Oro is the main character of Abenteuer im Land der Dinosaurier.
Oro is a dark green theropod dinosaur with a lighter tan underbelly. He has a small spine from the top of his head extending all the way down to the end of the tail.
Oro is supposed to an old wise teaching figure in the movie. While he was capable of creating a phonograph-like device that could detect rumbling within the Earth, he is commonly seen to be very poor at his job as he allows his students to fight and claims that "his science will make them fly".
