During the Mesozoic Era or “Age of Dinosaurs” creatures small and large roamed the earth, swam in the seas, and flew across the sky. Even though they have been extinct for about 65 million years, kids and adults alike are fascinated by a life form in which we know very little about. Artist P.D. Moreno brings the action and excitement that naturally comes along with Dinosaurs to your home in this 300 piece jigsaw puzzle. The finished size of this puzzle is 18" x 24" and is great for kids.
