Tsylmosuchus
''Tsylmosuchus'' is an extinct genus of potentially dubious ctenosauriscid archosauriform reptile known from Western Russia. Fossils referred to ''Tsylmosuchus'' occurred over a wide area in sediments corresponding to the Induan and Olenekian stages of the Early Triassic. Most of these fossils are fragmentary neck vertebrae which were originally reported as sharing similarities with crocodile-line archosaurs (pseudosuchians) such as ''Mandasuchus''. As a result, ''Tsylmosuchus'' was first described as part of the family Rauisuchidae, making it supposedly one of the oldest known archosaurs. However, its fragmentary remains do not show any of the distinguishing features of rauisuchids or even pseudosuchians in general, so ''Tsylmosuchus'' has more recently been interpreted as an indeterminate archosauriform. Although three species of ''Tsylmosuchus'' have been named, they lack diagnostic traits and are probably not distinct from each other. Discovery The genus is named after th ...

Rauisuchidae
Rauisuchidae is a group of large (up to or more) predatory Triassic archosaurs. There is some disagreement over which genera should be included in Rauisuchidae and which should be in the related Prestosuchidae and Poposauridae, and indeed whether these should even be thought of as separate valid families. Rauisuchids occurred throughout much of the Triassic, and may have first occurred in the Early Triassic if some archosaurian taxa such as ''Scythosuchus'' and ''Tsylmosuchus'' are considered to be within the family. An early cladistic analysis of crocodylotarsan (pseudosuchian) archosaurs included ''Lotosaurus ''Lotosaurus'' is an extinct genus of sail-backed poposauroid Poposauroidea is a clade of advanced pseudosuchians (archosaurs closer to crocodilians than to dinosaurs).

Scythosuchus
''Scythosuchus'' is an extinct genus of rauisuchid. Remains have been found from Olenekian-age Lower Triassic beds in Russia, hence the name meaning 'Scythian crocodile'. The type and only species is ''S. basileus'', described in 1999. ''Scythosuchus'' was between 2 and 3 metres long, and relatively heavily built. It is known from a partial skull, much of the spine, a fragment of the humerus and most of the hind leg and foot. It may have been the same animal as ''Tsylmosuchus''. Features Skull The skull material known is fragmentary, with a few parts of the cranium, the maxilla and some of the rostrum, and several examples of teeth. The maxilla is long, as is the preorbital fenestra just above it, and has a break indicating that there was probably a large medial process. The whole snout was slightly elongated but quite narrow. The blade-like teeth are laterally compressed and serrated, with a slight backwards curve, and would have been excellent for slicing through flesh, ...

Chasmatosuchus
''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 couldn't confidently place the species of ''Chasmatosuchus'' within Proterosuchidae. Instead their position remains 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 placed ''C. rossicus'' and ''C. magnus'' within ''Chasmatosuch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ctenosauriscidae
Ctenosauriscidae is an extinct family (biology), family of pseudosuchian archosaurs within the clade Poposauroidea. Ctenosauriscids existed in Africa, Asia, Europe and North America during the Early Triassic to the Middle Triassic period (latest Olenekian to Anisian stages). All species had large "sails" on their backs. Ctenosauriscids are among some of the earliest archosaurs and represent the first global radiation of the group. Genera Phylogeny Ctenosauriscidae was named by Oskar Kuhn in 1964 in paleontology, 1964 to include the genus ''Ctenosauriscus''. It is a stem-based taxon defined by Richard J. Butler, Stephen L. Brusatte, Mike Reich, Sterling J. Nesbitt, Rainer R. Schoch and Jahn J. Hornung in 2011 as "the most inclusive clade containing ''Ctenosauriscus koeneni'' but not ''Poposaurus gracilis'', ''Effigia okeeffeae'', ''Postosuchus kirkpatricki'', ''Crocodylus niloticus'', ''Ornithosuchus longidens'', or ''Aetosaurus ferratus''".

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between 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 Triassic span the in ...

Ustmylian Gorizont
The Ustmylian Gorizont (geology), Gorizont ("Ustmylian Horizon") is a Lower Triassic biostratigraphic unit in Western Russia. The Ustmylian Gorizont is the youngest subunit of the Vetlugian Supergorizont, lying above the Sludkian Gorizont and below the Yarenskian Gorizont. It corresponds to the later part of the early Olenekian stage. Along with the Sludkian Gorizont, the Ustmylian Gorizont is encompassed by the "''Wetlugasaurus'' fauna", named after a capitosaur amphibian index fossil. While the Sludkian is characterized by ''Wetlugasaurus angustifrons'', the Ustmylian is characterized by ''Wetlugasaurus malachovi''. The Ustmylian is exposed in several svitas (equivalent to geological formations) spread out over a wide area. These include the upper part of the Charkabozhskaya Svita (Charkabozh Formation) in the Pechora (river), Pechora Basin, the Bereznikovskaya Svita in the Moscow Syncline, the Pizhmomezen'skaya Svita near the Mezen (river), Mezen River, and the Gostevskaya Svita n ...

Proterosuchid
Proterosuchidae is an early family of basal archosauriforms whose fossils are known from the Latest Permian and the Early Triassic of Europe, Asia, Africa, Australia and possibly South America. 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, cleared the world of all large therapsids and allowed the proterosuchids to become the top predators. ...

Obshchy Syrt
Obshchy Syrt (russian: Общий Сырт) is a highland ridge, or plateau (''syrt''), in the European part of Russia. It starts north of Orenburg as a branch of the Ural Mountains and runs in a southwesterly direction to the east bank of the Volga River. River Shagan (Ural), Shagan, a tributary of the Ural (river), Ural, has its sources in the highlands. These highlands forms the Drainage divide, watershed between the rivers Volga and Ural River, Ural, and are also part of the boundary between Europe and Asia. In the eastern sector the Obshchy Syrt reaches heights of over 500 meters. The north slope of the Obshchy Syrt is covered by deciduous forests, while the southern slope towards the Caspian Depression has the characteristics of a steppe.

Komi Republic
The Komi Republic (russian: Республика Коми; kv, Коми Республика), sometimes simply referred to as Komi, is a republic of Russia located in Eastern Europe. Its capital is the city of Syktyvkar. The population of the republic as of the 2010 Census was 901,189. History The Komi people first feature in the records of the Novgorod Republic in the 12th century, when East Slavic traders from Novgorod traveled to the Perm region in search of furs and animal hides. The Komi territories came under the influence of Muscovy in the late Middle Ages (late 15th to early 16th centuries). The site of Syktyvkar, settled from the 16th century, was known as Sysolskoye (Сысольскoe). In 1780, under Catherine the Great, it was renamed to Ust-Sysolsk (Усть-Сысольск) and used as a penal colony. Russians explored the Komi territory most extensively in the 19th and early 20th centuries, starting with the expedition led by Alexander von Keyserling in ...
