context_page_description: In the geologic timescale, the Artinskian is an age or stage of the Permian. It is a subdivision of the Cisuralian epoch or series. The Artinskian likely lasted between 290.1 and 283.5 million years ago according to the most recent revision of the International Commission on Stratigraphy in 2013, though older versions of the ICS preferred a younger age range. It was preceded by the Sakmarian and followed by the Kungurian.
