The 39-year-old filmmaker revealed that the follow-up will 'take it to the next level' in an interview for the Jurassic Cast Podcast, reported Digital Spy.
Speaking about the sequel, Trevorrow said it will "get to be a different kind of film".
"I feel like the audience has given us permission, to a certain extent, to take this to the next level. I don't necessarily mean in scale. I feel very strongly that it's not about more dinosaurs or bigger and better dinosaurs.
The as-yet untitled "Jurassic World" sequel has a Friday, June 22, 2018 release date in the US, but will be on in UK cinemas from Thursday, June 7, 2018.
Chris Pratt has already signalled his intention to return in "Jurassic World 2", joking that he's already signed for "38 movies or something".
