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)
Visible crew/equipment: When Lowery says "that first park was legit" two light screens are reflected in his glasses. (00:11:30)
