The Tyrrhenian Stage is the last faunal stage of the Pleistocene in Italy.
The time period of the Tyrrhenian Stage is the same as that of the Senegalese fauna assemblage.
[2] 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.
[1] The Tyrrhenian Stage was first defined in 1914 by Arturo Issel[3] to describe the stratigraphic section containing Strombus fossils originally investigated by Gignoux.
[4] Strombus bubonius was the leading fossil.
