we can't say, because were discovering more all the time. there is actually no such thing as a dinosaur that spent its whole life in water as one of the definitions of a dinosaur is an animal with steady legs that support it on land. any water animal would have flippers so they cant stand. the animals that lived in the water were just animals that lived in the dinosaur period not actual dinosaurs.
