What is the past? It is a time as well as a place. Acclaimed author Peter D. Ward describes the tools that contemporary scientists use to uncover facts about the past - terrain, climate, and the life forms that once inhabited this planet. Time Machines presents fascinating profiles of the deep past and the scientists who are making it come alive.

The time machine is one of the classic devices of science fiction, a source of endless wonder and inventiveness. In a book that transfers that sense of wonder and inventiveness to the realm of nonfiction, Peter Ward shows that paleontologists do indeed use time machines to probe the deep geological past, and that both the machines and the people using them come in a fantastic variety of types. Sometimes the time machine is as simple as a rock hammer or as humble as a magnifying glass; other times it is an esoteric piece of equipment such as a mass spectrometer. Always, the most important element is the imagination of the scientists willing to take the scientific and creative risks of plumbing the distant past of our planet and its great bestiary. In 10 separate essays united by this common theme, Time Machines prowls the world of steamy Mesozoic days and fetid Paleozoic nights to rediscover the grace and beauty of Earth's faraway past.

The sweeping diversity of complex life on Earth, Ward and Brownlee argue, evolved out of an extraordinary set of physical conditions and chance events that would be extremely hard to duplicatea "a "though not impossible. Many planets throughout the vastness of the Universe may be teeming with microbial life, but advancement beyond this stage is very rare.

Peter Ward, a distinguished paleontologist and author of five trade books, recreated, in dramatic and colorful language, the global environment of the end of the last great Ice Age. The last of the great woolly mammoths existed on Wrangel Island thousands of years after their extinction elsewhere on earth. Ward examines competing theories about the courses of the great extinction and considers in detail the role of human settlements on these events.

Just 12,000 years ago - at the height of the last Ice Age - saber-toothed tigers, giant ground sloths, camels, hippos and the great herds of proboscideans: giant mastodons and mammoths, extinct relatives of the elephant, roamed the land where skyscrapers now stand. Why are these splendid creatures no longer with us? This compelling book explores the reasons for these extinctions and provides a tour of mass extinctions throughout earth's history, including the great comet crash that killed off the dinosaurs. Brilliantly written, The Call of Distant Mammoths is an engaging exploration of the history of life and the importance of humanity as an evolutionary force.
