Continuity mistake: In the scene where Dr. Grant gets rescued by the kid and they are sitting in the water tank (truck) eating candy bars they show the kid eating a "Crunch" bar with no wrapper, just in the tin foil. In the next shot you see him eating the same candy bar but the "Crunch" wrapper is now on, then in the third shot it cuts back to the kid and the wrapper is gone and you only see tin foil again. (00:46:40)
Continuity mistake: If you look at the scene where Grant and company are on the boat during the day, and pass by the field of dinosaurs you will notice that when Eric says "Dr. Grant" they both stand up to look at the dinosaurs, but when the camera shows the boat going along the bank and the dinosaurs, Eric and Grant are sitting and then they stand up.
Continuity mistake: In the fight scene between the Spinosaurus and the Tyrannosaurus, the Tyrannosaurus bites into the Spinosaur's neck, leaving it red in blood. Yet when the two dinosaurs are thrashing at each other, the blood and wounds are gone. Then when the Spinosaurus breaks the Tyrannosaurus' neck, the blood and wounds are back again.
Continuity mistake: During the parasailing scenes at the start of the film we see the boat sailing through the fog and then the ropes being pulled to simulate the attack on the boat. As the boat comes out of the fog we see that its canopy roof has collapsed. The camera switches back to the parasailers and then back to the boat at a lower angle and the canopy is back up, albeit a bit battered.
Continuity mistake: When the group watches the video on Amanda's camcorder it shows footage at the beach and then it shows Ben and Eric para sailing. In this part the words said over the camcorder are noticeably different from the first scene in the movie where the footage was supposedly filmed. This is even more noticeable if you view it with the subtitles on.
Continuity mistake: When Nash is crawling across the ground after the Spino dropped him, you can obviously hear the Spino taking several steps to get him. Yet, after Nash is eaten, the Spino is right in front of the plane when he roars at the rest of the people, as if he ate Nash as soon as he dropped him.
Continuity mistake: When the Spinosaurus bites the cockpit of the plane it hits the floor and breaks. But later when they go back to the plane it is now in perfect condition, and it is when they roll over inside the plane.
Continuity mistake: In the scene where Dr. Grant and the others walk in on the feeding T-Rex, his mouth is slathered in blood. But when the T-Rex is battling the Spinosaurus, its mouth is clean.
Continuity mistake: At the end of the movie when Dr. Grant uses his cell phone to call Ellie and talks to her son it is night where he calls from and morning (judging the Barney reference on TV and that she is kissing her husband off to work) Costa Rica is on the same longitude as Florida and Michigan on the globe. Even if she were living in Maine (which she probably was not) the time from sun up in each location is less than an hour.
Continuity mistake: Near the beginning as Alan is giving his speech, the MC woman is standing, then sitting, then she is standing again but then sits down. (00:08:05)
Continuity mistake: At the start of the film we see two people parasailing. In the close up shots we see that the young boy is lower than the adult, and that the adult is holding the chute's handles above his head. In all of the wide shots, specifically the ones from the side, we see that the boy and adult are level at head hight (boy is harnessed up higher) and that the adult now has the handles at his shoulders.
Continuity mistake: In the scene where the black guy borrowed the cellphone from Mr. Kirby, he had a shotgun on his back, but when he fell to the ground, he had a rifle.
Continuity mistake: In the scene where all of the characters are flying over the dinosaur island, you can clearly see power lines and poles on one of the hills. The island ran all facilities off generators, and would not have this type of power transmission.
Continuity mistake: As the group runs into the aviary, they slam the metal doors shut, bolting them. The spinosaurus repeatedly bashes the doors from the other side. However, you can see through the small gap along the top of the doors that there is nothing that big behind them, not even a shadow is moving; there is only open space and daylight.
Continuity mistake: Tea Leoni's bruise on her cheek changes throughout the movie, once looking like a scratch, once looking like a bruise, etc.
