Audio problem: After the aeroplane crashed, a dinosaur stepped over it and the windows shattered making the typical sound of made-of-glass things when broken. I can tell everybody (I'm a pilot) it is not accurate because they are made of plexiglass (a sort of fibrous plastic).

Factual error: Not so much of a mistake, but I want one of those satellite phones. I have a mobile which I can't hear in my pocket, let alone a hundred meters away in the belly of a dinosaur or later buried in a mound of dino dung. There is no way a 2001 phone's tiny speaker could penetrate that much insulation.

Visible crew/equipment: When the group was flying into the island, there's a shot of the plane flying in front of the cloud, and there's the obvious shadow of the helicopter that filmed that shot!
