Revealing mistake: While in the helicopter, Alan's eyes do not align with the location of the Dreadnoughtus. Alan is looking to his far right before the helicopter even approaches the dinosaur and it is shown across the front of the screen. Alan's eyes then stay fixed straight ahead (even after passing the dinosaur), giving the impression he's looking at the dinosaur, but he would have needed to keep turning his neck to the right as the helicopter flew past in order to keep it in sight.

Other mistake: Maisie rides her bike down the snow-covered hill, but when she stops in front of the cabin there is no snow in or on the tire treads and the tires look dry. (00:12:23)

Revealing mistake: After Owen gets a lasso around the neck of the Parasaurolophus and is pulling on the rope, the noose loosens when it should remain taut. Also, the knot was in the center-front of the dino's neck and should have stayed there, but it somehow moved a couple inches clockwise. As Owen continued holding the rope tightly, the knot should have moved back to center-front or be too tight for the dinosaur to breathe. Next, based on the angle of the rope, the knot would be near the top of the neck. (00:08:41 - 00:09:30)

KeyZOid

Deliberate mistake: The decaying tree trunk would have more than likely broken into pieces and/or uprooted from the force exerted by the rope tethered to the pulling Parasaurolophus when Owen wrapped the rope around the trunk to stop the heavy-weight dino, but the trunk held up without even losing a shred of bark. (00:08:36)

Continuity mistake: Blue's baby was standing along her left side when Owen told Maisie to breathe. After a quick camera shift, the baby dinosaur was further back, standing on a log that was more perpendicular to Blue. There had not been any sound suggesting that the baby dinosaur had moved, but there were footstep sounds after the baby jumped off the log. (00:27:47)

KeyZOid

Continuity mistake: Maisie set the front tire of her bike against the side railing of the steps to the cabin. It looked like it might have been sliding down when the camera shifted. Even if the bike did slide onto its side, it was at a different angle on the ground and too far away from where it had been propped. A little later when Owen and Claire where about to go up the stairs, the bike's rear tire was along the front of the steps, not side. (00:12:28 - 00:14:32)

Continuity mistake: During the Jeep's roll-over down the hill, at least the front passenger tire was bent outward/damaged. (It looked like two tires flew off, but all four tires were still on when the Jeep landed on its roof.) The positions of the four tires varied a few times afterwards, from being straight to turned to the left to turned to the right and the tire that was bent outward appeared to be intact (not damaged). (01:44:52 - 01:47:32)

KeyZOid

Revealing mistake: Before the Jeep roll-over, the four people inside were looking upward through some type of 2"x2" fencing (?) as the roof to see the bugs on fire in the sky. The Jeep had a luggage rack and luggage on top, so the "fence" as part of the roof did not make any sense (other than for filming purposes). (01:43:55)

Continuity mistake: Alan had a large brown shoulder bag before he went into the building to listen to Ian's speech, but (like Ellie) did not have his shoulder bag when he got into the lecture hall or after exiting the building. (00:37:20 - 00:40:13)

KeyZOid

Continuity mistake: Before Ellie went into the building to hear Ian's presentation, she was wearing a royal blue sleeveless coat over a brown long-sleeved blouse and had a large brown shoulder bag/purse. When Ellie entered the auditorium, as well as when she went outside after the presentation, she was not wearing the blue coat plus she now had a wallet-sized hand purse but no large shoulder purse. Even IF there was a coat check-in, Ellie would not have left her shoulder purse/bag behind. (00:37:06 - 00:40:13)

KeyZOid

Continuity mistake: When Owen and Claire were sitting at the outside table talking to Franklin, the amount of water in their glasses changed a few times (but neither drank any). Side-rear views of Owen's glass tended to show it about half full, but front views varied from quite low to about two-thirds full. Front views also showed discrepancies in the amounts of water in Owen's and Claire's glasses, such as both about half-full but later Owen's glass two-thirds full and Claire's less than half full.
