Thanetian First Appearances
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
