Gorgon (English)

Scientist Peter Ward examines the great extinction that ended the Permian period 250 million years ago, presenting a compelling first-person account of his high and low points as a scientist as a parallel to the extinction itself. The author tells of his team's research on the geology and fossil records of the South African desert, reconstructing the history of gorgons, the carnivorous reptiles that preceded dinosaurs. He offers theories on the extinction in addition to full details on the cataclysmic event, which destroyed not only the gorgons, but also 90 percent of all plant and animal life on the planet. minimize
