I was never a fan of the paleo-marine animals. The park was not ment to be based on those animals, mainly dinosaurs exclusively. In the novel, Wu explains they only used two methods for creating the animals; Mosquitos in Amber and grinding up fossils to use as backups. There was never any marine reptiles in the novels, and I think it would create too much confusion for fans to follow their creation process. That's just me personally...
