Pteranodon ; from Ancient Greek πτερόν and ἀνόδων is a genus of pterosaur that included some of the largest known flying reptiles, with P. longiceps having a wingspan of over 6 m (20 ft). They lived during the late Cretaceous geological period of North America in present-day Kansas, Nebraska, Wyoming, South Dakota and Alabama. More fossil specimens of Pteranodon have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. It was an important part of the animal community in the Western Interior Seaway.
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", 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 was described in 2015 based on a supposed crest fragment, but this was later shown to be part of a turtle shell.
Eosipterus is an extinct genus of ctenochasmatid pterosaur from the Early Cretaceous period of Liaoning, China. Fossil remains of Eosipterus dated back to the Aptian stage of the Early Cretaceous, 125 million years ago.
Tapejaridae 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.
Istiodactylus is a genus of pterosaur that lived during the Early Cretaceous period, about 120 million years ago. The first fossil was discovered on the English Isle of Wight in 1887, and in 1901 became the holotype specimen of a new species, O. latidens, in the genus Ornithodesmus. This species was moved to its own genus, Istiodactylus, in 2001; this name is Greek for "sail finger". More specimens were described in 1913, and Istiodactylus was the only pterosaur known from three-dimensionally preserved fossils for much of the 20th century. In 2006, a species from China, I. sinensis, was assigned to Istiodactylus, but it has also been suggested to belong to a different genus.
Santanadactylus was a genus of pterodactyloid pterosaur from the Albian-age Romualdo Member of the Upper Cretaceous Santana Formation, of Barra do Jardim, Araripe Plateau, Ceará State, Brazil. Four species have been named, but today are no considered congeneric with each other. It was a rather large pterosaur.
The Summerville Formation is a geological formation in New Mexico, Colorado, and Utah of the Southwestern United States. It dates back to the Oxfordian stage of the Late Jurassic.
The Oncala Group is a geological formation in Spain. It dates back to the Berriasian.
The Tuchengzi Formation is a geological formation in China whose strata span the Tithonian to Berriasian ages. Dinosaur fossils, particularly footprints, have been found from the formation.
The Sundance Formation is a western North American sequence of Middle Jurassic to Upper Jurassic age Dating from the Bathonian to the Oxfordian, around 168-157 Ma, It is up to 100 metres thick and consists of marine shale, sandy shale, sandstone, and limestone deposited in the Sundance Sea, an inland sea that covered large parts of western North America during the Middle and early Late Jurassic.
The Morrison Formation is a distinctive sequence of Late Jurassic sedimentary rock that is found in the western United States, which has a wide assortment of taxa represented in its fossil record, including dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone and limestone and is light grey, greenish gray, or red. Most of the fossils occur in the green siltstone beds and lower sandstones, relics of the rivers and floodplains of the Jurassic period.
Purbeckopus is an ichnotaxon of pterosaur of the family Pteraichnidae. Considered as a nomen dubium, it lived in southern England during the Berriasian, in the Early Cretaceous. According to the fossil remains found, it is expected that it was a large pterosaur, with 6 m (19.7 ft) in wingspan.
Haenamichnus is an ichnogenus that has been attributed to azhdarchid pterosaurs. In 2002, paleontologists Koo-Geun Hwang, Min Huh, Martin Lockley, David Unwin and Joanna Wright named the type species Haenamichnus uhangriensis, based on fossil tracks they found in the Uhangri Formation of South Korea, dating to 81 to 79 million years ago during the Campanian. The largest track may have belonged to an individual reaching 10 m (33 ft) in wingspan, 3 m (9.8 ft) in height and 145 kg (320 lb) in body mass. A second species, H. gainensis, was discovered from the Haman Formation, but is now considered a bipedal crocodylomorph track reassigned to as Batrachopus cf. grandis.
The Uhangri Formation, located at the Uhangri Dinosaur Fossil Site, is a geological formation from which fossil pterosaur tracks have been recovered near Haenam-eup, Jeollanam-do, South Korea.
The Haman Formation is an Early Cretaceous geological formation in South Korea. It has been dated to the Albian, with an estimated maximum depositional age of 105.4 ± 0.4 Ma. The deposit is known for its tracks, including those of dinosaurs, pterosaurs and birds. It overlies the Silla Conglomerate which overlies the Chilgok Formation. It is laterally equivalent to the Sagog Formation.
The Hekou Group is a geological group in Gansu Province, China. It is Early Cretaceous in age. Dinosaur body fossils have also been recovered from the Hekou Group, including the iguanodont Lanzhousaurus and the titanosaurs Daxiatitan, Huanghetitan and Yongjinglong, and the nodosaur Taohelong. Fossil eggs are rare, but one oogenus, Polyclonoolithus, was discovered in the Hekou Group. The group spans the Valanginian to Albian and can be subdivided into four formations. Fossil pterosaur tracks have been recovered.
The Lastres Formation is a geological formation located in Asturias province, northwestern Spain. It is believed to have been deposited in a fluvial-dominated deltaic system.
The Aztec Sandstone is an Early Jurassic geological formation of primarily eolian sand from which fossil pterosaur tracks have been recovered. The formation is exposed in the Mojave Desert of Arizona, California and Nevada. Aztec Sandstone is named after the Aztec Tank, a lake in the Spring Mountain region of Nevada.
Faxinalipterus is a genus of ornithodiran archosaur, originally described as a pterosaur, from the Late Triassic Caturrita Formation of southern Brazil. A study from 2022 reinterpreted the fossil remains and instead suggests them to belong to a member of the Lagerpetidae, another clade of pterosauromorphs.
Maaradactylus is a genus of anhanguerid pterodactyloid pterosaur known from the Lower Cretaceous period of the Romualdo Formation of northeastern Brazil.
