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 Explorers 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.
