 The scene, which already included the juxtaposition of live dinosaurs in a museum filled with fossils, while also destroying the bones, now had an ending where the "T. rex" saved the protagonists, and afterwards made what Spielberg described as a "King Kong roar" while an ironic banner reading "When Dinosaurs Ruled the Earth" flew.The film wrapped twelve days ahead of schedule on November 30, and within days, editor Michael Kahn had a rough cut ready, allowing Spielberg to go ahead with filming "Schindler's List".Despite the title of the film's referencing the Jurassic period, "Brachiosaurus" and "Dilophosaurus" are the only dinosaurs featured that actually lived during that time; the other species featured did not exist until the Cretaceous period.
