Alanqa
''Alanqa'' is a genus of pterodactyloid pterosaur from the Late Cretaceous period ( Cenomanian stage) of what is now the Kem Kem Beds of southeastern Morocco. The name ''Alanqa'' comes from the Arabic word العنقاء ''al- ‘Anqā’'', for a mythical bird of Arabian culture. Discovery Aided by local villagers, a team of paleontologists had been excavating at several locations in the Kem Kem Beds during April, and November to December 2008, uncovering remains of several different pterosaurs. The material was fragmentary, and the type locality for ''Alanqa'' is Aferdou N'Chaft, near the village of Begaa and to the north-east of Taouz. Description ''Alanqa'' is known only from five fragments of the front upper and lower jaws, and possibly a neck vertebra, representing the single type species ''Alanqa saharica''. Two of these fragments were first described, but not named, by Wellnhofer and Buffetaut in 1999, and referred to a pteranodontid. Three additional jaw specimens, ...

Kem Kem Beds
The Kem Kem Group (commonly known as the Kem Kem beds) is a geological group in the Kem Kem region of eastern Morocco, whose strata date back to the Cenomanian stage of the Late Cretaceous. Its strata are subdivided into two geological formations, the lower Gara Sbaa Formation and the upper Douira Formation. It is exposed on an escarpment along the Algeria–Morocco border. The unit unconformably overlies Paleozoic marine units of Cambrian, Silurian and Devonian age, and is itself capped by limestone platform rock of Cenomanian-Turonian age. It primarily consists of deltaic deposits. The lower Gara Sbaa Formation primarily consists of fine and medium grained sandstone, while the Douira Formation consists of fining-upwards, coarse-to-fine grained sandstones intercalated with siltstones, variegated mudstones, and occasional thin gypsiferous evaporites. Dinosaur remains are among the fossils that have been recovered from the group.Weishampel, David B; ''et al.'' (2004). "Dinosau ...

Azhdarchid
Azhdarchidae (from the Persian word , , a dragon-like creature in Persian mythology) is a family of pterosaurs known primarily from the Late Cretaceous Period, though an isolated vertebra apparently from an azhdarchid is known from the Early Cretaceous as well (late Berriasian age, about 140 million years ago). Azhdarchids included some of the largest known flying animals of all time, but smaller cat-size members have also been found. Originally considered a sub-family of Pteranodontidae, Nesov (1984) named the Azhdarchinae to include the pterosaurs ''Azhdarcho'', ''Quetzalcoatlus'', and ''Titanopteryx'' (now known as ''Arambourgiania''). They were among the last known surviving members of the pterosaurs, and were a rather successful group with a worldwide distribution. By the time of the end-Cretaceous mass extinction, most pterosaur families except for the Azhdarchidae disappear from the fossil record, but recent studies indicate a wealth of pterosaurian fauna, including pteran ...

Alanqidae
Azhdarchoidea (or azhdarchoids) is a group of pterosaurs within the suborder Pterodactyloidea, more specifically within the group Ornithocheiroidea. Pterosaurs belonging to this group lived throughout the Early and Late Cretaceous periods, with one tentative member, ''Tendaguripterus'', that lived in the Late Jurassic period. The largest azhdarchoids include members of the family Azhdarchidae, examples of these are '' Quetzalcoatlus'', '' Hatzegopteryx'', and ''Arambourgiania''. The Azhdarchoidea has been recovered as either closely related to the Ctenochasmatoidea, as the sister taxon of the Pteranodontoidea within the Ornithocheiroidea, or within the Tapejaroidea, which in turn was also within the Ornithocheiroidea. Classification Azhdarchoidea was given a phylogenetic definition by David Unwin in 2003. Unwin defined the group as the most recent common ancestor of '' Quetzalcoatlus'' and '' Tapejara'', and all its descendants.Unwin, D. M., (2003). "On the phylogeny and evolut ...

