The western mountain coati or western dwarf coati (Nasuella olivacea) is a small procyonid, found in cloud forest and páramo at altitudes of 1,300–4,250 metres (4,270–13,940 ft) in the Andes of Colombia and Ecuador. A population discovered in the Apurímac–Cuzco region of southern Peru (more than 1,000 km or 620 mi south of the previous distribution limit) has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.
Until 2009, the western mountain coati (then simply known as the mountain coati) usually included the eastern mountain coati as a subspecies, but that species is overall smaller, somewhat shorter-tailed on average, has markedly smaller teeth, a paler olive-brown pelage, and usually a dark mid-dorsal stripe on the back (versus more rufescent or blackish, and usually without a dark mid-dorsal stripe in the western mountain coati). When the two were combined, they were rated as Data Deficient by the IUCN, but following the split the western mountain coati is considered Near Threatened.
There are two subspecies of the western mountain coati: N. o. olivacea and the slightly smaller and darker N. o. quitensis with less distinct rings on the tail. The former is known from Colombia and the latter from Ecuador, but the exact distribution limit between the two is not known.

Aguazuque is a pre-Columbian archaeological site located in the western part of the municipality Soacha, close to the municipalities Mosquera and San Antonio del Tequendama in Cundinamarca, Colombia. It exists of evidences of human settlement of hunter-gatherers and in the ultimate phase primitive farmers. The site is situated on the Bogotá savanna, the relatively flat highland of the Altiplano Cundiboyacense close to the present-day course of the Bogotá River at an altitude of 2,600 metres (8,500 ft) above sea level. Aguazuque is just north of another Andean preceramic archaeological site; the rock shelter Tequendama and a few kilometres south of Lake Herrera. The artefacts found mostly belong to the preceramic period, and have been dated to 5025 to 2725 BP (3000 to 700 BCE). Thus, the younger finds also pertain to the later ceramic Herrera Period. There were some difficulties in dating of the uppermost layer due to modern agricultural activity in the area; the sediments of the shallower parts were disturbed.
At Aguazuque multiple palaeoantropological finds have been made; stone and bone tools, remains of fireplaces and a multitude of pre-Columbian foods, primitive circular housing, various burial sites of individual and group interments and in the youngest dated layers, evidences of ceramics.
The site represents a transition from a hunter-gatherer culture towards the earliest evidence of agriculture. A phase of settlement is attested where the people moved away from the caves and rock shelters and started inhabiting open area grounds.
Investigation of Aguazuque has been conducted since 1986, mainly by archaeologist Gonzalo Correal Urrego who published the results of his studies in the book Aguazuque - evidencias de cazadores, recolectores y plantadores en la altiplanicie de la Cordillera Oriental in 1990.Altiplano Cundiboyacense
The Altiplano Cundiboyacense [altiˈplano kundiβoʝaˈsense] is a high plateau located in the Eastern Cordillera of the Colombian Andes covering parts of the departments of Cundinamarca and Boyacá. The altiplano corresponds to the ancient territory of the Muisca. The Altiplano Cundiboyacense comprises three distinctive flat regions; the Bogotá savanna, the valleys of Ubaté and Chiquinquirá, and the valleys of Duitama and Sogamoso. The average altitude of the altiplano is about 2,600 metres (8,500 ft) above sea level but ranges from roughly 2,500 metres (8,200 ft) to 4,000 metres (13,000 ft).Coati
Coatis, also known as the coatimundis (), are members of the raccoon family (Procyonidae) in the genera Nasua and Nasuella. They are diurnal mammals native to South America, Central America, and southwestern North America. The name coatimundi is purportedly derived from the Tupian languages of Brazil.The coati is also known in English as the hog-nosed coon.Dwarf coati
Dwarf coati can refer to several species:
Cozumel Island coati (Nasua narica nelsoni) – from Cozumel Island, Mexico.
Eastern mountain coati (Nasuella meridensis) – from the Andes in Venezuela.
