The main goal of the exhibit was to have visitors understand the amazing diversity among Pterosaurs. Exhibit volunteers helped to achieve this goal by building everything from “rock blocks” and puzzles, to actual models of the fliers themselves. Don Puffer created a 4-foot mechanical Dsungaripterous pterosaur also known as “Clam Digger” that demonstrated the opening and closing of its wings. Ed Mack's sculpture Pteranodon sternbergi is a stunning life-size model that should amaze the museum audience and now hangs over Dinosaur Mountain.