Thalassodromidae
Thalassodrominae or Thalassodromidae (meaning "sea runners", due to previous misconceptions of skimming behavior; they are now thought to be terrestrial predators) is a group of azhdarchoid pterosaurs from the Cretaceous period. Its traditional members come from Brazil, however, other possible members also come from other places, including the United States, Morocco, and Argentina. Thalassodrominae is considered either to be a subfamily within the pterosaur family Tapejaridae, or as a distinct family, Thalassodromidae, within the clade Neoazhdarchia, closely related to dsungaripterids or azhdarchids. Classification Thalassodrominae traditionally includes only two genera, ''Thalassodromeus'' and ''Tupuxuara'', and was defined to include them and any other descendants of their most recent common ancestor. The classification of thalassodromines is controversial. Some studies, including one by Lü and colleagues in 2008, have found that the thalassodromines are more closely related t ...

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 ...

Aerotitan Sudamericanus
''Aerotitan'' is a genus of large azhdarchid pterosaur known from the Late Cretaceous period (Maastrichtian stage) of what is now the Allen Formation of the Neuquén Basin in northern Patagonia, Argentina. Discovery and naming The type species ''Aerotitan sudamericanus'' was named and described in 2012 by Fernando Novas, Martin Kundrat, Federico Agnolín, Martin Ezcurra, Per Erik Ahlberg, Marcelo Isasi, Alberto Arriagada and Pablo Chafrat. The generic name is derived from Greek ἀήρ, ''aer'', "air", and Titan, in reference to the fact the species represents a large flying reptile. The specific name refers to its provenance from South America. The holotype, MPCN-PV 0054, has been recovered near the Bajo de Arriagada site, in Patagonia, from a layer of the upper Allen Formation. It consists, according to the original description, of a partial rostrum with a preserved length of . This snout is elongated and transversely compressed and the jaws are toothless. The wingspan ...

Keresdrakon
''Keresdrakon'' is an extinct genus of tapejaromorph pterosaur from the Goio-Erê Formation of Brazil, which dates back to the Late Cretaceous period (Turonian-Campanian stages), 94 to 71 million years ago. ''Keresdrakon'' contains a single species, ''Keresdrakon vilsoni''. Discovery In 1971, Alexandre Dobruski and his son João Gustavo Dobruski, discovered a fossil site near Cruzeiro do Oeste in Paraná. Only in 2011, paleontologists Paulo César Manzig and Luiz C. Weinschütz visited the location. A bone bed proved to be present with hundreds of specimens of a pterosaur that in 2014 was named ''Caiuajara''. Among them were some bones belonging to a second pterosaur species. These remains, both of ''Caiuajara'' and the new taxon, were prepared by volunteer Vilson Greinert. In 2019, the type species ''Keresdrakon vilsoni'' was named and described by Alexander Wilhelm Armin Kellner, Luiz Carlos Weinschütz, Borja Holgado, Renan Alfredo Machado Bantim and Juliana Manso Sayão. ...

Apatorhamphus
''Apatorhamphus'' is an extinct genus of azhdarchoid pterosaur from the Kem Kem Group of Morocco. It might have been part of the Chaoyangopteridae. It is only known from a few snout fragments and it likely had a wingspan of between Discovery and naming During a visit in 2016 to the Tafilalt phosphate mine on the Aferdou N'Chaft plateau, near Hassi el Begaa, in Er Rachidia, British paleontologist David Michael Martill purchased the jaw fragment of a pterosaur from miners (specimen ''FSAC-KK 5010''). They had dug a tunnel in a thin fossil-containing layer on the edge of a quarry and finds were offered for sale there. These fossils belong to strata that belong to the Kem Kem Beds and date to the Cretaceous period, between the Albian to Cenomanian. In 2020, the new genus and species ''Apatorhamphus gyrostega'' was named and described by James McPhee, Nizar Ibrahim, Alex Kao, David M. Unwin, Roy Smith, and David M. Martill. McPhee ''et al.'' also referred various earlier finds to ...
