 Rivers in Time: The Search for Clues to Earth's Mass Extinctions by Peter D. Ward, Several times in the distant past, catastrophic extinctions have swept the Earth, causing more than half of all species -from single-celled organisms to awe-inspiring behemoths -to suddenly vanish and be replaced by new life forms. Today the rich diversity of life on the Earth is again in grave danger -and the cause is not a sudden cataclysmic event but rather humankinds devastation of the environment. Is life on our planet teetering on the brink of another mass extinction? In this absorbing new book, acclaimed paleontologist Peter D. Ward answers this daunting question with a resounding yes. Elaborating on and updating Wards previous work, "The End of Evolution," "Rivers in Time" delves into his newest discoveries. The book presents the gripping tale of the authors investigations into the history of life and death on Earth through a series of expeditions that have brought him ever closer to the truth about mass extinctions, past and future. First describing the three previous mass extinctions -those marking the transition from the Permian to the Triassic periods 245 million years ago, the Triassic to the Jurassic 200 million years ago, and the Cretaceous to the Tertiary 65 million years ago -Ward assesses the present devastation in which countless species are coming to the end of their evolution at the hand of that wandering, potentially destructive force called "Homo sapiens." The book takes readers to the Philippine Sea, now eerily empty of life, where only a few decades of catching fish by using dynamite have resulted in eviscerated coral reefs -and a dramatic reduction in the marine life the region can support. Ward travels to Canadas Queen Charlotte Islands to investigatethe extinctions that mark the boundary between the Triassic and Jurassic periods.

Undulose extinction - Undulose extinction is a geological term referring to the type of extinction that occurs in certain minerals under cross polarized light. It alters the angle of extinction across the mineral so that different parts reach extinction at slightly different angles, giving the crystal an irregular, mottled look. Ordovician-Silurian extinction events - The Ordovician-Silurian extinction event, which may have been composed of several closely spaced events, was the second largest of the five major extinction events in Earth's history in terms of percentage of genera that went extinct. The only larger one was the Permian-Triassic extinction event. Late Devonian extinction - The Late Devonian extinction was one of five major extinction events in the history of the Earth's biota. A major extinction occurred at the boundary that marks the beginning of the last phase of the Devonian period, the Famennian faunal stage, (the Frasnian-Famennian boundary), about 364 million years ago, when all the fossil agnathan fishes suddenly disappeared. Permian-Triassic extinction event - The Permian-Triassic (P-T or PT) extinction event, sometimes informally called the Great Dying, was an extinction event that occurred approximately 252 million years ago (mya), forming the boundary between the Permian and Triassic geologic periods. It was the Earth's most severe extinction event, with about 90 percent of all marine species and 70 percent of terrestrial vertebrate species going extinct.
