Baurutitan
''Baurutitan'' is a genus of sauropod dinosaur that lived during the Late Cretaceous in what is now Brazil. The type species, ''Baurutitan britoi'', was described in 2005 by Kellner and colleagues, although the fossil remains had already been discovered in 1957. ''Baurutitan'' is classified as a lithostrotian titanosaur, and is distinguished from related genera based on its distinctive caudal vertebrae. This South American dinosaur was found in the Serra da Galga Formation near Uberaba, in the Brazilian state of Minas Gerais. Discovery The holotype of ''Baurutitan'' were found in 1957 by Llewellyn Ivor Price, the famous Brazilian paleontologist, in the region of Peirópolis, Minas Gerais. However, it was not until 2005 that ''Baurutitan'' was officially published and named. The works of Price in Peirópolis began in 1947 after Jesuíno Felicíssimo Junior, from the Instituto Geográfico e Geológico of São Paulo, told him about the presence of fossils in the region. Price then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caieiria
''Caieiria'' (named after the Caieira locality where its fossils were recovered) is a genus of titanosaurian dinosaur from the Late Cretaceous Serra da Galga Formation (formerly a unit of the Marília Formation) of Brazil. The type and only species is ''Caieiria allocaudata''. Discovery and naming From the 1940s to 1960s, the paleontologist Llewellyn Ivor Price excavated several series of titanosaur fossils in the "Caieira" locality of the Serra da Galga Formation in Minas Gerais, Brazil and he discovered the holotype of ''Caieiria'' around 1957. Two of these, "Series B" or MCT 1488-R and "Series C" or MCT 1490-R, have been named the holotypes of two titanosaur genera: ''Trigonosaurus'' and ''Baurutitan'' respectively. The describers of ''Trigonosaurus'' also referred a series of ten caudal vertebrae, MCT 1719-R, as the paratype of their new genus. Further titanosaurs from the BR-262 site of the same locality were reported by Silva Junior and colleagues in 2022, and in light of th ...

Titanosaur
Titanosaurs (or titanosaurians; members of the group Titanosauria) were a diverse group of 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 extinction event at the end of the Cretaceous. This group includes some of the largest land animals known to have ever existed, such as ''Patagotitan''—estimated at long with a weight of —and the comparably-sized ''Argentinosaurus'' and ''Puertasaurus'' from the same region. The group's name alludes to the mythological Titans of ancient Greek mythology, via the type genus (now considered a '' nomen dubium)'' ''Titanosaurus''. Together with the brachiosaurids and relatives, titanosaurs make up the larger sauropod clade Titanosauriformes. Titanosaurs have long been a poorly-known group, and the relationships between titanosaur species are still not well-understood. Description Titanosauria have the largest ...

Trigonosaurus Pricei
''Trigonosaurus'' (meaning "triangle lizard" after Triangulo Mineiro, where it was found), is a genus of saltasaurid dinosaurs from the Maastrichtian Serra da Galga Formation of Brazil. The type species, ''Trigonosaurus pricei'', was first described by Campos, Kellner, Bertini, and Santucci in 2005. It was based on two specimens, both consisting mainly of vertebrae. The two specimens were believed to have come from the same individual. However, one specimen was described as the holotype of ''Caieiria'' in 2022. Before its description, it was known as the "Peirópolis titanosaur", after the place it was found. History From the 1940s to 1960s, Brazilian paleontologist Llewellyn Ivor Price excavated several series of titanosaur fossils in the "Caieira" locality of the Serra da Galga Formation in Minas Gerais, Brazil. Two of these, "Series B" or MCT 1488-R and "Series C" or MCT 1490-R, were named the holotypes of two titanosaur genera in 2005: ''Trigonosaurus'' and ''Baurutitan ...

Paleontologist
Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, ( gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brazilians
Brazilians ( pt, Brasileiros, ) are the citizens of Brazil. A Brazilian can also be a person born abroad to a Brazilian parent or legal guardian as well as a person who acquired Brazilian citizenship. Brazil is a multiethnic society, which means that it is home to people of many ethnic origins, and there is no correlation between one's stock and their Brazilian identity. Being Brazilian is a civic phenomenon, rather than an ethnic one. As a result, the degree to which Brazilian citizens identify with their ancestral roots varies significantly depending on the individual, the region of the country, and the specific ethnic origins in question. Most often, however, the idea of ethnicity as it is understood in the anglophone world is not popular in the country. In the period after the colonization of the Brazilian territory by Portugal, during much of the 16th century, the word "Brazilian" was given to the Portuguese merchants of Brazilwood, designating exclusively the name of ...

Bauru Group
The Bauru Group is a geological group of the Bauru Sub-basin, Paraná Basin in Minas Gerais, São Paulo, General Salgado, Itapecuru-Mirim, Mato Grosso, Brazil whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. Subdivisions According to a 2016 study: The Bauru Basin covers an area of approximately 379.362 km2 located almost exclusively in Brazil.., with selected outcrops in Northeastern Paraguay (Fúlfaro, 1996). This Cretaceous sedimentary succession reflects changing nonmarine environments, such as eolian, lacustrine, fluvial and alluvial fans. The Bauru Group was divided by Fernandes and Coimbra (1996) in four formations, namely Adamantina, Uberaba, Araçatuba and Marília. In 1998, Fernandes revised the group and recognize six formations, Uberaba, Vale do Rio do Peixe, Araçatuba, São José do Rio Preto, Presidente Prudente and Marília. The Adamantina Formation was divided in Vale do Rio do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Rio De Janeiro
Rio de Janeiro ( , , ; literally 'River of January'), or simply Rio, is the capital of the state of the same name, Brazil's third-most populous state, and the second-most populous city in Brazil, after São Paulo. Listed by the GaWC as a beta global city, Rio de Janeiro is the sixth-most populous city in the Americas. Part of the city has been designated as a World Heritage Site, named "Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea", on 1 July 2012 as a Cultural Landscape. Founded in 1565 by the Portuguese, the city was initially the seat of the Captaincy of Rio de Janeiro, a domain of the Portuguese Empire. In 1763, it became the capital of the State of Brazil, a state of the Portuguese Empire. In 1808, when the Portuguese Royal Court moved to Brazil, Rio de Janeiro became the seat of the court of Queen Maria I of Portugal. She subsequently, under the leadership of her son the prince regent João VI of Portugal, raised Brazil to the dignity of a k ...

Ootaxon
Egg fossils are the fossilized remains of eggs laid by ancient animals. As evidence of the physiological processes of an animal, egg fossils are considered a type of trace fossil. Under rare circumstances a fossil egg may preserve the remains of the once- developing embryo inside, in which case it also contains body fossils. A wide variety of different animal groups laid eggs that are now preserved in the fossil record beginning in the Paleozoic. Examples include invertebrates like ammonoids as well as vertebrates like fishes, possible amphibians, and reptiles. The latter group includes the many dinosaur eggs that have been recovered from Mesozoic strata. Since the organism responsible for laying any given egg fossil is frequently unknown, scientists classify eggs using a parallel system of taxonomy separate from but modeled after the Linnaean system. This "parataxonomy" is called ''veterovata''. History The first named oospecies was '' Oolithes bathonicae'', a name given provisi ...
