Patzer

(at around 1h 35 mins) During the Raptor scene, when Sarah and Kelly are hiding from the two Raptors they start to dig a hole by the door. A little while later when the Raptors move to the back of the building, Malcolm runs into the building via the front door but the hole isn't there.

(at around 1h 2 mins) When the trailer is hanging over the cliff, we see the three characters attempting to climb up the rope (after Sarah is narrowly saved from falling through the breaking rear window), but the rope slips loose and they all have to save themselves by grabbing the now-empty rear window frame. However, shortly after, while Eddie is rigging the rope again and also trying to stop the trailers from slipping, a brief shot down through the hanging trailer shows the three of them climbing the rope again.

When the team first sees the dinosaurs, the photographer takes the digital camera out twice and sets it up.

(at around 1h 50 mins) Near the end of the film where Dr. Ian Malcolm and Dr. Sarah Harding crash through the Ingen security gate, there is no rear view mirror attached to the windscreen, yet, when they pull up to get the baby T-Rex, there clearly is one.

(at around 58 mins) When the truck hangs off the cliff, Ian and Sarah are dangling in front of a closet door, with Sarah holding on to the closet's handle, and Ian hanging directly next to her. Yet, in the next shot where the closet door opens, Ian is nowhere to be seen.

(at around 1h 40 mins) San Diego's harbor is one of the trickiest in the world to enter as it has a narrow opening and barrier island blocking it from the open ocean. It also has several channels and the Coronado Bridge limiting access to the harbor.

There's no way that an unmanned ship could traverse this harbor and successfully (or even unsuccessfully) dock itself. The crew would have to be alive, alert and aware or the vessel would have run aground or collided with another ship.

(at around 49 mins) When Dr. Sarah Harding is examining the fracture on the leg of the baby T-Rex, she says the fracture is on the epiphysis. However, the epiphysis is on the ends of a long bone like the tibia she was examining and she wraps the cast around the shaft of the bone, which is the diaphysis.

(at around 1h 23 mins) When Roland attempts to shoot the T-Rex with his .600 Nitro Express, the only noise it makes is a dry fire. Although Nick Van Owen removed the bullet and gunpowder from the cartridge, the primer would still make a loud report when fired.

(at around 58 mins) When the trailer goes over the cliff and Sarah lands on its rear window, the glass starts cracking in a way that ordinary windows would. Vehicle windows are made out of laminated glass, precisely to avoid that effect. A vehicle window would break in such a way that it would fall out in its entirety instead - probably right on impact.

Tembo sees blood on the foliage from Sarah's jacket. Her jacket would have had to been sopping wet with blood, not just still damp "from the humidity" to transfer that much blood to another object.

(at around 1h 45 mins) The T-Rex could not have killed the crew on the ship, before arriving at the San Diego harbor, as he was still confined when the ship reached its destination. Moreover, even if the T-Rex had managed to escape his cage before somehow been confined again, he could not have fit in the ship's bridge -which still seemed structurally intact- and dismember the crew, who were found there< However there was a scene that was cut that explained that velociraptors got on board the ship before it set sail and killed the crew in areas that the T-Rex Couldn't reach.

(at around 7 mins) Malcolm claims that Ingen twisted the fact regarding the death of three people. This isn't necessarily a mistake. The crewman was killed before Malcolm and the others got to the island. Muldoon, Arnold and the lawyer were killed that he knew about. Nedry disappeared and nobody knew what happened to him, they could not have known that he died. Therefore, to Malcolm's knowledge only 3 people did die in Jurassic Park.

(at around 9 mins) Hammond state that Isla Nublar was just the "factory floor," while the animals were truly bred on Isla Sorna before being transported to the park. However, Jurassic Park (1993) featured a genetic lab with embryos in syringes and hatching baby dinosaurs, neither of which was ever supposed to have guests come inside. There are numerous inconsistencies between this movie and the others in the Jurassic Park series. However, since they do not compromise the movie's own internal structure they cannot, legitimately, be classed as goofs.

