base notes	NOTE: 'Standard' is perhaps a mis-nomer, because there were a LOT of changes between GTS04 and GTS2012! From Mike Melchin (Aug'11): 'As you can see, the conodont zonation is very substantially revised and refined. There are many new names and almost all zonal levels are either moved or new. This is based on recently published literature.' Partly from papers by Cramer? For example; Rexroadus nathani was basal zone in GTS04/08; but is now removed; and 'second' zone extends to base of Silurian. Conodont zonal schemes are regional in Early Silurian, but more global in Middle and Late. The Early Silurian scheme here is mainly from GTS04; but elaborated and rescaled to graptolite zones following schematic in Johnson (2006). Basal zone of Silurian assumed to be Base of Rhuddanian.				comp notes
