Factual error: When Roland is walking in the pouring rain and talking about killing the T-Rex, he has his gun slung over his shoulder vertically and barrel-upwards. If you were to do this in real-life in a tropical rainstorm for very long, you would run the risk of water entering the barrel and causing problems with the gun. And as a professional hunter Roland would know better.

Continuity: At the San-Diego docks, the guy says it's the 'wee small hours of the morning', yet when he goes inside the Harbour Master's control room, the clock on the wall says 9:25.

Continuity: In the scene when the second INGEN team is rolling through the open field and you first see Rolland talking to Peter about not setting up camp on the game trail, if you look carefully in the shot looking at Peter they are actually on a paved road instead of open field. Split second mistake.

Revealing: When the T-rex escapes into San Diego, it enters a rural area and enters someone's backyard to drink from their pool. When the Rex plunges its face into the water, the water barely ripples and its bottom jaw is as clear as day below the surface of the water. If a beast of that size were to dip its head in the water, no matter how gently, it would've created a ripple that would distort the surface of the water quite significantly.

Revealing: In the beginning of the movie, when the rescue group arrived on Isla Sorna, the actress grabs the Nikon F5 of the photographer and makes her way to the nest of the Stegosaurus. After several shots of the small Stegosaurus there is no more film left in the cassette, so the camera begins to rewind it automatically. The thing is, you never see the rewind knob moving although you hear the camera's motor rewinding (The Nikon F5 has a manual rewind knob to be able to rewind the film when the batteries are dead). There was obviously no film at all in the camera.

Visible crew/equipment: When the two T-rex's surround Eddie's car one bites the roof off if you look to the right side of the roof once in the T-rex's mouth you will see a large wire obviously so the model and the roof don't fall over.

Continuity: When the T-Rexes are far away their steps make the ground shudder so it can be seen in the water puddles. However when they are nearby the same does not occur.

Continuity: In Hammond's bedroom, Ian distinctly asks, "And who are these four lunatics that you're trying to con into this?", before Hammond states the specific number in the team. This is backed up by the subtitles.

Factual error: After Ian and his girlfriend get the baby T-rex from holding in San Diego, they track down the big T-rex. They pull into a gas station and the Trex knocks the large 76 ball towards them. The problem with this is that that gas station/intersection is not in San Diego, CA but in Granada Hills, CA. The cross streets are Rinaldi and Balboa.

Factual error: When the trailer type thing is hanging over a muddy cliff, about to fall off, a guy drives up in a sporty little jeep, ties the trailer to it, and manages to pull the trailer back to safety. Well, at first glance this may seem okay, but that trailer was at least twice the weight of the jeep. And, if the jeep spun its wheels on the mud like that, it would lose any traction it had on the ground, thus going over the edge of the cliff with the trailer.

Continuity: When Rowland and the other man spot the baby T-rex, it is eating its meal. Then it looks up at them. Then it cuts to another shot where Rowland and the other man are talking. If you look in the background you can see the baby with his head down eating again. Then it cuts back to where the baby is. It is looking up at them again.

Continuity: When Ian starts to walk out of Dr. Hammond's office, we see an empty hallway. A shot or two later, there is a butler standing to the left of a lamp in the middle of the hallway. Then another shot or two later, the butler is standing to the left of the hallway where we can't see him.

Continuity: In the scene where Sarah, Malcom and his daughter argue in the trailer for the first time you can see out of the back window. It shows they are right in front of a thicket of trees a few feet behind the trailer. When they step outside a minute later to see the InGen choppers arrive you see that the trailer is pulled up on the cliff tops already. The only view you should have seen out of that window was open sky as the window points out to sea.

Continuity: When Jeff Goldblum is trapped in the car with the raptor outside, the raptor bumps into the window, cracking it. There's no hole in the centre of the crack in the shot of the raptor, but when we see a shot of Jeff Goldblum a second later, there's suddenly a hole in the window.

Factual error: When Hammond is talking with Malcom about going to Sight B he says that the departure is from San Diego which is "a couple of hours" away from there. A flight from San Diego to Costa Rica would take over 5 1/2 hours. Then there is the trip to the island.

Continuity: In the scene when Jeff Goldblum is giving his daughter the news about him going away for a few days, he gives her a piece of paper with someone's number on it.  However in the next scene Jeff has the paper back in his hand.

Continuity: When Sarah gets those cuts on her head, they seem to dissappear or get smaller in number as the movie progresses.

Continuity: At the very beginning, when you see the English family on the beach, the little girl wanders off and you then see a shot of her on her own. However, she must have walked a pretty long way because the beach she is on is definitely not the beach that her parents were on; the rocks in the ocean are gone and the waves are smaller.

Deliberate "mistake": The cargo ship when shown at the dock is a model. When the cargo doors are open they swing out to the sides so T-rex can climb out on to the deck. When they show a real ship heading back to the island, you can see how the doors would open front to back so a dock mounted crane could un-load cargo from the side.

Continuity: Towards the beginning where the girl goes to photograph the Stegosaurus, the scene cuts back to her boyfriend and the guy with the video camera.  In two cuts to their scene while the girl is photographing and interacting with Stegosaurus, the guy with the video camera opens the flip out LCD on the video camera and starts shooting the action.
