Tertiary have been reviewed by Hill (1994a), Macphail et al. (1994) and Jordan (1997b).
7.3.1 Constraints
Many of the larger, morphologically distinctive and/or short-ranging taxa have been formally
described over the past fifty years, e.g. by Cookson and colleagues (references in Harris
1965a, 1972, Stover and Partridge 1973, 1982). In contrast, morphologically simple
tricolpate and tricolporate angiosperm fossil pollen types usually have been ignored, even
though some of these morphotypes dominate particular assemblages. Similarly, industry
techniques designed to ‘concentrate’ rare but biostratigraphically useful taxa has meant that
the majority of small (
