DISCOVER DINOSAURS Chris McGowan Illustrated by Tina Holdcroft Toronto, Kids Can Press, 1992. 96pp, paper, $10.95 ISBN 1-55074-048-2. (Royal Ontario Museum Discover series). CIP. Grades 3 to 7/Ages 8 to 12 Reviewed by Pat Steenbergen. Volume 20 Number 6 1992 November How fast could dinosaurs run and how do paleontologists know? Discover Dinosaurs, the third book in the "Discover" series from the ROM, will answer these and other questions about dinosaurs you didn't know enough to ask. Dr. McGowan's writing is clear, logically organized and accessible to the target audience of eight- to twelve-year-olds. The illustrations by Tina Holdcroft amplify the text. Each of the more than thirty topics includes an experiment or activity to illustrate the concept and further children's under­standing. Activities range in complexity from walking as a quadruped to building a model pterosaur. It is these activities, the clear writing and the breadth of topics covered that make this book stand out among the dinosaur books available today. A table of contents, glossary, list of activities and experiments, an index and answers to problems posed in the book are all included. Because of new discoveries and reinterpretations of existing fossils, even the dinosaur books need to be kept up to date. This book is recommended for all school and public libraries. Pat Steenbergen job shares as the librarian in the Professional Library for the staff of the Board of Education for the City of York in Toronto, Ontario.
