Gr 3-7–All of the seven megabugs explored here are arthropods. The author defines arthropod, then places these prehistoric creatures in Earth’s time line, providing important information such as the age of the Earth, the names of the geological eras, and the many periods that comprise an era. Information about how fossils are formed and how rocks can be dated is included. Each megabug has a two-page spread and features a colorful, detailed illustration of the creature and its environs (illustrations were reviewed for accuracy by a trio of paleontologists). Facts such as physical characteristics, when it existed, along with its habitat, diet, how it protected itself, and what potentially caused it to go extinct are mentioned.
VERDICT Information is presented clearly and simply in this fascinating (and slightly creepy) exploration of mind-boggling prehistoric megabugs. Recommended for science lovers and casual browsers.
