Relating to a geological age or stage from the Permian period, characterized by specific rock formations and fossil assemblages.
Named after the Artinskii Beds in the Ural Mountains of Russia. The -ian suffix is standard in geological terminology for naming time periods and rock stages.
The Artinskian stage is part of the Permian period, which ended with Earth's most catastrophic extinction event when 96% of marine species died—it's like a geological warning label about how fragile life on Earth really is.
