Continuity mistake: After Dr. Alan Grant gets done talking with Ellie, he backs up in his car. As he pulls away, we can see that the interior dome/map light is blaring down on his hands that are on the steering wheel. After the instant angle change, however, the light is now turned off. It cannot be argued that the light turned off automatically during that split second angle change because when the doors of a car are already closed, and the car is started -- the light turns off instantly (if not already off) So this being the case, the light was manually turned in the first shot, and then it was off in the next. (00:06:35)
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: In the diner, when Mr. Kirby is bribing Dr. Grant, after he says "We'd love to make a contribution to your research here" Dr. Grant lowers his glass to the table. In the following shot he does it again. (00:15:10)
Visible crew/equipment: When the group is flying into the island, there's a shot of the plane flying in front of the cloud, and there's the obvious shadow of the helicopter that filmed that shot. (00:15:25)
Visible crew/equipment: Just after hearing the Spinosaurus roar, bright studio lights are reflected on the front of the plane when it is turning to take off from Isla Sorna. (00:19:45)
Revealing mistake: When the Spinosaurus pulls Nash out of the plane you can see a little section of animatronics equipment behind the Spinosaur that's supposed to be the stand. (00:23:45)
Continuity mistake: When the front of the plane is ripped off, there are 2 people sat in the pilot and co pilot seat. As the camera changes one of them has disappeared from the seat and is further back in the plane. (00:24:50)
Visible crew/equipment: Once inside the abandoned building on the island they proceed to walk down some steps after the candy machines. The upper body of a lurking crew member can be seen in a lit doorway in the background of the shot as the group descend the metal staircase. (00:39:39)
Continuity mistake: When 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. When Dr. Grant asks the kid about Ian Malcolm's book, the wrapper is intact. (00:46:40)
Visible crew/equipment: When Paul Kirby is climbing onto the crane in the river sequence you can see a light to the left of the operator's cabin. There was no power on that side of the island to power the light. To the right you can even see a blue tent standing perfectly. Surely the wind would have blown it over by now. (01:15:30)
Continuity mistake: When Sam Neill opens the bag with the Raptor eggs in it, you can see the part of the bag that separates the eggs is completely intact, but in the next shot, that piece of the bag is all ripped and damaged. (01:19:55)
Audio problem: After the aeroplane crashed, a dinosaur stepped over it and the windows shattered making the typical sound of made-of-glass things when broken. They are made of plexiglass (a sort of fibrous plastic).
Factual error: There is no way a 2001 phone's tiny speaker could be heard a hundred meters away in the belly of a dinosaur or later buried in a mound of dino dung.
Plot hole: The spinosaurus manages to smash through a metal reinforced wall designed to stop dinosaurs getting past it without too much effort, yet it can't get through a wooden gate secured by some metal bars. It makes no sense.
Continuity mistake: When Dr. Grant dives in the water after they're attacked, he has his watch on his right hand before he dives in, but in the rest of the shots of Sam Neill he has his watch on his left hand.
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.
Revealing mistake: When the raptor in the InGen compound calls for help, the shots of the raptors responding are shots taken from other scenes in the movie.
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.
Suggested correction: The Spinosaurus used its full body force to smash the fence. The gate, being a smaller target, was too small for the Spinosaurus to use its full body force.
