Etayoa Trypethelii
''Etayoa'' is an ungulate of the family Carodniidae in the order Xenungulata that lived during the Early Eocene (~ 55 Ma) in northern South America. Etymology The genus of the type species ''Etayoa bacatensis'' was named by palaeontologist Carlos Villarroel after Fernando Etayo Serna, who contributed extensively to the paleontology and stratigraphy research in Colombia. The species epithet ''bacatensis'' refers to Bacatá,Villarroel, 1987 the name in Muysccubun for the main settlement of the southern Muisca Confederation; the name of which has been used for the current Colombian capital Bogotá, founded in a different location than the original Bacatá.

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Paleocene–Eocene Thermal Maximum
The Paleocene–Eocene thermal maximum (PETM), alternatively ”Eocene thermal maximum 1 (ETM1)“ and formerly known as the "Initial Eocene" or “Late Paleocene thermal maximum", was a geologically brief time interval characterized by a global average temperature rise and massive input of carbon into the ocean and atmosphere. The event began, now formally codified, at the precise time boundary between the Paleocene and Eocene geological Epoch (geology), epochs. The exact age and duration of the PETM remain uncertain, but it occurred around 55.8 million years ago (Ma) and lasted about 200 thousand years (Ka). The PETM arguably represents our best past analogue for which to understand how global warming and the carbon cycle operate in a greenhouse world. The time interval is marked by a prominent negative excursion in carbon stable isotope () records from around the globe; more specifically, a large decrease in the 13C/Carbon-12, 12C ratio of marine and terrestrial carbon ...

Paleosol
In Earth science, geoscience, paleosol (''palaeosol'' in Great Britain and Australia) is an ancient soil that formed in the past. The definition of the term in geology and paleontology is slightly different from its use in soil science. In geology and paleontology, a paleosol is a former soil preserved by burial underneath either sediments (alluvium or loess) or volcanic deposits (lava flows or volcanic ash), which in the case of older deposits have Lithification, lithified into Rock (geology), rock. In Quaternary geology, sedimentology, paleoclimatology, and geology in general, it is the typical and accepted practice to use the term "paleosol" to designate such "''fossil soils''" found buried within sedimentary and volcanic deposits exposed in all continents. In soil science the definition differs slightly: paleosols are soils formed long ago that have no relationship in their chemical and physical characteristics to the present-day climate or vegetation. Such soils are found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Eocene Climatic Optimum
The Early Eocene Climatic Optimum (EECO), also referred to as the Early Eocene Thermal Maximum (EETM), was a period of extremely warm greenhouse climatic conditions during the Eocene epoch. The EECO represented the hottest sustained interval of the Cenozoic era and one of the hottest periods in all of Earth's history. Duration The EECO lasted from about 54 to 49 Ma. The EECO's onset is signified by a major geochemical enrichment in isotopically light carbon, commonly known as a negative ''δ''13C excursion, that demarcates the hyperthermal Eocene Thermal Maximum 3 (ETM3). Climate Following some climate models, the EECO was marked by an extremely high global mean surface temperature, which has been estimated to be anywhere between 23.2 and 29.7 °C, with the mean estimate being around 27.0 °C. In North America, the mean annual temperature was 23.0 °C, while the continent's overall mean annual precipitation (MAP) was about 1500 mm. The mean annual temperature range (MATR) o ...

Paleobiology Database
The Paleobiology Database (PBDB) is an online resource for information on the distribution and classification of fossil animals, plants, and microorganisms. History The Paleobiology Database originated in the NCEAS-funded Phanerozoic Marine Paleofaunal Database initiative, which operated from August 1998 through August 2000. From 2000 to 2015, PBDB received funding from the National Science Foundation. PBDB also received support form the Australian Research Council. From 2000 to 2010 it was housed at the National Center for Ecological Analysis and Synthesis, a cross-disciplinary research center within the University of California, Santa Barbara. It is currently housed at University of Wisconsin-Madison and overseen by an international committee of major data contributors. The Paleobiology Database works closely with the Neotoma Paleoecology Database, which has a similar intellectual history, but has focused on the Quaternary (with an emphasis on the late Pleistocene and Holoc ...

Ciudad Bolívar (Bogotá)
Ciudad Bolívar (; Spanish for "Bolivar City"), formerly known as Angostura and St. Thomas de Guyana, is the capital of Venezuela's southeastern Bolívar, Venezuela, Bolívar State. It lies at the spot where the Orinoco River narrows to about in width, is the site of the first bridge across the river, and is a major riverport for the eastern regions of Venezuela. Historic Angostura gave its name to the Congress of Angostura, to the Cusparia febrifuga, Angostura tree, to the House of Angostura, and to Angostura bitters. Modern Ciudad Bolívar has a well-preserved historic center; a cathedral and other original colonial buildings surround the Plaza Bolívar. History Originally a Spanish settlement, it was called ''Santo Tomé de Guayana'' (Saint Thomas of Guyana). The settlement was a fortified port which had to be moved on three occasions because it was constantly attacked by Kalina people, Carib natives and European rivals, such as the Dutch and English. In 1576 ''Saint Thom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
