Dinoman (middle), also known as amateur paleontoligist Bob Lisaius, raises a tyrannosaurus rex as students from Crab Orchard Elementary School marvel at it and other huge dinosaurs during a performance in the school's gymnasium Wednesday afternoon. Ever the educational entertainer, Lisaius and his wife Dayna have been producing Dinoman Science Series shows for the last 30 years all over the country, teaching kids about everything from the evolution and origins of animals and dinosaurs to how fossils are created over time.
