When the The Dinosauria was first published more than a decade ago, it was hailed as "the best scholarly reference work available on dinosaurs" and "an historically unparalleled compendium of information." This second, fully revised edition continues in the same vein as the first but encompasses the recent spectacular discoveries that have continued to revolutionize the field. A state-of-the-science view of current world research, the volume includes comprehensive coverage of dinosaur systematics, reproduction, and life history strategies, biogeography, taphonomy, paleoecology, thermoregulation, and extinction. Its internationally renowned authors-forty-four specialists on the various members of the Dinosauria-contribute definitive descriptions and illustrations of these magnificent Mesozoic beasts. The first section of The Dinosauria begins with the origin of the great clade of these fascinating reptiles, followed by separate coverage of each major dinosaur taxon, including the Mesozoic radiation of birds. The second part of the volume navigates through broad areas of interest. Here we find comprehensive documentation of dinosaur distribution through time and space, discussion of the interface between geology and biology, and the paleoecological inferences that can be made through this link. Illustrations: 330 line illustrations, 28 tables

The gorgons ruled the world of animals long before there was any age of dinosaurs. They were the T. Rex of their day until an environmental cataclysm 250 million years ago annihilated them, along with 90 percent of all plant and animal species on the planet, in an event so terrible even the extinction of the dinosaurs pales in comparison. For more than a decade, Peter Ward and his colleagues have been searching in South Africa's Karoo Desert for clues to this world: What were these animals like? How did they live and, more important, how did they die?

In Gorgon, Ward examines the strange fate of this little known prehistoric animal and its contemporaries, the ancestors of the turtle, the crocodile, the lizard, and eventually dinosaurs. He offers provocative theories on these mass extinctions and confronts the startling implications they hold for us. Are we vulnerable to a similar catastrophe? Are we nearing the end of human domination in the earth's cycle of destruction and rebirth? Gorgon is also a thrilling travelogue of Ward's long, remarkable journey of discovery and a real-life adventure deep into Earth's history.
