A feature I would love to see is more of a flowed fight, instead of them circling each other and they take turns biting. I would love to see some more action in it and movement something like JW Indominous fight and T rex. So that its not predictable and makes it better for cinematic movies and whatnot, this could also tie into collisions for trees and buildings when they get destroyed when dino X slams Dino Y into it. And one more suggestion the mosasaur can jump out of the water and grab medium herbivores to large carnivores if they are close enough.
