Ornatenton Formation
The Ornatenton Formation is a Jurassic marine formation in Germany that is middle Callovian in age. The formation represents a shallow marine environment.Rauhut, Oliver W.M., Hübner, Tom R., and Lanser, Klaus-Peter, 2016, "A new megalosaurid theropod dinosaur from the late Middle Jurassic (Callovian) of north-western Germany: Implications for theropod evolution and faunal turnover in the Jurassic", ''Palaeontologia Electronica'' 19.2.26A: 1-65Mönnig, E. 1993, "Die Ornatenton-Formation in NW Deutschland."

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Gryphaea
''Gryphaea'', one of the genera known as devil's toenails, is a genus of extinct oysters, marine bivalve mollusks in the family Gryphaeidae. These fossils range from the Triassic period to the middle Paleogene period, but are mostly restricted to the Triassic and Jurassic. They are particularly common in many parts of Britain. These oysters lived on the sea bed in shallow waters, possibly in large colonies. The complete fossils consist of two articulated valves: a larger gnarly-shaped shell (the "toenail") and a smaller, flattened shell, the "lid". The soft parts of the animal occupied the cavity between the two shells, just like modern oysters. The shells also feature prominent growth bands. The larger, curved shell sat within the mud on the sea floor. These shells are sometimes found in fossil plates along with ''Turritella'', clams, and sometimes sharks' teeth and fossilized fish scales. Its distribution is common in areas of both Europe. A classic location to find thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxfordian (stage)
The Oxfordian is, in the ICS' geologic timescale, the earliest age of the Late Jurassic Epoch, or the lowest stage of the Upper Jurassic Series. It spans the time between 163.5 ± 1.0 Ma and 157.3 ± 1.0 Ma (million years ago). The Oxfordian is preceded by the Callovian and is followed by the Kimmeridgian. Stratigraphic definitions The Oxfordian Stage was called "Clunch Clay and Shale" by William Smith (1815–1816); in 1818 W. Buckland described them under the unwieldy title "Oxford, Forest or Fen Clay". The term Oxfordian was introduced by Alcide d'Orbigny in 1844. The name is derived from the English city of Oxford, where the beds are well developed, but they crop out almost continuously from Dorset to the coast of Yorkshire, generally forming low, broad valleys. They are well exposed at Weymouth, Oxford, Bedford, Peterborough, and in the cliffs at Scarborough, Red Cliff and Gristhorpe Bay. Rocks of this age are found also in Uig and Skye. The base of the Oxfordian Stage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathonian
In the geologic timescale the Bathonian is an age and stage of the Middle Jurassic. It lasted from approximately 168.3 Ma to around 166.1 Ma (million years ago). The Bathonian Age succeeds the Bajocian Age and precedes the Callovian Age. Stratigraphic definitions The Bathonian Stage takes its name from Bath, a spa town in England built on Jurassic limestone (the Latinized form of the town name is ''Bathonium''). The name was introduced in scientific literature by Belgian geologist d'Omalius d'Halloy in 1843. The original type locality was located near Bath. The French palaeontologist Alcide d'Orbigny was in 1852 the first to define the exact length of the stage. The base of the Bathonian is at the first appearance of ammonite species '' Parkinsonia (Gonolkites) convergens'' in the stratigraphic column. The global reference profile for the base of the Bathonian (a GSSP) was ratified as Ravin du Bès, Bas-Auran area, Alpes de Haute Provence, France in 2009. The top of the Bat ...

Plettenberg
Plettenberg (; Westphalian: ''Plettmert'') is a town in the Märkischer Kreis, in North Rhine-Westphalia, Germany. Geography Plettenberg is located to the west of the Sauerland hills. The highest elevation of the town area is in the ''Ebbegebirge'' with 663 m above sea level, the lowest elevation with 194 m near Teindeln. The town is spread out between the four valleys of the rivers Lenne, Else, and Grüne. Division of the town Plettenberg consists of 5 districts: * Plettenberg (town centre) (14,012 inhabitants) * Eiringhausen (4,905 inhabitants) * Holthausen/upper Elsetal (3,985 inhabitants) * Oestertal (3,055 inhabitants) * Ohle (2,825 inhabitants) History Probably the first written proof of Plettenberg was made in a document from Grafschaft Abbey of Anno II, archbishop of Cologne, at that time named ''Heslipho''. The name was later changed to Plettenberg, as the name of the noble family von Plettenberg, who owned virtually all of the town and surrounding lands. The Du ...

Swabian Jura
The Swabian Jura (german: Schwäbische Alb , more rarely ), sometimes also named Swabian Alps in English, is a mountain range in Baden-Württemberg, Germany, extending from southwest to northeast and in width. It is named after the region of Swabia. The Swabian Jura occupies the region bounded by the Danube in the southeast and the upper Neckar in the northwest. In the southwest it rises to the higher mountains of the Black Forest. The highest mountain of the region is the Lemberg (). The area's profile resembles a high plateau, which slowly falls away to the southeast. The northwestern edge is a steep escarpment (called the Albtrauf or Albanstieg, rising up , covered with forests), while the top is flat or gently rolling. In economic and cultural terms, the Swabian Jura includes regions just around the mountain range. It is a popular recreation area. Geology The geology of the Swabian Jura is mostly limestone, which formed the seabed during the Jurassic period. The sea r ...

French Alps
The French Alps are the portions of the Alps mountain range that stand within France, located in the Auvergne-Rhône-Alpes and Provence-Alpes-Côte d'Azur regions. While some of the ranges of the French Alps are entirely in France, others, such as the Mont Blanc massif, are shared with Switzerland and Italy. At , Mont Blanc (Italian: ''Monte Bianco''), on the France–Italy border, is the highest mountain in the Alps, and the highest Western European mountain. Notable towns in the French Alps include Grenoble, Chamonix, Annecy, Chambéry, Évian-les-Bains and Albertville. Ranges and summits Ski areas The largest connected ski areas are: # Les Trois Vallées (Courchevel, Méribel, La Tania, Brides-les-Bains, Saint-Martin-de-Belleville, Les Menuires, Val Thorens and Orelle): 338 slopes, 600 km of pistes. # Portes du Soleil ( Avoriaz, Châtel, Morzine, Les Gets, Saint-Jean d'Aulps, La Chapelle d'Abondance, Abondance, Montriond, Swiss resorts): 288 slopes, 650&nbs ...
