Fossil pollen indicates an explosive radiation of basal Asteracean lineages and allied families during Oligocene and Miocene times in the Southern Hemisphere
Much of our knowledge of the past distribution and radiation of Asteraceae and allied families depends on the fossil pollen record. In recent years, new discoveries are coming to light from southern Africa, Australia, New Zealand, and southern South America (Patagonia). Unequivocally assigned morpho...

Much of our knowledge of the past distribution and radiation of Asteraceae and allied families depends on the fossil pollen record. In recent years, new discoveries are coming to light from southern Africa, Australia, New Zealand, and southern South America (Patagonia). Unequivocally assigned morphotaxa from accurately dated sediments have permitted for the first time a comprehensive review of the past distribution of the most important core of the sunflower alliance of families (Menyanthaceae, Goodeniaceae, Calyceraceae and Asteraceae). The main goal of this contribution is to explore the major evolutionary radiation of the basal lineages of Asteraceae (Mutisioideae and Barnadesioideae) and allied relatives (Menyanthaceae, Goodeniaceae and Calyceraceae) on the basis of the worldwide fossil pollen records. Several taxa, which today are restricted to isolated geographic regions, were widespread in the Southern Hemisphere during Paleogene times. Menyanthaceae, Goodeniaceae and Mutisioideae (Asteraceae), for example, had a wide distribution over Gondwanan landmasses in the Oligocene and are now drastically reduced in their geographic range. Early Neogene records, in contrast, suggest extinction and diversification events that progressively led to the present day configuration.
