In association with the Smithsonian, this classic picture book introduces dinosaurs of all shapes and sizes in bold, rhyming text--includes a pull-out poster featuring all the dinosaurs! Dinosaur weak, dinosaur strong, dinosaur short or very, very long. There are all sorts of dinosaurs, from sweet to grumpy, from spiky to lumpy. Introduce young children to prehistoric pals and the concept of opposites as the dinos race, roar, and stomp their way to their lunch!
