Systematic study and stratigraphic correlation of the Grandispora complex in the Famennian of northwest and eastern Europe.

In northwest and eastern Europe different miospore zonation schemes have been erected for the Famennian rocks, and correlation of these has proved problematical. However, in both regions of Europe Grandispora taxa are common elements in the respective Famennian spore successions, and it appears these taxa may have important intra-continental correlation potential. In order to assess this potential, a C.
