In the year 2015, dinosaurs will walk the Earth again -- in "Jurassic World," out on June 12, and now also by way of Disney-Pixar in "The Good Dinosaur," which released its first teaser this week. The 3D animated adventure directed by Peter Sohn, known for his voice roles in an incredible roster of animated hits including "Ratatouille," imagines an alternative history in which the asteroid that torpedoed into our planet and wiped out the dinosaurs instead just streaks pass without impact.
