Goofs

During the Spinosaurus plane attack Paul Kirby leaves the plane and shouts "Amanda!". His lips clearly aren't moving in the shot so the line was obviously added post-production.

(at around 11 mins) During the Montana dig site scene, Billy is carefully using a toothbrush to gently wipe away dirt from a dinosaur fossil while trying to impress his female co-worker. But at the same time, his arm and all its weight is leaning directly on a big part of the fragile fossil. No fossil expert would ever be so careless.

(at around 51 mins) Eric has survived several weeks in the water truck and knows he might need it again. But he leaves the hatch open, meaning anything might occupy it.

(at around 1h 21 mins) When the Marines are disembarking the amphibious vehicles, one is seen getting off with his finger on the trigger of his rifle. Soldiers are specifically trained to keep their fingers off the trigger of their weapons to avoid accidental discharges, especially during the rapid disembarking of a vehicle.

(at around 56 mins) In one sequence, the Spinosaurus, whilst pursuing the main characters, smashes through a huge metal reinforced fence to get to them. Seconds later the main characters run in a small wooden hut and the Spinosaurus isn't able to break into it. How can it smash a steel fence open yet not be able to even slightly damage a wooden hut?

(at around 1h 22 mins) Trees suddenly appear on a previously treeless beach as the helicopter takes off.

(at around 1h 4 mins) When Kirby goes to the end of the tunnel in the birdcage his backpack is on, then when the camera returns to him the backpack is off.

(at around 21 mins) After landing on the island, as they run back to the plane in a panic you can hear gunshots from behind them of the missing team member coming from the direction in which they all walked. They start the plane, turn in 180 degrees and head down the landing strip at full take off speed, when suddenly about a half mile down the strip the same missing team member walks out into the strip about another half a mile in front of them waving his arms. No way he would have got there that quickly.

(at around 1 min) In the opening scene the man with the camera using the parachute with the kid, his shorts change color from tan to black several times between shots.

(at around 47 mins) The Nestle candy bar when Dr. Grant and Eric are having a conversation in the water truck changes constantly throughout the scene.

(at around 15 mins) While talking to the Kirbys in the bar, Grant puts his drinking glass down twice when Paul offers to fund his dig.

(at around 1h 8 mins) When Dr. Grant is talking to Eric on the boat you can see/tell that the boat is moving when the camera is on Dr. Grant, but it's still when the camera is on Eric.

(at around 2 mins) During the opening scene of the movie while Eric and Ben are para sailing, Ben starts to film with a video camera. While videoing the tugging begins, the next scene the camera is gone, but the next it's back again. After this Ben slides the camera to his side and the camera disappears out of his hand.

(at around 22 mins) Just after the plane crashes in the tree, Kirby unbuckles his seat belt twice.

(at around 4 mins) When Ellie is walking toward Alan with her toddler, her shirt gets pulled a little bit of the way up her belly and then it falls again. When she's by Alan, her belly is covered. But at that moment as the scene changes, Ellie's belly button is showing.

(at around 1h 6 mins) After saving Eric, Billy is left dangling in the parachute harness. When he unlocks the straps, he falls into the water below, completely submerging. A few seconds later, he emerges from the water and begins running with the water barely ankle deep. In the cuts after that, the water is now up to between his knees and waist.

(at around 5 mins) Dr. Degler's coffee cup disappears during her dinner with Dr. Grant.

(at around 3 mins) In the beginning, when the two people are killed on the boat, Eric and Ben see a small rock ahead, that rock disappears between shots.

(at around 2 mins) A crew boat is visible in the background of one shot just before the parasailing boat enters the fog.

(at around 1h 16 mins) Wires visible on Paul while hanging off the crane.

At 39:40 when the group enter the egg incubation room, as they walk down the staircase, you can notice a crew member in a yellow-lit doorway at the far corner of the room.

(at around 21 mins) Lights reflected in the plane when it trying to leave Isla Sorna.

(at around 10 mins) When Dr. Grant's team is excavating in the Montana Badlands, a wood thrush is heard in the background. The wood thrush isn't found in Montana and would certainly not be live in a desert environment.

