Jurassic Park: Builder answered your question pretty good. In order for you to create aquatic creatures in the game, you must collect aquatic parasites fossilized in ice or a similar incasing then extract the blood from them like you would the mosquitos in amber. Though, like extracting blood from insects in amber, it's near impossible in real life.

Another explanation comes from the Trivia section of the Tylosaurus article:

...However, mosquitoes only populate stagnant humid areas rather than coasts. It's more likely that a reptile swam into fresh water in the manner of a bull shark and found itself in a swamp. That is absolutely true. Mosasaurids weren't just salt water creatures, but freshwater too, take a look a some sharks and lizards today, a Crocodile (excluding the Saltwater) can live in both fresh or saltwater regardless, but choose not live in Saltwater because of the salinity and lack of land and food, but they still trend saltwater every now and then and same goes with the Mosasaurs. If they find a bank leading into the mainland or a small stream and river their gonna take it anyways if it means they'll find food or get where they are going to. And a bonus is that Laramidia and Appalachia were countered with the ocean so this was pathway for Mosasaurs back then as well.
