Wheel of Facts No questions, just information. It's like a manual search engine: you turn the 11-3/8 dia wheel and read the facts in the little windows. The Dinoscope features (40) prehistoric beasties with illustrations, a time line, geological periods, pronunciation, meanings of the names, fossil locations, size, habitat and diet. A fun way to learn.
