And since hybrid dino races are artificial in origin and no one was arounf back then to make an artificial dino, hybrid fossils don't exist. Even if two creatures were smashed together and fossilized together, they would be seperate individuals. They would probably have some kind of relationship with each other probably as sisters but they'd remain seperate entities.
