Gnathosaurus
''Gnathosaurus'' (meaning "jawed lizard") is a genus of ctenochasmatid pterosaur containing two species: ''G. subulatus'', named in 1833 from the Solnhofen Limestone of Germany, and ''G. macrurus'', known from the Purbeck Limestone of the UK. Its fossil remains dated back to the Late Jurassic period. History of discovery Fragments of ''Gnathosaurus'' jaws were first discovered in 1832 in the Solnhofen limestones of southern Germany but were mistaken for a piece of teleosaurid crocodile jaw by Georg zu Münster, who first named the species ''Crocodilus multidens'' in that year. Soon afterwards, Hermann von Meyer classified the same specimen as the new genus and species ''Gnathosaurus subulatus'', a name which came to be universally used shortly thereafter. In the 1860s, scientists such as Albert Oppel compared the ''G. subulatus'' jaw fragment to contemporary pterosaurs such as ''Pterodactylus'' and ''Ctenochasma'', and concluded that it was also probably a "flying reptile" rathe ...

Pterodactylus
''Pterodactylus'' (from Greek () meaning 'winged finger') is an extinct genus of pterosaurs. It is thought to contain only a single species, ''Pterodactylus antiquus'', which was the first pterosaur to be named and identified as a flying reptile. Fossil remains of ''Pterodactylus'' have primarily been found in the Solnhofen limestone of Bavaria, Germany, which dates from the Late Jurassic period (early Tithonian stage), about 150.8 to 148.5 million years ago. More fragmentary remains of ''Pterodactylus'' have tentatively been identified from elsewhere in Europe and in Africa. ''Pterodactylus'' was a generalist carnivore that probably fed on a variety of invertebrates and vertebrates. Like all pterosaurs, ''Pterodactylus'' had wings formed by a skin and muscle membrane stretching from its elongated fourth finger to its hind limbs. It was supported internally by collagen fibres and externally by keratinous ridges. ''Pterodactylus'' was a small pterosaur compared to other famo ...

Huanhepterus Quingyangensis
''Huanhepterus'' is an extinct genus of ctenochasmatid pterodactyloid pterosaur from the Early Cretaceous period of what is now Qingyang, Gansu, China. History The genus was named by Dong Zhiming in 1982. The type species is ''Huanhepterus quingyangensis''. The genus name refers to the Huang Jian (not the Yellow River or "Huang He", but a smaller tributary of the Jinghe River in Gansu), and combines it with a Latinized Greek ''pteron'', "wing". The specific name refers to Qinyang County. ''Huanhepterus'' is based on the holotype specimen, IVPP V9070, a partial articulated skeleton consisting mostly of impressions of the left half of the body and the beak-end of the skull. The fossil was in May 1978 found in a quarry operated by the Sanshilipu-commune, when an explosion exposed a vertebra. Its force obliterated the right half of the specimen. IVPP V9070 hails from the Early Cretaceous-age Huachihuanhe Formation of the Zhidan Group. Description ''Huanhepterus'' had a long, ...

Ctenochasmatinae
Ctenochasmatidae is a group of pterosaurs within the suborder Pterodactyloidea. They are characterized by their distinctive teeth, which are thought to have been used for filter-feeding. Ctenochasmatids lived from the Late Jurassic to the Early Cretaceous periods. The earliest known ctenochasmatid remains date to the Late Jurassic Kimmeridgian age. Previously, a fossil jaw recovered from the Middle Jurassic Stonesfield Slate formation in the United Kingdom, was considered the oldest known. This specimen supposedly represented a member of the family Ctenochasmatidae,Buffetaut, E. and Jeffrey, P. (2012).

Ctenochasma
''Ctenochasma'' (meaning "comb jaw") is a genus of Late Jurassic ctenochasmatid pterosaur belonging to the suborder Pterodactyloidea. Three species are currently recognized: ''C. roemeri'' (named after Friedrich Adolph Roemer), ''C. taqueti'', and ''C. elegans''. Their fossilized remains have been found in the Solnhofen Limestone of Bavaria, Germany, the "Purbeck Group" of northeastern Germany, and the Calcaires tâchetés of eastern France. History The name ''Ctenochasma'' was coined by the German paleontologist Christian Erich Hermann von Meyer in 1852, based on a single lower jaw full of closely packed teeth which he gave the species name ''Ctenochasma roemeri''.von Meyer, C.E.H. (1852). "''Ctenochasma Roemeri''." ''Paläontographica'', 2: 82–84 & pl. 13. A second species, ''C. gracile'', was named by Oppel in 1862 based on a fragmentary skull.Oppel A. (1862).

