What cartoon inspired by prehistoric times was produced by Hanna-Barbera?

Founded by animators William Hanna and Joseph Barbera, the studio created hundreds of characters that embedded themselves in audiences of all ages. ‘The Flintstones’ (1960-66). They’re the modern stone-age family living in the prehistoric town of Bedrock, populated by cavemen, dinosaurs, wooly mammoths, and saber-toothed tigers. As it began, it was explicitly set around two couples – Fred & Wilma Flintstone, with their pet dinosaur Dino, and Barney & Betty Rubble.
