Tauglboden Formation
The Tauglboden Formation is a Formation (geology), geologic formation in Salzburg, Austria. It preserves fossils dating back to the Oxfordian stage of the Jurassic Period (geology), period. The radiolarites were deposited in a deep marine environment. Fossil content The following fossils were reported from the formation:Steiger, 1992Tauglboden Formation at Fossilworks.org ;Radiolarians * Nassellaria ** ''Dibolachras, Dibolachras chandrika'' ** ''Mirifusus, Mirifusus guadalupensis'' ** ''Mirifusus, M. mediodilatatus'' ** ''Podocapsa, Podocapsa amphitreptera'' ** ''Spongocapsula, Spongocapsula palmerae'' ** ''Podobursa, Podobursa sp.'' * Polycystina ** ''Homoeoparonaella, Homoeoparonaella argolidensis'' ** ''Homoeoparonaella, H. elegans'' ** ''Orbiculiforma, Orbiculiforma mclaughlini'' * ...

Formation (stratigraphy)
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 W ...

Polycystina
The polycystines are a group of radiolarians. They include the vast majority of the fossil radiolaria, as their skeletons are abundant in marine sediments, making them one of the most common groups of microfossils. These skeletons are composed of opaline silica. In some it takes the form of relatively simple spicules, but in others it forms more elaborate lattices, such as concentric spheres with radial spines or sequences of conical chambers. Two of the orders belonging to this group are the radially-symmetrical Spumellaria, dating back to the late Cambrian period, and the bilaterally-symmetrical Nasselaria, whose origin is placed within the lower Devonian The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, w .... [...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 Stag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic Austria
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassic, t ...

Ruhpolding Formation
The Ruhpolding Formation is a sedimentary formation of the Northern Calcareous Alps deposited during the Upper Jurassic. The open marine radiolarite is very rich in silica. Definitions The Ruhpolding Formation derives its name from its type locality Ruhpolding, a commune in Upper Bavaria situated at the edge of the Northern Calcareous Alps. The type locality, situated southwest of Ruhpolding (at Gschwendlbach near ''Röthelmoos'', ''Urschlau'') is a bad choice as it doesn't show the characteristic red radiolarites found elsewhere in the Austroalpine domain but only grey to red cherty limestones. This is the reason why Gawlik (2000) suggested a new type profile with a complete development of the radiolarite at ''Mörtlbach'' northeast of Hallein. The formation is also known as Ruhpolding Radiolarite or Ruhpolding Beds. In a wider context all the radiolarites of Late Bajocian, Callovian, Oxfordian, Kimmeridgian and Early Tithonian age are reunited within the Ruhpolding Radiolar ...
