Founders Symposium 2003
Volcanoes, Camels & Carnivores: The Eocene/Oligocene Story
March 29 & 30, 2003

A major bollide impacts the Earth. Huge volcanic eruptions occur in western North America. Australia and Antarctica split apart. Antarctica becomes isolated from warm currents and extensive glaciations begin in the southern continent. This dramatic series of geologic events led to the greatest single drop in Cenozoic global temperature during the transition between the Eocene and Oligocene epochs. The Earth cooled from the greenhouse world to the beginnings of our modern icebox world. Marine life and land plants were greatly affected. Yet, North American mammals showed little change across this climatic transition. Our 2003 symposium featured over a dozen paleontologists and geologists and several workshops about the flora, fauna and geology of this fascinating transitional time.
