::''This is a Geological time scale article, for archaeologiy, see Etruscan civilization The Tyrrhenian Stage is the last faunal stage of the Pleistocene in Italy. It runs from 0.26 million (260,000) to 0.01143 million (11,430) years ago.〔(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.〔(Hearty, P.J. and Pra, G. Dai (2003) "Comment on: "The age of Late Pleistocene shorelines and tectonic activity of Taranto area, southern Italy" by G. Bellouomini, M. Caldara, C. Casini, M. Cerasoli, L. Manfra, G. Mastrronuzzi, G. Palmentola, P. Sanso, P. Tuccimei, and P.L. Vesica" ''Quaternary Science Reviews'' 22: pp. 2363-2367 );〕 ==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'Italie du sud et de la Sicilie" ''Annals de l'Universite de Lyon'' n.s. 36.〕 ''Strombus bubonius'' was the leading fossil.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tyrrhenian (stage)」の詳細全文を読む スポンサード リンク
