In the late Cretaceous period, many animals began to take wing, and dinosaurs were no exception. Fly high with our dino-'soar' friends as well as Rain, Emily, and the rest of Dr. Da Vinci's Dinosaur Ex-plorers crew as they find out just how these flying creatures stay afloat! But these time travelers have to be careful--these aren't friendly skies they're flying in; the lord of the skies is an expert predator with a prehistoric eagle eye. It will take luck and ingenuity to survive this era and make it one step closer to making it home.