Plataleorhynchus Streptophorodon
''Plataleorhynchus'' is a genus of ctenochasmatid pterodactyloid pterosaur from the Late Jurassic to Early Cretaceous periods (Tithonian to Berriasian stages) of what is now the Purbeck Limestone of Dorset, England. History and etymology The genus was named in 1995 by Stafford Howse and Andrew Milner. The type species is ''Plataleorhynchus streptophorodon''. The genus name is derived from ''Platalea'', the spoonbill, and Greek , "snout", in reference to the distinctive form of the front of the skull. The specific name is derived from Greek , "collared", and , "tooth", referring to the tooth form. ''Plataleorhynchus'' is based on holotype NHML R.11957 (earlier BMNH R.11957), an incomplete anterior upper jaw with teeth found in a chalkstone quarry near Langton Matravers. The fossil is present on a plate; its underside is visible. This jaw is notable because it expands to form a circular, spatula-like shape at the front, holding 22 narrow teeth that point sideways.

Aurorazhdarcho
''Aurorazhdarcho'' is an extinct genus of ctenochasmatoid pterosaur known from the Late Jurassic period (early Tithonian stage) of what is now Bavaria, southern Germany. History First discovery A specimen, originally classified as ''Pterodactylus micronyx'' (now ''Aurorazhdarcho micronyx''), was one of the earliest, if not the earliest, documented pterosaur fossil ever found. The holotype specimen of ''P. micronyx'', also known as the "Pester Exemplar", was originally part of the private fossil collection held by Archduchess Maria Anna of Austria. Evidence suggest that the Pester Exemplar was unearthed at some point between 1757, when Maria Anna was recovering from serious cases of pneumonia and tuberculosis, after which she began collecting fossils, and 1779, when the specimen was first studied by scientists. This overlaps with the possible time of discovery of the holotype specimen of ''Pterodactylus antiquus'', often considered the first pterosaur found, which was unearthe ...

Feilongus Youngi
''Feilongus'' is an extinct genus of ctenochasmatid pterodactyloid pterosaur from the Barremian–Aptian-age Lower Cretaceous Yixian Formation of Beipiao, Liaoning, China. Discovery and naming The genus was named and described in 2005 by Wang Xiaolin, Alexander Kellner, Zhou Zhonghe and Diogenes de Almeida Campos. The type species is ''Feilongus youngi''. The genus name is derived from ''Feilong'', the "flying dragon". The specific name honors the Chinese paleontologist Yang Zhongjian (C. C. Young). ''Feilongus'' is based on holotype IVPP V-12539, a skull and articulated mandible, with on the same plate the detached posterior braincase, of a subadult individual. The fossil is strongly crushed. In 2014, a second specimen, DNMHM D3068 found at Gonggao, was referred to a ''Feilongus'' sp. It consists of a skull with lower jaws and four neck vertebrae. It was a possible subadult or, despite a smaller size, adult. Description The wingspan of ''Feilongus'' was estimated by Wang ...

Elanodactylus Prolatus
''Elanodactylus'' (meaning "Kite finger") is a genus of ctenochasmatid pterodactyloid pterosaur from the Early Cretaceous period (early Aptian stage) of what is now the Yixian Formation of Liaoning, China. The genus was named in 2008 by Brian Andres and Ji Qiang. The type species is ''Elanodactylus prolatus''. The generic name is derived from the Kite genus ''Elanus'', in reference to the long wings, and Greek ''daktylos'', "finger", referring to the wing finger of pterosaurs. The specific name means "elongated" in Latin, in reference to the elongated middle cervical vertebrae. It is known from a partial postcranial skeleton, holotype NGMC 99-07-1, preserving the wings, sternum, shoulder girdle, ribs, cervical and dorsal vertebrae. It represents an adult individual. In 2010, a second adult was described, specimen LPM-R00078, also a skeleton lacking the skull. The wingspan of the holotype was about , and it is estimated to have weighed .
