Abstract
All of the Upper Carboniferous stages in the so-called ‘Heerlen Classification’, from the Chokierian to the Bolsovian, have their base stratotypes in northern England (the Westphalian D base stratotype has yet to be selected, although sites in South Wales will probably be strong contenders). Because of their importance for stabilizing the definitions of the stages, these stratotypes have a rather different status from the other sites dealt with in this volume; they were automatically selected as GCR sites and did not have to go through the normal processes of critical assessment and comparison. Most also do not fit into the network of sites used to demonstrate the Upper Carboniferous stratigraphy in the main regions of Britain (River Darwen is the main exception); in fact, it is possible that some of the sites would not have been included in the GCR coverage, if it were not for their stratotype status.