(at around 28 mins) Shortly after Dr. Malcolm discovers that Sarah Harding is on the island. She talks about studying the dinosaurs without any effect whatsoever. Dr. Malcolm states this as impossible due to the "Heisenberg Uncertainty Principle." This principle is related to quantum physics. It has been suggested that the correct principle is the "Hawthorne Effect", which states that a subject group being studied is affected from the simple fact that it is studied. However, the "Heisenberg Uncertainty Principle" includes a theory that the act of measuring something can change the value of whatever you are measuring, which fits into how Dr. Malcolm was talking about Sarah's scientific measurement causing the change in dinosaur behavior, not the kind of environment the dinosaur is in. Also, Dr. Malcolm would be more likely to know the Heisenberg Principle than the Hawthorne because of his line of work in chaos theory.

(at around 19 mins) Everyone is surprised when the barge captain reveals that the islands are called Las Cinco Muertes ("The Five Deaths"), even though the name is clearly marked on their map that we see on the wall of the truck. However, it is possible that Nick had simply not seen that map before leaving, and neither Ian or Eddie knew the English translation.

(at around 27 mins) When Sarah Harding is surrounded by the Stegosaurus, the front creature (the one that swipes its tail at her) is not reflected in the river's water.

(at around 1h 5 mins) When the Rexes attack Eddie in the car they bite the driver's seat off and it deploys the airbag. A real airbag would inflate much faster and with a different sound than the one in the movie. This is because the deployment of an actual airbag could seriously injure the actor; therefore, they created a slower inflating one which accounts for the change in sound as well.

(at around 1h 2 mins) When Sarah reaches up over the edge of the cliff to grab the rope, we see that the rope, which is supposedly holding the weight of three people, is clearly slack.

(at around 45 mins) After the released Triceratops smashes the conference tent in the InGen base camp, it stands over a flame for a moment before charging to the left. As it passes over a cowering workman there is a clear error in clipping in the CGI tail of the creature as it jumps from being in the background to the foreground over the workman's head.

(at around 1h 35 mins) When Kelly is doing her gymnastics in the shack before kicking the Raptor out, you can see the hand guards, on her hands, that gymnasts use.

(at around 1h 35 mins) Kelly's legs seem too short to have connected with the raptor while swinging around the pipe. She would have needed to let go and launch herself bodily at the reptile, then land on the grid. Instead, after it's impaled outside, she's still swinging around the pipe before doing a dismount to join her dad on the second level.

Even after discounting the foreshortening effect, the CGI missed the mark. Kelly's swing missed the raptor by at least a foot.

(at around 1h 30 mins) During the raptors attack, Ian jumps into and old Ford with the raptor crashing into the door. It rocked the vehicle hard enough to break the glass. As the window does start to break the raptor sticks its snout in the hole, cracking it and making it larger. In a car door this would be tempered glass, instantly shattering.

While the film portrays Nick van Owen as a hero, he violates not only Coast Rican law, he actively interferes with the efforts of a private company to take care of conflicts on its own property. And if the InGen had wanted to it, it could have easily had him prosecuted for the deaths of the employees who were killed during the animal hunts. The film veers away from this very obvious fact which is odd as InGen representative, Peter Ludlow, is not shown to be a very sympathetic, nor empathetic individual.

When the crew sees the InGen choppers approach the coast with vehicles hanging, Ian takes the binoculars and looks into the wrong end. It should make the choppers appear smaller, not larger.

(at around 34 minutes) Jeff Golbloom holds a pair of binoculars in the wrong direction, this would make it harder to see the writing on the helicopters, not easier.

(at around 1h 40 mins) Near the end of the film, while looking out the door of the helicopter, Nick says something to Ian and Sarah, but the dialog was removed.

(at around 1h 5 mins) When the two tyrannosaurs come back to attack Eddie when he is trying to save Sarah, Ian and Nick hanging from the cliff, it sounds like one of the Rex is screaming loud but none of their mouths open.

