Thalassodromids
Thalassodromidae (meaning "sea runners") is a group of azhdarchoid pterosaurs from the Early Cretaceous (Albian) of Brazil. All known definitive members come from the Romualdo Formation of Brazil, which include the type genus ''Thalassodromeus'', as well as ''Tupuxuara'' and ''Kariridraco''. Proposals of additional thalassodromid genera from the Late Cretaceous are controversial and have not been supported. The classification of Thalassodromidae is quite controversial and disputed. It was initially denominated Thalassodrominae, as a subfamily within the group Tapejaridae. However, opposing studies regarding its placement have argued that its members were more closely related to azhdarchids and dsungaripterids, while also elevating it to family level. Though the relationship with tapejarids remains supported by many studies, it has been proposed that it is preferable to retain them as a distinct family for consistency of communication.

Thalassodromeus Sethi
''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 2015, and assigned back to ''Thalassodromeus'' as the species ''T. oberlii'' in 2018, though other researchers consider it a valid genus. Another species (''T. sebesensis'') was described i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tupuxuara Leonardii
''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 2013, ''T. deliradamus''. However, the validity of this species has been put into question and it may not even belong to ''Tupuxuara''. ''Tupuxuara'' was quite large in size. It had a big crest at the back portion of its head, stemming from the snout. This crest is most likely an indicator of sexual maturity, given that it appears more prominently in mature individuals. The beak of ''Tupuxuara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neoazhdarchia
Azhdarchoidea ( , meaning " azhdarchid-like forms") is a group of pterosaurs within the suborder Pterodactyloidea. 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. Remains of this group have been found in the Americas, Africa, and Eurasia, suggesting that they probably had a global distribution. Azhdarchoids are generally distinguished from other pterodactyloids by their relatively low arm-to-leg-length ratio, suggesting that they were more proficient in moving on the ground than pterosaurs like ''Pteranodon'' or '' Anhanguera'' (which had very long arms relative to the length of their legs). This has led some researchers to suggest that many azhdarchoids, such as the azhdarchids and dsungaripterids, may have been primarily terrestrial, while retaining the ability to fly when necessary.

Tapejaridae
Tapejaridae (from a Tupi language, Tupi word meaning 'the lord of the ways') is a Family (biology), family of azhdarchoid pterosaurs from the Cretaceous Period (geology), 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 so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Azhdarchidae
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 include some of the largest flying animals discovered, 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. Previously it was thought that by the end of the Cretaceous, most pterosaur families except for the Azhdarchidae disappeared from the fossil record, but recent studies indicate a wealth of pterosaurian fauna, including ...

Chaoyangopterinae
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.
