How I think T-Rex will be featured in JW

Hello everyone! I know a lot of is have wondered if T-Rex will be showcased in the film. Colin confirmed it, however it wasn't in the trailer (or was it?) so no one knows how it will be featured yet. Back to the or was it part: a few days ago I posted something about viewing one of those trailers that were leaked, but haven't been released to the public yet. For those who have seen it you'll remember hearing the Rexes roar as a large theropod dinosaur slams into the Gyrosphere. Many think that it was D-Rex as that's what it looks like in the JW trailer. In my opinion I think we where wrong. I think that in some part of the movie either when the park goes to shit or before that Ty and Nicks characters will take the Gyrosphere out for a "joy ride". Now the scene was at night, so it could mean they got lost or the park already went to shit and they didn't know it yet (which explains why Nick Robinson was on his phone when it happened. So that could be one way the Rex was featured. Basically the scene showed Ty panicking and Nick not caring. Nick looks up from his phone and sees the Rex ram into the Gyrosphere. On another note we have seen a short clip of the film with a goat. My explanation: T-Rex Kingdom. Another possible way we could see the Rex is after the kids arrive they see T-Rex kingdom. They walk in, but the Rex is no where to be found so they settle for the Mosasaur feeding show instead.

Also not my theory, but @SilverFalcon had a really great one about the Rex getting D-Rex into the Mosasaur aquarium and have the Mosasaur kill D-Rex!

 So these are a few theories of mine how Rexy will be featured. What do you think? Sorry if already posted! :)
