Epapatelo
''Epapatelo'' (meaning "wing") is a genus of pteranodontian pterosaur from the late Cretaceous Mocuio Formation of Namibe Province, Angola. The genus contains a single species, ''E. otyikokolo'', known from partial left limb bones. Discovery and naming Since 2005, the Projecto PaleoAngola carried out excavations at Bentiaba. For the first time in history, remains of pterosaurs were found in Angola. The recovered fossils consist of fourteen specimens of at least eleven individuals. Two of these represent the new taxon ''Epapatelo''. In 2022, the type species ''Epapatelo otyikokolo'' was named and described by Alexandra E. Fernandes, Octávio Mateus, Brian Andres, Michael J. Polcyn, Anne S. Schulp, António Olímpio, Gonçalves and Louis L. Jacobs. The scientific name is derived from Nhaneca, the language of the local nomadic population. The generic name, ''Epapatelo'', means "wing", and the specific name, ''otyikokolo'', means "lizard". The holotype, MGUAN-PA650 was foun ...

Aponyctosauria
Pteranodontia is an extinct group of ornithocheiroid pterodactyloid pterosaurs that lived during the Late Cretaceous period (Coniacian to Maastrichtian stages) of North America and Africa. They were some of the most advanced pterosaurs, and possessed highly specialized cranial crests that may have served as sexual attraction, with males having a much larger crest. Classification Pteranodontia was originally named by Marsh in 1876. In 2003, it was given a phylogenetic definition by David Unwin as the common ancestor of ''Pteranodon'' and '' Nyctosaurus'' plus all its descendants. Though Marsh had originally named this group based on the shared absence of teeth in those species, most analyses show that all of the traditional "ornithocheiroid" pterosaurs are also members of this clade. Below is a cladogram showing the phylogenetic placement of this group from Andres and Myers (2013). In 2018, Longrich, Martill, and Andres revisited the classification, and made a different ...

Nyctosauridae
Nyctosauridae (meaning "night lizards" or "bat lizards") is a family of specialized soaring pterosaurs of the late Cretaceous Period of North America, Africa, and possibly Europe. It was named in 1889 by Henry Alleyne Nicholson and Richard Lydekker.Nicholson, H.A. and Lydekker, R. (1889). ''A manual of palaeontology for the use of students: with a general introduction on the principles of palæontology, Volume II''. Blackwood, 1889. Nyctosaurids are characterized by their lack of all but the wing finger. In most pterosaurs, the hand has four fingers, with the fourth elongated to support the wing, and the remaining three are usually small, clawed, and used in walking or climbing. The lack of functional fingers in nyctosaurids may suggest that they spent almost all of their time in the air, rarely walking on the ground. Nyctosaurids also possessed a distinctively enlarged crest for muscle attachment on their upper arm bone, or humerus, the ''deltopectoral crest'', hatchet shaped l ...

Simurghia
''Simurghia'' is a genus nyctosaurid pterosaur from the Ouled Abdoun Basin of Morocco, a basin that dates to the Maastrichtian stage of the Late Cretaceous period, about 66 million years ago. It was published in 2018 by paleontologists Nicholas R. Longrich, David M. Martill, and Brian Andres, along with two other nyctosaurids from the same basin: '' Alcione'' and ''Barbaridactylus''. The type and only species is ''S. robusta''. Discovery and naming All known specimens of ''Simurghia'' were uncovered in a 3-year dig that unearthed about 200 pterosaur specimens. The type specimen, FSAC-OB 7, consists of a nearly complete humerus, lacking only the humeral head and the ulnar crest. ''Simurghia'' is named after a flying beast from Persian mythology known as the Simurgh. The species name, ''S. robusta'', is a Latin word that means "robust."

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same ta ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Cardiocorax
''Cardiocorax'' is an extinct genus of elasmosaurid known from the Late Cretaceous (early Maastrichtian stage) Mocuio Formation of Namibe Province, southern Angola. It contains a single species, ''Cardiocorax mukulu''. Its length is estimated at . Discovery ''Cardiocorax'' is known from the holotype MGUAN PA103 which consists of a complete pectoral and pelvic girdle, five neck and one back vertebrae, a partial forelimb including the humerus, radius bone, ulna and isolated phalanges, and several dorsal ribs. A second specimen was also referred to the species, MGAUN PA270, a more complete articulated pelvic girdle and a single hind limb. Both specimens are housed at the Museu de Geologia da Universidade Agostinho Neto in Luanda. The specimens were discovered at Bench 19 locality, about 7 meters from each other, in Bentiaba of the Namibe Province. They were collected from the Mocuio Formation of the Sāo Nicolau Group of Namibe Basin, dating to the early Maastricht ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plesiosaur
The Plesiosauria (; Greek: πλησίος, ''plesios'', meaning "near to" and ''sauros'', meaning "lizard") or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia. Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago. They became especially common during the Jurassic Period, thriving until their disappearance due to the Cretaceous–Paleogene extinction event at the end of the Cretaceous Period, about 66 million years ago. They had a worldwide oceanic distribution, and some species at least partly inhabited freshwater environments. Plesiosaurs were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realised how distinctive their build was and they were named as a separate order in 1835. The first plesiosaurian genus, the eponymous '' Plesiosaurus'', was named in 1821. Since then, more than a hundred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
