The T. Rex was strong, with teeth sharp as knives. When most dinos saw him, they ran for their lives! And so Dr. Seuss' Cat in the Hat introduces young readers to the fiercest of all the many extinct reptiles featured in this exciting exploration of the Age of Dinosaurs. This title forms part of a series of books that takes an off-beat look at natural history through a fun combination of Seussian rhymes and zany illustrations. Aimed at early readers -- from four to seven year olds -- the books are designed to bridge the gap between concept books written for preschoolers and more formal non fiction titles that require fluent reading skills. By presenting the facts in a lively and rhythmic manner, they provide the critical foundation upon which complex facts and ideas can eventually be built.
