What happened to the dinosaurs? For millions of years these fantastic creatures roamed our planet. Then, suddenly, they all disappeared. Scientists wonder why. What could have caused this huge extinction 65 million years ago? In this enlarged edition, distinguished writer Franklyn M. Branley and award-winning artist Marc Simont provide the perfect introduction to an always fascinating subject - the disappearance of the dinosaurs. Outstanding Science Trade Books for Children 1989 (NSTA/CBC)
From the king of the dinosaurs the Tyrannosaurus Rex to the formidable Brachiosaurus, dinosaurs are a perennial favorite of children of all ages. The 14 stunning images in this bookazine reveal the dinosaurs as you have never seen them before. Every poster is accompanied by the facts and figures surrounding the individual dinosaurs, including information about their habitat, food and predators. Featuring a dinosaur family tree and scale pictures to help compare the size and dominance of these incredible beasts, this entertaining and educational collection will captivate and amaze.
What can long-dead dinosaurs teach us about our future? Plenty, according to paleontologist Kenneth Lacovara, who has discovered some of the largest creatures to ever walk the Earth. By tapping into the ubiquitous wonder that dinosaurs inspire, Lacovara weaves together the stories of our geological awakening, of humanity’s epic struggle to understand the nature of deep time, the meaning of fossils, and our own place on the vast and bountiful tree of life. Go on a journey––back to when dinosaurs ruled the Earth––to discover how dinosaurs achieved feats unparalleled by any other group of animals. Learn the secrets of how paleontologists find fossils, and explore quirky, but profound questions, such as: Is a penguin a dinosaur? And, how are the tiny arms of T. rex the key to its power and ferocity? In this revealing book, Lacovara offers the latest ideas about the shocking and calamitous death of the dinosaurs and ties their vulnerabilities to our own. Why Dinosaurs Matter is compelling and engaging—a great reminder that our place on this planet is both precarious and potentially fleeting. “As we move into an uncertain environmental future, it has never been more important to understand the past.”
'What Happened to the Dinosaurs' investigates why these huge creatures disappeared. The important question, 'How do we know they existed?' is answered with a clear timeline of images. Various theories are suggested, which support knowledge and understanding of climate change, volcanoes, asteroids and evolution of the animals which did survive. *Topaz/ Band 13 books offer longer and more demanding reads for children to investigate and evaluate. * Text type - An information book. * The response page summarises the main theories and could support a presented talk. * Curriculum links - Science: Living things in their environment. * This book has been quizzed for Accelerated Reader
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.
