Kariridraco
''Kariridraco'' is a genus of tapejarid pterosaur from the Early Cretaceous-aged Romualdo Formation, Brazil. The genus contains a single species, ''Kariridraco dianae''.. Discovery and naming Local workers in Ceará at some unknown location collected a concretion containing the back of the skull of a pterosaur. To enhance its value, they glued the snout of another specimen to the front of the skull. Ultimately, they donated the find to the ''Museu de Paleontologia Plácido Cidade Nuvens''. Before his death in 2016, Nuvens let other experts study the concretion. The falsification was then discovered. They concluded that the fossil represented a species new to science. There were no indications that the snout belonged to the same species. The new genus and species ''Kariridraco dianae'' was named and described in 2021, by Gabriela M. Cerqueira, Mateus A.C. Santos, Maikon F. Marks, Juliana Manso Sayão and Felipe Lima Pinheiro, based on the holotype MPSC R 1056, a fairly complete sku ...

Pterosaurs
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Romualdo Formation
The Romualdo Formation is a geologic Konservat-Lagerstätte in northeastern Brazil's Araripe Basin where the states of Pernambuco, Piauí and Ceará come together. The geological formation, previously designated as the Romualdo Member of the Santana Formation, named after the village of Santana do Cariri, lies at the base of the Araripe Plateau. It was discovered by Johann Baptist von Spix in 1819. The strata were deposited during the Aptian stage of the Early Cretaceous in a lacustrine rift basin with shallow marine incursions of the proto-Atlantic. At that time, the South Atlantic was opening up in a long narrow shallow sea. The Romualdo 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalassodrominae
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 ...

Taxa Described In 2021
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tupuxuara Longicristatus
''Tupuxuara'' is a genus of large, crested, and toothless pterodactyloid pterosaur from the Early Cretaceous period ( Albian stage) of what is now the Romualdo Formation of the Santana Group, Brazil, about 125 to 112 million years ago. ''Tupuxuara'' is a close relative of '' Thalassodromeus'', and both form a group that is either called Thalassodrominae (if placed within the family Tapejaridae) or Thalassodromidae (if placed within the clade Neoazhdarchia). Discovery The genus was named and described by Alexander Kellner and Diógenes de Almeida Campos in 1988.Kellner, A.W.A., and Campos, D.A. (1988). "Sobre un novo pterossauro com crista sagital da Bacia do Araripe, Cretaceo Inferior do Nordeste do Brasil. (Pterosauria, Tupuxuara, Cretaceo, Brasil)."

Thalassodromeus
''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 crown. Other scholars have pointed out that the crest was instead similar to the crown of Amon. A jaw tip was assigned to ''T. sethi'' in 2005, became the basis of the new genus '' Banguela'' in 2014, and assigned back to ''Thalassodromeus'' as the species ''T. oberlii'' in 2018. Another species (''T. sebesensis'') was described in 2015 based on a supposed crest fragment, but this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tapejarinae
Tapejaridae (from a Tupi word meaning "the old being") are a family of pterodactyloid pterosaurs from the Cretaceous period. Members are currently known from Brazil, England, Hungary, Morocco, Spain, the United States, and China. The most primitive genera were found in China, indicating that the family has an Asian origin. Description Tapejarids were small to medium-sized pterosaurs with several unique, shared characteristics, mainly relating to the skull. Most tapejarids possessed a bony crest arising from the snout (formed mostly by the premaxillary bones of the upper jaw tip). In some species, this bony crest is known to have supported an even larger crest of softer, fibrous tissue that extends back along the skull. Tapejarids are also characterized by their large nasoantorbital fenestra, the main opening in the skull in front of the eyes, which spans at least half the length of the entire skull in this family. Their eye sockets were small and pear-shaped. Studies of tapejarid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaoyangopteridae
Chaoyangopteridae (or chaoyangopterids) is a family of pterosaurs within the larger group Azhdarchoidea. Chaoyangopterids lived mostly during the Early Cretaceous period, though possible members, ''Microtuban'', '' Xericeps'' and ''Argentinadraco'', may extend the fossil range to the Late Cretaceous. History The clade Chaoyangopteridae was first defined in 2008 by Lü Junchang and David Unwin as: "'' Chaoyangopterus'', '' Shenzhoupterus'', their most recent common ancestor and all taxa more closely related to this clade than to '' Tapejara'', ''Tupuxuara'' or ''Quetzalcoatlus''". Based on neck and limb proportions, it has been suggested they occupied a similar ecological niche to that of azhdarchid pterosaurs, though it is possible they were more specialized as several genera occur in Liaoning, while azhdarchids usually occur by one genus in a specific location. Description Chaoyangopterids are distinguished from other pterosaurs by several traits of the nasoantorbital fenestra, a ...
