Chasmatosuchus Rossicus
''Chasmatosuchus'' was an archosauriform reptile from the early Triassic period of European Russia. One of the earliest described archosauriforms, it was over 2 m long and is thought to have behaved like a modern crocodile. Its mouth had two distinct features: the top of its jaw hooked downwards to aid in holding prey, and the upper palate was lined with a row of teeth—a primitive feature lost in later archosaurs.''Chasmatosuchus'' was formerly assigned to Proterosuchidae, but a 2016 cladistic analysis by Martin Ezcurra could not confidently place the species of ''Chasmatosuchus'' within Proterosuchidae. Instead their position was found to be unresolved due to the fragmentary nature of the known material, however ''Chasmatosuchus'' is more likely to be intermediate between proterosuchids and erythrosuchids and possibly closely related to '' Sarmatosuchus otschevi'' and '' Cuyosuchus huenei''. Ezcurra (2016) could only place ''C. rossicus'' and ''C. magnus'' within ''Chasmat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between 251.9 Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Trias ...

Proterosuchidae
Proterosuchidae is an early family of basal archosauriforms whose fossils are known from the Late Permian and the Early Triassic. The highest diversity of genera is known from European Russia, but fossils are also known from South Africa, India, China, Australia, Brazil and possibly Argentina. The name comes from Greek πρότερο- ("first") and σοῦχος ("crocodile"). Description They were slender, medium-sized (about long, largest specimens reached ), long-snouted and superficially crocodile-like animals, although they lacked the armoured scutes of true crocodiles, and their skeletal features are much more primitive. The limbs are short and indicate a sprawling posture, like contemporary lizards but unlike most later archosaurs. Their most characteristic feature is a distinct down-turning of the premaxilla (the front of the upper jaw, which overhangs the lower jaw). Evolutionary history The terminal Permian catastrophe, which killed off 95% of all types of life, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macrocnemus
''Macrocnemus'' is an extinct genus of archosauromorph reptile known from the Middle Triassic (Late Anisian to Ladinian) of Europe and China. ''Macrocnemus'' is a member of the Tanystropheidae family and includes three species''. Macrocnemus bassanii'', the first species to be named and described, is known from the Besano Formation and adjacent paleontological sites in the Italian and Swiss Alps. ''Macrocnemus fuyuanensis,'' on the other hand, is known from the Zhuganpo Formation in southern China. A third species, ''Macrocnemus obristi,'' is known from the Prosanto Formation of Switzerland and is characterized by gracile limbs. The name ''Macrocnemus'' is Greek for "long tibia". Description ''Macrocnemus'' is known from multiple specimens, most belonging to ''M. bassanii''. It is a small reptile measuring long. ''Macrocnemus'' possessed at least 52 or 53 caudal vertebrae. Like many other early archosauromorphs, ''Macrocnemus'' had a small and low head on the end of a thin ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junior Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, ...

Jaikosuchus
''Jaikosuchus'' is an extinct genus of proterosuchid archosauriform. It contains a single species, ''J. magnus''. Fossils have been found from European Russia that date back to the upper Olenekian stage of the Early Triassic. Discovery The genus was originally assigned as a new species of the proterosuchid ''Chasmatosuchus'' in 1979, but was later put in its own genus in 1990. It has often been described as an erythrosuchid, a rauisuchian or a basal suchian closely related to rauisuchians rather than the more traditional view of it being a more primitive archosaur. In 2016, it was synonymized again with ''Chasmatosuchus'' by Ezcurra ''et al.'', but was revived as a distinct genus by Ezcurra ''et al.'' again in a 2023 overview of proterosuchid taxonomy, who found its vertebral morphology to be distinct from that of ''Chasmatosuchus''. Both were placed in the new subfamily Chasmatosuchinae Proterosuchidae is an early family of Basal (phylogenetics), basal archosauriformes, arch ...

