Sarcosuchus (), from Ancient Greek σάρξ (sárx), meaning "flesh", and Σοῦχος (Soûkhos), meaning "Sobek", is an extinct genus of crocodyliform that lived during the Early Cretaceous, from the late Hauterivian to the early Albian stages, 130 to 112 million years ago of what is now Africa and South America. It was one of the largest pseudosuchians, with the largest specimen of S. imperator reaching approximately long and weighing up to . It is known from two species; S. imperator from the early Albian Elrhaz Formation of Niger, and S. hartti from the Late Hauterivian of northeastern Brazil. Other

extinct genus of pterosaurs

Tupuxuara is a genus of thalassodromid pterosaur that lived during the Albian age of the Early Cretaceous, about 112 million years ago. Its remains were found in what is now the Romualdo Formation of the Santana Group in Brazil. Tupuxuara was named in 1988 by paleontologists Alexander Kellner and Diógenes de Almeida Campos. The name Tupuxuara means "familiar spirit" referring to a familiar spirit in the mythology of the Tupi people in Brazil. Two species have been named, T. longicristatus, the type species, and T. leonardii. An additional species has been named in 2009, T. deliradamus. However

Thalassodromeus is a genus of pterosaur that lived in what is now Brazil during the Early Cretaceous period, about a hundred million years ago. The original skull, discovered in 1983 in the Araripe Basin of northeastern Brazil, was collected in several pieces. In 2002, the skull was made the holotype specimen of Thalassodromeus sethi by palaeontologists Alexander Kellner and Diogenes de Almeida Campos. The generic name means "sea runner" (in reference to its supposed mode of feeding), and the specific name refers to the Egyptian god Seth due to its crest being supposedly reminiscent of Seth's

Tropeognathus (meaning "keel jaw") is a genus of large pterosaurs from the late Early Cretaceous of South America. This genus is considered to be a member of the family Anhangueridae, but several studies have also recovered it within another family called Ornithocheiridae. Both of these families are diverse groups of pterosaurs known for their keel-tipped snouts and large size. With an estimated wingspan around , Tropeognathus is regarded as the largest pterosaur found in the Southern Hemisphere, only rivaled by the huge azhdarchids. The type and only species is Tropeognathus mesembrinus. Foss

Tupandactylus (meaning "Tupâ or Tupan finger", in reference to a personification of the Tupi supreme deity) is a genus of tapejarid pterodactyloid pterosaur from the Early Cretaceous Crato Formation of Brazil. It is known from two species, T. imperator and T. navigans, though it has been suggested that there is only a single, highly sexually dimorphic species (which would then be T. imperator). T. imperator was described in 1997 by D. A. Campos and Alexander W. A. Kellner, who assigned it to Tapejara. Six years later, T. navigans was named and also assigned to Tapejara. In 2007, two efforts to

Cearadactylus is an extinct genus of large anhanguerid pterosaur from the Early Cretaceous (Albian age) Romualdo Formation of Brazil. The only known species is C. atrox, described and named in 1985 by Giuseppe Leonardi and Guido Borgomanero. The name refers to the Brazilian state Ceará, and combines this with Greek daktylos, "finger", a reference to the wing finger of pterosaurs. The Latin atrox means "frightful", a reference to the fearsome dentition of the species.

Araripesuchus is a genus of extinct crocodyliform that existed during the Cretaceous period of the late Mesozoic era some 125 to 66 million years ago. Araripesuchus is generally considered to be a notosuchian (belonging to the clade Mesoeucrocodylia), characterized by the varied teeth types and distinct skull elements. Seven species have been referred to Araripesuchus, though it has been argued that the phylogenetic position of this genus is uncertain, and that taxonomic revision is required.

Lepidotes (from , 'covered with scales') (previously known as Lepidotus) is an extinct genus of Mesozoic ray-finned fish. It has long been considered a wastebasket taxon, characterised by "general features, such as thick rhomboid scales and, for most of the species, by semi-tritorial or strongly with dozens of species assigned to it. Fossils attributed to Lepidotes have been found in Jurassic and Cretaceous rocks worldwide. It has been argued that Lepidotes should be restricted to species closely related to the type species L. gigas, which are only known from the Early Jurassic of Western and

Uberabasuchus ("Uberaba crocodile") is an extinct genus of crocodylomorph from the Late Cretaceous Serra da Galga Formation of Brazil. It appears to have a high skull like that of the sebecosuchians, but differs from them in having teeth with circular cross-section. Thus, rather than slicing flesh and blood vessels, it is likely to have inflicted powerful crushing bites . The post-crania and the geology suggesting an arid climate indicate that Uberabasuchus was likely a terrestrial predator.

Santanachelys gaffneyi is an extinct species of sea turtle. It is the only species in the genus Santanachelys, which itself is a member of the extinct family Protostegidae. The species was first described from a 20-centimeter long fossil specimen unearthed in 1998 from the Santana Formation of eastern Brazil. From the rock layer from which it was excavated, it was determined that the specimen was from the Early Cretaceous period (112 million years old). It is therefore one of the oldest known sea turtles. but a new fossil named Desmatochelys padillai in 2015 is estimated to be as old as 120 mi

The Axelrodichthys of the Lower Cretaceous frequented both brackish and coastal marine waters (lagoon-coastal environment) while the most recent species lived exclusively in fr

Torukjara is an extinct genus of tapejarin pterodactyloid pterosaurs from the Early Cretaceous "Pterosaur Graveyard" (Caiuá Group) of Brazil. The genus contains a single species, T. bandeirae, known from several specimens. The Torukjara fossil material was originally assigned to Caiuajara, but several anatomical differences indicate that both similar species coexisted in the ecosystem.

Sphenodiscus is an extinct genus of acanthoceratacean ammonite. The genus has been found from many continents and is thought to have had a large global distribution during the Maastrichtian stage of the Late Cretaceous. It was one of the last ammonoids to have evolved before the entire subclass became extinct during the Paleocene, which was directly after the Cretaceous–Paleogene extinction event.

Atlanticopristis (meaning "Atlantic saw") is an extinct genus of sclerorhynchoid that lived during the Late Cretaceous (Cenomanian) of what is now the Northeast Region of Brazil, between 100.5 and 93.9 million years ago.

Gueragama is an extinct genus of iguanian lizard from the Cretaceous of Brazil. It belongs to a group of iguanians called Acrodonta, whose living members include chameleons and agamids and are currently restricted to the Old World. Gueragama is the only acrodont known from South America, providing evidence that the group once ranged across much of Gondwana and only became restricted to the Old World after the supercontinent broke apart. The type species, Gueragama sulamericana, was named in 2015 on the basis of an isolated lower jaw from Goio-Erê Formation in the Bauru Basin, which was deposit
