Extreme Dinosaurs ventures deep into prehistory to examine a vanished world. Learn how Tyrannosaurus rex hunted and scavenged, marvel at the mountain of flesh and bone that was Argentinosaurus, and experience the trials and triumphs of paleontologists past and present. Evolving and diversifying rapidly, dinosaurs dominated the Earth for more than 150 million years. Encounter the "terrible lizards" in all their glory, whether agile pack-hunters, bony-plated beasts, or tiny hatchlings. Also, discover how some dinosaurs evolved into birds, thus surviving the ultimate calamity—mass extinction.

This volume of the Encyclopedia of the Human Body discusses the parts of the circulatory system and how they work together to deliver nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen and remove waste materials and carbon dioxide. Blood pressure, blood type, and fetal circulation are covered. The history of research on the circulatory system is presented, and the future of research in this field is considered. Current controversies and dilemmas, such as stem cell research, are explored. Circulatory system diseases and disorders, symptoms, and treatments are explored, including anemia, leukemia, and heart murmurs. This reference concludes with a comprehensive glossary, and resources for further information including Web sites and contact information for organizations and national health institutions.

With each step you take, whether it’s outside your back door, at the edge of a nearby pond, or along a path in a national park, you may be setting down your foot in the same place that a dinosaur once did. Just imagine, dinosaurs roaming the same earth we live on today! What an amazing place our planet must have been during the time of those mighty creatures. There were enormous plant-eating dinosaurs, perhaps gathered in herds, grazing in a forest-surrounded meadow. And there were packs of small but fast and smart meat-eating dinosaurs that searched for an opportunity to attack their prey. And there was the ultimate predator in the Tyrannosaurus rex, causing other dinosaurs to flee wherever he went.The Fact Atlas series welcomes you to the world of dinosaurs, vanished now but for the efforts of scientists, museums, and your own imagination. With a little help from this fact-filled dinosaur book, the prehistoric world comes alive with dinosaurs big and small, scary and just plain fascinating. This book offers a history of dinosaurs that challenges young readers to question and research what these prehistoric creatures were really like and why. Illustrations accompany dino statistics to help kids build the closest possible understanding to what it was like when dinosaurs roamed the earth.
