• Dragon 0 beds are just above bed 36. 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. (Trümper et al., 2019)
