Modern-day paleontologists reconstruct the Mongolian journey of Roy Chapman Andrews, the American Museum of Natural History scientist who discovered dinosaur skeletons in the Asian country in the 1920s. Dinosaurs Alive! 3D travels across the globe and across time to recreate both this landmark discovery and the exciting creatures he found. Using computer animation, the film brings dinosaurs to life, and it features digs from Mongolia's Gobi Desert to the rocky terrain of New Mexico.
