Gr1-4 110 million years ago, a lush river flowed through the heart of what is now a desert in Africa. Lurking in the depths of the river, a humungous monster waited for its prey to come to the river's edge to drink and to die. More than 40 feet long, this giant ancestor of the crocodile stalked and killed dinosaurs. In 1997, dinosaur hunter Paul Sereno discovered the enormous reptile fossil named SuperCroc. Learn how modern science uncovers the ancient past in this thrilling account of a prehistoric predator.
Welcome to this highly memorable one-stop guide to the world of dinos. Join the primeval party and meet a world of dinosaurs, along with dinners, habitats and fossil discoveries.

Fueling Our Future: An Introduction to Sustainable Energy
One of the most important issues facing humanity today is the prospect of global climate change, brought about primarily by our prolific energy use and heavy dependence on fossil fuels. Fueling Our Future: An Introduction to Sustainable Energy provides a concise overview of current energy demand and supply patterns. It presents a balanced view of how our reliance on fossil fuels can be changed over time so that we have a much more sustainable energy system in the near future. Written in a non-technical and accessible style, the book will appeal to a wide range of readers without scientific backgrounds.
Providing the world's growing population with its increasing demands for energy is a major challenge for science, business and society alike. Energy can be generated from many sources, but not all sources are suitable for every application. Much of today's technology has been built on solid, liquid and gaseous fuels derived from fossil sources. However, the supply of these is finite and their combustion produces carbon dioxide, one of the gases responsible for global warming.
