Mayulestes
''Mayulestes'' (Quechua: ''mayu'' river, + Greek: ''lestes'', thief) is a genus of carnivorous metatherian that lived in what is now Tiupampa, Bolivia in the early Paleocene. It shared its habitat with fellow sparrasodont ''Pucadelphys'', and a microbiotherid marsupial, ''Khasia ''Khasia'' ("from Antin Khasa") is a fossil genus of marsupial in the family Microbiotheriidae.

Sparassodonts
Sparassodonta (from Greek to tear, rend; and , gen. , ' tooth) is an extinct order of carnivorous metatherian mammals native to South America, related to modern marsupials. They were once considered to be true marsupials, but are now thought to be a separate side branch that split before the last common ancestor of all modern marsupials. A number of these mammalian predators closely resemble placental predators that evolved separately on other continents, and are cited frequently as examples of convergent evolution. They were first described by Florentino Ameghino, from fossils found in the Santa Cruz beds of Patagonia. Sparassodonts were present throughout South America's long period of "splendid isolation" during the Cenozoic; during this time, they shared the niches for large warm-blooded predators with the flightless terror birds. Previously, it was thought that these mammals died out in the face of competition from "more competitive" placental carnivorans during the Pli ...

Tiupampan
The Tiupampan ( es, Tiupampense) age is a period of geologic time (64.5–62.5 Ma) within the Paleocene epoch of the Paleogene used more specifically with South American land mammal ages (SALMA). It is the oldest SALMA age and precedes the Peligran age.Tiupampan in the Paleobiology Database

Pucadelphys
''Pucadelphys'' is an extinct genus of non-marsupial metatherian. The genus contains a single species, ''P. andinus''. Fossils of ''Pucadelphys'' have been found in the Santa Lucía Formation in Tiupampa in Bolivia.''Pucadelphys'' at .org Description ''Pucadelphys'' was small and likely to have eaten insects. It had a long tail, although incomplete on the best preserved fossils. It is possible that the tail was longer than (or at least as long as) its body. 17 vertebrae were preserved, and its estimated that there was 5 to 10 additional vertebrae originally. It is regarded as partially arboreal, and partially terrestrial. It may have been social, as mo ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Danian
The Danian is the oldest age or lowest stage of the Paleocene Epoch or Series, of the Paleogene Period or System, and of the Cenozoic Era or Erathem. The beginning of the Danian (and the end of the preceding Maastrichtian) is at the Cretaceous–Paleogene extinction event . The age ended , being followed by the Selandian. Stratigraphic definitions The Danian was introduced in scientific literature by German-Swiss geologist Pierre Jean Édouard Desor in 1847 following a study of fossils found in France and Denmark.Danien He identified this stage in deposits from |
Quechua Boliviano
South Bolivian Quechua, also known as Central Bolivian Quechua, is a dialect of Southern Quechua spoken in Bolivia and adjacent areas of Argentina, where it is also known as ''Colla''. It is not to be confused with North Bolivian Quechua, which is spoken on the northern Andean slopes of Bolivia and is phonologically distinct from the South Bolivian variety. Estimates of the number of speakers of South Bolivian Quechua range from 2.3Moseley, Christopher (ed.). 2010"Atlas of the World’s Languages in Danger, 3rd edn."Paris, UNESCO Publishing.

Microbiotheriidae
Microbiotheriidae is a family of australidelphian marsupials represented by only one extant species, the monito del monte, and a number of extinct species known from fossils in South America, Western Antarctica, and northeastern Australia. Microbiotheriids were once thought to be members of the order Didelphimorphia (which contains the Virginia opossum); however, an accumulation of both anatomical and genetic evidence in recent years has led to the conclusion that microbiotheriids and other microbiotheres are not didelphids at all, but are instead most closely related to the Australasian marsupials; together, the microbiotheres and the Australian orders form the clade Australidelphia which are now thought to have first evolved in the South American region of Gondwana. Biogeography The oldest microbiotheriid and microbiothere currently recognised is ''Khasia cordillerensis'', based on fossil teeth from Early Palaeocene deposits at Tiupampa, Bolivia. Numerous genera are known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleocene Mammals Of South America
The Paleocene, ( ) or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. In the Paleocene, the continents of the Northern Hemisphere were still connected via som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
