Thus the English Culm measures comprise an Upper Carboniferous and a Lower Carboniferous group, while in Germany, Austria and elsewhere, as it is important to bear in mind, the Culm, or Kulm, stage is shown by its contained fossils to belong to the lower division alone.
This aspect of the Culm is found in Saxony, where there are workable coals, in Bohemia, Thuringia, the Fichtelgebirge, the Harz, where the beds are traversed by mineral veins, and in Moravia and Silesia.
Culm fossils appear in the Carnic Alps, in the Balkans and parts of Spain, also in Spitzbergen and part of New Guinea.
