Paleontology may conjure images of towering dinosaur bones, but fossilized plants are equally important to unlocking a more complete understanding of the prehistoric world. This entry in the Incredible Changes on Earth series (6 titles) focuses on prehistoric plants, some of which still exist virtually unchanged. After a quick gander at some impressive dinosaurs, readers are introduced to paleontology. But the book goes beyond the usual dinosaur bones: preserved plants, petrified wood, and insects trapped in amber are all mentioned as ways to get a glimpse of ancient biology. Realistic dinosaur depictions, dramatic photos, and inset text boxes grab attention and convey information in an easily digestible form. Clear, explanatory content features pronunciation guides and boldface vocabulary, and helpful back matter includes a quiz, a glossary, an index, and suggested questions. An enjoyable introduction of an often-overlooked part of paleontology.
