Yeah, Utahraptor. It would be my favorite for a variety of reasons -- and it is in Valley 1 or 2, I can't remember which -- but... that name. So deinonychus it is, because the name sounds coolest.
A couple of points, though:
1. Dinosaurs are a really minor part of this in general.
2. There are a lot of other cool monsters, aliens, robots, and so on. Most of them not humanoid, but some humanoid.
3. I'm not sure about robot dinos, but maybe.
