• In bed 6, the conodont Declinognathodus marginodosus is a cosmopolitan species that defines the homonymous biozone of latest Bashkirian to earliest Moscovian age (Fig. 15; Nemyrovska, 1999; Davydov et al., 2010; 2012). This age range for bed 6 can be limited to the latest Bashkirian (Duckmantian), as plesiomorphic features (adcarinal grooves, narrow platform and parapets) of co-occurring Neognathodus specimens suggest (Nemyrovska, 1999). A latest Bashkirian age is additionally supported by the discovery of a specimen of Gastrioceras cf. listeri (Fig. 14) in the same bed. Gastrioceras species with this conch morphology (coronate shape with angular umbilical margin and coarse ribs) are representatives of the globally applicable late Bashkirian Branneroceras-Gastrioceras genus zone (Davydov et al., 2012; Korn and Klug, 2015; Fig. 15). Concerning bed 36, the conodont species Idiognathodus praeobliquus has been reported from the Donets and Midcontinent basins, where it indicates a middle Moscovian (Bolsovian) age (Fig. 15; Nemyrovska et al., 1999; Marshall, 2010; Nemyrovska, 2017). A post-Bashkirian age for bed 36 is also indicated by juvenile Idiognathodus specimens, because their prominent rostral ridges, which reach far beyond the anterior margin of the platform, appear to be too advanced for Bashkirian Idiognathodus. A late Moscovian or even Kasimovian age for the uppermost insect-bearing strata cannot be excluded given the fact that more than 45 % of unit 3 is positioned above the uppermost sampled limestone horizon.
