From the series: Critical Moments in Paleobiology and Earth History. This volume documents a fascinating story of extinctions that occurred 40-34 million years ago. It was a pivotal moment in earth history: the first signs of the Antarctic glaciation appeared and the world underwent a transition from the warm, equable Cretaceous-Paleogene "greenhouse" to its present "icehouse" state.
