From Booklist
In this volume in the Let's-Read-and-Find-Out Science series, Zoehfeld builds on children's fascination with dinosaurs by providing technical details about fossil tracks, including information about how they were formed and how some remained, buried underground for millions of years until the soil wore away to reveal them. The clear text is illustrated with informal, colorful spreads of kids at play on the beach where millions of years earlier dinosaurs may have "splooshed through gloppy mud . . . [leaving] footprints behind them." It may be hard for kids to imagine a time span of more than 65 million years, but Zoehfeld brings perspective ("millions of years before any people or any moose or any elephants ever lived"), and, with adult help, elementary-school readers will be able to handle the fascinating facts about the size of the tracks and what the tracks reveal about the dinosaurs that made them.
