Jaxtasuchus
''Jaxtasuchus'' is an extinct genus of armored doswelliid archosauriform reptile known from the Middle Triassic (Ladinian stage) of the Erfurt Formation in Germany. The type species, ''Jaxtasuchus salomoni'', was named in 2013 on the basis of several incomplete skeletons and other isolated remains. Like other doswelliids, members of the genus were heavily armored, with four longitudinal rows of bony plates called osteoderms covering the body. ''Jaxtasuchus'' is the first doswelliid known from Europe and is most closely related to ''Doswellia'' from the Late Triassic of the eastern United States. However, it was not as specialized as ''Doswellia'', retaining several generalized archosauriform characteristics and having less armor. ''Jaxtasuchus'' fossils have been found in aquatic mudstones alongside fossils of temnospondyl amphibians, crustaceans, and mollusks, suggesting that ''Jaxtasuchus'' was semiaquatic like modern crocodilians.

Doswelliid
Doswelliidae is an extinct family of carnivorous archosauriform reptiles that lived in North America and Europe during the Middle to Late Triassic period. Long represented solely by the heavily-armored reptile ''Doswellia'', the family's composition has expanded since 2011, although two supposed South American doswelliids (''Archeopelta'' and ''Tarjadia'') were later redescribed as erpetosuchids. Doswelliids were not true archosaurs, but they were close relatives and some studies have considered them among the most derived non-archosaurian archosauriforms. They may have also been related to the Proterochampsidae, a South American family of crocodile-like archosauriforms. Description Doswelliids are believed to be semiaquatic carnivores similar to crocodilians in appearance, as evidenced by their short legs and eyes and nostrils which are set high on the head, though the putative member ''Scleromochlus'' has been interpreted as a frog-like hopper by one study. They had long bodi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doswellia
''Doswellia'' is an extinct genus of archosauriform from the Late Triassic of North America. It is the most notable member of the family Doswelliidae, related to the proterochampsids. ''Doswellia'' was a low and heavily built carnivore which lived during the Carnian stage of the Late Triassic. It possesses many unusual features including a wide, flattened head with narrow jaws and a box-like rib cage surrounded by many rows of bony plates. The type species ''Doswellia kaltenbachi'' was named in 1980 from fossils found within the Vinita member of the Doswell Formation (formerly known as the Falling Creek Formation) in Virginia. The formation, which is found in the Taylorsville Basin, is part of the larger Newark Supergroup. ''Doswellia'' is named after Doswell, the town from which much of the taxon's remains have been found. A second species, ''D. sixmilensis,'' was described in 2012 from the Bluewater Creek Formation of the Chinle Group in New Mexico; however, this species was sub ...

Ladinian
The Ladinian is a stage and age in the Middle Triassic series or epoch. It spans the time between Ma and ~237 Ma (million years ago). The Ladinian was preceded by the Anisian and succeeded by the Carnian (part of the Upper or Late Triassic). The Ladinian is coeval with the Falangian regional stage used in China. Stratigraphic definitions The Ladinian was established by Austrian geologist Alexander Bittner in 1892. Its name comes from the Ladin people that live in the Italian Alps (in the Dolomites, then part of Austria-Hungary). The base of the Ladinian Stage is defined as the place in the stratigraphic record where the ammonite species '' Eoprotrachyceras curionii'' first appears or the first appearance of the conodont ''Budurovignathus praehungaricus''. The global reference profile for the base (the GSSP) is at an outcrop in the river bed of the Caffaro river at Bagolino, in the province of Brescia, northern Italy.The GSSP was established by Brack ''et al.''

Zanclodon Laevis
''Zanclodon'' ("scythe tooth") is an extinct genus of archosauriform found in Middle Triassic deposits in southern Germany. Taxonomy ''Zanclodon'' was originally named ''Smilodon'' by Plieninger (1846), but this name had previously been used for the saber-toothed cat (a preoccupied name), prompting Plieninger to erect the replacement name ''Zanclodon''. It was formerly placed in the Teratosauridae, within the Theropoda, and at times, plateosaurid material was mistakenly referred to ''Zanclodon'' (see Galton 2001). The type species, ''Zanclodon laevis'', is based on a left maxilla that represents an indeterminate archosaurian. Therefore, the genus is not unambiguously identifiable.Galton, P.M. (2001).

