Córdoba, Argentina
Córdoba () is a city in central Argentina, in the foothills of the Punilla Valley, Sierras Chicas on the Primero River, Suquía River, about northwest of Buenos Aires. It is the capital of Córdoba Province, Argentina, Córdoba Province and the List of cities in Argentina by population, second-most populous city in Argentina after Buenos Aires, with about 1.6 million urban inhabitants . Córdoba was founded as a settlement on 6 July 1573 by Spanish Empire, Spanish conquistador Jerónimo Luis de Cabrera, who named it after the Spanish city of Córdoba, Spain, Córdoba. It was one of the early Spanish colonial capitals of the region of present-day Argentina (the oldest Argentine city is Santiago del Estero, founded in 1553). The National University of Córdoba, the oldest university of the country, was founded in 1613 by the Society of Jesus, Jesuit Order, and Córdoba has earned the nickname ("the learned"). Córdoba has many historical monuments preserved from the period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleontologist
Paleontology, also spelled as palaeontology or palæontology, is the scientific study of the life of the past, mainly but not exclusively through the study of fossils. Paleontologists use fossils as a means to classify organisms, measure geologic time, and assess the interactions between prehistoric organisms and their natural environment. While paleontological observations are known from at least the 6th century BC, the foundation of paleontology as a science dates back to the work of Georges Cuvier in 1796. Cuvier demonstrated evidence for the concept of extinction and how life of the past was not necessarily the same as that of the present. The field developed rapidly over the course of the following decades, and the French word ''paléontologie'' was introduced for the study in 1822, which was derived from the Ancient Greek word for "ancient" and words describing relatedness and a field of study. Further advances in the field accompanied the work of Charles Darwin who popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanosauria
Titanosaurs (or titanosaurians; members of the group Titanosauria) were a diverse group of Sauropoda, sauropod dinosaurs, including genera from all seven continents. The titanosaurs were the last surviving group of long-necked sauropods, with taxa still thriving at the time of the Cretaceous–Paleogene extinction event, extinction event at the end of the Cretaceous. This group includes some of the Largest land animal, largest land animals known to have ever existed, such as ''Patagotitan'', estimated at long with a mass of , and the comparably-sized ''Argentinosaurus'' and ''Puertasaurus'' from the Patagonia, same region. The group's name alludes to the mythological Titan (mythology), Titans of ancient Greek mythology, via the type genus (now considered a ''nomen dubium)'' ''Titanosaurus''. Together with the Brachiosauridae, brachiosaurids and relatives, titanosaurs make up the larger sauropod clade Titanosauriformes. Titanosaurs have long been a poorly-known group, and the rela ...

Aeolosaurus Rionegrinus
''Aeolosaurus'' (; "Aeolus' lizard") is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now South America. Like most sauropods, it would have been a quadrupedal herbivore with a long neck and tail. ''Aeolosaurus'' is well known for a titanosaur, as it is represented by the remains of several individuals belonging to at least two species. However, like most titanosaurs, no remains of the skull are known. The holotype of ''Aeolosaurus rionegrinus'' consists of a series of seven tail vertebrae, as well as parts of both forelimbs and the right hindlimb. It was discovered in the Angostura Colorada Formation in Argentina, which dates from the Campanian stage of the Late Cretaceous, about 83 to 74 million years ago. The species ''A. maximus'' was transferred over to the new genus '' Arrudatitan'' in 2021. Etymology This dinosaur is named after the Greek mythological figure Aeolus, Keeper of the Winds in Homer's Odyssey, because of the frequent winds ...

Unquillosaurus
''Unquillosaurus'' (meaning "Unquillo river lizard") is a genus of large theropod dinosaur from the Late Cretaceous Los Blanquitos Formation of Salta Province, Argentina. Its precise classification is uncertain, but most researchers consider it as a maniraptoran. The genus contains a single species, ''U. ceibalii'', known only from a single fossilized pubis (a pelvic bone). Discovery and naming The holotype, PVL 3670-11, was found at Arroyo-Morterito in the Los Blanquitos Formation, dating to the Maastrichtian. The specimen, which consists of a left pubis measuring long, was re-studied by Fernando Novas and Federico Agnolin in 2004, who concluded that the orientation of the pubis had been misinterpreted: it pointed backwards, as was shown by the fossil still being attached to a displaced part of the pubic peduncle of the ilium. The type species ''Unquillosaurus ceibalii'' was described by Jaime Eduardo Powell in 1979. The generic name, "''Unquillosaurus''," is derived ...

Argentine Paleontologists
Argentines, Argentinians or Argentineans are people from Argentina. This connection may be residential, legal, historical, or cultural. For most Argentines, several (or all) of these connections exist and are collectively the source of their being Argentine. Argentina is a multiethnic society, home to people of various ethnic, racial, religious, denomination, and national origins, with the majority of the population made up of Old World immigrants and their descendants. As a result, Argentines do not equate their nationality with ethnicity, but with citizenship and allegiance to Argentina. Aside from the indigenous population, nearly all Argentines or their ancestors immigrated within the past five centuries. Among countries in the world that have received the most immigrants in modern history, Argentina, with 6.6 million, ranks second to the United States (27 million), and ahead of other immigrant destinations such as Canada, Brazil and Australia.
