Continuity mistake: The restricted zone where the original Jurassic Park was is to the north. After Indominus chases the kids to the waterfall, it is said in the control room that the huge dino is moving south to the crowds waiting for rides to reopen in the downtown section, drawn by the heat signatures of the gathered masses. A few scenes later, Indominus is up north again terrorizing the kids at the Jurassic Park jeep port.
Continuity mistake: When Zack's brother is crying about thinking their parents are going to get divorced, behind Zack it looks like the background loops in every shot of him.
Continuity mistake: When Barry helps Owen get up off the ground, when the camera changes, the shadow of cage bars appear out of nowhere on Barry's back.
Plot hole: What broke the gate the boys went through while driving around in the gyro-sphere? As far as map tracking of the I-Rex it couldn't have been her. So what dangerous dinosaur was hanging out in the west plains?
Suggested correction: It was the Indominous Rex. A major plot element is the fact the Indominous Rex can camouflage itself and hide its heat signature making it impossible for humans to track. The heroes then attempt to track the creature using the velociraptors.
Continuity mistake: When the movie begins, a group of kids are watching a documentary. The employee holding the iPad lowers his right arm, then it's raised again in the following shot.
