Over the past twenty years, the study of dinosaurs has transformed into a true scientific discipline. New technologies have revealed secrets locked in prehistoric bones that no one could have previously predicted. We can now work out the color of dinosaurs, the force of their bite, their top speeds, and even how they cared for their young.
Remarkable new fossil discoveries-giant sauropod dinosaur skeletons in Patagonia, dinosaurs with feathers in China, and a tiny dinosaur tail in Burmese amber-remain the lifeblood of modern paleobiology. Thanks to advances in technologies and methods, however, there has been a recent revolution in the scope of new information gleaned from such fossil finds.
In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs’ lives from their fossils-their colors, their growth, and even whether we will ever be able to bring them back to life. Benton’s account shows that, though extinct, dinosaurs are still very much a part of our world.

Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human-big breakthroughs that made whole new ways of life possible-including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air. He describes the mass extinctions, especially the Permian, which obliterated 90% of life, and he sheds light on the origins of human beings, and of the many hominids that went before us. He ends by pointing out that studying the past helps us to predict the future: what happens if the atmosphere warms by five degrees? What happens if we destroy much of the biodiversity on Earth? These things have happened before, Benton notes. We need only look to the distant past to know the future of life on Earth.

Today it is common knowledge that the dinosaurs were wiped out by a meteorite impact sixty-five million years ago that killed half of all species then living. It is far less widely understood that a much greater catastrophe took place at the end of the Permian period 251 million years ago: at least ninety percent of life on earth was destroyed.
When Life Nearly Died documents not only what happened during this gigantic mass extinction but also the recent renewal of the idea of catastrophism: the theory that changes in the earth’s crust were brought about suddenly in the past by phenomena that cannot be observed today. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accumulating, and Michael J. Benton gives his verdict at the end of the volume.
The new edition brings the study of the greatest mass extinction of all time thoroughly up-to-date. In the years since the book was originally published, hundreds of geologists and paleontologists have been investigating all aspects of how life could be driven to the brink of annihilation, and especially how life recovered afterwards, providing the foundations of modern ecosystems.
