Upper Devonian (Frasnian) spores from the Carnarvon basin, Western Australia

Abstract

Microfloras rich in individuals but poor in species have been separated from marine Frasnian sediments in a borehole near Carnarvon, Western Australia. These are the oldest assemblages of isolated spores yet recorded from the Southern Hemisphere. Eight species of microspores have been described, three of which are considered to be new. A new genus, Geminospora Balme, has been proposed. Comparisons may be drawn between these microfloras and Devonian assemblages from other parts of the world.
