Abstract

The Albian spore-pollen zonation of Australia is used to date terrestrial sequences from Antarctica to New Zealand. A detailed qualitative and quantitative study of the Albian Crybelosporites striatus and Coptospora paradoxa Zones in the Gippsland Basin confirms many of the published zone indicator taxa are reliable. The first and last appearance datums can be further refined quantitatively based on the upward reduction in the abundance of seed fern produced pollen. Three subzones are defined in the C. paradoxa Zone using a combination of presence/absence range and abundance data. These are (from oldest to youngest): the Trilobosporites trioreticulosus, Pilosisporites grandis and Cicatricosi..
