Exactly! Also, on further thought, I think the "Predator vs Dinosaurs" movie does exist, except it's not obvious at first glance. It's this Adam Driver movie called "65", and while the protagonist is obviously played by a human, the timeline (65 million years ago on Earth) and a couple of key scenes opens the interpretation that these are actually an alien species just portrayed by humans to make the narrative more relatable. In that interpretation, it's possible for this alien species to be an ancestor of the Predator species.
