Sky Monsters DVD
In the Mesozoic Era, dinosaurs may have ruled the earth, but the skies belonged to flying reptiles, ranging from sparrow-sized creatures to behemoths with 35-foot wingspans, known as pterosaurs. Explore their aerial realm in this National Geographicprogram that uses computer graphics to show how these predators lived and hunted, and watch engineers create a mechanical pterosaur to learn how they flew. 90 min. Widescreen; Soundtrack: English Dolby Digital stereo; photo gallery.
