When Dinosaurs Ruled the Earth (1970)

Set in the ancient (movie) past when people and dinosaurs live side-by-side, a small, struggling tribe sacrifice a blonde to their sun-god in return for protection from the giant creatures that prey upon them. Sanna, one of the sacrificial offerings, escapes when a freak storm interrupts the ceremony. As she searches for a safe haven, she encounters hostility from both rival tribes and many huge, and deadly, beasts.
