Kimmeridgian Stage
(named after the bay and village of Kimmeridge, Dorsetshire County, Great Britain), the third stage of the Upper Jurassic. The term was introduced by the French geologist A. d’Orbigny in 1849. The type section of Jurassic deposits from southern England shows a Kimmeridgian stage of clay strata with numerous organic remains, including ammonites (Aspidoceras acantium, Aulaeostephanus eudoxus). In the USSR the Kimmeridgian stage is widely developed in the Volga Region, Western Siberia, the Crimea, the Caucasus, the Carpathians, and other regions. It is also found in a number of countries in Western Europe (Great Britain, France, and the Federal Republic of Germany). Want to thank TFD for its existence?
