Gigantoraptor

Gigantoraptor ("Giant Seizer") is currently the biggest oviraptorosaur discovered.

Jurassic Park Franchise
The Gigantoraptor was one of the animals seen in Jim Martin's storyboards for Jurassic World that did not apperead in the final film. It was seen as a hologram in the Innovation Center and as the physical animal in a scrapped attraction together with a crestless hadrosaur (most likely Edmontosaurus).

If the Gigantoraptor had made it to the final cut of the film, would be the first oviraptorosaur in the films.
