Flo, Sweden
Flo () is a historic parish (''socken'') in the Swedish province of Västergötland. Since 1971 it has been a part of Grästorp Municipality. Geology Flo parish is the namesake for the Floian stage, which is the second stage of the Lower Ordovician. The base of the Floian is defined at the Diabasbrottet quarry type section (GSSP) 5 km to the northwest of Flo. The base is defined in the quarry as the lowest stratigraphic occurrence of the graptolite species ''Tetragraptus approximatus ''Tetragraptus approximatus'' is a species of dichograptid graptolite belonging to the genus '' Tetragraptus''. It existed during the Floian Age ( million years ago) of the Ordovician. It is an important index fossil in biostratigraphy. Descrip ...''.

Sweden
Sweden, formally the Kingdom of Sweden, is a Nordic countries, Nordic country located on the Scandinavian Peninsula in Northern Europe. It borders Norway to the west and north, and Finland to the east. At , Sweden is the largest Nordic country by both area and population, and is the List of European countries by area, fifth-largest country in Europe. Its capital and largest city is Stockholm. Sweden has a population of 10.6 million, and a low population density of ; 88% of Swedes reside in urban areas. They are mostly in the central and southern half of the country. Sweden's urban areas together cover 1.5% of its land area. Sweden has a diverse Climate of Sweden, climate owing to the length of the country, which ranges from 55th parallel north, 55°N to 69th parallel north, 69°N. Sweden has been inhabited since Prehistoric Sweden, prehistoric times around 12,000 BC. The inhabitants emerged as the Geats () and Swedes (tribe), Swedes (), who formed part of the sea-faring peopl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Västergötland
Västergötland (), also known as West Gothland or the Latinized version Westrogothia in older literature, is one of the 25 traditional non-administrative provinces of Sweden (''landskap'' in Swedish), situated in the southwest of Sweden. Västergötland is home to Gothenburg, the second largest city in Sweden, which is situated along a short stretch of the Kattegat strait. The province is bordered by Bohuslän, Dalsland, Värmland, Närke, Östergötland, Småland and Halland, as well as the two largest Swedish lakes Vänern and Vättern. Victoria, Crown Princess of Sweden is Duchess of Västergötland. Administration The provinces of Sweden serve no administrative function. Instead, that function is served by counties of Sweden. From the 17th century up until 31 December 1997, Västergötland was divided into Skaraborg County, Älvsborg County and a minor part of Gothenburg and Bohus County. From 1 January 1998 nearly all of the province is in the newly created Väs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grästorp Municipality
Grästorp Municipality () is a municipality in Västra Götaland County in western Sweden. Its seat is located in the town of Grästorp. Grästorp Municipality is located right in the middle of Västra Götaland County, by the shores of Lake Vänern. History In the year 1900 the village Grästorp was detached from Tengene and made a market town (''köping''). The local government reform of 1952 amalgamated it with twelve surrounding municipalities (among them Tengene). The 1971 reform made the term ''köping'' obsolete, thus forming Grästorps kommun without amendment of territory. The area has been inhabited at least since the Viking Age as it contains several runestones. The runestone at the church at Sal has an inscription that reads "''Torgård satte denna sten efter Toke, sin frände''", meaning "Torgård raised this stone for Toke, his kinsman". Localities The seat Grästorp (pop. 3,000) is the only built-up locality with more than 200 inhabitants in this predominantly ...

Floian
The Floian is the second stage of the Ordovician Period. It succeeds the Tremadocian with which it forms the Lower Ordovician series. It precedes the Dapingian Stage of the Middle Ordovician. The Floian extended from to million years ago. The lower boundary is defined as the first appearance of the graptolite species '' Tetragraptus approximatus''. History and naming The base of this stage was ratified by the International Commission on Stratigraphy (ICS) in 2002. The Floian Stage is named after Flo, a village in Västergötland, southern Sweden. The name "Floan" was proposed in 2004, but the ICS adapted Floian as the official name of the stage. GSSP The GSSP of the Floian is the lower Tøyen Shale in Diabasbrottet Quarry () which is an outcrop of a shale-dominated stratigraphic succession. The lower boundary of the Floian is defined as the first appearance of '' Tetragraptus approximatus'' which is about 2.1 above the Cambrian strata. Radiometric dating has set the Tremad ...

