The Cat in the Hat makes another surprise appearance at Dick and Sally's house--only this time he makes his entrance riding atop a brachiosaurus! Soon, he's off, along with Dick and Sally, millions of years back in time to see how fossils were created. Then it's on to a tour through the Cat's own Super Dino Museum--a fabulous place where the correct pronunciation of a dinosaur's name wins you a peek at the real living thing! Beginning readers will love exploring the prehistoric world of dinosaurs with the Cat in the Hat as their guide!

Bonnie Worth is the author of countless books for young readers, among them 18 of the Cat in the Hat's Learning Library books, including Oh Say Can You Say Di-No-Saur?, If I Ran the Rain Forest, Oh Say Can You Seed? (winner of the 2003 Ohio Farm Bureau Award), Hark! A Shark!, and If I Ran the Horse Show.
