Fan Casting Wild Child in Cadillacs and Dinosaurs

A wild child who's raised by the Griths that wears a loincloth and animal hide boots. He does not speak any human language, but can communicate with the dinosaurs. His parents were killed by a Shivat when he was only three years old and was then attacked by a pack of cave hyenas, but was saved by the Grith, who then raised him as one of their own. Years later, Hannah discovered Wild Child and tried to take him back, but eventually knew that he belonged with the Grith.
