Gallodactylid
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 by ... [...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.

Gallodactylus
''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 obli ... [...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 Moganopterina ...

Gladocephaloideus
''Gladocephaloideus'' is a genus of ctenochasmatid ctenochasmatoid pterosaur from the Early Cretaceous period (early Aptian stage) of what is now western Liaoning, China. Discovery ''Gladocephaloideus'' is known from a complete skull and partial postcranial skeleton including traces of hair-like pycnofibres. It was collected from the Jingangshan Bed of the Yixian Formation, dating to the early Aptian stage, about 121 million years ago. It was named by Lü Junchang, Ji Qiang, Wei Xuefang and Liu Yongqing in 2012 and the type species is ''Gladocephaloideus jingangshanensis''. The generic name is derived from Latin ''gladius'', "sword", and Greek κεφαλή, ''kephalè'', "head", en εἶδος, ''eidos'', "form", referring to the elongated form of the skull. The specific name refers to the provenance from the Jiangangshan. The holotype, IG-CAGS-08-07, includes the almost complete skull, the lower jaws, the front neck vertebrae and part of a hindlimb. In 2016, a second spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ardeadactylus
''Ardeadactylus'' (from ''Ardea'' – meaning "heron", and also a name of a genus of herons – and ''dactylus'', meaning "finger") is an extinct genus of ctenochasmatoid pterosaur known from the Late Jurassic Solnhofen limestone of Bavaria, southern Germany. It contains a single species, ''Ardeadactylus longicollum'', which was originally thought to be a species of ''Pterodactylus'', as ''P. longicollum''. History Only two specimens of ''Ardeadactylus'' are known to exist currently: SMNS 56603 (earlier SMNS 5802) found in 1874, a specimen from Nusplingen initially thought to belong to the species '' Pterodactylus suevicus'' (currently ''Cycnorhamphus''), and the neotype of the species, JME-SOS 2428, a specimen held at Jura Museum in Eichstätt. Other known specimens, including the holotype designated by Christian Erich Hermann von Meyer when he named the type species ''Pterodactylus longicollum'' in 1854,Meyer, C.E.H. von, 1854, "Mittheilungen an Professor Bronn: Anthracotheri ...

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 havi ...

Kepodactylus
''Kepodactylus'' is an extinct genus of ctenochasmatid pterodactyloid pterosaur from the Kimmeridgian- Tithonian-age Upper Jurassic Morrison Formation of Colorado, United States. In 1992, a team from the Denver Museum of Natural History dug up a specimen of the dinosaur ''Stegosaurus stenops'' in Garden Park, Colorado. In the quarry they also found smaller disarticulated bones from other animals, among which were those of a pterosaur new to science. In 1996, Jerald Harris and Kenneth Carpenter named the new genus. The type species is ''Kepodactylus insperatus''. The genus name is derived from Greek, ''kepos'', "garden", a reference to Garden Park and ''daktylos'', "finger", referring to the typical wing finger of pterosaurs. The specific name means "unhoped-for" in Latin, alluding to the fact that the researchers hoped to find a dinosaur, and did not expect a pterosaur. The genus is based on the holotype DMNH 21684, consisting of a cervical vertebra, humerus, several fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elanodactylus
''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 .

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.
