Simosaurus
''Simosaurus'' is an extinct genus of marine reptile within the superorder Sauropterygia from the Middle Triassic of central Europe. Fossils have been found in deposits in France and Germany that are roughly 230 million years old. It is usually classified as a nothosaur, but has also been considered a pachypleurosaur or a more primitive form of sauropterygian. Description ''Simosaurus'' grew from in length. It has a blunt, flattened head and large openings behind its eyes called upper temporal fossae. These fossae are larger than the eye sockets but not as big as those of other nothosaurs. ''Simosaurus'' also differs from other nothosaurs in that it has blunt teeth that were probably used for crushing hard-shelled organisms. The jaw joint is set far back, projecting beyond the main portion of the skull. History The type species of ''Simosaurus'', ''S. gaillardoti'', was named by German paleontologist Christian Erich Hermann von Meyer in 1842. In the same year, von Meyer also ...

Neusticosaurus
''Neusticosaurus'' (sometimes misspelled ''Neuticosaurus'') ("swimming lizard"), is an extinct genus of marine reptile belonging to the pachypleurosaurs, from Italy, Switzerland and Germany. ''Neusticosaurus'' was one of the smallest nothosaurs and probably fed on small fish Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% .... References *Seeley, H.G. (1882).

Nothosaurus
''Nothosaurus'' ("false lizard", from the Ancient Greek (), "illegitimate", and (), "lizard") is an extinct genus of sauropterygian reptile from the Triassic period, approximately 240–210 million years ago, with fossils being distributed from North Africa and Europe to China. It is the best known member of the nothosaur order. Description ''Nothosaurus'' was a semi-oceanic animal which probably had a lifestyle similar to that of today's seals. It was about , with long, webbed toes and possibly a fin on its tail. However, some species such as ''N. zhangi'' and ''N. giganteus'' were larger, up to . When swimming, ''Nothosaurus'' would use its tail, legs, and webbed feet to propel and steer it through the water. The skull was broad and flat, with long jaws, lined with needle teeth, it probably caught fish and other marine creatures. Trackways attributed, partly by process of elimination, to a nothosaur, that were reported from Yunnan, China in June 2014, were interpreted as t ...

Sauropterygia
Sauropterygia ("lizard flippers") is an extinct taxon of diverse, aquatic reptiles that developed from terrestrial ancestors soon after the end-Permian extinction and flourished during the Triassic before all except for the Plesiosauria became extinct at the end of that period. The plesiosaurs would continue to diversify until the end of the Mesozoic. Sauropterygians are united by a radical adaptation of their pectoral girdle, adapted to support powerful flipper strokes. Some later sauropterygians, such as the pliosaurs, developed a similar mechanism in their pelvis. Uniquely among reptiles, sauropterygians moved their tail vertically like modern cetaceans and sirenians. Origins and evolution The earliest sauropterygians appeared about 247 million years ago (Ma), at the start of the Middle Triassic: the first definite sauropterygian with exact stratigraphic datum lies within the Spathian division of the Olenekian era in South China. Early examples were small (around 60 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Triassic
In the geologic timescale, the Middle Triassic is the second of three epochs of the Triassic period or the middle of three series in which the Triassic system is divided in chronostratigraphy. The Middle Triassic spans the time between Ma and Ma (million years ago). It is preceded by the Early Triassic Epoch and followed by the Late Triassic Epoch. The Middle Triassic is divided into the Anisian and Ladinian ages or stages. Formerly the middle series in the Triassic was also known as Muschelkalk. This name is now only used for a specific unit of rock strata with approximately Middle Triassic age, found in western Europe. Middle Triassic fauna Following the Permian–Triassic extinction event, the most devastating of all mass-extinctions, life recovered slowly. In the Middle Triassic, many groups of organisms reached higher diversity again, such as the marine reptiles (e.g. ichthyosaurs, sauropterygians, thallatosaurs), ray-finned fish and many invertebrate g ...

Neotype
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost ...

Württemberg
Württemberg ( ; ) is a historical German territory roughly corresponding to the cultural and linguistic region of Swabia. The main town of the region is Stuttgart. Together with Baden and Hohenzollern, two other historical territories, Württemberg now forms the Federal State of Baden-Württemberg. Württemberg was formerly also spelled Würtemberg and Wirtemberg. History Originally part of the old Duchy of Swabia, its history can be summarized in the following periods: * County of Württemberg (1083–1495) * Duchy of Württemberg (1495–1803) * Electorate of Württemberg (1803–1806) * Kingdom of Württemberg (1806–1918) * Free People's State of Württemberg (1918–1945) After World War II, it was split into Württemberg-Baden and Württemberg-Hohenzollern due to the different occupation zones of the United States and France. Finally, in 1952, it was integrated into Baden-Württemberg Baden-Württemberg (; ), commonly shortened to BW or BaWü, is a German ...

Duke William Of Württemberg
Duke William of Württemberg (german: Wilhelm Nikolaus Herzog von Württemberg; 20 July 1828 – 5 November 1896) was an Austrian and Württemberg General. Early life and family Duke William was born at Carlsruhe, Kingdom of Prussia (now Pokój, Poland) was the first child of Duke Eugen of Württemberg (1788–1857, son of Duke Eugen of Württemberg and Princess Louise of Stolberg-Gedern) by his second marriage to Princess Helene of Hohenlohe-Langenburg (1807–1880, daughter of Charles Louis, Prince of Hohenlohe-Langenburg and Countess Amalie Henriette of Solms-Baruth). William had three half-siblings by his father's previous marriage with Princess Mathilde of Waldeck and Pyrmont. He was the first member of the House of Württemberg to attend a public high school in Breslau. Military career War service After studying in Geneva and Bonn, he joined the Austrian Army in 1848 as a lieutenant for Infantry Regiment Kaiser Franz Joseph No. 1 in Vienna. During the Fi ...

Ceratites
''Ceratites'' is an extinct genus of ammonite cephalopods. These nektonic carnivores lived in marine habitats in what is now Europe, during the Triassic, from the upper-most Anisian to the lower 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) ... age.Sepkoski, JacSepkoski's Online Genus Database – Cephalopoda/ref> Description This ammonite has a ceratitic suture pattern on its shell (smooth lobes and frilly saddles). Evolution of the frilly saddles is thought to be due to increased pressure on the shell, at greater depth. The frilly pattern would increase the strength of the shell and allow ''Ceratites'' to dive deeper, possibly in search of food. Distribution Fossils of this genus are only known from the Germanic Basin, which formed a partially isolated shallow sea acro ...

Keuper
The Keuper is a lithostratigraphic unit (a sequence of rock strata) in the subsurface of large parts of west and central Europe. The Keuper consists of dolomite, shales or claystones and evaporites that were deposited during the Middle and Late Triassic epochs (about ). The Keuper lies on top of the Muschelkalk and under the predominantly Lower Jurassic Lias or other Early Jurassic strata. The Keuper together with the Muschelkalk and the Buntsandstein form the Germanic Trias Group, a characteristic sequence of rock strata that gave the Triassic its name. "Muschelkalk (geology)", Britannica Online Encyclopedia, October 2010, webpage: EB-39 Exposure The Upper Triassic is well exposed in Swabia, Franconia, Alsace and Lorraine and Luxembourg; it extends from Basel on the east side of the Rhine into Hanover, and through England into Scotland and north-east Ireland; it appears flanking the central plateau of France and in the Pyrenees and Sardinia.

Ammonite
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns.
