All of you are saying that Rexy was probably tranquilised. I don't think she needed to be -- we see in both Jurassic Park and Jurassic World that she follows flares. Just chuck a flare into a cage big enough and slam the doors when she's inside and voila -- instant captured T-REX.

And, as for the Spinosaurus and Isla Sorna -- to me it is implied that Isla Sorna was the reject ground. E.g. the place where wrong Dinosaurs or dinosaurs that were too dangerous went.

After all, the Pteranodons on Sorna attacked humans and there are human remains -- this is NOT a good thing to display around people. And the Spinosaurus, through mutations, seems to be super powerful and incredibly dangerous if it can take out a T-Rex and a plane just by walking into it, which, again, makes it much to dangerous to exhibit. The Brachiosaurs on the island are also a different colour -- maybe they were a failed strand of the DNA that didn't work?
