Beipiaopterus Chenianus
''Beipiaopterus'' is a genus of ctenochasmatid pterosaur from the Early Cretaceous period (Aptian stage) of what is now the Yixian Formation of the China. The genus was named in 2003 by Lü Junchang. The generic name is derived from Beipiao City in Liaoning Province and a Latinized Greek ''pteron'', "wing". The specific epithet honors paleontologist Professor Chen Peiji Chen may refer to: People *Chen (surname) (陳 / 陈), a common Chinese surname * Chen (singer) (born 1992), member of the South Korean-Chinese boy band EXO * Chen Chen (born 1989), Chinese-American poet * (), a Hebrew first name or surname: * .... The type and only species is based on holotype BPM 0002, a crushed partial skeleton of a subadult individual on a slab, missing the skull. It includes four cervical, fourteen dorsal, three sacral and nine caudal vertebrae, a complete left wing and two hind limbs. Remains of the soft parts have been preserved, including partial wing membranes, a membrane atta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Pterodaustrini
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).

Plataleorhynchus
''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.

Huanhepterus
''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, ...

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, sev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gegepterus
''Gegepterus'' is a genus of ctenochasmatid pterosaur from the Early Cretaceous period of what is now the Yixian Formation of Liaoning, China. Only one species is known, ''G. changi''. History and etymology The genus was named in 2007 by Wang Xiaolin, Alexander Kellner, Zhou Zhonge and Diogenes de Almeida Campos. The type species is ''Gegepterus changi''. The generic name is derived from Manchu ''ge ge'', the title of a princess, in reference to the dainty gracility of the specimen, and a Latinized Greek ''pteron'', "wing". The specific name honors female paleontologist Chang Meemann, who over the years established a cordial relationship between the Chinese and Brazilian authors. In 2008 Wang emended the epithet to ''changae'', but such changes are no longer allowed by the ICZN. It is known from two specimens. The first is holotype IVPP V 11981, which was in 2001 found in grey shales from the lower part of the formation (estimated at 125 million years old), near the city of B ...
