Living with Dinosaurs

This fitting companion to these collaborators' The News About Dinosaurs vividly recreates life 75 million years ago on a site near the present state of Montana. With almost novelistic narrative skill and a You Are Ther e immediacy, Lauber explores the habitats and habits of a variety of prehistoric life forms. In three chapters, she focuses on environment and ecosystems in and around the sea, the swamps and lowland areas and the more heavily forested uplands. The detailed text is paired with striking mixed-media illustrations; some have been created by Henderson for this book, others are reproductions of works in the Museum of the Rockies. An afterword, ``How We Know What We Know,'' offers intriguing insights into the origins of fossilized remains and methods of current scientific investigations. Numerous colorful maps and a useful index with pronunciations round out this informative and entertaining work. Ages 6-10. (Apr.)