(at around 1h 2 mins) Although the depiction of the Pteranodon showcases several inaccuracies (such as having teeth, being able to grab things with their legs, and being excessively aggressive), which, being genetically engineered clones, can be explained, one detail still counts as an error. Namely, no matter how strong these creatures are, they could never lift up and carry a human boy the size of Eric. They would simply plummet towards the ground, since these animals needed to be extremely light-weight in order to stay aloft (a real-life Pteranodon would weigh less than preschool child). Thus the Pteranodon's anatomical inaccuracies notwithstanding, the sequence in question very nearly breaks the laws of physics.

(at around 33 mins) The Kirbys' camcorder is a Panasonic Digital "Palmcorder" (a PV-DV910 or similar), as evidenced by the distinctive zoom buttons, tape window, and connector for a light. It is a MiniDV (digital) camcorder, yet when Grant, Udesky, and the Kirbys play the tape that Eric and Ben shot, there are analog tape artifacts, most notably the static that appears during cuts and at the end of the tape. Static wouldn't appear on a MiniDV recording, and neither would analog tape artifacts (unless that is exactly what was recorded, which is highly unlikely with a working camcorder). The cuts would either be seamless (or the screen would turn blue), and at the end of the tape, the screen would turn blue, possibly preceded by a few milliseconds of a still of the last frame recorded. This is a common error in movies when digital camcorder footage is played.

(at around 17 mins) As the aircraft approaches the island, after air traffic control warns the pilot about violating the restricted airspace, Mr. Udesky correctly turns off all the audio switches on the panel for the King Air's radios. However when he leans back in his seat, looking over his left shoulder the airspeed indicator reads ZERO (12 o'clock) position. This wouldn't be the case if the plane were flying.

(at around 1h 23 mins) When leaving the Island they are departing on a SH-60B Helicopter, the interior of which is nowhere near quiet enough for them to hold a conversation, nor laid out for them to be sitting in that configuration, especially with someone is being medically evacuated.

Paleontologists have calculated that the bite force of an adult Tyrannosaurus Rex would have been in excess of six-tons-per-square-inch. With this in mind, it is all but impossible that the Spinosaurus would have even survived the Tyrannosaurus Rex bite to its neck, let alone shaken it off and continued to fight.

While separated Eric hears the satellite phone ringing and claims that it is Mr. Kirby's based on the ring tone. Mr. Kirby confirms later that it is HIS satellite phone, but at the start of the movie Udesky is shown to be the actual owner of the phone. The ringtone is the same "Kirby paint and tile in Westgate" as well and it is actually Kirby contacting Udesky for the first time.

There are numerous instances where dinosaurs are portrayed in a manner inconsistent with widely published dinosaur hypotheses. These can be explained within the movie's world as errors or deliberate alterations by the characters who made the InGen cloning process.

(at around 55 mins) While celebrating Eric's return, Eric explains he followed Mr. Kirby's cell phone jingle. Then they turn around to see a Spinosaurus standing there. It would have been impossible for the Spinosaurus to have gotten there unnoticed since a T-Rex creates impact tremors with every step when it walks and a Spinosaurus is bigger, according to Grant, than a T-Rex. It is also impossible for it to have been there the whole time since no one seemed to notice it standing there.

(at around 56 mins) The "metal" wire ropes at the barrier fence where Alan and Eric reunite with rest of the survivors are obviously sash cords spray-painted gray. This is even more apparent when Alan and Eric run through the hole in the fence and the dangling ends of the broken ropes can be seen flopping around as they accidentally make contact with them.

(at around 59 mins) After escaping from the Spinosaurus and deciding not to drop the raptor eggs, the main characters go down the spiral staircase. Right before the metal stairs they find below break under the weight of Dr. Grant, the camera pans down the stairs and the clean cut where the stairs are about to break can clearly be seen two stairs down. The camera pulls back, and clean cuts can also be seen on the railings of both sides of the staircase just where it breaks.

When the man and boy begin para-sailing in the opening sequence, as they lift off from the boat an overhead shot looks down at them with the boat almost directly below them, but the boat is not moving and has no wake.
