Tyrrhenian Stage

Tyrrhenian Stage

::"This is a Geological time scale article, for archaeologiy, see Etruscan civilizationThe Tyrrhenian Stage is the last faunal stage of the Pleistocene in Europe. It runs from 0.26 million (260,000) to 0.01143 million (11,430) years ago. [http://www.stratigraphy.org/geowhen/stages/Tyrrhenian.html GeoWhen Database: Tyrrhenian European Stage] ] It overlaps with the end of the Middle Pleistocene and all of the Late Pleistocene. The time period of the Tyrrhenian Stage is the same as that of the Senegalese fauna assemblage.

Definition

The end of the Tyrrhenian is defined as exactly 10,000 Carbon-14 years before the present (0.01143 +/- 0.00013 mya), which is near to the end of the Younger Dryas cold spell.

History of the definition

The Tyrrhenian Stage was first defined in 1914 by Arturo Issel [Issel, Arturo (1914) "Lembi fossilferi quaternari e recenti nella Sardegna meridionale. "Accademia Nazionale dei Lincei" 5(23): pp. 759-770;] to describe the stratigraphic section containing "Strombus" fossils originally investigated by Gignoux. [Gignoux, M. (1913) "Les formations marines pliocenes et Quaternaires de l'Ialie du sud et de la Sicilie" "Annals de l'Universite de Lyon" n.s. 36.] "Strombus bubonius" was the leading fossil.
