Anime: Genshi Shounen Ryuu

The story is set in prehistoric times, where humans coexist with dinosaurs. One day, a baby named Ryuu is born into the world. Since Ryuu has white skin, which is different from the rest of his tribe, the tribe elder accuses his mother of breaking the divine law. Consequently, the tribesmen separate Ryuu from his mother and leave him on a rock as a sacrifice to a terrible Tyrannosaurus named Tyranno. Thankfully, the baby is picked up by an ape named Kitty who raises him as her own child. Meanwhile, Ryuu's real mother leaves the tribe on a quest to find him.

10 years later, Ryuu meets a beautiful girl named Ran who was sold to the tribe he originally came from. The tribe is not happy to see Ryuu alive and tries to sacrifice him again, this time by burning him alive. Before they can get the deed done, the tribe is massacred along with Ryuu's adoptive mother by Tyranno. Ryuu then sets out on a long and difficult journey together with Ran to find his real mother and Ran's younger brother Don, who was separated from her at an early age.