(at around 1h 50 mins) After Ian and Sarah have the infant T-Rex in the back seat of the red convertible, as Ian turns into the gas station, in Ian's rear-view mirror you can see a brief reflection of Steven Spielberg with baseball cap directing the scene.

(at around 48 mins) When Nick is carrying the baby T-Rex into the trailer, a cable can be seen going around the Rex's right leg and into Nicks jacket. This is probably for the animatronics.

(at around 1h 2 mins) During the trailer sequence, after the safety rope unties, the three characters can be seen being held up by wires after falling.

(at around 1h 35 mins) Before Kelly begins her giant swing in the cabin to knock out the raptors, you can clearly see the wires supporting her.

(at around 1h 35 mins) Obvious stunt double for Kelly during her gymnastic move before she kicks the velociraptor out the window.

(at around 19 mins) According to Hammond, Isla Sorna is supposed to be about 80 miles from Isla Nublar. According to the map, Sorna is the central island of "The Five Deaths", but none of the others are Nublar, and no other Islands are around for hundreds of miles.

(at around 2h) CNN correspondent mentioned the ship was 206 nautical miles (206NM) from its destination in Costa Rica, halfway there. Even in a straight line crossing over land, it's over 1300NM from San Diego to Costa Rica, way more than twice 206NM.

(at around 1h 30 mins) These islands are fictional, of course. Still, when Nick radios for help from the abandoned operations center, he gives Isla Sorna's latitude as "9 degrees, 58 minutes" north, and starts giving the longitude as "85 degrees". By itself, that would put Sorna within Costa Rica's mainland. Sorna is supposedly 87 miles SW of Isla Nublar (dubbed 120 miles west of Costa Rica), so to be in the Pacific, Sorna's longitude would need to be 88 or 89 degrees west instead.

(at around 1h 40 mins) During the press conference to present the T-rex, Ludlow thanks everyone for attending in "the wee small hours of the morning." However, when he enters the control room of the dock to check on the incoming barge, the clock above the window reads 9:26.

When InGen staff are exploring the ship carrying the T-Rex, they enter the wheel house and find a severed hand still holding onto the ship's wheel. The wheel house however is still intact - there is no way the T-Rex could have attacked and eaten the pilot without destroying the wheel house.

The team was told that they were to stick to the perimeter of the island, mainly the beach. However they end up on top of a cliff that is hundreds of feet high with no explanation of how or why they got there. Noone that has ever driven a motor home with a huge trailer would ever try to take it up there.

(at around 28 mins) When Ian, Nick, and Eddie first meet Sarah on the island she pets the baby dinosaur and then after escaping the parents she tells Nick to not light a cigarette and goes thru a long diatribe about how they can't interact with them including not even bending a blade of grass. So petting the dinosaur is completely contrary to what she is saying.

Despite being a supposed expert on animal behavior and study, Sarah Harding makes countless simple mistakes: she continues wearing a jacket covered in blood, which attracts the Tyrannosaurus, she changes the T-Rex's territory by helping Nick hold its child captive, and she approaches a young Stegosaurus, causing its parents to attack.

At 1:12 Sara's jacket has blood from the baby T-Rex on it. As an expert in working in nature she would know it would attract predators and would have disposed of it.

(at around 11 mins) Early in the film, when Dr Malcolm visits John Hammond in his house, Hammond tells Malcolm that he's putting a team on the ground on Isla Sorna to study the dinosaurs. Malcolm responds by asking which "four lunatics" he's "trying to con into this". Since Hammond has made absolutely no mention of the number of people on the team, and since Malcolm hadn't known the plan till a few seconds before, how would he know there were four?

Drawing on his experience as a field researcher, Malcolm made an accurate estimation of how many crew would be needed to accomplish Hammond's tasks.

(at around 16 mins) When Eddie Carr is first demonstrating the satellite phone equipment to Dr Malcolm, but can't get it to work. He is seen in the background holding the handset to his ear but has it the wrong way round, with the keypad against his cheek and the earpiece facing away from his ear. Being that Eddie Carr is the 'tech guy' for the expedition it is worrying that he gets this wrong.
