 11,000 B.C. Fossil record Harrington's mountain goat was first described in the 1930s by paleontologist Chester Stock. Stock based his initial description on finds of skull fragments and metapodial bones from Smith Creek Cave in the Great Basin of Nevada. In 1937 he authored a ''Bulletin of the Southern California Academy of Sciences'' article titled "A new mountain goat from the Quaternary of Smith Creek Cave, Nevada". Later finds in Mexico, Colorado, Nevada, Utah, New Mexico, and the Grand Canyon have included intact skulls, metapodials, keratinous horn sheaths, dung, hair, muscle and ligament. Characteristics Harrington's mountain goat was smaller than ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Caprinae
The subfamily Caprinae, also sometimes referred to as the tribe Caprini, is part of the ruminant family Bovidae, and consists of mostly medium-sized bovids. A member of this subfamily is called a caprine, or, more informally, a goat-antelope (although they are not considered antelopes). Within this tribe, a prominent clade includes sheep and goats. Some earlier taxonomies considered Caprinae a separate family called Capridae (with the members being caprids), but now it is usually considered either a subfamily within the Bovidae, or a tribe within the subfamily Antilopinae of the family Bovidae, with caprines being a type of bovid. Characteristics Although most goat-antelopes are gregarious and have fairly stocky builds, they diverge in many other ways – the muskox (''Ovibos moschatus'') is adapted to the extreme cold of the tundra; the mountain goat (''Oreamnos americanus'') of North America is specialised for very rugged terrain; the urial (''Ovis orientalis'') occup ...

Mammal Genera
There are currently 1,258 genera, 156 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being ''Handbook of the Mammals of the World'' series and ''Mammal Species of the World''.

Constantine Samuel Rafinesque-Schmaltz
Constantine Samuel Rafinesque-Schmaltz (; October 22, 1783September 18, 1840) was a French 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of Mound builder (people), prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican languages, Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and Polyglot (person), polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community whose submissions were reject ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

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 ...

Mammal Genera With One Living Species
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...
