'' Artinskian of Australia. (Found near
Jimba Jimba Station ) The Artinskian is named after the goniatite grits of Artinsk which was introduced by
Roderick Murchison,
Édouard de Verneuil and count
Alexander von Keyserling in their
The Geology of Russia in Europe and the Ural Mountains (1845). The grits of Artinsk, in turn, get its name from the
Artinsky District, centered around the
Russian town of
Arti (formerly
Artinsk zavod), situated in the middle
Urals, about 170 km southwest of
Yekaterinburg. The stage was introduced into scientific literature by
Alexander Karpinsky in 1874.
Base of the Artinskian The base of the Artinskian Stage is defined as the
first appearance datum (FAD) of the
conodont species
Sweetognathus whitei and
Mesogondolella bisselli. In order to constrain this age, the ICS subcommission on Permian
stratigraphy informally proposed a candidate
GSSP in 2002, later followed by a formal proposal in 2013. The proposed GSSP location — the Dal'ny Tulkas roadcut in the
Southern Urals, near the town of
Krasnousolsky — was eventually ratified in February 2022. Earlier radiometric reported a much younger age of 280.3 Ma for the
Sakmarian-Artinskian boundary.
Top of the Artinskian The top of the Artinskian (and the base of the
Kungurian) is defined as the place in the stratigraphic record where fossils of conodonts
Neostreptognathodus pnevi and
Neostreptognathodus exculptus first appear. ==Artinskian Warming Event==
