Cocatherium
''Cocatherium'' is an extinct genus of marsupial mammals of uncertain family placement, from the earliest Paleocene (Danian, early Danian) of South America, predating the Tiupampan South American land mammal age. The genus was described based on a fossil Molar (tooth), molar that was found in the Danian part of the Cretaceous-Paleogene boundary, Cretaceous-Paleogene Lefipán Formation in the Cañadón Asfalto Basin in north-central Patagonia, Argentina. The type species of the genus is ''C. lefipanum''.''Cocatherium'' at Fossilworks.org The mammal, probably belonging to the Polydolopimorphia, is the oldest known representative of marsupials or any therian mammal in the Southern Hemisphere. Etymology The genus was named ''Cocatherium'' ("Coca Beast") after "Coca", the ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lefipán Formation
The Lefipán Formation is a Maastrichtian to Danian, straddling the Cretaceous-Paleogene boundary, geologic formation of the Cañadón Asfalto Basin in Chubut Province, Patagonia, Argentina. The up to thick stratigraphic unit comprises mudstones, sandstones, siltstones and conglomerates, sourced from the North Patagonian Massif and deposited in a deltaic to shallow marine environment with a strong tidal influence. The basin that in those times was connected to the widening South Atlantic Ocean with a seaway connection to the Austral Basin and possibly with the Pacific Ocean. The formation has provided unique fossil flora assemblages dating to the Cretaceous and Paleogene ages, and are characteristic of the early Cenozoic after the extinction of the dinosaurs. The occurrence of the same taxa in the Maastrichtian and Danian successions suggests that the Cretaceous-Paleogene extinction event did not affect aquatic plant communities, which retained approximately similar structure a ...

Cañadón Asfalto Basin
The Cañadón Asfalto Basin ( es, Cuenca de Cañadón Asfalto) is an irregularly shaped sedimentary basin located in north-central Patagonia, Argentina. The basin stretches from and partly covers the North Patagonian Massif in the north, a high forming the boundary of the basin with the Neuquén Basin in the northwest, to the Cotricó High in the south, separating the basin from the Golfo San Jorge Basin. It is located in the southern part of Río Negro Province and northern part of Chubut Province. The eastern boundary of the basin is the North Patagonian Massif separating it from the offshore Valdés Basin and it is bound in the west by the Patagonian Andes, separating it from the small Ñirihuau Basin. The basin started forming in the Early Jurassic, with the break-up of Pangea and the creation of the South Atlantic, when extensional tectonics, including rifting, formed several basins in eastern South America and southwestern Africa. The accommodation space in the Cañadón Asf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mapuche People
The Mapuche ( (Mapuche & Spanish: )) are a group of indigenous inhabitants of south-central Chile and southwestern Argentina, including parts of Patagonia. The collective term refers to a wide-ranging ethnicity composed of various groups who shared a common social, religious, and economic structure, as well as a common linguistic heritage as Mapudungun speakers. Their habitat once extended from Aconcagua Valley to Chiloé Archipelago and later spread eastward to Puelmapu, a land comprising part of the Argentine pampa and Patagonia. Today the collective group makes up over 80% of the indigenous peoples in Chile, and about 9% of the total Chilean population. The Mapuche are particularly concentrated in the Araucanía region. Many have migrated from rural areas to the cities of Santiago and Buenos Aires for economic opportunities. The Mapuche traditional economy is based on agriculture; their traditional social organization consists of extended families, under the direction of a ...

Epithet
An epithet (, ), also byname, is a descriptive term (word or phrase) known for accompanying or occurring in place of a name and having entered common usage. It has various shades of meaning when applied to seemingly real or fictitious people, divinities, objects, and binomial nomenclature. It can also be a descriptive title: for example, Pallas Athena, Phoebus Apollo, Alfred the Great, Suleiman the Magnificent, and Władysław I the Elbow-high. Many English monarchs have traditional epithets: some of the best known are Edward the Confessor, William the Conqueror, Richard the Lionheart, Æthelred the Unready, John Lackland and Bloody Mary. The word ''epithet'' can also refer to an abusive, defamatory, or derogatory phrase. This use as a euphemism is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler complained that "epithet is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are sometimes at ...

Museo De La Plata
The La Plata Museum ( es, Museo de la Plata) is a natural history museum in La Plata, Argentina. It is part of the (Natural Sciences School) of the UNLP (National University of La Plata). The building, long, today houses 3 million fossils and relics (including 44,000 botanical items), an amphitheatre, opened in 1992, and a 58,000-volume library, serving over 400 university researchers. Around 400,000 visitors (8% of whom are from outside Argentina) pass through its doors yearly, including a thousand visiting researchers. History Childhood excursions with his father and older brother led the 14-year-old Francisco Moreno to mount a display of his growing collection of anthropological, fossil and bone findings at his family's Buenos Aires home in 1866, unwittingly laying the foundations for the future La Plata Museum. Moreno spent the time between 1873 and 1877 exploring his country's then-remote and largely unmapped Patagonia, becoming the first non-indigenous Argentine to re ...

Fossilworks
Fossilworks is a portal which provides query, download, and analysis tools to facilitate access to the Paleobiology Database The Paleobiology Database is an online resource for information on the distribution and classification of fossil animals, plants, and microorganisms. History The Paleobiology Database (PBDB) originated in the NCEAS-funded Phanerozoic Marine Pale ..., a large relational database assembled by hundreds of paleontologists from around the world. History Fossilworks was created in 1998 by John Alroy and is housed at Macquarie University. It includes many analysis and data visualization tools formerly included in the Paleobiology Database.{{cite web, title=Frequently asked questions, url=http://www.fossilworks.org/cgi-bin/bridge.pl?page=FAQ, publisher=Fossilworks, access-date=17 December 2021 References {{Reflist External links {{Wikidata property, P842 * [Baidu] |
