Dinosaurs once walked our planet long ago during the Jurassic era. Here we see them hunting, playing, and eating once again. An Allosaurus hunts his prey as they come to the water to drink. Archaeopteryx, Rhamphorhynchus, and Pterodactylus all fly high in the air above. Can you find the blue Ornitholestes sneaking away? A Barosaurus and Stegosaurus eat peacefully among the ferns and conifers beyond. A Plesiosaurus watches the others as its head pokes up from the water. What color are the shells of the Ammonites in the water?
