Indiana Jones stories have always been anthropocentric. The faith of man. The greed of man. Gods/Aliens helping man. Man protecting X or X protecting man. Mankind at war, etc. Archaeology is the study of mankind through history. Dinosaurs are just dinosaurs they have no direct correlation or impact to mankind; definitely not in a societal way. If Indy was a paleontologist it would fit. He's not. No amount of supernatural shenanigans can make "Indy vs Dinosaurs" work without some suspension of disbelief, IMO. And for this ride in particular any effort to bring Indy into the fold will still feel shoehorned. IMO.
