FIGURE 3. Simplified composition of palynological samples (poor preparations are omitted). Raine's (1984) original distinction between a conifer-dominated Zone PM3 and a Myricipites harrissi-dominated Zone MH1 is indicated, separated by an 'interzone' in which neither are dominant. Raine's later (in Cooper 2004) distinction of a Subzone PM3b, as conifer-dominated but with Cupaneidites present, cannot be indicated on this figure. The lowest occurrence of Cupaneidites is in Kakahu-3.
