Gallodactylidae
Gallodactylidae is a group of pterosaurs within the suborder Pterodactyloidea. Gallodactylids differed from other related pterosaurs in several distinct features, including fewer than 50 teeth present only in the jaw tips, and rounded crests present on the rear portion of the skull and jaws but not near the ends of their snouts. At least some species possessed jaw flanges, possibly used to bissect hard-shelled prey. History Gallodactylidae was named to contain '' Gallodactylus'' (now usually considered a synonym of '' Cycnorhamphus'') and its closest relatives. Many subsequent studies, however, showed that ''Gallodactylus'' did not form a clade with any non-synonymous pterosaurs that were not themselves part of a different family, and so the name was often ignored. The name returned to common use with the discovery of '' Gladocephaloideus'', a Chinese pterosaur species that shared many similarities with ''Cycnorhamphus''. Among other features, the Gallodactylidae was distinguished ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ctenochasmatoidea
Ctenochasmatoidea is a group of early pterosaurs within the suborder Pterodactyloidea. Their remains are usually found in what were once coastal or lake environments. They generally had long wings, long necks, and highly specialized teeth. Evolutionary history The earliest known ctenochasmatoid 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). "A ctenochasmatid pterosaur from the Stonesfield Slate (Bathonian, Middle Jurassic) of Oxfordshire, England." ''Geological Magazine'', (advance online publication) though further examination suggested it belonged to a teleosaurid stem-crocodilian instead of a pterosaur. Ecology Most ctenochasmatoids were aquatic or semi-aquatic pterosaurs, possessing large webbed hindfeet and long to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycnorhamphus
''Cycnorhamphus'' (meaning "swan beak") is a genus of gallodactylid ctenochasmatoid pterosaur from the Late Jurassic period of France and Germany, about 152 million years ago. It is probably synonymous with the genus ''Gallodactylus''. History In 1855, a fossil in a plate of shale from the Kimmeridgian, found near Nusplingen in Württemberg, holotype GPIT "Orig. Quenstedt 1855, Taf. 1" or GPIT 80, was named ''Pterodactylus Suevicus'' by Friedrich August Quenstedt. The specific name refers to the tribal area of Suevia. Quenstedt had earlier mentioned the find in a letter to Professor Heinrich Georg Bronn, which was published in 1854. In it he used the name ''Pterodactylus Württembergicus''. In 1855 and 1858, Christian Erich Hermann von Meyer adopted this older species name but it would be forgotten afterwards. The publication in 1854 was not meant to be a nomenclatural act. According to Peter Wellnhofer, ''Pterodactylus württembergicus'' should be considered a ''nomen oblitum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normannognathus
''Normannognathus'' is a genus of pterosaur from the Kimmeridgian-age Upper Jurassic Argiles d'Octeville Formation of France. Initially, ''Normannognathus'' was classified to the family Germanodactylidae, sister taxon to ''Germanodactylus'', however, many recent analysis have recovered ''Normannognathus'' in different phylogenetic positions, and depending on different authors, ''Normannognathus'' is either found as a basal member of the Dsungaripteroidea, as an indeterminate monofenestratan, or as the sister taxon of '' Cycnorhamphus'' within the family Gallodactylidae. Discovery and naming In 1993, Jean-Jacques Lepage on the Normandy coast at the Cap de la Hève, near Ecqueville, Octeville-sur-Mer, Seine-Maritime, Normandy, found a ten centimetres long fossil of a pterosaur in a marine claystone layer. In 1998, Eric Buffetaut ''et al.'' named a separate genus for it. The type species is ''Normannognathus wellnhoferi''. The genus name is derived from ''Normannia'', the Med ...

Pterodactyloidea
Pterodactyloidea (derived from the Greek words ''πτερόν'' (''pterón'', for usual ''ptéryx'') "wing", and ''δάκτυλος'' (''dáktylos'') "finger" meaning "winged finger", "wing-finger" or "finger-wing") is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles. They appeared during the middle Jurassic Period, and differ from the basal (though paraphyletic) rhamphorhynchoids by their short tails and long wing metacarpals (hand bones). The most advanced forms also lack teeth, and by the late Cretaceous, all known pterodactyloids were toothless. Many species had well-developed crests on the skull, a form of display taken to extremes in giant-crested forms like '' Nyctosaurus'' and '' Tupandactylus''. Pterodactyloids were the last surviving pterosaurs when the order became extinct at the end of the Cretaceous Period, together with the non-avian dinosaurs and most marine reptiles. " Pter ...

Boreopterus
''Boreopterus'' is a genus of boreopterid pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Yixian Formation of Dalian, Liaoning, China. Etymology ''Boreopterus'' was named in 2005 by Lü Junchang and Ji Qiang. The type species is ''Boreopterus cuiae''. The genus name is derived from Greek ''boreios'', "northern" and ''pteron'', "wing". The specific epithet honors Cui Xu. Description ''Boreopterus'' is based on holotype JZMP-04-07-3, a nearly complete but crushed skeleton and skull. The skull is 235 millimeters long (9.25 inches), low and elongated with a rounded tip. Its wingspan is estimated to have been around 1.45 meters (4.76 feet). Its teeth, especially the anterior nine pairs, are quite large, forming a mesh of sharp teeth at the front of the mouth; the third and fourth teeth from the front are the largest. There are at least 27 teeth in each side of both the upper and lower jaws, which is a large amount. Classification Lü an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feilongus
''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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boreopteridae
Boreopteridae (meaning "northern wings") is a group of pterodactyloid pterosaurs from the Aptian-age Lower Cretaceous Yixian Formation of Liaoning, China. Classification In 2006, Lü Junchang and colleagues named the clade Boreopteridae for the clade containing the common ancestor of '' Boreopterus'' and '' Feilongus'' and all its descendants, which the authors reclassified as close relatives of the ornithocheirids. (''Feilongus'' had originally been considered a gallodactylid). Many possible boreopterids were subsequently described, one possible example being '' Aetodactylus'', which has been claimed to be similar to '' Boreopterus''. Originally considered close relatives of the ornithocheirids, many of these supposed boreopterids have been found to belong to other groups of the pterodactyloid lineage. In 2012, a phylogenetic analysis by Lü ''et al.'' divided the Boreopteridae into two subfamilies: Boreopterinae, comprising ''Boreopterus'' and ''Zhenyuanopterus'', and Mogan ...

Moganopterus
''Moganopterus'' is an extinct genus of ctenochasmatid pterosaur from the Early Cretaceous of western Liaoning Province, China. Discovery and naming The fossil of ''Moganopterus'' was discovered at the village of Xiaosanjiazi near the town of Lamadong in Liaoning Province. In 2012 it was named and described by Lü Junchang, Pu Hanyong, Xu Li, Wu Yanhua and Wei Xuefang as the type species ''Moganopterus zhuiana''. The generic name is derived from the legendary sword couple Gan Jiang and Mo Ye, in reference to the blade-like jaws, and a Latinized Greek πτερόν, ''pteron'', "wing". The specific name honors Ms. Zhu Haifen, who made the specimen available to science. The holotype, 41HIII0419, was uncovered in a layer of the Yixian Formation, dating from the Aptian, about 125 million years old. It consists of an almost complete skull with lower jaws and the second to fourth neck vertebrae. The fossil is compressed on a slab and counterslab, the splitting of the two plates ha ...
