A dinosaurs activity coloring book is something that engages children because dinosaurs are innately fascinating to many children. Dinosaurs ruled the earth millions and millions of years ago, and these enormous animals are completely different from the dogs and cats that your child is inherently familiar with. Dinosaurs are big and dramatic, and children will love a chance to get to know these so-called "terrible lizards" in the cozy context of a coloring book. The exotic shapes and figures of the dinosaurs encourage children to be creative with their crayons!
