Trigonosaurus
''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 ...

Caieiria Allocaudata
''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 t ...

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] |
Saltasaurid
Saltasauridae (named after the Salta region of Argentina where they were first found) is a family of armored herbivorous sauropods from the Upper Cretaceous. They are known from fossils found in South America, Asia, North America, and Europe. They are characterized by their vertebrae and feet, which are similar to those of ''Saltasaurus'', the first of the group to be discovered and the source of the name. The last and largest of the group and only one found in North America, '' Alamosaurus'', was in length and one of the last sauropods to go extinct. Most of the saltasaurids were smaller, around in length, and one, '' Rocasaurus'', was only long. Like all sauropods, the saltasaurids were quadrupeds, their necks and tails were held almost parallel to the ground, and their small heads had only tiny, peg-like teeth. They were herbivorous, stripping leaves off of plants and digesting them in their enormous guts. Although large animals, they were smaller than other sauropods of th ...

Fossils Of Brazil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolut ...

Cretaceous Brazil
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by th ...
