Tapejara (pterosaur)
''Tapejara'' (from a Tupi word meaning "the old being") is a genus of Brazilian pterosaur from the Cretaceous Period (Santana Formation, dating to about 127 to 112 million years ago). ''Tapejara'' crests consisted of a semicircular crest over the snout, and a bony prong which extended back behind the head. It was a small pterosaur, with a wingspan of approximately . Species and classification The type species and only one currently recognized as valid by most researchers, is ''T. wellnhoferi''. The specific name honors German paleontologist Peter Wellnhofer. Two larger species, originally named ''Tapejara imperator'' and ''Tapejara navigans'', were later classified in the genus ''Tapejara''. However, several studies have shown that ''T. imperator'' and ''T. navigans'' are significantly different from ''T. wellnhoferi'' and therefore were reclassified into new genera. The species ''T. imperator'' was given its own genus, '' Tupandactylus'', by Alexander Kellner and Diogenes de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aptian
The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 Ma and lasted approximately 1 to 1.3 million years. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma.Archangelsky, Sergio.The Ticó Flora (Patagonia) and the Aptian Extinction Event" ''Acta Paleobotanica'' 41(2), 2001, pp. 115-22. Stratigraphic definitions The Aptian was named after the small city of Apt in the Provence region of France, which is also known ...

Tapejarini
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 tapejari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huaxiapterus
''Huaxiapterus'' (meaning "Hua Xia hinawing") is a genus of tapejarid pterodactyloid pterosaur from the Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. It is the second genus of tapejarid from this formation, after '' Sinopterus''. Three species are known (''H. jii'', "''H. corollatus''", and "''H. benxiensis''"), though they may not actually form a natural group with each other. It was first named by Lü Junchang and Yuan Chongxi. Discovery The type species of ''Huaxiapterus'' is ''H. jii'', which is based on GMN-03-11-001, a nearly complete skeleton and skull. While it was initially separated from the closely related '' Sinopterus'' by several characters including its larger size and larger crest, later studies showed that it was in fact more closely related to ''Sinopterus dongi'' than to either of the other two species of ''Huaxiapterus''. Some researchers have considered ''H. jii'' to be a species of ''Sinopterus'' for this reason, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eopteranodon Lii
''Eopteranodon'' (meaning "dawn ''Pteranodon'' (toothless wing)") is a genus of tapejarid pterosaur from the Aptian-age Lower Cretaceous Yixian Formation of Beipiao City, Liaoning, China. The genus was named in 2005 by paleontologists Lü Junchang and Zhang Xingliao. The type and only species is ''Eopteranodon lii''. Description and classification ''Eopteranodon'' is based on the type specimen or holotype BPV-078, an incomplete skeleton and skull. Its skull, including a large crest, was toothless and similar to that of ''Pteranodon''. The skull lacks the point of the snout but it was in life less than 200 millimeters long (7.9 inches), and the animal had a wingspan of about 1.1 meters (3.6 feet). A second specimen, D2526, described in 2006, had a larger wingspan. Despite its similarities to ''Pteranodon'', ''Eopteranodon'' was not placed into a family by its describers, who put it into the clade Pteranodontia as ''incertae sedis'' (uncertain position).

Aymberedactylus Cearensis
''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.'' Discovery and naming The holotype specimen of ''Aymberedactylus'', MN 7596-V, is a nearly complete mandible preserved in three dimensions. It was discovered in the Aptian-Albian Crato Formation, a konservat-lagerstätte well known for its exquisite preservation of fossils, and it was described in 2016. The name ''Aymberedactylus'' is derived from the Tupi word ("small lizard") and Greek ("finger"), and the specific name refers to the Brazilian state of Ceará, which it was discovered in. Description ''Aymberedactylus'' can be identified as a tapejarine tapejarid Tapejaridae (from a Tupi word meaning "the old being") are a family of pterodactyloid pterosaurs from the Cretaceous period.

Caupedactylus Ybaka
''Caupedactylus'' is an extinct genus of tapejarid azhdarchoid pterosaur known from the Early Cretaceous period (Albian stage) of what is now the Romualdo Formation of the Araripe Basin in northeastern Brazil. The type and only species of ''Caupedactylus'' is ''Caupedactylus ybaka''. Discovery and naming The genus was first named and described by Alexander Wilhelm Armin Kellner in 2013. The type species is ''Caupedactylus ybaka''. The generic name combines the goddess of beauty of the Tupi, Caupe, with a Greek δάκτυλος, ''daktylos'', "finger", a usual suffix in the names of pterosaurs. The specific name ''ybaka'' means "dwelling in the sky" in the local Tupinambá. ''Caupedactylus'' is known from the holotype specimen MN 4726-V, probably found in the Araripe basin in a layer of the Romualdo Formation dating from the Albian, about 110 million years old. It consists of a partial skeleton with a complete skull, lower jaws and a partial postcranial skeleton. The postc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tupuxuara Leonardii
''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).

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 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 w ... [...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 relate ...

Keresdrakon Vilsoni
''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 Say ...
