Kungurian

In the geologic timescale, the Kungurian is an age or stage of the Permian. It is the latest or upper of four subdivisions of the Cisuralian epoch or series. The Kungurian lasted between 283.5 ± 0.6 and 272.3 ± 0.5 million years ago (Ma). It was preceded by the Artinskian and followed by the Roadian. It corresponds roughly to the Leonardian stage, covering the span from 280 to 270.6 ± 0.7 Ma in the North American system.
