Take a fun, fact-filled trip back to Earth as it was 430 million years ago. Then, watch as continents drift and oceans take shape. Watch out (!) as fish get toothier, plants stretch skywards and bugs get bigger. Soon fish get feet and four-legged creatures stalk the planet. Here's the story of Earth in conversational text, informative illustrations, and humorous cartoons. Complete with time line, pronunciation guide, glossary and index. "The use of age-appropriate appendixes...make this an exemplary curriculum support resource, but kids who dig dinosaurs will read the book purely for pleasure. Let's hope this author-illustrator will decide to present more history for young readers." —Starred review, Booklist
