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

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

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

Tetrapodophis (Greek meaning "four-footed snake") is an extinct genus of lizard from the Early Cretaceous (Aptian) aged Crato Formation of Brazil. It has an elongated snake-like body, with four disproportionately short limbs. The species is known from one fossil specimen.

Arthurdactylus is a genus of pterodactyloid pterosaur from the Early Cretaceous Crato Formation of northeastern Brazil. It was a medium-sized pterosaur, with a wingspan of and body mass of .

Brasileodactylus is an extinct genus of anhanguerian pterosaur from the Early Cretaceous (Aptian age) lower Santana Formation of Chapada do Araripe, Ceará, Brazil.

Lacusovagus (meaning "lake wanderer") is a genus of azhdarchoid pterodactyloid pterosaur from the Lower Cretaceous of Brazil.

Ludodactylus (meaning "play finger") is a genus of anhanguerid pterodactyloid pterosaur from the Early Cretaceous period (Aptian stage) of what is now the Crato Formation of the Araripe Basin in Ceará, Brazil. The type and only species is L. sibbicki. The generic name Ludodactylus refers to the fact that the animal had the combination of teeth and a Pteranodon-like head crest, similar to many toy pterosaurs, and no such creature was known to exist until the discovery of Ludodactylus. However, Ludodactylus is not the only pterosaur now known to possess these features, its very close relative Ca

Cratoavis is a genus of enantiornithines. The type and only currently described species is C. cearensis, from the Early Cretaceous of Araripe Basin, Ceará, Brazil. The fossil, an articulated skeleton with feathers attached to the wings and surrounding the body, extends considerably the temporal record of the group at South America.

Axelrodichthys is an extinct genus of mawsoniid coelacanth from the Cretaceous of Africa, North and South America, and Europe. Several species are known, the remains of which were discovered in the Lower Cretaceous (Aptian-Albian) of Brazil, North Africa, and possibly Mexico, as well as in the Upper Cretaceous of Morocco (Cenomanian), Madagascar (Coniacian –Santonian) and France (Lower Campanian to Lower Maastrichtian). 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

Aymberedactylus (meaning "small lizard finger") is a genus of tapejarid pterosaur from the Early Cretaceous Crato Formation of Brazil. It contains a single species, A. cearensis.

Dastilbe is an extinct genus of prehistoric marine & freshwater ray-finned fish from the Early Cretaceous of Brazil. It was a relative of modern milkfish.

Gondwanagaricites (meaning "Gondwanan mushroom fossil") is an extinct monotypic genus of gilled fungus in the order Agaricales from the Early Cretaceous Crato Formation of Brazil. It contains the single species G. magnificus, and it is the oldest known mushroom fossil known to date.

Cladocyclus (derived from the Greek κλάδος/kládos ("branch") and κύκλος/kýklos ("circle")) is an extinct genus of marine ichthyodectiform ray-finned fish from the middle Cretaceous. It was a predator of about in length.

Araripichthys is an extinct genus of marine ray-finned fish that lived from the Aptian to Coniacian stages of the Cretaceous period. The genus is named after the Araripe Basin, where it was found in the Crato and Santana Formations. Other fossils of the genus have been found at Goulmima in Morocco, the Tlayua Formation of Mexico and the Apón Formation of Venezuela.

Araripemys is an extinct marine turtle genus from 112 to 109 million years ago, in the Early Cretaceous Crato and Romualdo Formations of the Araripe Basin in northeastern Brazil. It is one of the oldest known pleurodires. thumb|left|Araripemys barretoi

Susisuchus is an extinct genus of neosuchian mesoeucrocodylian crocodyliform from the Early Cretaceous of Brazil. Fossils have been found from the Nova Olinda Member of the Aptian-age Crato Formation in the Araripe and Lima Campos Basins of northeastern Brazil. Named in 2003, Susisuchus is the sole member of the family Susisuchidae, and is closely related to the clade Eusuchia, which includes living crocodilians. The type species is S. anatoceps, known from a single partial articulated skeleton that preserves some soft tissue. A second species, S. jaguaribensis, was named in 2009 from fragment

Calamopleurus is a prehistoric genus of marine halecomorph ray-finned fish from the Early Cretaceous of South America and northern Africa. It was a relative of the modern bowfin, with both belonging to the family Amiidae. C. cylindricus was among the largest known amiids, rivaling the giant Paleocene bowfin Amia pattersoni in size. However, both were slightly smaller than Melvius and Amia basiloides, the two largest known amiids. It is one of the earliest known amiids to evolve a large body size.

Araripelepidotes is a genus of ginglymodian fish.
