The idea of the family-friendly show, organizers say, is to replicate the experience of standing among realistic dinosaurs long before homo sapiens walked the planet. Dozens of true-to-size robo-dinos will roam the Expo Center, tilting their heads, opening their mouths and even appearing to breathe. Jurassic Quest staffers worked with paleontologists to re-create the dinosaurs to ensure the creatures’ body language, gait and appearance were accurate.
