I kind of love the idea of them making a new hybrid dinosaur.
Because I saw a description saying "I bet they added this because the studio said you need to have a supermonster to sell this movie because nobody is excited by regular dinosaurs anymore"
and
if that's literally part of the story? The park saying, tourists are getting blase about dinosaurs, we need to attract them? That would be some great commentary on our current relationship with movie magic.
