Continuity mistake: In the scene where all of the characters are flying over the dinosaur island, you can clearly see power lines and poles on one of the hills. The island ran all facilities off generators, and would not have this type of power transmission.
Continuity mistake: As the group runs into the aviary, they slam the metal doors shut, bolting them. The spinosaurus repeatedly bashes the doors from the other side. However, you can see through the small gap along the top of the doors that there is nothing that big behind them, not even a shadow is moving; there is only open space and daylight.
Continuity mistake: Tea Leoni's bruise on her cheek changes throughout the movie, once looking like a scratch, once looking like a bruise, etc.
Continuity mistake: At the very end of the movie when the group is cornered by the Raptors, Tea Leoni gives them the eggs. When the first raptor picks up the first egg it is safe in its mouth, but in the next shot it is barely in its mouth, then in the final shot when the Raptor runs away, if you look closely at the Raptor's mouth the egg is well into the mouth.
Continuity mistake: The plane the group flies in is identified on the outside as a King Air 200. In the inside shots, the windows are from another type aircraft as the window shades are pull down types and in the King Air the windows are tinted by rotating a plexiglass cover to dim the light. Also, the engine sounds are from a piston aeroplane and this plane is definitely a turbo prop.
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 spinosaurus is chasing Grant and the kid and hits the fence the sun changes between shots.
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.
