Corrected entry: In the scenes where they are flying over the herd, to the left of the screen you can see tracks made by continuous driving of vehicles. There was no recent vehicle traffic on the island so it should have regrown by now. (00:18:35)
Corrected entry: How did the pteranodons survive without lysine? According to Sarah's theory in the second film, the herbivores ate lysine rich plants and the carnivores ate the herbivores. However the pteranodons were in an enclosure so they could not get out to the herbivores and the herbivores could not get in to them. And the fish in the river did not carry lysine. (01:02:10 - 01:07:35)
Correction: Yes, they did. In fact lysine was a rubbish choice for a control device as it is very common in our diet. Foods rich in lysine include beef, turkey, cheese, vegetables, fruits, beans, mung bean sprouts, brewer's yeast, legumes, chicken, lamb... and fish.
Corrected entry: Amanda, Ben, and Eric were vacationing on the Costa Rican mainland, which, according to maps by JP experts, is 200+ miles away from Isla Sorna. So how is it possible that the speedboat in the first scene was able to make the trip by midday?
Correction: Without being too presumptuous, they could have left early.
Corrected entry: All of the dinosaurs in Jurassic Park III are radically different than the ones in the previous movies, most notably the Velociraptors, who have gone from being grayish brown to having wild color patterns of blue, red, green black and white, as well as having grown mohawks of feathers on their heads. It couldn't be evolution.
Correction: This takes place on a different island, as Eric (I believe, the younger guy) says once they crash. As we saw in the labs, the people weren't just breeding and hatching dinosaurs. They were playing god. The fetuses were in special fluid containers, so they could be "edited". Who's to say one of the scientists didn't colorize them and add feathers?
Corrected entry: In the scenes with the pteranodons, they actually lift up beating their wings. In reality, these dinosaurs are designed to float with the wind, having very small and fragile bones on their wings which do not allow them to beat them. As a matter of fact, to lift from the ground, they extended their wings and hoped that the wind itself would be strong enough to carry them, thus making it impossible for them to lift from the bridge in the giant birdcage or to beat their wings next to the plane.
Correction: All the bones in all modern flying birds are small and fragile when compared to the bones of non-flying creatures. Birds manage to beat their wings quite vigorously without damaging the bone structure so it's possible a pteradon could/would too. As no one has ever seen a live pteradon taking flight, the statement "they extended their wings and hoped that the wind itself would be strong enough to carry them," is mere speculation and as such can't really be called a mistake.
Corrected entry: Spinosaurus wasn't actually as deadly in real life as it was in the film. It is believed that its diet may have only been fish, and according to Dinosaur A to Z by Don Lesser, the spinosaurus' size was greatly exaggerated in the movie to make him seem deadlier.
Correction: Actually, this was done deliberately by InGen (Hammond's dino-making company.) Grant tells us this himself: Eric says, "I didn't think they came that big." Grant replies, "They don't." InGen had been messing with the dino's DNA.
Corrected entry: When they are trying to take off from the island, the run into the dinosaur and blood spatters on the glass. When they crash, the glass gets shattered. You can see that there is no blood on the glass anymore.
Correction: The blood is clearly seen running off the windscreen of the plane while the plane was still travelling (at a high speed) through the air. Just like water running off your windscreen of your car.
Corrected entry: Does Eric have hair clippers? He was on the island for 6 weeks or 8 weeks and his hair is the exact same length. Also, throughout the movie every single man remains clean-shaven.
Correction: He could have found some scissors from the island, considering all the other stuff he found. As for the men, they could have had some razor blades in their backpacks.
Corrected entry: In the end of the Lost World it shows a pteranodon land on a branch and look at the camera but then in Jurassic Park III they are all in cages. How does that work?
Correction: The island in this film was meant to be "the factory floor" where all the dinosaurs are produced and then shipped to the other island once they reach a certain age or if they're needed. The bird cage would have been built to stop an Ingen product from flying away until it was needed on the other island (where it would probably be put in another cage). Now if the people where told to leave the island (judging by what was left they did so in a bit of a hurry) they probably figured the dinos they were working on at the time wouldn't survive and left them to it and when people started to get killed on the island someone stepped in and made sure the pteranodons where locked in the cage before declaring the island off limits.
Corrected entry: In the scene where the Spinosaurus is chasing Grant and the boy along the giant fence, Grant and the boy think they have escaped by cutting through a small hole in the fence. This fence is actually a double fence, the first part appears to be made from two in steel cables and forms a mesh fence. The second part of the fence appears to be made from 10-12 inch steel tubing. After Grant and the boy escape through the hole the Spinosaurus back up, charges the fence and crashes through with ease. Grant and the rest of the survivors then dash into a nearby building and slam the door. They then lock the door with 3 sliding dead bolts about 2 inches thick. When the Spinosaurus pushes against the door, it's unable to break through the 2 inch deadbolts.
Correction: When it breaks through the fence, it can get the whole weight of its body behind it. If you look you can see it almost hits it with its shoulder in order to break it down. When it comes to the door, because of its low height it can only use its legs or possibly its head. Therefore it cannot put nearly as much force behind its hit on the door. We also have to consider the possibility that it broke bones or something when it smashed through the fence, so might not be up to the task.
