Dinosaurs ruled the Earth millions of years ago - and, well, they still pretty much rule. COSI knows it, and so does your inner Tyrannosaurus rex, which sometimes makes you want to walk around in a roaring, tiny-armed stomp. On Saturday, the science center will open "Dinosaurs: Explore. Escape. Survive.," a new exhibit that brings to life the awesome age of the terrible lizards.

Animatronic dinosaurs will move and make noise as amateur paleontologists wander through 10,000 square feet of interactive exhibits. The museum's latest adventure will also offer chances to dig for fossils and imitate dino behavior.
