Collection: Valley of the Dinosaurs 1975 Series

Based on the animated CBS Saturday morning TV series that aired in 1974. Science teacher John Butler, his wife, his children, and their dog, are on a rafting trip on the Amazon. Their boat capsizes and they're caught in a whirlpool. When they surface, they find themselves in a prehistoric valley where they meet caveman Gorok, his wife Gara, their two children Lok and Tana, and their pet, a baby Stegosaurus named Glump. Gorok and his family help the Butlers in their attempt to find a way to return home, while the Butlers help them by introducing them to basic technology, such as simple machines (the lever and the wheel), sailboats and windmills.
