The site is China, millions of years ago, where dinosaur hatchlings emerge from their eggs, then, in successive illustrations, grow to gigantic size. Death comes years later when they are caught in a flood. Final illustrations show their bones being discovered in our own era and being mounted for display in a museum.
Original pictorial treatments of places and events in history make these books as entertaining as they are informative for young readers. Each title covers a single theme with a series of time-sequence illustrations that show how one location has changed over the course of history. Each illustration covers a large two-page spread. Tabs on page edges provide identifying historical dates for each picture, and have labels to explain details in the illustration. A Glossary at the back of each book defines relevant terms.
