Detailed, colorful watercolor illustrations enhance this story of a dinosaur-loving family.  Son Carl wants to be a dinosaur and the entire family gets involved with choosing a dinosaur with particular qualities or characteristics.  Twelve dinosaurs that walk, fly, or swim are emphasized as each family member tries to make a decision.  The artwork is large, ample, and vibrant.  The last pages provide additional facts about each dinosaur in the story.  An interesting feature is a timeline of periods from the Permian to the Cretaceous so one can see in which period each dinosaur live.  This is a great mix of fact and fiction.
