 Spielberg had three ideas he wanted Jaffa and Silver to incorporate into the script; a fully functioning dinosaur theme park, a human who has a relationship with trained raptors (from Sayles's earlier draft), and a human-eating dinosaur that escapes and has to be stopped.Spielberg also wanted the story to involve children.Jaffa and Silver's draft, titled "Jurassic Park IV", included an early scene set in China, where the fossilized remains of a new dinosaur species are discovered by a Chinese paleontologist.
