Selenops Beynai
Selenops is a spider genus that is found in many arid regions of the world, but some species may also be found in some cooler and even mountainous regions. Most of the 132 species (as of May. 2021) are hard to visually distinguish, and requires study of their finer anatomy. ''S. australiensis'' is found on or under dry bark in Australia. The female reaches 9mm, the male 7mm. It looks superficially like a huntsman spider. ''S. radiatus'' has proved to be an effective controlling agent of the potato tuber moth in South Africa. Selenops is the first spider known to be able to steer and glide when falling, in order to land in or on a tree, instead of falling to the ground. Selenops spiders are able to attack prey approaching from all directions. When attacking prey from behind, they show some of the fastest turning movements documented in terrestrial legged animals. Name Named after the moon goddess Selene, and Greek ''-ops'' "eye", because of the moon-like form of the eyes. Sel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bull Canyon Formation
The Cooper Canyon Formation is a geological formation of Norian age in Texas and New Mexico.Weishampel, David B; et al. (2004).Dinosaur distribution (Late Triassic, North America)" In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 518–521. . Type area of the formation is situated in Garza County, Texas. An equivalent formation in eastern New Mexico is named Bull Canyon Formation. Some researchers argue that the latter name should be abandoned. The formation consist of reddish siltstone and mudstone with lenses of sandstone and conglomerate. Thickness of the formation in the type area is 161.5 meters. It increases to the south, and in some places exceeds 200 m. The formation contains diverse fossils, including vertebrate remains.

Norian
The Norian is a division of the Triassic Period. It has the rank of an age (geochronology) or stage (chronostratigraphy). It lasted from ~227 to million years ago. It was preceded by the Carnian and succeeded by the Rhaetian. Stratigraphic definitions The Norian was named after the Noric Alps in Austria. The stage was introduced into scientific literature by Austrian geologist Edmund Mojsisovics von Mojsvar in 1869. The Norian Stage begins at the base of the ammonite biozones of '' Klamathites macrolobatus'' and '' Stikinoceras kerri'', and at the base of the conodont biozones of '' Metapolygnathus communisti'' and '' Metapolygnathus primitius''. A global reference profile for the base (a GSSP) had in 2009 not yet been appointed. The top of the Norian (the base of the Rhaetian) is at the first appearance of ammonite species '' Cochloceras amoenum''. The base of the Rheatian is also close to the first appearance of conodont species '' Misikella spp.'' and '' Epigondolella mo ...

Sankar Chatterjee
Sankar Chatterjee (born May 28, 1943) is a paleontologist, and is the Paul W. Horn Professor of Geosciences at Texas Tech University and Curator of Paleontology at the Museum of Texas Tech University. He earned his Ph. D. from the University of Calcutta in 1970 and was a Post-doctoral Fellow at the Smithsonian Institution from 1977-1978. Chatterjee has focused on the origin, evolution, functional anatomy, and systematics of Mesozoic vertebrates, including basal archosaurs, dinosaurs, pterosaurs, and birds. He has researched Late Triassic reptiles in India, such as phytosaurs, rhynchosaurs, and prolacertiformes. He is best known for his work on vertebrates recovered in the 1980s from the Post Quarry in the Late Triassic Cooper Canyon Formation (Dockum Group) of West Texas. The material includes the large rauisuchian ''Postosuchus'', which was named for the nearby town of Post. It also included controversial specimens Chatterjee identified as being avian (''Protoavis''). The ident ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technosaurus
''Technosaurus'' (meaning "Tech lizard", for Texas Tech University) is an extinct genus of Late Triassic silesaurid dinosauriform, from the Late Triassic Cooper Canyon Formation (Dockum Group) of Texas, United States. For about 20 years after its description, it was thought to be a basal ornithischian dinosaur, but better remains of other Triassic archosaurs have cast doubt on this interpretation. As named, it was a chimera of different animals. Description and history ''Technosaurus'' is based on TTUP P9021, which initially consisted of a premaxilla (tip of the upper jaw), two lower jaw pieces, a back vertebra, and an astragalus. ''Technosaurus'' and its type species, ''T. smalli'', were named by Sankar Chatterjee in 1984. He described it as a fabrosaurid, a clade of small early ornithischians now considered to have been an artificial grouping. Material from the quarry where P9021 was found is disassociated and comes from a variety of Late Triassic animals, which would p ...

Alternognathus
''Alternognathus'' is an extinct conodont Conodonts (Greek ''kōnos'', "cone", + ''odont'', "tooth") are an extinct group of agnathan (jawless) vertebrates resembling eels, classified in the class Conodonta. For many years, they were known only from their tooth-like oral elements, which ... genus in the family Elictognathidae. An extensive study on its population dynamics and lifespan has recently been published.Przemysław Świś (2019). "Population dynamics of the Late Devonian conodont Alternognathus calibrated in days".

Charles A
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...

Pseudarmadillo Tuberculatus
''Pseudarmadillo tuberculatus'' is an extinct species of isopod in the family Delatorreiidae known from a series of possibly Miocene fossils found on Hispaniola. At the time of description ''P. tuberculatus'' was one of two '' Pseudarmadillo'' species known from the fossil record and one of only two from Hispaniola. History and classification ''P. tuberculatus'' is known from four isopods, both female and male, all of which are inclusions in three different transparent chunks of Dominican amber. Two of the paratypes are fossils in the same amber specimen while the other two individuals are both in separate amber specimens. The amber specimens which entomb the holotype and paratypes, are currently preserved in the Division of Invertebrate Zoology collections at the Staatliches Museum für Naturkunde Stuttgart in Stuttgart, Germany. The type specimens were collected from an undetermined amber mine, in fossil bearing rocks of the Cordillera Septentrional mountains, northern Domi ...
