Several visitors to a zoo exhibit called "Dinosaurs Live!" asked for refunds after discovering that dinosaurs ceased to roam the Earth 65 million years ago.
The exhibit at the Memphis Zoo features 21 Dinamation creatures - computerized, mechanical replicas of dinosaurs that move and roar like the real things may have done."We thought when we opened we would have kids who would be frightened by the dinosaurs," Ball said Tuesday. "But little did I know I would have adults who didn't know dinosaurs were dead."
