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.

'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
