Thanetian Life
The Thanetian is, in the ICS Geologic timescale, the latest age or uppermost stratigraphic stage of the Paleocene Epoch or Series. It spans the time between . The Thanetian is preceded by the Selandian Age and followed by the Ypresian Age (part of the Eocene). The Thanetian is sometimes referred to as the Late Paleocene. Stratigraphic definition The Thanetian was established by Swiss geologist Eugène Renevier in 1873. The Thanetian is named after the Thanet Formation, the oldest Cenozoic deposit of the London Basin, which was first identified in the area of Kent (southern England) known as the Isle of Thanet. The base of the Thanetian Stage is laid at the base of magnetic chronozone C26n. The references profile (Global Boundary Stratotype Section and Point) is in the Zumaia section (43° 18'N, 2° 16'W) at the beach of Itzurun, Pais Vasco, northern Spain. Fossils of the unicellular planktonic marine coccolithophore '' Areoligeria gippingensis'' make their first appearance at ...

Tertiary Period
The Tertiary ( ) is an obsolete Period (geology), geologic period spanning 66 million to 2.6 or 1.8 million years ago. The period began with the extinction of the non-bird, avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic, Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene, Pliocene Epoch. The Tertiary has not been recognised by the International Commission on Stratigraphy (ICS) since the late 1980s, with the timespan of the Tertiary now being split in to the earlier Paleogene and the more recent Neogene periods, though the Tertiary continues to be used in some scientific publications. Historical use of the term The term Tertiary was first used by Giovanni Arduino (geologist), Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, t ...

Selandian
The Selandian is a stage in the Paleocene. It spans the time between . It is preceded by the Danian and followed by the Thanetian. Sometimes the Paleocene is subdivided in subepochs, in which the Selandian forms the "middle Paleocene". Stratigraphic definition The Selandian was introduced in scientific literature by Danish geologist Alfred Rosenkrantz in 1924. It is named after the Danish island of Zealand ( Danish: ''Sjælland'') given its prevalence there.Selandien Den Store Danske Encyklopædi The base of the Selandian is close to the boundary between biozones NP4 ...

Pais Vasco
The Basque Country or Basque Autonomous Community (), also officially called Euskadi (), is an autonomous community in northern Spain. It includes the Basque provinces of Araba, Bizkaia, and Gipuzkoa. It surrounds two enclaves called Treviño (Burgos) and Valle de Villaverde (Cantabria). The Basque Country was granted the status of ''nationality'', attributed by the Spanish Constitution of 1978. The autonomous community is based on the Statute of Autonomy of the Basque Country, a foundational legal document providing the framework for the development of the Basque people on Southern Basque Country. Parallelly, Navarre, which narrowly rejected a joint statute of autonomy in 1932, was granted a separate chartered statute in 1982. Currently there is no official capital in the autonomous community, but the city of Vitoria-Gasteiz, in the province of Álava, is the de facto capital as the location of the Basque Parliament, the headquarters of the Basque Government, and the resid ...

Zumaia
Zumaia (, ) is a small town in the north of Spain in the Basque Country (autonomous community), Basque Country. The town has two beaches (Itzurun and Santiago), which are of interest to geologists because they are situated among the longest set of continuous rock strata in the world. These formations are termed flysch and they date from the mid-cretaceous period to the present, a time period of over 100 million years. The K–T boundary is present at the Itzurun beach, and fossils can be found, notably of ammonites. The strata stretches along a distance of about 8 km, between the beaches of Deba and Getaria, with Zumaia lying in the middle. The town is also the home-turned-museum of the painter Ignacio Zuloaga. Exhibits include works by El Greco, Diego Rivera, Rivera, Zurbarán and Francisco Goya, Goya. Across the street there is a museum of craft and hand-crafted products of Laia (tool), Laia. Within the city centre, the Basque-style Gothic church of San Pedro can be found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Boundary Stratotype Section And Point
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 mar ...

Isle Of Thanet
The Isle of Thanet () is a peninsula forming the easternmost part of Kent, England. While in the past it was separated from the mainland by the Wantsum Channel, it is no longer an island. Archaeological remains testify to its settlement in ancient times. Today, it is a tourist destination, and has an active agricultural base. Etymology The island of Thanet is mentioned as ''Tonetic'' (c. AD 150; the TON- of this form was misread as TOΛI-, hence it appears as ''Toliatis'' in the surviving manuscripts of Ptolemy); ''Tanat's'', ''Athanatos'' and ''Thanatos'' (in various copies of 3rd C AD, Solinus); ''Tanatos'' (AD 731); ''Tenid'' in 679 and ''Tenet'' (e.g. charters of AD 679, 689 and thereafter); and the Old Welsh forms ''Tanet'' and ''Danet'', found in the ''Historia Brittonum'' (c. AD 829/30) and Armes Prydein (c. AD 930). Standard reference works for English place-names (such as Eilert Ekwall's ''Concise Oxford Dictionary of English Place-Names'') state the name ''Tane ...

London Basin
The London Basin is an elongated, roughly triangular sedimentary basin approximately long which underlies London and a large area of south east England, south eastern East Anglia and the adjacent North Sea. The basin formed as a result of compressional tectonics related to the Alpine orogeny during the Palaeogene period and was mainly active between 40 and 60 million years ago. Boundaries and shape Spatial boundaries The generally accepted boundaries are the Late Cretaceous Chalk Group's escarpments of the Chilterns and Marlborough Downs to the north and the North Downs and Berkshire Downs to the south. To the south lie the Weald and Salisbury Plain and to the north is the Vale of Aylesbury. The approximate western limit is in the Marlborough area of Wiltshire. The eastern end merges with the North Sea Basin, extending on land along the north Kent coast to Reculver and up the east coast of Essex and into Suffolk, where it is overlain by Pleistocene 'Crag' deposits w ...

Cenozoic
The Cenozoic Era ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterized by the dominance of mammals, insects, birds and angiosperms (flowering plants). It is the latest of three geological eras of the Phanerozoic Eon, preceded by the Mesozoic and Paleozoic. The Cenozoic started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians ( placentals) in the Northern Hemisphere and the metatherians (marsupials, now mainly restricted to Australia and to some extent South America) in the Southern Hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that large m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eugène Renevier
Eugène Renevier (26 March 1831 – 4 May 1906) was a Swiss geologist. Biography Renevier was born in Lausanne, Switzerland on 26 March 1831, as a descendant of a noble family. After about three years of study at the polytechnical school of Stuttgart, Renevier in 1851 went to Geneva to study under F. J. Pictet. In 1854 he went to Paris to attend the lectures of Hébert and to study fossil nummulites found in the limestone of the Alps. From 1859 to 1881 he was an associate professor of geology and mineralogy, then a full professor of geology and paleontology at the Academy in Lausanne (1881–1906). In 1890 the academy attained the name and status of a university. In 1898–90 he was rector of the University of Lausanne. For many years, he also served as curator of the cantonal museum of geology (1874–1906). He is distinguished for his researches on the geology and paleontology of the Alps, on which subjects he published numerous papers in the proceedings of the scientifi ...