Gamosaurus
''Gamosaurus'' is an extinct genus of Proterosuchidae, proterosuchid Archosauriformes, archosauriform. It contains a single species, ''Gamosaurus lozovskii'', named by Vitalii Georgievich Ochev in 1979 in paleontology, 1979. Discovery and explanation It is known from the Early Triassic (latest Olenekian stage) Yarenskian Gorizont of the European section of Russia. ''Gamosaurus'' is known solely from fragmentary material collected from the a fossil assemblage called the ''Parotosuchus'' fauna of the Upper Yarenskian Gorizont, in the Gam locality in Aikino district of the Komi Republic. ''Gamosaurus'' occurs with the erythrosuchian ''Garjainia'' and with material possibly referable to the paracrocodylomorph ''Vytshegdosuchus''. It was tentatively synonymized with ''Chasmatosuchus'' in a 2016 study by Martín Ezcurra, Ezcurra ''et al.'', but was revived again as a distinct genus by Ezcurra in a 2023 in a taxonomic overview of Proterosuchidae, who found its vertebral morphology to ...

Cuyosuchus Huenei
''Cuyosuchus'' is an extinct genus of archosauriform reptile. Its fossils have been found in Late Triassic-aged rocks of the Cacheuta Formation, Cuyo Basin, Mendoza, Argentina. ''Cuyosuchus'' is based on MCNAM 2669, a partial postcranial skeleton including 26 vertebrae from all parts of the spinal column, ribs, partial pectoral girdles, part of the pelvis, upper arms and part of the lower arms, the left thigh bone and shin, pitted armor scutes, and fragments. It was described in 1961 by Osvaldo Reig and named after the Cuyo Basin; the type species is ''C. huenei'', referring to German paleontologist Friedrich von Huene.

Sarmatosuchus Otschevi
''Sarmatosuchus'' is an extinct genus of archosauriform reptile found in sediments of Middle Triassic age and known from the single species ''Sarmatosuchus otschevi''. It is one of the earliest stem-archosaur species known. The holotype and only specimen was found in lithified river deposits of the Donguz Formation exposed near the Berdyanka River, Orenburg region, Russia. 1994 "Pervyj srednetriansovyj proteroscchid iz Vostochnoy Evropy." ''Doklady Akademii Nauk'' 336:359-661 The genus was originally included in the extinct family Proterosuchidae. However, later analysis by David Gower and Andrei Sennikov, the describing author, has removed it from the Proterosuchidae and designated it a basal archosauriform Archosauriformes (Greek for 'ruling lizards', and Latin for 'form') is a clade of diapsid reptiles encompassing archosaurs and some of their close relatives.

Friedrich Von Huene
Baron Friedrich Richard von Hoyningen-Huene (22 March 1875 – 4 April 1969) was a German nobleman paleontologist who described a large number of dinosaurs, more than anyone else in 20th-century Europe. He studied a range of Permo-Carboniferous tetrapods. He worked at the collections of the institute and museum for geology and paleontology at the University of Tübingen. Biography Von Huene was born in Tübingen, Kingdom of Württemberg and came from a noble Baltic German family. He took this Baltic identity to heart and would later call his home on Zeppelinstraße (now Payerstraße) as ''Villa Baltica''. His father Johannes von Hoyningen called Huene was a Lutheran minister who had studied theology at Göttingen, Tübingen and Dorpat. His mother Alexandra Baronesse Stackelberg came from an Estonian noble family. The junior Huene was also brought up with deeply religious beliefs. He grew up in Switzerland as his father taught at Basel. He also visited Latvia as a child and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archosaurs
Archosauria () or archosaurs () is a clade of diapsid sauropsid tetrapods, with birds and crocodilians being the only extant taxon, extant representatives. Although broadly classified as reptiles, which traditionally exclude birds, the cladistics, cladistic sense of the term includes all living and extinct relatives of birds and crocodilians such as non-avian dinosaurs, pterosaurs, phytosaurs, aetosaurs and rauisuchians as well as many marine reptile#Extinct groups, Mesozoic marine reptiles. Modern paleontologists define Archosauria as a crown group that includes the most recent common ancestor of living birds and crocodilians, and all of its descendants. The base of Archosauria splits into two clades: Pseudosuchia, which includes crocodilians and their extinct relatives; and Avemetatarsalia, which includes birds and their extinct relatives (such as non-avian dinosaurs and pterosaurs). Older definitions of the group Archosauria rely on shared morphology (biology), morphological ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
