Gondwanatitan was a titanosaurian sauropod dinosaur. Gondwanatitan was found in Brazil, at the time part of the southern supercontinent Gondwana, in the late Cretaceous Period. Like some other sauropods, Gondwanatitan was tall and ate tough shoots and leaves off of the tops of trees. G. faustoi's closest relative was Aeolosaurus.
Maxakalisaurus is a genus of titanosaur dinosaur, found in the Adamantina Formation of Brazil, in the state of Minas Gerais in 1998. The genus name is derived from the tribe of the Maxakali; Topa is one of their divinities.
Mariliasuchus is an extinct genus of Late Cretaceous notosuchian crocodyliforms found near Marilia, Brazil. The first bone remains were found and collected in 1995 by Brazilian paleontologist William Nava, in red rocks from the fossiliferous Adamantina Formation. Four years later, it was described as Mariliasuchus amarali, by Brazilian paleontologists Ismar de Souza Carvalho and Reinaldo J. Bertini.
Montealtosuchus was an extinct genus of terrestrial crocodyliform. It was discovered in 2004 in the Bauru Basin of Brazil, from Campanian-Maastrichtian deposits of the Adamantina Formation. The species was described in 2007, and assigned to the family Peirosauridae. The type species is M. arrudacamposi. The genus takes its name from the type locality in Monte Alto municipality.
Peirosauridae is a Gondwanan family of mesoeucrocodylians that lived during the Cretaceous period. It was a clade of terrestrial crocodyliforms that evolved a rather dog-like skull, and were terrestrial carnivores. It was phylogenetically defined in 2004 as the most recent common ancestor of Peirosaurus and Lomasuchinae and all of its descendants. Lomasuchinae is a subfamily of peirosaurids that includes the genus Lomasuchus.
Sphagesaurus is an extinct genus of sphagesaurid notosuchian crocodylomorph from the Late Cretaceous of southwest São Paulo, southern Brazil.
The Adamantina Formation is a geological formation in the Bauru Basin of western São Paulo state, in southeastern Brazil.
Caririsuchus is an extinct genus of peirosaurid crocodylomorph. Fossils have been found from the Romualdo Formation of the Santana Group in the Araripe Basin in northeastern Brazil, dating back to the Albian stage of the Early Cretaceous. It was about 1.5 metres (4.9 ft) in length.
Morrinhosuchus is an extinct genus of notosuchian crocodyliform from the Late Cretaceous Adamantina Formation of Brazil. It is known from a mandible and a portion of the front of the skull collected from the municipality of Monte Alto in São Paulo state. Morrinhosuchus refers to Morrinho de Santa Luzia, a hill nearby the collection site of the holotype, while luziae refers to the chapel of Santa Luzia, which is located on top of the hill.
Stratiotosuchus is an extinct genus of baurusuchid mesoeucrocodylian from the Adamantina Formation in Brazil. It lived during the Late Cretaceous. The first fossils were found in the 1980s, and the type species Stratiotosuchus maxhechti was named in 2001. A hyperpredator, it and other baurusuchids may have filled niches occupied elsewhere by theropod dinosaurs.
Brasiliguana is a genus of iguanian lizard which lived during the late Cretaceous period in what is now Brazil. It is known from the holotype MN 7230-V, an isolated left maxilla with partially preserved teeth, which was found in the Upper Cretaceous Adamantina Formation, part of the Bauru Group of São Paulo State, southeast Brazil. Brasiliguana was named by William R. Nava and Agustín G. Martinelli in 2011 and the type species is Brasiliguana prudentis. The generic name refers to its provenance from the Late Cretaceous of Brazil and iguana, from the South American and Caribbean aboriginal language meaning "lizard". The specific name, prudentis, refers to Presidente Prudente Municipality, where the holotype was found.
Campinasuchus is an extinct genus of baurusuchid mesoeucrocodylian from Minas Gerais State of Brazil.
Caipirasuchus is an extinct genus of sphagesaurid notosuchians known from the Late Cretaceous of northern São Paulo State, southeastern Brazil. The type species, C. paulistanus, was named in 2011. A second species, C. montealtensis, was referred to Caipirasuchus in 2013 after having been named in 2008 as a species of Sphagesaurus. A third species, C. stenognathus, was described in 2014. A fourth species, C. mineirus, was described in 2018. A fifth species, C. attenboroughi, was named in 2021 in honour of David Attenborough.
Caryonosuchus is an extinct genus of sphagesaurid notosuchian known from the Late Cretaceous of São Paulo State, southeastern Brazil.
Labidiosuchus is an extinct genus of notosuchian crocodyliforms from Minas Gerais State, southeastern Brazil. Labidiosuchus had a very bizarre dentition and its lower jaw had a Y-shaped outline.
Brasilotitan is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Adamantina Formation of Brazil. The type species is Brasilotitan nemophagus. Brasilotitan was a small titanosaur with a squared-off snout, and may be closely related to another Brazilian titanosaur, Uberabatitan.
The year 2011 in Archosaur paleontology was eventful. Archosaurs include the only living dinosaur group — birds — and the reptile crocodilians, plus all extinct dinosaurs, extinct crocodilian relatives, and pterosaurs. Archosaur palaeontology is the scientific study of those animals, especially as they existed before the Holocene Epoch began about 11,700 years ago. The year 2011 in paleontology included various significant developments regarding archosaurs.
The Presidente Prudente Formation is a geological formation of the Bauru Group in the Paraná Basin, located in Brazil whose strata date back to the Late Campanian to Early Maastrichtian.
Arrudatitan is an extinct genus of titanosaur sauropod dinosaur known from the Late Cretaceous (Campanian-Maastrichtian)-aged Adamantina Formation of Brazil. The type species, A. maximus, was named and described in 2011 as a species of Aeolosaurus, but was separated into its own genus in 2021. It was relatively gracile for a titanosaur.
The Serra da Galga Formation is a geological formation in Minas Gerais state of southeastern Brazil. Its strata date back to the Maastrichtian, and are part of the Bauru Group. It was originally considered a member of the Marília Formation.
