Description
"During the greatest biodiversity crisis in the history of life some 250 million years ago, over 90% of all the species in the oceans died off in just a few hundred thousand years. Douglas Erwin, author of the new book Extinction: How Life on Earth Nearly Ended 250 Million Years Ago, discusses his research in China, South Africa, and the western U.S. in search of the causes and consequences of this great mass extinction" -- container back cover.
