A seminar by Ian Geary (Department of Geology, University of Otago) sharing aspects of his recently completed PhD thesis.
Sedimentary rocks from the Auckland region have revealed a wealth of important plant, fungus and animal fossils from the Late Pliocene (c. Waipipian, 3.7–3.0 Ma) and Pleistocene (c. >Nukumaruan, 2.4–1.63 Ma). Specimens such as mosses, leaves, fruits, wood, bracket fungi and arthropods are often well preserved, taxonomically diverse and include types rarely found fossil elsewhere. The Pleistocene floras preserve many taxa which closely resemble modern New Zealand species. This is in stark contrast to the Pliocene floras, which are dominated by locally-extinct groups, such as Nothofagus subgenus Brassospora, Menispermaceae and Vitaceae. These fossils increase our understanding of the biotic, geologic and climatic history of the Auckland region during a period of changing climates.
