1974-Korg: 70,000 B.C.

This was a Hanna-Barbera live action show that aired on Saturday mornings in 1974 and 75.
I have not been able to find much information on this series, it is omitted from one of my reference books and there is no Wikipedia entry.
This was a serious attempt to depict the struggle for survival of a Neanderthal family, "based on assumptions and theories drawn from artifacts." The American Museum of Natural History in New York and the Los Angeles County Museum of Natural History both were consultants on this show.
Not sure if this could get produced as kid's TV in today's political climate.
Records differ on the number of episodes aired, IMDB says 16 episodes, my book says 24.
