Araripe Basin
The Araripe Basin () is a rift basin covering about ,Neto et al., 2013, p.1 in Ceará, Piauí and Pernambuco states of northeastern Brazil. It is bounded by the Patos and Pernambuco lineaments, and is situated east of the Parnaíba Basin, southwest of the Rio do Peixe Basin and northwest of the Tucano and Jatobá Basins. The basin has provided a variety of unique fossils in the Crato and Santana Formations and includes the Araripe Geopark, a member of the UNESCO Global Geoparks since 2006. The pterosaurs ''Araripesaurus'' and ''Araripedactylus'' (now considered a ''nomen dubium''), crocodylian ''Araripesuchus'', the turtle ''Araripemys'', amphibian '' Arariphrynus'', the fish ''Araripelepidotes'' and the insect '' Araripenymphes'' were named after the basin. The bituminous shales of the Ipubi Formation in the Araripe Basin have potential for shale gas development.Neto et al., 2013, p.3 Basin history The tectono-sedimentary evolution of the Araripe Basin, located in the Bor ...

Santana Formation
The Santana Group is a geologic group, formerly included as the middle part of the Araripe Group, in the Araripe Basin of northeastern Brazil. The group comprises the Crato, Ipubi and Romualdo Formations and is dated to the Aptian to Albian stages of the Early Cretaceous. The formations of the group were deposited in a lacustrine to subtidal shallow marine environment in the Araripe rift basin.Santana Group
at Fossilworks.org The Santana Group has provided a rich assemblage of fossils; flora, fish, arthropods insects, turtles, snakes, dinosaurs, such as ''

Crato Formation
The Crato Formation is a geologic formation of Early Cretaceous ( Aptian) age in northeastern Brazil's Araripe Basin. It is an important Lagerstätte (undisturbed fossil accumulation) for palaeontologists. The strata were laid down mostly during the Aptian age, about 113 million years ago. It thought to have been deposited in a semi-arid lacustrine wetland environment.Ribeiro et al., 2021 The Crato Formation earns the designation of Lagerstätte due to an exceedingly well preserved and diverse fossil faunal assemblage. Some 25 species of fossil fishes are often found with stomach contents preserved, enabling paleontologists to study predator-prey relationships in this ecosystem. There are also fine examples of pterosaurs, reptiles and amphibians, invertebrates (particularly insects), and plants. Even dinosaurs are represented: a new maniraptor was described in 1996. The unusual taphonomy of the site resulted in limestone accretions that formed nodules around dead organisms, pr ...

Chapada Do Araripe
The Chapada do Araripe, also known as the Serra do Araripe, is a ''chapada'' (plateau) in northeastern Brazil. The chapada forms the boundary of Ceará and Pernambuco states, and forms the watershed between the Jaguaribe River of Ceará, which flows northward into the Atlantic, and the much larger basin of the São Francisco River of Pernambuco and neighboring states, which drains eastward into the Atlantic. The Santana Formation, which is rich with fossils from the early Cretaceous, lies at the base of the chapada. The Araripe manakin (''Antilophia bokermanni''), a bird only described in 1998, is endemic Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found else ... to Chapada do Araripe.

Lineament
''See also Line (geometry)'' A lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault. Typically a lineament will appear as a fault-aligned valley, a series of fault or fold-aligned hills, a straight coastline or indeed a combination of these features. Fracture zones, shear zones and igneous intrusions such as dykes can also be expressed as geomorphic lineaments. Lineaments are often apparent in geological or topographic maps and can appear obvious on aerial or satellite photographs. There are for example, several instances within Great Britain. In Scotland the Great Glen Fault and Highland Boundary Fault give rise to lineaments as does the Malvern Line in western England and the Neath Disturbance in South Wales. The term 'megalineament' has been used to describe such features on a continental scale. The trace of the San Andreas Fault might be considered an example.Whitten & Brooks, The Penguin Dictionary of Ge ...

Araripesuchus
''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. Six species of ''Araripesuchus'' are currently known. They are generally considered to be notosuchians (belonging to the clade Mesoeucrocodylia), characterized by their varied teeth types and distinct skull elements. This genus consists of six species: ''A. buitreraensis'', discovered in Argentina, ''A. wegeneri'', discovered in Cameroon and Niger, ''A. rattoides'', discovered in Niger, ''A. tsangatsangana'', discovered in Madagascar, ''A. gomesii'' (the type species), discovered in Brazil and another species discovered in Argentina, ''A. patagonicus''. Description Its length was about with a weight of . ''Araripesuchus'' can be distinguished by their laterally bulged edges of the snout, with the bulge being the most prominent around the area of an enlarged maxillary tooth. The snout and premaxilla are also smoother than that o ...

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ...

Araripedactylus
''Araripedactylus'' was a large genus of pterodactyloid pterosaur, known from a single wing bone found in the Early Cretaceous Santana Formation of Brazil. The genus was in 1977 named by Peter Wellnhofer who, unaware that the name ''Araripesaurus'' had been published by Price in 1971, presumed he was naming the first pterosaur genus from Brazil. The genus name refers to the Araripe Plateau and combines this with ''daktylos'', Greek for "finger", a common element in pterosaur names since ''Pterodactylus''. The type species is ''Araripedactylus dehmi''; the specific name honours the German paleontologist Richard Dehm, a professor at the Munich institute that acquired the only known specimen in 1975. The holotype, BSP 1975 I 166, consists of a single phalanx, the first of the right wing finger, embedded in an elongated chalk nodule. When the nodule was split to reveal the fossil, its distal end was damaged. The exemplar is that of an adult individual. The phalanx has a length of 5 ...

Araripesaurus
''Araripesaurus'' is a genus a pterosaur belonging to the suborder Pterodactyloidea, it was discovered in the Romualdo Formation of the Santana Group in northeastern Brazil, which dates back to the Aptian and Albian of the Early Cretaceous. The type species is ''A. castilhoi''. Discovery and naming The genus was named in 1971 by Brazilian paleontologist Llewellyn Ivor Price. The type species is ''Araripesaurus castilhoi''. The genus name refers to the Araripe Plateau. The specific name honors the collector Moacir Marques de Castilho, who in 1966 donated the chalk nodule containing the fossil. The holotype, DNPM (DGM 529-R), consists of a partial wing, including distal fragments of the radius and ulna, carpals, all metacarpals and several digits. The specimen was a subadult. Its wingspan was estimated at . Two other possible specimens are known; both consist of wing fragments and are roughly a third larger than the holotype, and were referred to the genus by Price. In 1985 Peter ...

Pterosaur
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectiv ...

UNESCO Global Geopark
UNESCO Global Geoparks (UGGp) are geoparks certified by the UNESCO Global Geoparks Council as meeting all the requirements for belonging to the Global Geoparks Network (GGN). The GGN is both a network of geoparks and the agency of the United Nations Educational, Scientific and Cultural Organization (UNESCO). that administers the network. The agency was founded in 2004 in partnership with the International Union of Geological Sciences (IUGS). The network was set up to conserve earth's geological heritage, as well as to promote the sustainable research and development by the concerned communities. To implement these goals they adopted the concept of geopark, a term that had already been in use for one of the proposed parks. Geoparks were conceived as :"single, unified geographical areas where sites and landscapes of international geological significance are managed with a holistic concept of protection, education and sustainable development." As the geopark did not naturally conform ...
