Book Description
More than a hundred years ago, Sir Arthur Conan Doyle wrote a novel called The Lost World with the exciting premise that dinosaurs and other prehistoric beasts still ruled in South America. Little did Conan Doyle know, there were terrifying monsters in South America--they just happened to be extinct. In fact, South America has an incredible history as a land where many strange creatures evolved and died out. In his book Giants of the Lost World: Dinosaurs and Other Extinct Monsters of South America, Donald R. Prothero uncovers the real science and history behind this fascinating story. The largest animal ever discovered was the huge sauropod dinosaur Argentinosaurus, which was about 130 feet long and weighed up to 100 tons. The carnivorous predator Giganotosaurus weighed in at more than 8 tons and measured more than 47 feet long, dwarfing the T. rex in comparison. Gigantic anacondas broke reptile records; possums evolved into huge saber-toothed predators; and ground sloths grew larger than elephants in this strange, unknown land. Prothero presents the scientific details about each of these prehistoric beasts, provides a picture of the ancient landscapes they once roamed, and includes the stories of the individuals who first discovered their fossils for a captivating account of a lost world that is stranger than fiction.

Book Description
Around 210 million years ago, life on Earth experienced sweeping changes. Many archaic reptiles and mammalian predecessors became extinct and were replaced by dinosaurs, pterosaurs, crocodiles, turtles, mammals, and essentially all of the major modern vertebrate groups except the birds. This period of change, which took place over a period of approximately five to ten million years, ushered in the beginning of the 'Age of Dinosaurs,' a period that lasted 160 million years to the end of the Cretaceous 65 million years ago. In the past decade, paleontologists have come to know a great deal more about this crucial interval of time. New discoveries, ideas, and insights from scientists in many related- disciplines have created new paradigms about the beginning of the 'Age of Dinosaurs.' What were the animals that preceded the dinosaurs like? How did the dinosaurs originate, and what do we know of their early history? Was their ascent tied to evolutionary innovations, global climatic and ecological changes, or just chance factors? How do paleontologists decide about the evidence preserved in the fossil record, and what areas now require major thought and reevaluation? In this book, 31 specialists in the paleontology of this era consider these and other questions related to Late Triassic and Early Jurassic times - the beginning of the 'Age of Dinosaurs,' its fauna, flora, climate, stratigraphic relationships, and major evolutionary changes. The book is divided into sections on background, Late Triassic taxa and faunas, changes across the boundary, Early Jurassic taxa and faunas, and major macroevolutionary patterns. This comprehensive volume is richly illustrated and is intended for students and professionals in the areas of paleontology, evolutionary biology, geology, and vertebrate zoology. Introductory and summary chapters are provided to acquaint the non-specialist with the issues and the setting of this interval of time in which the ancestral components of the modem fauna, as well as the Dinosauria, first appeared to rule the Earth.

Book Description
This study identifies the fall of dinosaurs as the factor that allowed mammals to evolve into the dominant tetrapod form. It refutes the single-cause impact theory for dinosaur extinction and demonstrates that multiple factors--massive volcanic eruptions, loss of shallow seas, and extraterrestrial impact--likely led to their demise. While their avian relatives ultimately survived and thrived, terrestrial dinosaurs did not. Taking their place as the dominant land and sea tetrapods were mammals, whose radiation was explosive following nonavian dinosaur extinction. The author argues that because of dinosaurs, Mesozoic mammals changed relatively slowly for 145 million years compared to the prodigious Cenozoic radiation that followed. Finally out from under the shadow of the giant reptiles, Cenozoic mammals evolved into the forms we recognize today in a mere ten million years after dinosaur extinction.

Book Description
Over the last few decades our understanding of what Australia was like during the Mesozoic Era has changed radically. A rush of new fossil discoveries, together with cutting-edge analytical techniques, has created a much more detailed picture of ancient life and environments from the great southern continent. Giant dinosaurs, bizarre sea monsters and some of the earliest ancestors of Australia’s unique modern animals and plants all occur in rocks of Mesozoic age. Ancient geographical positioning of Australia close to the southern polar circle and mounting geological evidence for near freezing temperatures also make it one of the most unusual and globally significant sources of fossils from the age of dinosaurs. This book provides the first comprehensive overview of current research on Australian Mesozoic faunas and floras, with a balanced coverage of the many technical papers, conference abstracts and unpublished material housed in current collections. It is a primary reference for researchers in the fields of palaeontology, geology and biology, senior undergraduate and postgraduate students, secondary level teachers, as well as fossil collectors and anyone interested in natural history. Dinosaurs in Australia is fully illustrated in colour with original artworks and 12 reconstructions of key animals. It has a foreword by Tim Flannery and is the ideal book for anybody seeking to know more about Australia’s amazing age of dinosaurs.

Book Description
Few aspects of American military history have been as vigorously debated as Harry Truman's decision to use atomic bombs against Japan. In this carefully crafted volume, Michael Kort describes the wartime circumstances and thinking that form the context for the decision to use these weapons, surveys the major debates related to that decision, and provides a comprehensive collection of key primary source documents that illuminate the behavior of the United States and Japan during the closing days of World War II. Kort opens with a summary of the debate over Hiroshima as it has evolved since 1945. He then provides a historical overview of thye events in question, beginning with the decision and program to build the atomic bomb. Detailing the sequence of events leading to Japan's surrender, he revisits the decisive battles of the Pacific War and the motivations of American and Japanese leaders. Finally, Kort examines ten key issues in the discussion of Hiroshima and guides readers to relevant primary source documents, scholarly books, and articles.
