Carnian Fiddle
The Carnian (less commonly, Karnian) is the lowermost stage (stratigraphy), stage of the Upper Triassic series (stratigraphy), Series (or earliest age (geology), age of the Late Triassic Epoch (reference date), Epoch). It lasted from 237 to 227 megaannum, million years ago (Ma). The Carnian is preceded by the Ladinian and is followed by the Norian. Its boundaries are not characterized by major extinctions or biotic turnovers, but a climatic event (known as the Carnian pluvial episode characterized by substantial rainfall) occurred during the Carnian and seems to be associated with important extinctions or biotic radiations. Stratigraphic definitions The Carnian was named in 1869 by Johann August Georg Edmund Mojsisovics von Mojsvar, Mojsisovics. It is unclear if it was named after the Carnic Alps or after the Austrian region of Carinthia (state), Carinthia (''Kärnten'' in German) or after the Carnia historical region in northwestern Italy. The name, however, was first used re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alluvial Plain
An alluvial plain is a largely flat landform created by the deposition of sediment over a long period of time by one or more rivers coming from highland regions, from which alluvial soil forms. A floodplain is part of the process, being the smaller area over which the rivers flood at a particular period of time, whereas the alluvial plain is the larger area representing the region over which the floodplains have shifted over geological time. As the highlands erode due to weathering and water flow, the sediment from the hills is transported to the lower plain. Various creeks will carry the water further to a river, lake, bay, or ocean. As the sediments are deposited during flood conditions in the floodplain of a creek, the elevation of the floodplain will be raised. As this reduces the channel floodwater capacity, the creek will, over time, seek new, lower paths, forming a meander (a curving sinuous path). The leftover higher locations, typically natural levees at the margins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Hallstatt Limestone
Hallstatt ( , , ) is a small town in the district of Gmunden, in the Austrian state of Upper Austria. Situated between the southwestern shore of Hallstätter See and the steep slopes of the Dachstein massif, the town lies in the Salzkammergut region, on the national road linking Salzburg and Graz. Hallstatt is known for its production of salt, dating back to prehistoric times, and gave its name to the Hallstatt culture, the archaeological culture linked to Proto-Celtic and early Celtic people of the Early Iron Age in Europe, c. 800–450 BC. Hallstatt is at the core of the Hallstatt-Dachstein/Salzkammergut Cultural Landscape declared as one of the World Heritage Sites in Austria by UNESCO in 1997. It is an area of overtourism. History Finds at Hallstatt extend from about 1200 BC until around 500 BC, and are divided by archaeologists into four phases: Iron Age In 1846, Johann Georg Ramsauer (1795–1874) discovered a large prehistoric cemetery at the Salzberg mines ne ...

Carnia
Carnia ( fur, Cjargne or ''Cjargna''/''Cjargno'' in local variants, vec, Ciargna, german: Karnien, sl, Karnija) is a historical-geographic region in the northeastern Italian area of Friuli. Its 27 municipalities all belong to the Province of Udine, which itself is part of the autonomous Friuli-Venezia Giulia region. History The name of the region, like neighbouring Carinthia and Carniola (and quite possibly also Kras or Carso), probably derives from the Carni, a Celtic tribe who had lived for centuries in the fertile plains between the Rhine and the Danube rivers where other Celtic peoples lived. Starting from 400 BC, the demographic growth and the pressure of the Germanic peoples, originated a migratory flood towards the south. The Carni crossed the Alps via the Plöcken Pass and settled in the region which is nowadays named Carnia and in the piedmont zone of Friuli. They practiced hunting and breeding. During the hard winters the herders used to move with their cattle d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carinthia (state)
Carinthia (german: Kärnten ; sl, Koroška ) is the southernmost Austrian state, in the Eastern Alps, and is noted for its mountains and lakes. The main language is German. Its regional dialects belong to the Southern Bavarian group. Carinthian Slovene dialects, forms of a South Slavic language that predominated in the southeastern part of the region up to the first half of the 20th century, are now spoken by a small minority in the area. Carinthia's main industries are tourism, electronics, engineering, forestry, and agriculture. Name The etymology of the name "Carinthia", similar to Carnia or Carniola, has not been conclusively established. The ''Ravenna Cosmography'' (about AD 700) referred to a Slavic "Carantani" tribe as the eastern neighbours of the Bavarians. In his ''History of the Lombards'', the 8th-century chronicler Paul the Deacon mentions "Slavs in Carnuntum, which is erroneously called Carantanum" (''Carnuntum, quod corrupte vocitant Carantanum'' ...

Carnic Alps
The Carnic Alps ( it, Alpi Carniche; german: Karnische Alpen; sl, Karnijske Alpe; fur, Alps Cjargnelis) are a range of the Southern Limestone Alps in Austria and northeastern Italy. They are within Austrian East Tyrol and Carinthia, and Italian Friuli (Province of Udine) and marginally in Veneto. Etymology They are named after the Roman province of Carnia, which probably has a Celtic origin. The mountains gave their name to the stage on the geologic time scale known as Carnian, an age in the Triassic Period. Geography They extend from east to west for about between the Gail River, a tributary of the Drava and the Tagliamento, forming the border between Austria and Italy. Alpine Club classification In the Carnic Alps is the southernmost glacier in Austria, the Eiskar, nestling in the Kellerwand massif. Notable peaks Among the most important mountains of the range are: * / (2,782 m) * (2,774 m) * / (2,694 m) * / (2,689 m) * (2,603 m) * (2,586 m) ...

Carnian Pluvial Episode
The Carnian pluvial episode (CPE), often called the Carnian pluvial event, was an interval of major change in global climate synchronous with significant changes in Earth's biota both in the sea and on land. It occurred during the latter part of the Carnian Stage of the late Triassic period over an interval of perhaps 1-2 million years (approximately 234-232 million years ago), across the boundary between the Julian and Tuvalian substages of the Carnian. It represents a significant episode in the evolution and diversification of many taxa that are important today, among them some of the earliest dinosaurs (which include the ancestors of birds), lepidosaurs (ancestors of modern-day snakes and lizards), pterosaurs and true mammals. In the marine realm it saw the first appearance among the microplankton of coccoliths and dinoflagellates , with the latter linked to the rapid diversification of scleractinian corals through the establishment of symbiotic zooxanthellae. The CPE also s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norian
The Norian is a division of the Triassic Period. It has the rank of an age (geochronology) or stage (chronostratigraphy). It lasted from ~227 to million years ago. It was preceded by the Carnian and succeeded by the Rhaetian. Stratigraphic definitions The Norian was named after the Noric Alps in Austria. The stage was introduced into scientific literature by Austrian geologist Edmund Mojsisovics von Mojsvar in 1869. The Norian Stage begins at the base of the ammonite biozones of '' Klamathites macrolobatus'' and '' Stikinoceras kerri'', and at the base of the conodont biozones of '' Metapolygnathus communisti'' and '' Metapolygnathus primitius''. A global reference profile for the base (a GSSP) had in 2009 not yet been appointed. The top of the Norian (the base of the Rhaetian) is at the first appearance of ammonite species '' Cochloceras amoenum''. The base of the Rheatian is also close to the first appearance of conodont species '' Misikella spp.'' and '' Epigondolella mo ...

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.''

Megaannum
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the mean yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
