Ice Age 3: Dawn of the Dinosaurs, the 3rd installment of the Ice Age trilogy, is slated for a July 1, 2009 release. The teaser trailer of the movie was released with the film Horton Hears A Who! that featured the saber-toothed squirrel, Scrat. The trailer suggests that the dinosaurs have been alive the entire time and were in fact living beneath thick layers of ice in a tropical habitat, and that after the ice thaws they will be exposed.