Western mountain coati (Nasuella olivacea) – from the Andes in Colombia and Ecuador.List of flora and fauna of the Eastern Hills, Bogotá
The Eastern Hills of Bogotá is a threatened but rich area of biodiversity. Various species have been registered in the Eastern Hills of the Colombian capital.List of mammals of South America
This is a list of the native wild mammal species recorded in South America. South America's terrestrial mammals fall into three distinct groups: 'old-timers', African immigrants and recent North American immigrants. The marsupials and xenarthrans are 'old-timers', their ancestors having been present on the continent since at least the very early Cenozoic Era. During the early Cenozoic, South America's only land connection was to Antarctica, so it was effectively cut off from most of the world; as the fragments of Gondwana continued to separate, this connection was lost, leaving South America an island continent. Caviomorph rodents and monkeys arrived as 'waif dispersers' by rafting across the Atlantic from Africa in the Eocene epoch, 35 million or more years ago. All the remaining nonflying mammals of South America are recent arrivals, having migrated from North America via Central America during the past seven million years as part of the Great American Interchange; this invasion, which peaked around three million years ago, was made possible when the formation of the volcanic Isthmus of Panama bridged North and South America. The newcomers out-competed and drove to extinction many unique mammals that had evolved during South America's long period of isolation, as well as some species from other classes (e.g., terror birds).South America suffered another major loss of mammal species in the Quaternary extinction event, which started around 12500 cal BP, at roughly the time of arrival of Paleoindians, and may have lasted up to several thousand years. At least 37 genera of mammals were eliminated, including most of the megafauna. While South America currently has no megaherbivore species weighing more than 1000 kg, prior to this event it had a menagerie of about 25 of them (consisting of gomphotheres, camelids, ground sloths, glyptodonts, and toxodontids – 75% of these being 'old-timers'), dwarfing Africa's present and recent total of 6.Anthropogenic climate change and the damage to its ecosystems resulting from the rapid recent growth of the human population pose a further threat to South America's biodiversity.
The list consists of those species found in the nations or overseas territories of continental South America (including their island possessions, such as the Galápagos), as well as in Trinidad and Tobago and the Falkland Islands; Panama is not included. As of May 2012, the list contains 1331 species, 340 genera, 62 families and 15 orders. Of the taxa from nonflying, nonmarine groups (992 species, 230 genera, 40 families and 12 orders), 'old-timers' comprise 14% of species, 15% of genera, 20% of families and 42% of orders; African immigrants make up 38% of species, 30% of genera, 40% of families and 17% of orders; North American invaders constitute 49% of species 55% of genera, 40% of families and 50% of orders. At the order level, the 'old-timers' are overrepresented because of their ancient local origins, while the African immigrants are underrepresented because of their 'sweepstakes' mode of dispersal.
Of the species, 9 are extinct, 29 are critically endangered, 64 are endangered, 111 are vulnerable, 64 are near-threatened, and 255 are data-deficient. Mammal species presumed extinct since AD 1500 (nine or ten cases) are included. Domestic species (e.g., the guinea pig, alpaca, and llama) and introduced species are not listed.
NOTE: this list is inevitably going to be incomplete, since new species are continually being recognized via discovery or reclassification. Places to check for missing species include the Wikipedia missing mammal species list, including recently removed entries, and the species listings in the articles for mammalian genera, especially those of small mammals such as rodents or bats.
The following tags are used to highlight each species' conservation status as assessed by the IUCN; those on the left are used here, those in the second column in some other articles:
The IUCN status of all listed species except bats was last updated during the period from March to June 2009; bats were updated in September 2009.Nasua
Nasua is a genus of coatis of the family Procyonidae. Two additional species of coatis, commonly known as mountain coatis, are placed in the genus Nasuella.Nasuella
Mountain coatis are two species of procyonid mammals from the genus Nasuella. Unlike the larger coatis from the genus Nasua, mountain coatis only weigh 1.0–1.5 kilograms (2.2–3.3 lb) and are endemic to the north Andean highlands in South America.Procyonidae
Procyonidae is a New World family of the order Carnivora. It comprises the raccoons, coatis, kinkajous, olingos, olinguitos, ringtails, and cacomistles. Procyonids inhabit a wide range of environments and are generally omnivorous.