Corrected entry: In the fight between the Tyrannosaurus and Spinosaurus, the Tyrannosaurus grabs the Spinosaur by the neck with its jaws. Now, Tyrannosaur's jaws had enough muscle power to crush bone. That bite would've killed the spinosaurus. On the other side, the Spinosaur has very weak jaws for a large carnivore-it couldn't have killed the Tyrannosaur.
Correction: These aren't true dinosaurs, they've been engineered to be how In-gen wants them (to a degree). In the first Jurassic Park book theres a passage where Hammond and Dr. Wu have a arguement about the Raptors and their intelligence (should they leave them as they are or change it so they're easier to manage).
Corrected entry: In the opening scene when they are flying over the island, Ben looks down at the boat crew and finds that they have disappeared. He has a camera in his right hand. He tells the kid not to worry. He puts his hand behind his back for a split second and voila- his camera is gone. He had no time to put attach it to his backpack. In a later scene, we find that Ben has been holding onto the camera the whole time. That's odd because it disappeared earlier.
Correction: The camera is actually on a string or band and you can see it swinging just behind his back, after he lets go. The reason we later see footage of the kid saying "The camera's still on" is because Ben didn't stop recording after he let go of the camera.
Corrected entry: Grant was exposed to tear gas when Eric saved him...he didn't inhale much but he would still be coughing so violently that he wouldn't be able to speak coherently or eat without problem for quite a few hours at least.
Correction: That was a smoke grenade, not a tear gas canister.
Corrected entry: When the crew finds the video camera and then realize it is out of battery power, the remaining pilot says, 'I have an idea.' He then begins to unscrew the flashlight, presumably to put those batteries into the video camera. One problem: the video camera on hand doesn't take the kind of batteries found in the flashlight.
Correction: If you actually watch the rest of the scene you can plainly see two yellow wires connected from the flashlight to the camera.
Corrected entry: The raptors in this film have evolved, allowing the males to have quills on their necks. That's fine and dandy, but when Grant is having his dream scene on the plane, and sees the raptor sitting next to him, it has the quills. Shouldn't it have looked like the ones he saw in the original Jurassic Park? He wouldn't have known about the quills.
Correction: Dinosaurs were related to birds, and many species (including the raptors) may have had feathers (the "quills" that seen on the male raptors). Although the raptors in the first movie lacked feathers (either as a mistake, or perhaps its a gender-based thing), if you assume Dr. Grant continued studying raptors after the first incident, he may have learned that the species had feathers and adjusted his dream accordingly.
Corrected entry: How is it that Billy manages to beat the whole group in getting to the shore when they left him a good 12 hour boat trip away? I'm sure the navy didn't venture into the pteranodon cage to get him and then go back out to the shore.
Correction: After the characters escape the bird cage you see the deadbolt thing open. This is the way of foreshadowing that Billy escaped because it shows that he opened the lock. He beat everyone to the beach because they had to stop in the fight with the spino and were delayed by the egg-giving-up ceremony.
But he was badly injured; how could he have moved that quickly?
Correction: You see Billy went down a waterfall. What is more likely is that InGen tapped into a water system to fill the area for fish. This could make 2 exits. The one Billy gets carried down (as all rivers lead to the ocean) and the one Grant swims down. As the military doesn't know where to look and a foot search is out of the question, the military likely went up the rivers and found Billy, who could have told them to check the other side, which is why there is military so close to where Grant and the others show up.
Corrected entry: The boy in the film had collected urine from a T-rex to keep raptors away. There's a problem with that: dinosaurs were reptiles and were related to birds. Birds and reptiles do not urinate like mammals; they excrete uric acid together with their faeces through a single excretory opening called a cloaca.
Correction: There's a lot of assumptions there. We can't be sure whether or not dinosaurs urinated, it seems unwise to assume they did not merely because modern reptiles and birds don't.
Corrected entry: Do you remember that annoying cell phone? Well, it's supposed to be owned by Paul Kirby. Then why is it that Udesky has one JUST like that one with the SAME annoying song in the part when they are testing the weapons?
Correction: Mr. Kirby probably gave Udesky the satelite phone as a means of contacting him before they set out for the island.
Corrected entry: At the beginning we see the crew of the speed boat pass through fog, when they come out the speedboat is in tatters and the crew are dead. But what killed them? They were too far out at sea, and the Pteranodons were locked in their cage.
Correction: The Spinosaurus killed them. It can swim discretely, which we see later in the movie, and it must have snuck up on them and eaten them. It had enough time to get to the center of the island by the time Dr. Grant and the rest arrive.
Corrected entry: When Eric is dropped from the Pteranodon into its nest, we see that the nest and the adjacent rocks are littered with human bones and skulls. It's quite unlikely anyone has been there until now, so where did those human bones come from?
Correction: There has quite been a significant amount of human activity on the island - shown by the buildings and vehicles (trucks/boats) which appear throughout the film. Presumably some of the humans who built these structures could have been eaten by the pteranodons.
Correction: The tracks could also be animal tracks. Herds of animals could still be using the tracks made previously by vehicles.
