* Appropriate for grades 2nd - 8th You’ll travel back in time to meet the pterosaurs and the ancestors of modern-day birds: the feathered dinosaurs. Lucy and her father navigate from continent to continent, looking for clues about the origins of flight. When time runs out they experience first-hand the cataclysmic last day of the dinosaurs. Science content includes topics such as continental drift, proper motion of stars, asteroids and impacts, extinctions and the convergent development of flight among species.
