Target entity: Saalian Stage Context triple: [Saalian glaciation, chronostratigraphicUnitOf, Saalian Stage]
-
A.
Pridoli Epoch
The Pridoli Epoch is the final epoch of the Silurian Period, marking a transitional interval in Earth’s history just before the onset of the Devonian.
-
B.
Aquitanian Stage
The Aquitanian Stage is the earliest age of the Miocene Epoch, marking a distinct interval in Earth’s geologic time characterized by significant climatic and faunal transitions.
-
C.
Saalian glaciation
chosen
The Saalian glaciation was a major Middle Pleistocene ice age in northern Europe, during which extensive ice sheets covered large parts of the continent.
-
D.
Darriwilian Stage
The Darriwilian Stage is a division of the Ordovician Period marked by significant diversification of marine life and used globally to date and correlate Middle Ordovician rock strata.
-
E.
Asselian Stage
The Asselian Stage is the earliest stage of the Permian Period, marking the transition from the Carboniferous and characterized by distinctive marine and terrestrial fossil assemblages used for global stratigraphic correlation.
