No dinosaurs specifically lived in the water. Plesiosaurs, pliosaurs, mosasaurs and ichthyosaurs lived in the water (but are not DINOSAURS). They are reptiles but not dinosaurs. They co-inhabited the planet with dinosaurs, in the same way that the pterosaurs ruled the air. Pterosaurs were not dinosaurs either.
