Eye-catching illustrations and the combination of two perennially popular topics make this book a sure hit. The conversational tone of the text and the use of a variably sized and colored display type add appeal, though they may also lead readers to expect a story for younger listeners rather than a serious examination of the subject. Judge is careful to distinguish between facts and educated guesses, which ironically may create a bit of confusion as her audience considers the plethora of possibilities described in her wide-ranging overview. She notes the enormous difference in size between some dinosaurs and their offspring and speculates about how their babies might have struggled to survive. Comparisons are drawn between the behavior of present-day birds (who may actually have evolved from dinosaurs) and a variety of dinosaurs using evidence from the fossil record. Vivid paintings provide amplification, perspective and humor. Further facts about the eight dinosaurs discussed are included, along with a simplified timeline. The glossary and bibliography will assist readers and listeners in understanding the complex ideas presented. Engaging and challenging. (author’s note) (Nonfiction. 8-12)
