Valley Of The Dinosaurs (1974)

Main voice cast

Science professor John Butler and his family are on a rafting trip along the Amazon River in an uncharted river canyon when their raft hits a rock and capsizes. They are swept through a cavern and caught in a whirlpool.

Upon resurfacing, they find themselves in a mysterious realm where humans coexist with various prehistoric creatures, including dinosaurs. 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. Gorok and his family have a pet of their own in the form of a baby Stegosaurus named Glump. Gorok's family saved the Butlers' upon their first arrival.

Gorok's family aid the Butlers' efforts to find a means of returning home. For their own part, John and his family do what they can to make the Neanderthals' daily lives easier. Examples of such included introducing Gorok's family to basic technology, such as simple machines (particularly the lever and the wheel), sailboats and windmills.

IMDb lists Margaret Richey (in "Fire") and Andrew Parks as being in the cast but does not name their characters.