Batrachotomus Kupferzellensis
''Batrachotomus'' is a genus of prehistoric archosaur. Fossils of this animal have been found in southern Germany and dated from the Ladinian stage of the Middle Triassic period, around 242 to 237 million years ago. ''Batrachotomus'' was described by palaeontologist David J. Gower 22 years after its discovery. The locality where ''Batrachotomus'' lived was a swampy region and the name comes from the Greek ''batrachos/βάτραχος'' (frog) and ''tome/τομή'' (cutting, slicing), which refers to its preying on the large amphibian ''Mastodonsaurus''.Gower (1999), p. 6. In contrast with sprawling reptiles, like crocodiles, this large carnivore was very agile with locomotor superiority due to its erect stance. A remarkable feature seen on its back was a row of paired, flattened bony plates. ''Batrachotomus'' was possibly an early relative of ''Postosuchus'',Gower (1999), p. 1. which lived during the dawn of the dinosaurs. Description ''Batrachotomus'' was a heavily built, ...

Pseudosuchian
Pseudosuchia is one of two major divisions of Archosauria, including living crocodilians and all archosaurs more closely related to crocodilians than to birds. Pseudosuchians are also informally known as "crocodilian-line archosaurs". Prior to 2011, the clade Pseudosuchia was often called Crurotarsi in reference to the crurotarsal ankle found in almost all members of the group, which traditionally included phytosaurs, ornithosuchids, and suchians. However, a major 2011 study of Triassic archosaur relations proposed that phytosaurs were not closely related to other traditional "crurotarsans", at least compared to "bird-line archosaurs" (Avemetatarsalians) such as pterosaurs and dinosaurs. As a result, the possession of a crurotarsal ankle was considered a plesiomorphic ("primitive") feature retained by pseudosuchians. Crurotarsi now refers to a broader group of reptiles including Pseudosuchia, Phytosauria, and Avemetatarsalia. Despite Pseudosuchia meaning "false crocodiles", the n ...

Kupferzell
Kupferzell is a small German town in the district of Hohenlohe in Baden-Württemberg, Germany named after the Kupfer river flowing through it. The largest neighbouring towns are Künzelsau (to the north) and Schwäbisch Hall (to the south). History Kupferzell was first mentioned in 1236 and as early as the 14th century, the Count of Hohenlohe owned property there. During the late Middle Ages, Kupferzell always was referred to as "Celle", with a closer localization of "uf dem Ornwaldt". It was only in the 15th century that the current name appeared after its location on the Kupfer (river). From 1721 to 1727/1729, Count Philipp Ernst had a castle built here. From 1767 until 1884 Kupferzell was the residence of the duke of Hohenlohe-Waldenburg-Schillingsfürst; after mediatization in 1806, Kupferzell became part of the Königreich Württemberg under administration of the High Office of Öhringen. On January 1, 1972, Kupferzell fused with Eschental, Feßbach, Mangoldsall, Goggen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temnospondyl
Temnospondyli (from Greek language, Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') is a diverse order (biology), order of small to giant tetrapods—often considered Labyrinthodontia, primitive amphibians—that flourished worldwide during the Carboniferous, Permian, and Triassic periods. A few species continued into the Jurassic and Cretaceous periods. Fossils have been found on every continent. During about 210 million years of evolutionary history, they adapted to a wide range of habitats, including freshwater, terrestrial, and even coastal marine environments. Their life history is well understood, with fossils known from the larval stage, metamorphosis, and maturity. Most temnospondyls were semiaquatic, although some were almost fully terrestrial, returning to the water only to breed. These temnospondyls were some of the first vertebrates fully adapted to life on land. Although temnospondyls are considered amphibians, many had cha ...
