[edit] Nomenclature

Added Pennsylvanian and Mississippian labels to stage names to show to which epoch stages belong; lowercased several "early" and "late" Carboniferous because early and late Carboniferous are not formal subdivisions (Early and Late Mississippian and Pennsylvanian are, however). --Geologyguy 15:50, 30 April 2006 (UTC)

Aren't these subdivisions valid only in the USA? 220.236.210.230 09:08, 5 November 2006 (UTC) Ludo

Yes, this article is highly USA-centric. Where, for instance, is the Westphalian, possibly the most significant Carboniferous epoch in terms of European economic geology! Pyrope 12:53, 11 December 2006 (UTC)

Pennsylvanian and Mississippian are the internationally designated names for the two epochs of the Carboniferous. In the USA, Pennsylvanian and Mississippian are treated as full periods, but, appropriately, Wikipedia does not and simply makes note of the US usage. In this article on Carboniferous, it is entirely appropriate to use them, correctly, as the international Epoch designations. As for Wesphalian, it is connon usage in parts of Europe, but the internationally accepted Age designations are those listed here, Bashkirian, Moscovian, etc. If someone wants to add information about the Westphalian, in terms of its value and where it fits as an informal element of the formal time scale, that would be great - but it does not belong in the listing of the formal subdivisions.
