3. Utahraptor

While there has been criticism of how Jurassic Park's Velociraptors don't reflect the birdlike nature of the animals as we now understand them, it's worth remembering that, back in 1993, it was one of the first sources really to popularise the notion that dinosaurs were just prehistoric birds. Big and featherless though they may have been, the movie Velociraptors were repeatedly used to suggest that they were birds at heart. At the time of the film's production and release much bigger raptors were being uncovered and researched. Spielberg's funding of paleontological research even resulted in calls suggesting the new species go by the name Utahraptor spielbergi. Probably no tribute to the new generation of dino discoveries in the last two decades could be better than giving Jurassic World bigger, meaner, more birdlike raptors like these. Utahraptors were about 23 feet long, three or four times the size of Velociraptor, with those famous curved tearing claws on their second toes over 9 inches long. Anybody who doesn't want to see a raptor the size of a grizzly bear probably isn't part of Jurassic World's main target audience.
