Comments: Solikamian and Sheshmian are omitted because they are substages of the now-invalid Ufimian, so Irenian and Sokian are used instead; most of the Carboniferous names appear with greatly different spellings in the USSR scale of Harland et al., and again in their global Pennsylvanian stage scale; Carboniferous substages are mapped into Western European stages to allow better binning into 10 m.y. bins
