[1] The series, about a contemporary family sucked by a vortex back to the Stone Age was intended to be educational as well as entertaining, demonstrating the early human uses of fire, clothing, weapons and cooking.

The Butlers meet and befriend a clan of Neanderthal cavepeople led by Gorok, his wife Gara, their teenage son Lok, and their young daughter Tana.

Examples of such included introducing Gorok's family to basic technology, such as simple machines (particularly the lever and the wheel), sailboats and windmills.

On March 22, 2011, Warner Archive released Valley of the Dinosaurs: The Complete Series on DVD in region 1 as part of their Hanna-Barbera Classic Collection.
