      Originally considered as part of the «Lias» (i.e. Early Jurassic) and forming, together with the Hettangian, the so-called «Infralias». The stratotype corresponds to the Kössen Formation at Kendelbachgraben, Sankt Wolfgang, Austria.

      Before the subdivision in Olenekian and Induan became established, both stages formed the Scythian stage. It is sometimes divided into the Smithian and the Spathian substages.
