Visible crew/equipment: Once inside the abandoned building on the island they proceed to walk down some steps after the candy machines. The upper body of a lurking crew member can be seen in a lit doorway in the background of the shot as the group descend the metal staircase. (00:39:39)
Plot hole: When the party is attempting to take off after first attracting the attention of the Spinosaurus, no way Cooper could make it to the end of the runway before the plane does.
Revealing mistake: When father and son are parasailing, in the close-ups (an obvious green screen effect) the clouds never change shape, note the small one on the left, revealing it's a still image.
Continuity mistake: After a guy shoots at an abandoned jet, the objective lens still shows the plane undamaged, as it was before he fired.
Continuity mistake: When Sattler, Mark and Grant are at home, the mug in Sattler's hands suddenly disappears.
Continuity mistake: When the boat carrying the parasailing guys is about to crash, the sky keeps swapping between cloudy and sunny depending on the shot.
Continuity mistake: When the front of the plane is ripped off, there are 2 people sat in the pilot and co pilot seat. As the camera changes one of them has disappeared from the seat and is further back in the plane. (00:24:50)
Continuity mistake: When the spinosaurus is chasing Grant and the kid and hits the fence the sun changes between shots.
Other mistake: When the plane drops out of the tree with the tail going down and all the people in the tail, it crashes and the metal actually crushes upward. There is no way that those people could walk out of that plane uninjured.
Factual error: When they find the camcorder and discover the battery is dead, Udesky takes the batteries from his Maglite, and they magically work in the camcorder.
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.
