User blog comment:Matt Hadick/Jurassic Park 4 Plot Revealed? (SPOILERS)/@comment-2221163-20130622004023

I believe that Trevorrow and Derek Conolly are writing the film's final script. Besides, I think that Spielberg disliked the script written by Rick Jaffa and Amanda Silver, although I am not saying this is that script.

But if this is official, I really don't like the idea of "tamed dinosaurs." It's not like Jurassic Park to do that. And it's not like Jurassic Park for people to have dinosaurs going up against a single, larger dinosaur. The t-rex vs. spinosaurus fight may have seemed unlikely to many people, but it wasn't forced by people. Lastly, this seems like two plots combined - Isla Nublar Lagoon and the new, large and intelligent dinosaur? They don't really go together. And I remember MismeretMonk having a chat about a year ago that even if marine animals were in the film (plesiosaurs, mosasaurs, liopleurodon, etc.), then how would they get the DNA from them? One explanation would be that if any of these animals died and were beached, then maybe mosquitoes made their move there. But all in all, I'm not all that sure about this script.
