This series guides readers through the distinction between dinosaurs and non- dinosaurs. The Pleistocene, Triassic, Juras- sic, and Cretaceous periods are featured in various titles. Each book discusses the time of the dinosaurs and the specific time span of the title, then spotlights four animals such as the Mosasaurus or Dimorphodon. “A Quick Look” shares three facts about the creatures, such as what they ate or what their names mean. Some images are illustrations; others are photographs of paleontologists, fossils, or descendants of ancient creatures. Informa- tion is broken into bite-size chunks, making it easy for readers to digest. A cartoon-style narrator offers comments, such as “T. rex probably ate Triceratops.” Vocabulary terms in bold are defined in the glossary, while pronunciation help is given parenthetically within the text. VERDICT This series will round out collections on prehistoric animals and offer new topics for dinosaur lovers.
