Continuity: During the opening sequence a couple shots show it raining where other shots have no rain and a dry environment. First noticed after Muldoon says "Jophery raise the gate" and when the gatekeeper falls off the transport box.

Visible crew/equipment: In the opening scene, a velociraptor is being introduced into the park from a shipping container. The velociraptor runs into the gate as it opens, knocking Jophery off the top; he falls to the ground and is attacked. As he falls, two hands come in to break his fall and prevent him from hitting the camera.

Continuity: In the opening scene, when Jophery falls from the cage, he lands on his front. The shot changes to a wide view and he is now on his back and rolls over to get up.

Continuity: In the opening sequence, just after Jophery has been grabbed by the Velociraptor, he gets dragged up in the air. Muldoon reaches up for him then, in the next shot, he reaches up for him again.

Continuity: During the close-up shots of Jophery being attacked by the velociraptor, he has been lifted high up but in an intermediate wide shot he can be seen back down on the floor.

Continuity: In the opening scene Jophery is being attacked by the dinosaur in the cage and Muldoon is holding onto him while the workers shock the dinosaur. Muldoon's hat is on in one shot, then the camera cuts and it is off while the camera is dollying forward, then it is on again. This happens just as he is about to shout "SHOOT HER! SHOOT HER!"

Revealing: In the opening scene Jophery is being attacked by the velociraptor. As the camera pans along the outside of the cage, in between the flashes one can see his legs inside the cage and that nothing is actually attacking him.

Continuity: At the start of the Badlands sequence, the palaeontologists are brushing-out a dinosaur skeleton. In the close-up shot, they are working on the head (someone 'picks its nose') and one of them has a red-handled brush. When we cut to a wide shot, there is only one person working on the head (the nose is still being brushed) and there is no red-handled brush in sight.

Continuity: In the scene at the badlands when Hammond's chopper has landed and Grant goes to the trailer and opens the door, if you watch the hinges of the door, they're on one side then it cuts to the inside of the trailer and the hinges are on the other side.

Revealing: In the Badlands scene, when Dr. Grant enters the trailer there is a large overhead shade blocking out direct sunlight. On the inside light is streaming through the windows.

Continuity: In the badlands segment of the film, after Ellie, Allan, and Hammond enter the trailer. Hammond decides to open the bottle of champagne that Ellie, and Allen were saving. Hammond begins to buff a couple of glasses with a towel that magically changes to a pink towel in the next shot.

Continuity: Hammond pours champagne into his glass and it's full of foam. After Grant says his line, when Hammond says, "...for the next three years." the foam is all gone. Foam from champagne takes longer to disappear.

Continuity: The satchel of money Nedry receives as a down payment for getting the embryos off the island vanishes from his arms as he looks at the false container of shaving cream. It vanishes mid-sentence; he had no time to put it down.

Continuity: When Nedry is trying out the shaving foam can, he puts some on his right hand. When the camera pans back after he's wiped most of it off on the pie, his hand is suddenly completely clean. He then pretends to wipe it off with a napkin anyway.

Continuity: When they first land on the island, the actors' positions change. In the interior shots, Satler is sitting to Hammond's left during the descent. When the copter door opens, Hammond is on the other side, his left side facing the door. They would not have switched places during the descent.

Continuity: Near the beginning, when the helicopter lands on the island, the Jeeps are already waiting in position. In the next shot they reverse up to the helicopters again.

Continuity: When the helicopter first lands on the island it is clearly not on the cross on the landing pad. Later in the scene it is.

Continuity: When we first meet the dinosaurs Alan is sitting in front of a lake. Ellie is standing right in front of him. After the cut Ellie comes to Alan from behind and puts her hands on his shoulders.

Continuity: In the scene where the baby dinosaur is born, one minute the robotic hand is there behind the egg as it's hatching, then in the reverse angle the hand's suddenly disappeared.

Continuity: When the baby dinosaur is breaking the egg, the eggshell is almost open on one shot, and starting to break with a different shape, in the next shot.
