Travel back to the time when the mighty dinosaurs ruled the earth. The Age of Dinosaurs began about 250 million years ago. In the beginning they were quite small but over time they evolved into the varied and fascinating creatures that captivate our imaginations today. What we know about dinosaurs is evolving, too! We've learned that some dinosaurs were good parents, that dinosaurs could grow new teeth when old ones fell out, and that most dinosaurs walked on two legs. We've even discovered that birds are modern relatives of dinosaurs!

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.

This series presents favorite dinosaurs, allowing young readers to explore their favorite species in detail, learning about each dinosaur's era, life cycle, source of food, predators and defense.

To this day, dinosaurs remain a never-ending source of fascination to children, who just can't get enough of these compelling creatures. Illustrations, picturing over 60 dinosaur types (including some new discoveries that appear here for the first time in a children's book), maps, and a guide to each individual species--plus an overall introduction to fossils--tell youngsters how and why all the dinosaurs developed as they did. Answer exactly the types of question kids want to know: How big were they? What did they eat? Where did they live? What do their names mean? This lively trip back to the Age of the Dinosaurs, from its beginnings in the Triassic period to the great extinction at the end of the Cretaceous, is guided by one of the major authorities in the field, Dr. Thomas Holtz, vertebrate paleontologist at the University of Maryland, whose specialty is the study of carnivorous dinosaurs.

Brimming with details of a world before our time, Age of Dinosaurs is the perfect book for anyone interested in the evolution of dinosaurs over millions of years. Beautiful illustrations transport readers to the distant past and show what these creatures may have been like all those millennia ago.