Lower Ordovician
The Early Ordovician is the first epoch of the Ordovician period, corresponding to the Lower Ordovician series of the Ordovician system. It began after the Age 10 of the Furongian epoch of the Cambrian and lasted from to million years ago, until the Dapingian age of the Middle Ordovician. It includes Tremadocian and Floian ages. History International Commission on Stratigraphy (ICS) appointed working groups on the boundaries of the Ordovician subdivisions in 1974. The boundaries were established by the fauna of conodonts and/or graptolites. In 1995, the Subcommission on Ordovician Stratigraphy, with the support of 90% majority of voting members, adopted the division of the Ordovician system into three series: Lower, Middle and Upper. In the same year, it was decided to divide each of the three series into two global stages. ''Tetragraptus approximatus'' zone was chosen as the base of the upper stage of the Lower Ordovician by 95% of the votes. Before the adoption of the in ...

GSSP
A Global Boundary Stratotype Section and Point (GSSP), sometimes referred to as a golden spike, is an internationally agreed upon reference point on a stratigraphic section which defines the lower boundary of a stage on the geologic time scale. The effort to define GSSPs is conducted by the International Commission on Stratigraphy, a part of the International Union of Geological Sciences. Most, but not all, GSSPs are based on paleontological changes. Hence GSSPs are usually described in terms of transitions between different faunal stages, though far more faunal stages have been described than GSSPs. The GSSP definition effort commenced in 1977. As of 2024, 79 of the 101 stages that need a GSSP have a ratified GSSP. Rules A geologic section has to fulfill a set of criteria to be adapted as a GSSP by the ICS. The following list summarizes the criteria: * A GSSP has to define the lower boundary of a geologic stage. * The lower boundary has to be defined using a primary m ...

Graptolite
Graptolites are a group of colonial animals, members of the subclass Graptolithina within the class Pterobranchia. These filter-feeding organisms are known chiefly from fossils found from the Middle Cambrian ( Miaolingian, Wuliuan) through the Lower Carboniferous ( Mississippian). A possible early graptolite, ''Chaunograptus'', is known from the Middle Cambrian. Recent analyses have favored the idea that the living pterobranch '' Rhabdopleura'' represents an extant graptolite which diverged from the rest of the group in the Cambrian. Fossil graptolites and ''Rhabdopleura'' share a colony structure of interconnected zooids housed in organic tubes (theca) which have a basic structure of stacked half-rings (fuselli). Most extinct graptolites belong to two major orders: the bush-like sessile Dendroidea and the planktonic, free-floating Graptoloidea. These orders most likely evolved from encrusting pterobranchs similar to ''Rhabdopleura''. Due to their widespread abundance, pl ...

Tetragraptus Approximatus
''Tetragraptus approximatus'' is a species of dichograptid graptolite belonging to the genus '' Tetragraptus''. It existed during the Floian Age ( million years ago) of the Ordovician. It is an important index fossil in biostratigraphy. Description The general outline of each ''Tetragraptus approximatus'' colony (rhabdosome) is highly distinctive. It resembles a long narrow letter H or X. The central process (the funicle) is about long, each end bifurcating at right angles with each other. Each pair of branches (stipes) curve away sharply from the ends of the funicle then run more or less parallel with each other at a distance of apart. Each of the stipes can reach more than in length, with approximately ten cup-like structures (thecae) for every of the stipes. The thecae are tilted at a 45° angle to the axis. Taxonomy ''Tetragraptus approximatus'' is classified under the genus '' Tetragraptus'' of the family Dichograptidae. It was first described by the British paleont ...
