Factual error: The battery of the electronic goggles used by Gray should be dead after 20 years. (01:09:30)
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.
Visible crew/equipment: When Masrani puts his sunglasses on you can make out a camera reflection in the glass. (00:15:10)
Continuity mistake: When Claire gets into the helicopter at the start her microphone is level with her mouth. As it takes off, it's pushed down by her shoulder. (00:13:50)
Continuity mistake: When Masrani is driving the chopper for first time, the wire on his headphones is in front of the mic, then behind it. (00:13:30)
Continuity mistake: When Indominous Rex has the gyrosphere in its mouth and is smashing it, the seats are facing up. When the passengers release their safety belts and fall to the ground, they are facing down. (00:59:20)
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.
Continuity mistake: When running towards the Pteradons, Claire is with a group of ACU units. Camera changes and she's not in shot. In the reverse angle, she does run to the side, but even from the front angle she should have been visible. (01:22:00)
Other mistake: When Claire is running to the quad bike she gets a phone call and answers it. However, 1) the phone doesn't light up or show any indication it's ringing and 2) she doesn't press anything but somehow answers the call. (01:19:00)
Continuity mistake: When the boys enter the old visitors centre, they open both doors and leave them open. When Owen and Claire come out through the doors, one of them is closed. (01:08:00 - 01:14:45)
Continuity mistake: When the ACU finds the I-Rex tracker, the way it's held between the first shot of it and the live feed is different. (00:45:45)
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 big flying bird comes down, its beak is pointing at one of the brothers in one shot and at the other in a different shot. (01:22:40)
