Christian Luerssen
Christian Luerssen (6 May 1843, Bremen – 28 June 1916) was a German botanist. He was an authority in the field of pteridology. In 1872, at Leipzig, he graduated as a university teacher of botany, and was later appointed professor of botany at the Forest Academy at Neustadt-Eberswalde (1884). From 1888, he served as a professor at the University of Königsberg. After his death, a portion of his botanical collection (including European pteridophytes) was donated by Otto Bjurling to the Swedish Museum of Natural History. Luerssen was the taxonomic authority of the family Sciadopityaceae (1877). He has a number of plant species named after him, such as ''Koeleria luerssenii'' (grass species) and ''Cassia luerssenii'' (family Fabaceae). Written works * ''Filices Graeffeanae.

Emil Ernst August Tietze (15 June 1845, Breslau – 4 March 1931, Vienna) was an Austrian geologist. He received his education at the Universities of University of Breslau, Breslau and University of Tübingen, Tübingen. Afterwards, he joined the Geologische Bundesanstalt, Geological Survey of Austria (1870), an agency that Tietze would be associated with until his retirement in 1918.

Lias Group
The Lias Group or Lias is a lithostratigraphic unit (a sequence of rock strata) found in a large area of western Europe, including the British Isles, the North Sea, the Low Countries and the north of Germany. It consists of marine limestones, shales, marls and clays. ''Lias'' is a Middle English term for hard limestone, used in this specific sense by geologists since 1833. In the past, geologists used ''Lias'' not only for the sequence of rock layers, but also for the timespan during which they were formed. It was thus an alternative name for the Early Jurassic epoch of the geologic timescale. It is now more specifically known that the Lias is Rhaetian to Toarcian in age (over a period of 20 million years between ) and thus also includes a part of the Triassic. The use of the name "Lias" for a unit of time is therefore slowly disappearing. Subdivisions In southern England, the Lias Group is often divided into Lower, Middle and Upper subgroups. In Southern England the Lias is d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franconia
Franconia (german: Franken, ; Franconian dialect: ''Franggn'' ; bar, Frankn) is a region of Germany, characterised by its culture and Franconian dialect (German: ''Fränkisch''). The three administrative regions of Lower, Middle and Upper Franconia (largest cities, respectively: Würzburg, Nuremberg and Bamberg) in the State of Bavaria are part of the cultural region of Franconia, as are the adjacent Franconian-speaking South Thuringia, south of the Rennsteig ridge (largest city: Suhl), Heilbronn-Franconia (largest city: Schwäbisch Hall) in the state of Baden-Württemberg, and small parts of the state of Hesse. Those parts of the Vogtland lying in the state of Saxony (largest city: Plauen) are sometimes regarded as Franconian as well, because the Vogtlandian dialects are mostly East Franconian. The inhabitants of Saxon Vogtland, however, mostly do not consider themselves as Franconian. On the other hand, the inhabitants of the Hessian-speaking parts of Lower Franconia ...

Wiesbaden
Wiesbaden () is a city in central western Germany and the capital of the state of Hesse. , it had 290,955 inhabitants, plus approximately 21,000 United States citizens (mostly associated with the United States Army). The Wiesbaden urban area is home to approximately 560,000 people. Wiesbaden is the second-largest city in Hesse after Frankfurt, Frankfurt am Main. The city, together with nearby Frankfurt am Main, Darmstadt, and Mainz, is part of the Frankfurt Rhine Main Region, a metropolitan area with a combined population of about 5.8 million people. Wiesbaden is one of the oldest spa towns in Europe. Its name translates to "meadow baths", a reference to its famed hot springs. It is also internationally famous for its architecture and climate—it is also called the "Nice of the North" in reference to the city in France. At one time, Wiesbaden had 26 hot springs. , fourteen of the springs are still flowing. In 1970, the town hosted the tenth ''Hessentag Landesfest'' (En ...

Kassel
Kassel (; in Germany, spelled Cassel until 1926) is a city on the Fulda River in northern Hesse, Germany. It is the administrative seat of the Regierungsbezirk Kassel and the district of the same name and had 201,048 inhabitants in December 2020. The former capital of the state of Hesse-Kassel has many palaces and parks, including the Bergpark Wilhelmshöhe, which is a UNESCO World Heritage Site. Kassel is also known for the '' documenta'' exhibitions of contemporary art. Kassel has a public university with 25,000 students (2018) and a multicultural population (39% of the citizens in 2017 had a migration background). History Kassel was first mentioned in 913 AD, as the place where two deeds were signed by King Conrad I. The place was called ''Chasella'' or ''Chassalla'' and was a fortification at a bridge crossing the Fulda river. There are several yet unproven assumptions of the name's origin. It could be derived from the ancient ''Castellum Cattorum'', a castle of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhaetian
The Rhaetian is the latest age of the Triassic Period (in geochronology) or the uppermost stage of the Triassic System (in chronostratigraphy). It was preceded by the Norian and succeeded by the Hettangian (the lowermost stage or earliest age of the Jurassic). The base of the Rhaetian lacks a formal GSSP, though candidate sections include Steinbergkogel in Austria (since 2007) and Pignola-Abriola in Italy (since 2016). The end of the Rhaetian (and the base of the overlying Hettangian Stage) is more well-defined. According to the current ICS (International Commission on Stratigraphy) system, the Rhaetian ended ± 0.2 Ma (million years ago). In 2010, the base of the Rhaetian (i.e. the Norian-Rhaetian boundary) was voted to be defined based on the first appearance of '' Misikella posthernsteini'', a marine conodont. However, there is still much debate over the age of this boundary, as well as the evolution of ''M. posthernsteini''. The most comprehensive source of precise age ...

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. The Keuper sequence is li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regensburg
Regensburg or is a city in eastern Bavaria, at the confluence of the Danube, Naab and Regen rivers. It is capital of the Upper Palatinate subregion of the state in the south of Germany. With more than 150,000 inhabitants, Regensburg is the fourth-largest city in the State of Bavaria after Munich, Nuremberg and Augsburg. From its foundation as an imperial Roman river fort, the city has been the political, economic and cultural centre of the surrounding region; it is still known in the Romance languages by a cognate of its Latin name of "Ratisbona" (the version "Ratisbon" was long current in English). Later, under the rule of the Holy Roman Empire, it housed the Perpetual Diet of Regensburg. The medieval centre of the city was made a UNESCO World Heritage Site in 2006 because of its well-preserved architecture and the city's historical importance for assemblies during the Holy Roman Empire. In 2014, Regensburg was among the top sights and travel attractions in Germany. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
