Deterioration and/or cyclicity? The development of vegetation and climate during the Eocene and Oligocene in Antarctica
Summary The late Eocene to early Oligocene is a time interval in earth history with major changes in both the global environment and the biota. To understand the vegetation history of this time, ODP and "Islas Orcadas " core samples from the Antarctic Peninsula area and the Tasman Sea were...
