Pretty much all the elements of the first two sequels are ignored in Jurassic World, including the new dinosaurs they introduced. Well, sort of. It may not appear properly, but a skeleton of the Spinosaurus, the main antagonist in Jurassic Park III, can bee seen next to the Winston's Steak House. This minor appearance is turned into something of a f**k you in the third act, when the T-Rex smashes through the skeleton; symbolically making up for the pair's showdown in the third movie.
