Hongshanopterus
''Hongshanopterus'' is a genus of pterodactyloid pterosaur from the Lower Cretaceous Jiufotang Formation of Liaoning, China. The type species ''Hongshanopterus lacustris'' was in 2008 named and described by Wang Xiaolin, Diogenes de Almeida Campos, Zhou Zhonghe and Alexander Wilhelm Armin Kellner. The generic name combines a reference to the Hongshan culture in Lioaning with a Latinised Greek ''pteron'', "wing". The specific name means "of the lake" in Latin, referring to the lake deposits the fossil was found in, at Dapinfang. ''Hongshanopterus'' is based on the holotype IVPP V14582, found in a layer of the Jiufotang Formation dating from the Aptian, It consists of a skull and five neck vertebrae of a single subadult individual. The wingspan of ''Hongshanopterus'' was estimated at 1.8 to 1.9 meters. It possessed a relatively high number of teeth, about thirty-six for both upper jaws combined. The teeth were robust and had triangular crowns which were flattened from mouth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Istiodactyliformes
Ornithocheiromorpha (from Ancient Greek, meaning "bird hand form") is a group of pterosaurs within the suborder 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 .... Fossil remains of this group date back from the Early Cretaceous, Early to Late Cretaceous Period (geology), periods (Valanginian to Turonian stages), around 140 to 92.5 million years ago. Ornithocheiromorphs were discovered worldwide except Antarctica, though most genera were recovered in Europe, Asia and South America. They were the most diverse and successful pterosaurs during the Early Cretaceous, but throughout the Late Cretaceous they were replaced by better adapted and more advanced pterosaur species such the pteranodontids and azhdarchoids. The Ornithocheiromorpha was defined in 2014 by Andres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haopterus
''Haopterus'' is a genus of pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Yixian Formation of Liaoning, China. Its fossil remains dated back 124.6 million years ago. Discovery and naming It was in 2001 named by Wang Xiaolin and Lü Junchang. The type species is ''Haopterus gracilis''. The genus name honors Professor Hao Yichun and combines her name with a Latinized Greek ''pteron'', "wing". The specific name, "slender-built" in Latin, refers to the condition of the metatarsals. The genus is based on holotype IVPP V11726, a crushed fossil found in 1998 at the Sihetun-locality. The layer it was discovered in, was argon-dated at an age of 124.6 million years. It was the first Chinese pterosaur fossil preserving the skull. It consists of the front half of a subadult, including a skull, lower jaws, pectoral girdle, sternum, wings, cervical and dorsal vertebrae, partial pelvis and metatarsals.

Istiodactylidae
Istiodactylidae is a small family of pterosaurs. This family was named in 2001 after the type genus ''Istiodactylus'' was discovered not to be a member of the genus ''Ornithodesmus''. Systematics and distribution Remains of taxa that can be confidently assigned to Istiodactylidae have been found in the UK and China, in rocks dating from the Early Cretaceous period (Barremian to Aptian stage). Arbour and Currie (2011) described Canadian '' Gwawinapterus beardi'' as a member of Istiodactylidae living in the late Cretaceous (upper Campanian stage); however, Witton (2012) suggested the tooth replacement pattern in this animal does not match that of pterosaurs, suggesting that the species might be non-pterosaurian. Additional research suggested that the species was in fact a fish. The earliest known species might be ''Archaeoistiodactylus linglongtaensis'', from the Middle Jurassic of China; however, it also has been suggested that the holotype specimen of this species might actuall ...

Mimodactylidae
Mimodactylidae is a group or family of pterosaurs known from Cretaceous deposits in East Asia and the Middle East. They are phylogenetically more closely related to the Istiodactylidae than to the Ornithocheiridae or the Anhangueridae, forming the clade Istiodactyliformes together with the Istiodactylidae and ''Hongshanopterus''.Kellner, Alexander W. A.; Caldwell, Michael W.; Holgado, Borja; Vecchia, Fabio M. Dalla; Nohra, Roy; Sayão, Juliana M.; Currie, Philip J. (2019).

''Liaoxipterus'' is a genus of pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. The type species is ''Liaoxipterus brachyognathus''. The genus name is derived from the discovery locality Liaoxi and a Latinised Greek ''pteron'', "wing".

Istiodactylus Latidens
''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'' (Latin for "wide tooth"), 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. ''Istiodactylus'' was a large pterosaur; estimates of its wingspan range from . Its skull was about long, and was relatively short and broad for a pterosaur. The front of the snout was low and blunt, and bore a semicircle of 48 teeth. The triangular teet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jiufotang Formation
The Jiufotang Formation (Chinese: 九佛堂组, pinyin: ''jiǔfótáng zǔ'') is an Early Cretaceous geological formation in Chaoyang, Liaoning which has yielded fossils of feathered dinosaurs, primitive birds, pterosaurs, and other organisms (see Jehol Biota). It is a member of the Jehol group. The exact age of the Jiufotang has been debated for years, with estimates ranging from the Late Jurassic to the Early Cretaceous. New uranium-lead dates reveal the formation is deposited in the Aptian stage of the Early Cretaceous. Fossils of ''Microraptor'' and ''Jeholornis'' are from the Jiufotang. Fossil content Choristoderans Fish Mammaliamorphs Several mammaliamorph specimens have been found from the Jiufotang, but only two have been formally described and named. Ornithischians Pterosaurs Saurischians A large titanosaur is present in the formation. Enantiornithines Euornithines Misc theropods See also * Yixian Formation * List of dinosaur-bearing rock for ...
