Plot hole: The spinosaurus manages to smash through a metal reinforced wall designed to stop dinosaurs getting past it without too much effort, yet it can't get through a wooden gate secured by some metal bars. It makes no sense.

My favorite one outa of all of them
Dr. Alan Grant: Well, you're alive, and that's the important thing. And thanks to you, that's one thing we have in common. Did you read Malcolm's book?
Eric Kirby: Yeah.
Dr. Alan: So?
Eric: I...I don't know. I mean, it was kinda preachy. Too much chaos, everything's chaos. Seemed like the guy was kinda high on himself.
Dr. Alan: Well, that's two things we have in common.
Trivia: Dr. Grant's brown truck with the Museum of the Rockies and Montana State University logos on it is the actual vehicle that belongs to Dr. Jack Horner, paleontologist consultant on the Jurassic Park films as well as the man that the character of Grant is based on.
Question: In the end, the Pterosaurs fly away from Isla Sorna for a new home. Where on Earth would they go and wouldn't they attack and kill any human or animal there?
Answer: The island was located west of Costa Rica in the pacific so its likely they are headed for the Americas or Galapagos islands. They won't likely start hunting on animals and humans as they are thought to be fish eaters and thus would stay near the coast and avoid contact with land animals, especially predators. The reason they attack the humans in the bird cage is because of malnutrition and captivity related stress.
Wrong argument, because in Jurassic World, we see them attacking humans.
For the same reason I have given earlier, probably. You don't see them eating humans in any case.





Suggested correction: The Spinosaurus used its full body force to smash the fence. The gate, being a smaller target, was too small for the Spinosaurus to use its full body force.
