Join two youngsters and their teacher as they discover clues to Dinosaurs: Puzzles from the Past. Putting dinosaurs in perspective is their first task. They follow a time line back from the Age of Man to the era of dinosaurs. Animation introduces a variety of dinosaurs and their environment. Students see fossilized dinosaur bones uncovered by excavators at Dinosaur Provincial Park in Alberta, Canada. They also visit a paleontologist in his lab and see a comparison of bones from two different dinosaurs. At a museum in Ottawa the two youngsters see a full-scale reconstructed tyrannosaur skeleton and identify it as a meat-eater by its feet and teeth.
