Palynostratigraphy of the Australian Early and Middle Cretaceous

Abstract

One hundred and sixty-four dinoflagellate, thirteen acritarch, and one hundred and thirty-seven spore-pollen species occurred in two hundred and sixty samples from twenty-two sections in Australia. Seventy-nine dinoflagellate and four acritarch species require taxonomic comment; the other taxa are listed. One new dinoflagellate genus, Yalkalpodinium, is proposed. Thirteen new dinoflagellate species are proposed. The Aptian to Cenomanian marine section can be divided into nine units based on microplankton occurrences. The Neocomian to Cenomanian section can be divided into seven units on spore-pollen occurrences. The dinoflagellates and associated megafauna, foraminifera, and calcareous nannofossils provide age control. The combined palynostratigraphy facilitates better correlation across Australia.
