The explanation would have to be either beached animals or floating carcasses.

Personally I don't see why they should not be included in the series, after all most people would at least recognise a Plesiosaurus and consider it to be a "Dinosaur" even if that's wrong. Just about every dinosaur book or toy line features a Plesiosaur, and I can't understand why Hammond and InGen would not want to showcase one as it would be a guaranteed hit with the public, especially kids. It would be an actual sea monster.

My only hope is that if they do show a Plesiousaurus, they don't show it rearing its head and neck out of the water in that S shape that has since been disproven as being possible.
