It is improbable, however, based on the combined evidence and in particular the occurrence of Notalacerta, that these strata are as young as Artinskian.
Selective disappearance and replacement of different faunal groups, especially great changes in rugose corals, have been recorded from the Late Sakmarian to Late Artinskian.
For this study several Artinskian sections were investigated in the northern part of the Central Urals, including the Most and Karpikha sections (Fig.
13]C from brachiopod shell carbonates, Ca/Mg ratio, and microfacies analyses were used to determine the ecological nature of the changes within the middle Artinskian.
Recent changes in the Artinskian part of it are shown in Fig.
1984), we could redetermine the age of the deposits in the Upper Artinskian portion (Sargian Substage) of the Most and Karpikha sections (Figs.
Two sequences are recognized in the Artinskian deposits (Fig.
The diversity of benthic and nektoplanktic fauna decreases gradually towards the Upper Artinskian turbidites formation, followed by coarse-grained clastic sediments represented by conglomerates and sandstones of terrigenous fans (Rassolnyi section, the Urals).
Taxonomic diversity of different faunal groups within the uppermost Sakmarian--lower Artinskian is well studied (Bogoslovskaya 1986; Aristov 1994; Leven et al.
The abovementioned family is specific to reefs, reef slopes, and buildups of the Asselian, Sakmarian, and Early Artinskian age.
Following the crisis, the assemblage of the rugose corals (type I of holdovers) reappears at the beginning of the Late Artinskian.
The beginning of Yachtash time (Tethys realm), corresponding approximately to the beginning of the Artinskian, shows taxonomic diversification (Leven et al.
